Streszczenie:

Aspects of the physiological ecology of pike from an upland Scottish loch have been studied. A small laboratory stock was maintained in a healthy, feeding condition to allow measurements of a range of physiological and behavioural parameters. Resting and maximum metabolic rates increase with body size and the relationship between weight and oxygen consumption can be described by regression equations of the form: Y = ax⁶. The ratio of resting : maximum oxygen consumption (the metabolic expansibility coefficient) increases with body-weight. Heart rate increases during activity and feeding, accurately reflecting fluctuations in metabolic rate; so it can be used as a measure of metabolic rate in the field using heart rate telemetry techniques. For pike in the laboratory, the relationship between heart rate and oxygen consumption (VO₂, mg/h standardised to a 500g fish weight) can be described by a significant regression valid for heart rates below 55 beats/min. Post-prandial oxygen consumption was measured directly in small pike (< 300g) or calculated in large pike from heart rate. Peak post-prandial oxygen consumption was found to utilise the total metabolic scope in small pike but not larger individuals. Weight specific peak post-pradial oxygen consumption decreases with increasing pike size; consequently smaller pike have the physiological capability to grow more quickly. In adult pike metabolic scope cannot be fully utilised by a combination of the maximum power demands of food processing and aerobic swimming; there seems to be a generous allowance for the metabolic demands of recovery from burst activity. Analysis of the electrocardiogram (ECG) indicates that pike show a reflex bradycardia in response to most sensory stimuli. Amplitude of the ECG increases after feeding events and following burst activity. The interval between Q and T waves of the ECG decreases as heart rate increases reflecting changes in the time for ventricular systole. A telemetry system for monitoring heart rate and movements of free-swimming wild pike has been developed and field tested. A preliminary track of movements by a pike over several days indicated that activity levels in the wild are low, however the fish was by no means sedentary. Using data from this and other studies of pike, a hypothesis is put forward that whilst young pike tend to maximise growth rates, adults feed well within their physiological limits for feeding and growth over much of the year, even in the presence of excess prey. It is suggested that sub-maximal feeding may have a selective advantage through decreasing mortality probability and increasing lifetime reproductive output.

Streszczenie:

Fast-starts are high powered events of short duration, used by fish for prey capture and escape from predation. Here, the energetic cost of fast-starts in escape and prey capture for a fast-start specialist, the northern pike, Esox lucius, are determined and physiological and behavioural constraints assessed. This is done by comparing costs with literature values for physiological limits set my muscle mechanics and biochemistry, and comparing costs with other components of the energy budget. The combination of high speed film analysis (200-250Hz) and hydrodynamic models are used to determine the mechanical costs, hydrodynamic efficiencies and power output of fast-starts in prey capture (S-starts) and escape behaviour (C-starts). Excess post-exercise oxygen consumption (EPOC) is used to estimate the metabolic cost of fast-starts. A comparison of model predictions with required (acceleration) force estimates shows results are within 22% and similar to previous findings at lower film speeds. The caudal region including the caudal, dorsal and anal fins contribute the most to thrust (>90%) and the dorsal and anal fins contribute 28%. Due to the necessity for deceleration of fin sections during each tail beat, kinematics are not always optimal as predicted by the Weihs model. Mechanical power output, hydrodynamic efficiency and kinematic parameters (maximum velocities and maximum angle of attack of the caudal fin) are determined for fast-starts during prey capture and escape. Hydrodynamic efficiency averages 0.37 (range: 0.34 to 0.39) for C-starts and 0.27 (range: 0.16 to 0.37) for S-starts. The acceleration of added mass contributes the most to power output at 39%. Power output and efficiency for S-starts are more variable than C-starts and hydromechanical efficiency increases with number of tail beats for S-starts. Maximum muscle power output and maximum muscle stress during fast-starts in comparison to literature values for muscle function shows muscle power output during fast-starts is at its physiological limit but muscle stress is not. Metabolic efficiency is higher at 0.094 for C-starts than S-starts at 0.047. However, muscle efficiency estimates are similar averaging 0.252 for both fast-start types. Mean energetic cost of fast-starts is determined to be 26.5 J/kg for C-starts and 18.6 J/kg for S-starts. Based on the observation that pike can repeatedly fast-start up to 170 times before becoming exhausted and on estimates of available energy reserves from literature values for ATP and CrP concentrations in white muscle, the duration of fast-starts is concluded to not be limited by muscle physiology. Average power output is found to be similar for C and S-starts at 406 to 412 W/kg. Only hydrolysis of ATP and CrP can supply energy at this rate. Therefore, based on fish white muscle biochemistry and mechanics, power output during fast-starts appears to be limited by muscle physiology. The cost of fast-starts represents 0.03 to 2% of maintenance costs for pike and therefore only 5 to 30 fast-starts per day would be required to increase the daily energy budget by 10%. In addition, the cost of fast-starts represents 0.52 to 27.4% of surplus energy available from assimilated prey. Therefore, the cost of fast-starts can be significant and reducing fast-start duration is a probable strategy for minimising activity costs and thus increasing the energy available for growth or reproduction.

Streszczenie:

Accelerometer biologgers är ett verktyg för att identifiera beteenden hos djur. För att kunna använda accelerometern effektivt är det viktigt att träna en maskin–inlärning algoritm för att kunna identifiera olika beteenden utifrån accelerations data. Denna studie testar om accelerometer går att effektivt använda på gäddan (Esox lucious) för att kunna identifiera de olika beteendena för att senare kunna användas på en stor skalig studie. Fem gäddor användes i studien och varje gädda hade en accelerometer i sin kroppshålighet. Gäddorna var filmade i en pool och data användes för att träna en maskin-inlärnings algoritm för att identifiera åtta beteenden, simmar, simmar tillsammans med andra gäddor, hantering av byte, inaktivitet, skrämd/flyr, lyckad attack, misslyckad attack och attack mot en annan gädda. Studien visar att det går att se skillnad mellan beteendena till en viss gräns. Inaktivitet, simmar och de olika attackerna kunde skiljas åt. Det gick inte att se skillnad mellan simmar och simmar tillsammans samt se skillnad mellan de olika attackerna. Flykt kan blandas ihop med simmar och attackerna. För att se skillnad mellan lyckad och misslyckad attack kan hantering av byte användas för att identifiera lyckad attack, dock funkar bara då bytet inte sväljs helt. Programmet behöver mer träning för att inte missta flykt och de olika attackerna med hantering av byte. Studien visar att accelerometer kan användas på en större skala, huvudsakligen för att se skillnad mellan inaktivitet, attacker och simmar.
Acceleration biologgers are tools to measure activity in animals and to identify behavioural modes. To use this technology efficiently it is important to train a machine learning algorithm to identify behavioural modes from acceleration data. This study test this technology on the Northern pike (Esox luscious) to determine if it is possible to measure pike behaviour in larger field’s studies. To do this five Northern pike was caught and implanted with accelerometers. The pikes were filmed in a pool with the accelerometer in their body cavity and the data was used to train a machine learning algorithm to identify eight behaviours, swimming, swimming together with other pikes, attacking other pikes, fleeing/scared, successful attack, unsuccessful attack, prey handling and inactivity (sleeping, waiting etc.). Inactive, swimming and the three attacks can be differentiated. Swimming and swimming together could not as well for the three different attacks. To differentiate successful attack and unsuccessful attack prey handling can help to identify successful attack. This only works if the prey was not swallowed directly. The results are promising as it indicates that with practice the program can be used at a larger scale field study to identify inactivity, swimming and attacks.

Streszczenie:

The population of northern pike in the Baltic sea has seen a drasticdecrease in numbers in the last couple of decades. The reasons for this are believed to be many, but the majority of them are most likely anthropogenic. Today, many measures are being taken to prevent further decline of pike populations, ranging from nutrient runoff control to habitat restoration. This inevitably gives rise to the problem addressed in this project, namely: how can we best monitor pike populations so that it is possible to accurately assess and verify the effects of these measures over the coming decades? Pike is currently monitored in Sweden by employing expensive and ineffective manual methods of individual marking of pike by a handful of experts. This project provides evidence that such methods could be replaced by a Convolutional Neural Network (CNN), an automatic artificial intelligence system, which can be taught how to identify pike individuals based on their unique patterns. A neural net simulates the functions of neurons in the human brain, which allows it to perform a range of tasks, while a CNN is a neural net specialized for this type of visual recognition task. The results show that the CNN trained in this project can identify pike individuals in the provided data set with upwards of 90% accuracy, with much potential for improvement.

Streszczenie:

Pharmaceutical contamination is increasing in the environment and the consequences this will bring are of growing concern. The highest contamination of pharmaceuticals can be found in aquatic ecosystems and the organisms of these systems are therefore of utmost importance to research in order to understand the ecological consequences of pharmaceutical contamination. This report will reveal the effect contamination can have on an important apex predator often found in temperate aquatic systems, the Northern pike (Esox lucius) when exposed to the psychiatric pharmaceutical Oxazepam. The predatory performance of pike was studied before and after Oxazepam exposure by monitoring how fast each pike caught three prey of roach (Rutilus rutilus), as well as observing the amount of failed predation attempts when hunting the roach. The exposed pike displayed more failed predation attempts after exposure as opposed to the control group. Furthermore it took the exposed pike longer to catch all three roach after exposure while the mean for the control group decreased. Hence, Oxazepam exposure seem to have an effect on predation performance of pike but no definite conclusion could be drawn about to which extent this affects the foraging success and thereby the survival of the pike considering the complex nature of aquatic systems. More studies are therefore needed in order to determine the full effect pharmaceutical contamination can have on complex aquatic ecosystems and more specifically on an apex predator.

Streszczenie:

Population divergence shaped by natural selection is central to evolutionary ecology research and has been in focus since Darwin formulated “The origin of species”. Still, the process of adaptive divergence among sympatric populations is poorly understood. In this thesis I studied patterns of adaptive divergence among subpopulations of pike (Esox lucius) that are sympatric in the Baltic Sea but become short-term allopatric during spawning and initial juvenile growth in freshwater streams. I also examined causes and consequences of phenotypic variation among individuals within subpopulations to evaluate the contribution of natural selection to population divergence. I first investigated homing behaviour and population structures of pike to assess the potential for adaptive divergence among sympatric pike that migrate to spawn in different streams. Mark-recapture data suggested that migrating pike displayed homing behaviour and repeatedly returned to the same stream. Analyses of microsatellite data revealed partial reproductive isolation among subpopulations spawning in different streams. These subpopulations, however, were truly sympatric during the life-stage spent in the Baltic Sea. To address whether short-term allopatry has resulted in adaptive divergence among sympatric subpopulations I combined observational, experimental and molecular approaches. Observational data showed that subpopulations differed in morphological and life-history traits and common-garden experiments suggested that differences were, at least in part, genetically based. Moreover, QST-FST comparisons indicated that genetically based phenotypic differences has been driven by divergent selection, and a reciprocal translocation experiment showed that phenotypic variation represented local adaptations to spawning habitats. Finally, longitudinal and cross-sectional comparisons among individuals revealed associations between phenotypes, performance and fitness components. In conclusion, my thesis illustrates how short-term allopatry due to migratory behaviour can result in adaptive divergence among sympatric subpopulations. These findings advance the understanding of evolutionary processes at the finest spatiotemporal scale and illustrate that local adaptations can arise in environments with high connectivity. The results also emphasise that fine spatial scale population structures must be taken into consideration in management and conservation of biodiversity in the Baltic Sea.

Streszczenie:

Distributional movements of subpopulations may act as a buffer to prevent the loss of a species in a certain area. However, within subpopulations adaptations may evolve that makes the inhabitants of a certain habitat to better cope with prevailing environmental conditions. If such traits are related to reproduction, they may reduce the opportunity of gene exchange between other subpopulations. Also, a lack of adaptations to a specific habitat may be what prevents a group of individuals, arriving from an adjacent habitat, to successfully colonize an area where a previous subpopulation has been lost.This is the report from a field study conducted in the wetland Lake Långsjön, that in 2018 was restored in order to promote the recruitment of anadromous pike (Esox lucius) to the Baltic Sea. Commonly, wetlands that are restored to promote anadromous pike recruitment, are constructed so that they enable spawning migration from the sea towards the wetland and juvenile emigration towards the sea only. In that sense Lake Långsjön is different, from other wetlands restored for the same purpose, due to that it is connected to both the Baltic Sea and an upstream located freshwater lake. By quantifying the migration of pike (spawners and juveniles) in both directions I explore the consequences that the regained connectivity between the Lake Långsjön and the coast may have on the population dynamics within this wetland; (i) whether it is potentially influenced by allowing mixture between pike with different migratory strategies for spawning (anadromous and potamodromous), (ii) what drivers there are of pike fry emigration and how they may influence the pike fry emigration route and (iii) whether or not the pike of potamodromous origin, resident in the upstream located lake, may work as a source, providing the Baltic Sea with pike juveniles. Pike spawners arriving in the wetland were caught in traps between March - April. Pike fry were caught withing the wetland with fyke nets and by netting. Emigrating pike fry were caught in fyke nets. Findings suggest that spawning migration patterns do not differ between anadromous and potamodromous pike. However, the spawners arriving from the Baltic Sea I suggested are to be composed by offspring of potamodromous origin, possibly hatched during the previous season, and that they as juveniles swam downstream. This, in turn, indicates that the potamodromous stock can help establish an anadromous stock in the Baltic Sea. Still, due to the observation of pike fry displaying an emigration behaviour upstream, origin is identified as a factor that may influence the pike fry emigration route. Also, this emigration pattern seems to indicate a heritable trait that has not been described before among pike, that of downstream spawning. The restoration of the wetland and the regained connectivity is key, both for the ability to restock the Baltic Sea with pike juveniles but also to ensure the conservation of a fascinating stock of pike exhibiting a unique spawning strategy

Streszczenie:

The work submitted in this thesis describes three investigations of the relationship between stimuli, the pike and the pike's inclination to feed. Consideration is given to the importance of relating internal and external factors to the causation of behaviour. The effects of individual pike and the time lapsed after feeding on predatory behaviour are firstly assessed. Use of multivariate analysis determined key behaviours in the repertoire of pike that could be successfully employed in analysing prey-capture sequences. The modifying influence of hunger, as categorised by stomach content, on prey capture sequences is presented and discriminant function analysis is used as a method of describing differences in predatory behaviour. A simple treatment of bout criteria is also given. The interaction of the components of visual stimuli and its influence on predatory response revealed that particular movements and shape of a stimulus altered the attack behaviour of pike. The relative strength of a visual cue, for example, how "fish-like" a stimulus is, has dependence on how inclined an individual is to feed. A view of how these factors influence the behaviour of pike in a wider context is expressed.

Streszczenie:

Gäddan (Esox lucius) är en toppredator och nyckelart som är beroende av grunda och vegetationsrika rekryteringsmiljöer. Dessa miljöer hyser risk att minska i sjöar med mänsklig påverkan, vilket i sin tur skulle kunna leda till lägre överlevnad hos gäddlarver och yngel till följd av intraspecifik konkurrens av föda. Under två veckors tid undersöktes överlevnaden hos gäddyngel (< 30 mm, medellängd = 20 mm) i relation till täthet, för tätheter mellan 2-20 individer/m2, fördelat i 10 burar placerade i en naturlig uppväxtmiljö. Jag fann ett signifikant negativt samband mellan täthet och överlevnad i burarna, där en ökad täthet miskade överlevnaden av gäddyngel. Täthetsberoende tillväxt kunde inte konstateras hos gäddynglen, men de två längsta individerna och individerna med högst individuell tillväxt återfanns vid högst- respektive näst högst initial täthet. Mina resultat stöder hypotesen att överlevnaden är täthetsberoende för gäddlarver i en naturlig rekryteringsmiljö, och bidrar med kunskap att ta hänsyn till vid förvaltning av gäddpopulationer.
Pike (Esox lucius) is a top predator keystone species dependent on shallow, vegetated areas for recruitment. These types of habitats stand at risk of reduction in human impacted lakes, which in turn could lead to lower survival of pike fry and -larvae due to intraspecific competition for food. During a time period of two weeks, the survival of pike fry (< 30 mm, mean length = 20 mm) was studied in relation to fry densities between 2-20 pike/m2, in 10 enclosures placed in a natural nursery habitat. I found that survival of pike-fry within the enclosures was significantly negatively correlated to initial stocking density, where an increase in density led to lower survival of pike fry. No evidence of density dependence was found for growth of pike fry, although the two longest fry and fry with the highest individual length increase were found at the highest- and second highest initial densities. The results support my hypothesis that the survival of pike fry is density dependent in a natural nursery habitat, and provides further knowledge for consideration in population management of pike.

La tesi verte sull’attività politica e filosofica di Seneca. Si dimostra che Seneca fu un politico, che fece uso della proprie conoscenze filosofiche come di un instrumentum regni, prima, quando fu il maestro di Nerone (durante il cosiddetto Quinquennium felix), in seguito, quando compose le Epistulae Morales ad Lucilium. Con questo corpus di lettere Seneca ambiva a fornire un’educazione etica ai futuri leaders politici, che avrebbero dovuto governare conformemente alla filosofia stoica. Inoltre, nella tesi si dimostra che Seneca considerava la poltica come un instrumentum philosophiae, in quanto attraverso l’attività politica la contemplazione filosofica si volge in azione, che guida l’esistenza umana. La seconda parte della tesi fornisce un commento lemmatico, filosofico, storico e stilistico, dell’Epistula 94.1-51. In questo testo Seneca esprime la propria visione progressita della vita individuale e sociale. Suggerisce inoltre di guardare a lui come all’Agrippa di Età neroniana, impegnato a combattere contro la decadenza morale di Roma. Seneca ci consegna anche la chiave di accesso alla comprensione del Principato neroniano, con particolare attenzione posta alla Domus Aurea.
This thesis focuses on Seneca’s political and philosophical work. I show that Seneca was a politician who made use of his philosophical knowledge as an instrumentum regni, before, when he was Nero’s tutor (during the so-called Quinquennium felix), after, when he wrote his Epistulae Morales ad Lucilium. With his body of letters, he aimed to provide ethical education to future political leaders ruling according to Stoic philosophy. Moreover, this thesis shows that Seneca regarded politics as an istrumentum philosophiae, as through politics philosophical contemplation turns into action, directing human life. The second part of this thesis provides a lemmatic philosophical, historical and stylistic commentary of Seneca’s Epistula 94.1-51. In this letter Seneca confers his progressive view of individual and social life. He also suggests to us to regard himself as the Neronian Agrippa, busy fighting against moral decadence in Rome. He also gives us the key to understand the Neronian Age, in greater detail the Domus Aurea.

Streszczenie:

Ce travail porte sur les rythmes d'activité du brochet. La complexité des activités comportementales nous a conduits à prendre en compte cinq états : la nage, le repos, l'affut, le fond et la prise alimentaire. Les résultats ont été obtenus à partir d'enregistrements vidéos sous différentes conditions photopériodiques (ld : 12. 12. Dd. Ll) et analysés à l'aide de traitements statistiques adéquats. Ces outils mathématiques nous ont permis de mettre en évidence des rythmicités ultradiennes, circadiennes et infradiennes. Tout d'abord des périodes comprises entre 14h et 34h ont été recherchées. En ld 12. 12, les états comportementaux présentent un rythme circadien, sauf la prise alimentaire qui a lieu à n'importe quel moment du nycthémère. En dd nous avons décelé, pour la nage, le repos et l'affut, la présence d'une période propre de l'ordre de 30h. En ll, c'est seulement pour une intensité lumineuse de l'ordre de 0,26 wm 2 que des manifestations rythmiques ont pu être révélées. Pour des animaux élevés en ld : 12. 12, des oscillations circadiennes sont mises en évidence lors de l'étude expérimentale en lumière permanente. Par contre, pour des brochets élevés en lumière permanente, c'est un rythme infradien qui est observé. Nous avons par la suite étendu notre étude au domaine ultradien pour des périodes comprises entre 1h et 14h. Il faut souligner que cette approche est assez nouvelle puisqu'à notre connaissance aucune étude, dans le domaine ultradien, n'a été réalisée chez les poissons. Seuls les comportements de nage et de fond présentent des oscillations ultradiennes de l'ordre de 2h50, 5h40 ou 8. Bien que nous soyons encore loin d'une compréhension générale, la discussion finale aborde les relations susceptibles d'exister entre les activités rythmiques comportementales et l'organisation des oscillateurs sous-jacents

In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland. The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established.

Streszczenie:

Lucius Cornelius Sulla wrote an autobiographical account of his controversial career which, although it was left incomplete on his death in 78 BC, nonetheless had an incalculably significant influence on writers during the subsequent centuries. The Autobiography has not survived intact, but the twenty-three remaining fragments reveal a great deal about the original structure and contents of the work. Through the medium of commentaries on each of the fragments, this thesis considers the function and role of this lost text in Sulla’s self-representation strategy. Sulla was a man who was intensely interested in and concerned with managing the ways in which he was perceived both by his contemporaries and by posterity; although the evidence for this strategy is diverse and problematic, it is nevertheless possible to reconstruct the most important ways in which Sulla engaged with different groups. Through coinage, inscriptions, monuments, and nomenclature, Sulla exerted great effort in establishing a public image of himself as a man favoured by the gods, justified in his actions, and whose actions had brought great prosperity to Rome; this was so intricate and thorough that it can be termed ‘propaganda’. It was in the Autobiography, however, that Sulla was able to develop these themes. By presenting a comprehensive reconsideration of his life and career, Sulla was able to create a complex character portrait of himself, and engaged in self-justification, confronting many of the negative interpretations of his actions that had already begun to develop. Through analysis of the fragments of the Autobiography, therefore, this thesis asks important questions concerning the nature of self-representation and propaganda in the late Republic and the role of religious discourse within political negotiation in this period, and offers new insights into the intellectual world of Rome in the early first century BC.

Antalet ryggkotor varierar kraftigt mellan olika taxa, men också inom arter eller populationer. Omfattande forskning har visat att antalet ryggkotor hos fisk är resultatet av interaktioner mellan genetisk struktur och plastiska svar på miljöbetingelser under individens ontogeni. Ett vanligt mönster är tendensen för antalet ryggkotor att variera med kroppsform och/eller kroppslängd hos fisken. Gäddan (Esox lucius) i Östersjön har en komplex populationsstruktur, bestående av flera genetiskt distinkta subpopulationer, vilka utgörs av anadroma individer som uppvisar ett homing-beteende. Individer som tillhör dessa subpopulationer är sympatriska större delen av året och blir allopatriska endast kortvarigt under tiden för lek. Den här studien undersökte fördelningen av antalet ryggkotor hos tre anadroma sympatriska subpopulationer av gädda iÖstersjön. Signifikanta skillnader i fördelningen av antalet ryggkotor hittades både inom och mellan alla undersökta subpopulationer och åldersklasser. Resultaten från ett ”common-garden” experiment antydde att skillnader i antalet ryggkotor mellan olika subpopulationer delvis hade en genetisk basis, vilket indikerar möjligheten för selektion att verka på denna egenskap, och en potentiellt evolutionär förändring. En kvadratisk regression visade på ett kurvilinjärt samband mellan antalet ryggkotor och kroppslängd hos juveniler. Tillsammans tyfrt dessa resultat på att de kombinerade effekterna av stabiliserande och divergent selektion kan ha spelat en roll i fördelningen av antalet ryggkotor hos gäddan i Östersjön. Fördelningen av antalet ryggkotor inom subpopulationer verkar vara under inflytande av stabiliserande selektion. Skillnader mellan subpopulationer kan istället reflektera lokala anpassningar som drivs av divergent selektion. Dessa fynd signalerar behovet av att betrakta varje subpopulation som en egen enhet i bevarandebiologiska sammanhang.
Vertebral number (VN) is known to vary greatly across different taxa, but also within species orpopulations. Extensive research has shown that VN in fish is the result of interactions between geneticstructure and plastic responses to environmental cues during ontogeny. A frequently reported pattern is the tendency for VN to vary with body shape and/or length of the fish. The pike (Esox lucius) of the Baltic Sea has a complex population structure, with genetically distinct subpopulations consisting of homing anadromous individuals. Individuals belonging to these subpopulations are sympatric for most of their lives and become allopatric briefly during spawning each year. This study examined the distribution of VN in three anadromous sympatric subpopulations of pike in the Baltic. Significant differences in VN were found between juveniles and adults belonging to different subpopulations, but also across life-stageswithin all three subpopulations. Results from a common-garden experiment indicated that differences in VN among subpopulations were in part the result of genetic differences, indicative of evolutionary change. Furthermore, a quadratic regression revealed a curvilinear relationship between VN and bodylength of juveniles. Taken together, these results suggest that the combined effects of stabilizing and divergent selection might have played a role in shaping the distribution of VN in pike of the Baltic. The distribution of VN within subpopulations seems to be under the influence of stabilizing selection. Differences among subpopulations might instead reflect local adaptations driven by divergent selection. These findings signal the need for conservationists to view these subpopulations as unique units of management.

Streszczenie:

Basal metabolic rate (BMR), the sum of maintenance energy costs, represents a major component of the energy budgets of ectothermic vertebrates and varies between individuals within a species. Individual ectotherms are generally assumed to have a constant BMR at any given temperature. A strategy of flexibility in BMR might have evolved to cope with differing environmental conditions. Within-individual variation in BMR was examined in two fishes, juvenile Atlantic salmon Salmo salar and juvenile northern pike Esox lucius, whilst the effects of exercise and ration on BMR, maximum metabolic rate (MMR), enzyme levels and body composition were studied in detail for pike. In the first part of the study, measurements of BMR were made for first-summer Atlantic salmon parr at rest by respirometry. In 1996, initial measurements of BMR were made for 25 fish held in a stock tank. Fish were then allocated in small groups to channels to represent a change in environment and BMR re-measured after a period of several weeks. The procedure was repeated for 30 fish in the summer of 1997, when fish were given a reduced food ration. Variation in BMR in each experiment was analysed for individual fish, and for all fish using a linear mixed model. There were statistically significant differences in BMR values between the two times, the within-individual, between-time variation representing approximately ± 21% of BMR in 1996 and ± 28% of BMR in 1997. Reduced-rafion fish (1997) displayed a significant decrease in the mean elevation of the allometric scaling relationship between body mass and BMR between time periods. To further explore possible mechanisms for flexibility in BMR and relationships with MMR, juvenile pike were used. Initial measurements of BMR and MMR (following exhaustive exercise) were made and factorial metabolic scope calculated (MMR/BMR). Fish were then split into a high ration no-exercise group (n = 10), low ration no-exercise group (n = 10) and sustained exercise group (n = 13). Initial measurements were termed time 1, with subsequent measurements made after approximately 3 weeks (time 2) and 11 weeks (time 3). Exercised fish had a significantly larger MMR and scope following 3 weeks of sustained swimming. For all fish there were significant correlations between BMR and MMR at times 1 and 3 but not at time 2.After the oxygen measurements made at time 3 all fish were humanely killed. Maximal enzyme assays were performed on six tissues for each remaining fish (n = 30). Levels of each of two enzymes (citrate synthase, CS, and lactate dehydrogenase, LDH, measured in the direction of lactate oxidation) were found to be similar between treatment groups for respective tissues. Total CS activity levels and LDH levels were highest in the heart and red muscle. In general there was little difference in the relative organ masses of fish exposed to different treatments. It is concluded that in these two fish species with very different life styles, between- and within- individual variation in BMR (salmon & pike) and MMR (pike only) is apparent and that differences in ration and exercise influence individual physiology.

L'objectif de cette thèse a été de déterminer la pertinence des lâchers comme mode de gestion des pêcheries récréatives de brochet (Esox lucius). Une synthèse bibliographique a d'abord permis d'identifier les potentialités et les risques liés aux lâchers de brochets. La construction d'une vaste base de données sur les lâchers et sa mise en relation avec des données de pêche électrique a permis de démontrer que les lâchers ont un effet positive sur l'occurrence du brochet mais pas d'effet sur son abondance malgré que l'efficacité des lâchers augmente avec la taille des poissons lâchés. Deux études génétiques ont permis de mettre en évidence un fort taux d'hybrides permis les juvéniles et un taux relativement modéré parmi les adultes. D'une manière générale, les lâchers un bon potentiel d'amélioration des pêcheries mais présentent des risques pour la conservation de l'espèce. Ce travail se termine par des recommandations sur l'usage des lâchers et une réflexion sur les stratégies alternatives de gestion
The objective of this PhD was to determine the relevance of stocking for pike (Esox lucius) recreational fisheries management. First, we identified benefits (for recreation) and risks (for conservation) of stocking of pike through a bibliographic review. Second, we used a large dataset (96 sites, 6 years) to evaluate the actual and potential effects of stocking on pike populations. We found that pike stocking programs actually positively affect pike occurrences but not pike abundance despite we found that the effect of stocking on pike abundance increases with the size of the stocked pike. Third, we measured the genetic impact of stocking. We found a high rate of hybridization among juveniles but a moderate rate of hybridization among adult pike. Overall, stocking has good potential to enhance fisheries yet it carries conservation risks. We conclude with recommendations for the use of stocking and discussion about alternative management strategies

Streszczenie:

Film is commonly used to estimate the fast-start performance of fish. An analysis of hypothetical, film-derived, and accelerometer-measured acceleration-time data of fish fast-starts indicates that the total error in film studies is the sum of the sampling frequency error (i.e., the error due to over-smoothing at low film speeds) and measurement error. The error in film based studies on the acceleration performance of fish is estimated to be about 33 to 100% of the maximum acceleration, suggesting that other methods of estimating acceleration should be employed. The escape performance of rainbow trout Oncorhynchus mykiss and northern pike Esox lucius (mean lengths 0.32 m and 0.38 m, respectively) were measured here with subcutaneously implanted accelerometers. Acceleration-time plots reveal two types of escape fast-starts for trout and three for pike. Simultaneous high-speed ciné films demonstrate a kinematic basis for these differences. Trout performing C-shaped fast-starts produce a unimodal acceleration-time plot (type I), while during S-shaped fast-starts a bimodal acceleration-time plot (type II) results. Pike also exhibit similar type I and II fast-starts, but also execute a second S-shaped fast-start that does not involve a net change of direction. This is characterized by a trimodal acceleration-time plot (type III). Intraspecific and interspecific comparisons of displacement, time, mean and maximum velocity, and mean and maximum acceleration rate indicate that fast-start performance is significantly higher for pike than for trout, for all performance parameters. This indicates that performance is related to body form. Overall mean maximum acceleration rates for pike were 120.2 ± 20 m s⁻² (x ± 2S.E.) and 59.7 ± 8.3 m s⁻² for trout. Performance values directly measured from the accelerometers exceed those previously reported. Maximum acceleration rates for single events reach 97.8 m s⁻² and 244.9 m s⁻² for trout and pike, respectively. Maximum final velocities of 7.06 m s⁻¹ (18.95 L s⁻¹, where L is body length) were observed for pike and 4.19 m s⁻¹ (13.09 L s⁻¹) for trout; overall mean maximum velocities were 2.77 m s⁻¹ for trout and 3.97 m s⁻¹ for pike. The fast-start performance of pike during prey capture was also measured with subcutaneously implanted accelerometers. Acceleration-time plots and simultaneous high-speed cin6 films reveal four behaviours with characteristic kinematics and mechanics. As for the escape data, fast-start types are identified by the number of large peaks that appear in the acceleration-time and velocity-time data. Comparisons of mean performance were made between each type of feeding fast-start. Type I fast-starts were of significantly (i.e., p < 0.05) shorter duration (0.084 s) and displacement (0.132 m) than type III (0.148 s and 0.235 m) and type IV (0.189 s and 0.307 m) behaviours, and higher mean and maximum acceleration (38.6 and 130.3 m s⁻², respectively) than the type II (26.6 and 95.8 m s⁻²), type III (22.0 and 91.2 m s⁻²), and type IV (18.0 and 66.6 m s⁻²) behaviours. The type II behaviours were also of shorter duration and displacement, and of higher mean acceleration than type IV fast-starts, and were of significantly shorter duration than the type LU behaviours. Prey capture performance was compared to escapes by the same individuals. When data are combined, regardless of mechanical type, mean acceleration (37.6 versus 25.5 m s⁻²), maximum acceleration (120.2 versus 95.9 m s⁻²), mean velocity (1.90 versus 1.57 m s⁻¹), and maximum velocity (3.97 versus 3.09 m s⁻¹) were larger, and duration shorter (0.108 versus 0.133 s) during escapes than during prey capture. No differences were found through independent comparisons of the performance of feeding and escape types II and III, but type I escapes had significantly higher mean velocity (2.27 versus 1.58 m s⁻¹), maximum velocity (4.70 versus 3.12 m s⁻¹), and mean acceleration (54.7 versus 38.6 m s⁻²) than the type I feeding behaviours. Prey capture performance was also related to prey size, apparent prey size (defined as the angular size of the prey on the pike's retina), and strike distance (the distance from the pike to the prey at the onset of the fast-start). Mean and maximum acceleration increased with apparent size and decreased with strike distance, while the duration of the event increased with strike distance and decreased with apparent size. No relation was found between the actual prey size and any performance parameter. Strike distance ranged from 0.087 to 0.439 m, and decreased as the apparent size increased from 2.6 to 9.9° (r² = 0.75). The type I behaviour was usually employed when the strike distance was small and the prey appeared large. As strike distance increased and apparent size decreased, there was a progressive selection of type II, then III, then IV behaviours.
