Numerous environmental, nutritionnal and populationnal factors are likely to be involved in the quality of reproduction in fish. The objective of this PhD study was to determine and ranking the importance of the effects of these factors and their interactions on the determinism of the quality of reproduction in Eurasian perch, Perca fluviatilis. A first factorial experiment aimed at identifying the factors acting of the induction of the reproductive cycle. 8 two-levels factors were tested (amplitude of temperature decrease, timing, kinetics and amplitude of photoperiod decrease, handling, initial nutritional state, feeding and light spectrum). It was confirmed that temperature and photoperiod decreases are the two main cues inducing the reproductive cycle. Handling stress appears to be the most important factor modulating vitellogenesis. A second factorial experiment testing 8 two-levels factors (temperature, nutritional state, handling, dawn, light intensity, food type, feeding and photoperiod) dealt with the quality of reproduction (sperm, eggs and broodstock mortality). No spawning was obtained. This suggests that the photothermal program of control of the reproductive cycle could be inadequate. Sperm quality appears to be mainly affected by nutritional state and light intensity. High mortalities were observed and their determinism could be complex. A first qualitative model of the determinism of the quality of reproduction is proposed

The aim of these experimental studies was to improve our knowledge on the environmental control of Eurasian perch reproduction. Under a constant photoperiod (12L : 12D), thermal variations (6 weeks of cooling from 22 to 6ʿC, 5 months of chilling at 6ʿC and 1 month of warming from 6 à 14ʿC) have shown some limits on the control of the reproductive cycle. Even if aIl the males were spermiating after a such regime, only few females have developed their gonads (31 %) and only 6 % have spawned. Moreover, the spawning quality was low. Thus, the influence of photoperiodic variations in the control of female gametogenesis was suggested and studied. A 24 hours photophase inhibits the initiation of perch male and female reproductive cycle. Some low sex steroids levels were measured. A constant photoperiod (16L: 8D) results in a very heterogeneous gonad development, lots of atresia, and few spawnings (30 %). Under a natural photoperiod, results, in terms of plasma sex steroids variations, gonad development and eggs and larvae quality, were similar to those observed in natural habitat. In simulated photoperiod conditions, although all the broodstocks have developed their gonads, only 55 % of the mature females have spawned and low fertilization rates were observed. Spawning seems to be triggered off by seasonal temperature and daily light intensity variations. Most of the spawnings occurred at dawn. In artificial light conditions, the sudden switch from darkness to daylight could disturb the oviposition process. The light-darkness cycle would be an important factor, but not sufficient to induce a normal gonadal development. Daylength variations are also involved in the initiation and the gonadal development during gametogenesis. Photoperiodic and temperature variations both play a crucial roIe in the success of perch reproduction. Finally, in April, while the water temperature rises, a high mortality increase was observed. It seems to be not linked to the reproductive cycle

The Mirgenbach reservoir created by pumping water from the river Moselle in 1985 is a safety reservoiir and a buffer zone for the Cattenom nuclear power plant (Moselle, north-east France). With its maximum depth of 20 meters, this reservoir is characterized by its heated waters and the absence of a thermo-stratification. It is an ecological study of this lake-reservoir which contributes to the knowledge of the fish population and the demography of an initially dominant species : the perch, perca fluviatilis. From 1987 to 1991, various fishing techniques were employed on the Mirgenbach lake-reservoir. Two kinds of gill nets were used : traditional nets and vertical nets which took samples from the water surface to the bottom. A set of vertical nets were immersed in stations during fishing sessions spread along the year. Among the various fishing gears used, vertical gill nets turned out to the best sampling device for the analysis of the perch demography. The analysis of catches thanks to these various fishing gears enabled us to know its location and its evolution in the lake-reservoir. All in all, 18 fish species were identified with a majority of perch (perc fluviatilis), roach (rutilus rutilus) and common bream (abramis brama). The multiple correspondence analysis led us to distinguish several groups of stations, each having its own species. The sampled fish with traditional and vertical gill nets as well as angling enabled us to know the selectivity of each device and to study the demographic structure evolution. The number of catches has decreased dramatically within this period. The seasonal repartition of the species in the reservoir was studied is an annual cycle with vertical gill nets. The best catches of this carnivorous fish were made in summer, except in a littoral station close to a spawning area before reproduction time. The vertical distribution of this species according to bathymetry. The perches were found mostly at the bottom of the stations closest to the shore and from the bottom to the surface in the pelagic stations. The reproductive study of the perch is based upon weight index and the maturity stage index. Age is identified by the application of scalimetrie and operculometrie methods. The two corresponding structures can be used equally to describe the perch growth. In the Mirgenbach reservoir, the reproduction of the perch takes place from mid-march to mid-april. Perch may spawn since the end of february. Spawning period takes place precociously one month earlier than in other ponds of the region Lorraine. Males are mature at one year old and females at two years, with an intermediate fecundity for almost fish. In comparison with others lakes, the perch growth is faster in the Mirgenbach reservoir : it reaches 12 cm at one year. This growth speed depends upon the very good thermal conditions and a better availability of food resources with the decreasing of its population. Digestive contents are analysed to study the diet of perch. Perca fluviatilis fed on Crustacean with a selective predation on the cladocera Daphnia longispina, insects mostly chironomes larvae and nymphes, molluscs gasteropodes and fish such as roach (rutilus rutilus), ruffe (gymnocephalus cernua). Cannibalism occurs within perch in the reservoir. Nevertheless, diet depends upon sex and perch length and also seasons. A bibliographic review and a discussion on this Mirgenbach reservoir enables us to compare our results to others

This PhD thesis has determined the respective roles of photoperiod and temperature at the different and successive steps of the reproductive cycle (induction of the cycle, wintering period, spawning) in female Eurasian perch Perca fluviatilis. Photoperiod is the main environmental factor which synchronizes the onset of the reproduction cycle in Eurasian perch female, temperature plays only a modulating role. A high photoperiod decrease of 4 or 8 hours is recommended. The maintenance of constant photoperiod based on a long photophase (17L: 7D) delays the onset of the reproductive cycle, whereas the maintenance of a warm and constant temperature (22-23°C) does not delay it. For the wintering period, a photoperiod with a short daylight period (8L : 16D) is required. Concerning the effect of temperature variations, a high and progressive temperature decrease (from 22 to 6°C over 16 weeks) is recommended to ensure a complete ovarian development (all oocytes achieved the advanced vitellogenesis stage at the end of the induction phase and and final maturation stage just before spawning). Slight temperature decreases (from 22 to 14-18°C) alter the reproduction, especially during the chilling period (wintering period). The final increase of temperature (up to 14°C) after the wintering period is the main factor for spawning synchronization. This study allowed the development of a reliable photo-thermal protocol for out-of-season spawning with very high rates (close to 100%) of female response and spawning

Improving fish reproduction in breeding conditions implies to understand intrinsic and extrinsic factors influencing gametes quality on the one hand and to define relevant parameters allowing the prediction of fish reproductive performance on the other hand. Our goal was thus to understand the multifactorial determinism of the common perch (Perca fluviatilis) reproduction. Four nutritional factors (type of food and rate of rationing used either during the induction or vernalization phases) and 3 populational factors (initial weight, geographic origin and domestication level of breeders) have been tested. Data show different responses between females and males. type of food during wintering phase and initial broodstock weigh modified female condition. Males have been sensitive to rationing during wintering phase as well as geographical origin. Data show also that spawning rate was under the influence of interaction between kind of food during wintering phase and induction whereas geographical origin modulated the spawning date. The regulation of the performance reproduction is also a complex mechanism influenced by several factors. The second part of this work consisted on the research of parameters potentially predictive of ova quality. Firstly, our work shows that morphometric parameters measured before the fertilization are poorly relevant to predict reproductive performance. However, the proteomic analysis of several spawn allowed us to highlight proteins differently expressed according to the spawn quality, such proteins could be ova quality biomarkers

Currently, the durability of the aquaculture developmental model is clearly challenged and one solution consists to diversify the fish production by the domestication of new species such as the Eurasian perch (P. fluviatilis), a freshwater species promising and valuable for the diversification of European aquaculture. Several aspects of its reproductive biology are well known, nevertheless, only little information is available on its development. However, early developmental impairments, whose causes are unclear, actually impact the fish production quality. In this context, the present work aimed to characterize the developmental success and impairments in Eurasian perch on three main issues: (i) determine a model of normal embryogenesis table helping to (ii) define developmental impairments, in diverse rearing conditions and (iii) identify the relationships between various parameters of embryonic ontogenesis to characterize different patterns of developmental success. The first part of this study allowed identifying the accurate timing of normal ontogenesis of this species through the definition of an alternative and flexible developmental table to describe non-model fish species, allowing the intra- and inter-specific comparisons. In the second part, the exhaustive characterization of abnormal phenotypes revealed 10 categories of deformities linked to specific organs or functions. Moreover, some of these categories seemed to be related to rearing-conditions of the breeders allowing identifying the potential effects of extrinsic factors on the development and improving the management of fish. Finally, the previous results and the parameters measured during embryogenesis help to classify the several spawns obtained with the same developmental pattern and to highlight the potential relationships between diverse phenotypes and parameters. In addition, the data analyses showed that only 3 parameters are reliable to assess the developmental success: survival rate at the onset of the organogenesis, hatching and deformities rates. Henceforth, these parameters and this classification could be generalized as a new strategy to assess the developmental success in other fish species. All of these results provide a good basic knowledge to study the potential effects of various extrinsic and/or intrinsic factors on the developmental success and the embryonic quality

The study of teleost reproduction is fundamental in order to understand the future of ichthyologic populations, determinant for the balance in aquatic environments, and this, in a context of global warming which will affect distribution zones of species as well as their reproductive strategies in order to guarantee survival of their progeny. Sexual maturation in pumpkinseed (Lepomis gibbosus) has been studied in an artificial basin in north-eastern France (Mirgenbach Reservoir) which receives over-heated water from the Cattenom nuclear power plant. Pumpkinseed, a centrarchid fish specie, is native to North America but has been introduced in Europe in 1880. Since its introduction, it has colonized the entire French hydrographic network. This specie, predominantly littoral, is already established in at least 28 countries in Europe and Asia Minor, but is currently considered to be invasive mainly in southern and central Europe. In our study, the reproductive effort was studied in both sex, using gonado-somatic index (GSI) and gonadal maturity stages obtained from histological observations. Growth and longevity have also been studied. A sample of 162 females and 157 males was collected for this work. In this context of warm thermal environment, sexual maturation is precocious compared to other pumpkinseed populations located at similar latitudes (age at maturity: 1 year), and the males mature one month before the females. The juvenile growth rate is high (LT>70mm at 1 year old), except for the small male cuckolders, but longevity (3 years) is lower than at the other sites in Europe (4 to 8 years). This precocity was also observed in other species at sites receiving over-heated nuclear plant discharge water, however oocyte abnormalities were observed which was not the case for the pumpkinseed population in the Reservoir Mirgenbach. The thermal conditions of the Mirgenbach Reservoir confer to this site a good opportunity to evaluate the consequences of the Global Warming on fish biology
