Abstract (sommario):
The protozoan parasite Cryptosporidium (class Gregarinomorphea, subclass Cryptogregaria) causes a range of symptoms in humans and clinical signs in animals from asymptomatic to severe diarrhoea and death. However, relatively little information is available regarding the taxonomy, zoonotic potential and host relationships of Cryptosporidium in fish. Previous studies have indicated that extensive genetic diversity exists with piscine Cryptosporidium species and genotypes. The present study screened fish from two sources in Perth, Western Australia; Water Garden Life Fish Farm (n=233) and Vebas Aquarium (n=234) for Cryptosporidium. Intestinal and gastric tissue was dissected out and screened by PCR and Sanger sequencing using Cryptosporidium specific primers that amplify DNA at the 18S and actin loci. Samples that were positive by PCR were also screened by histology. The overall prevalence of Cryptosporidium was 4.3% (20/467, 95% CI: 2.6-6.5). Phylogenetic analyses of 18S sequences identified C. huwi (n=11), piscine genotype 2 (n=3), piscine genotype 4 (n=1) and piscine genotype 7 (n=5). In addition, ten novel sequences most genetically similar to species from the genus Goussia and a sequence from the non-parasitic alveolate Colpodella were identified. Sequences amplified at the actin locus were C. huwi (n=7), piscine genotype 2 (n=1), piscine genotype 7 (n=1) and one novel Cryptosporidium sequence. Piscine genotype 2 was most closely related to piscine genotype 4 (4.1% genetic distance) and exhibited 11.1-11.9%, 15.3% and 22.3% genetic distances from C. molnari, C. huwi and C. scophthtalmi, respectively. At the actin locus, piscine genotype 2 was again most closely related to piscine genotype 4 (7.2% genetic distance) and exhibited genetic distances ranging from 18.1% (C. molnari) to 20% (C. huwi) and 26.1% for C. scophthalmi, respectively, and 20.7%- 32% genetic distance from all other species. Phylogenetic analysis of concatenated 18S and actin sequences showed that piscine genotype 2 exhibited 14% (C. molnari) to 24.6% (C. canis) genetic distance from all other Cryptosporidium spp. Using concatenated sequences, piscine genotype 7 was most closely related to C. huwi at a genetic distance of 7.5% and exhibited 13.4% (C. molnari) to 23.1% (C. scophthalmi) genetic distances from other piscine Cryptosporidium species, with 17.9% (C. testudinis) to 22.6% (C. canis) genetic distance from all non-piscine Cryptosporidium species. Piscine genotype 2 exhibited 14.6% genetic distance from piscine genotype 7. These genetic distances at two separate loci confirm the genetic distinctness of piscine genotype 2 and piscine genotype 7 and indicate that they are likely novel species. Additionally, 10/467 (2.1%, 95% CI; 1.0-3.9) samples that were positive at the 18S locus, produced sequences most genetically similar to species from the genus Goussia, subclass Conoidasida, nine were novel sequences and were compared at the 18S locus to established species of Goussia and genetic distances between 1.9% and 14.8% were identified, adding to the diversity of this genus. Furthermore, Schyzocotyle acheilognathi, the invasive Asian fish tapeworm, was identified (n=2) by morphology infecting goldfish from a local fish farm. This is only the second report of S. acheilognathi in Western Australia as it was first discovered in 2018 by a Murdoch researcher in feral goldfish from a Lake in Joondalup. Analysis at additional loci or whole genome sequencing will shed more light on the evolutionary relationships between Cryptosporidium species, while next generation sequencing would elucidate the prevalence of mixed infections of Cryptosporidium in fish. The genetic data produced by the present study describes two piscine genotypes of Cryptosporidium (that are likely valid species) in detail and provides new genetic data on the diversity of Goussia spp. Keywords: Cryptosporidium, 18S, actin, Schyzocotyle acheilognathi, Goussia

Abstract (sommario):
Growth typically varies considerably amongst the individuals in a population and between individuals in different populations of the same species, especially when those populations are found in environments in which the characteristics differ markedly. Although the annuli in hard structures are often used to age fish, such growth zones are not always clearly defined in these structures. Thus, in these cases, it is necessary to use alternative methods for ageing, such as analysis of modal progressions in length-frequency data. However, these types of techniques can usually only identify distinct size classes that correspond to an age class. They thus only enable an individual fish to be aged when it is a member of a discrete size cohort. Such a situation generally only applies to the younger age classes. This thesis reports the results of studies on a species that can be aged using the annuli in one of its hard parts (asteriscus otoliths), i.e. Cnidoglanis macrocephalus, and four species (Amniataba caudavitatta, Apogon rueppellii, Pseudogobius olorum and Favionigobius lateralis) for which it was necessary to use a method such as length-frequency analysis for ageing. Cnidoglanis macrocephalus is an important recreational and commercial species caught in coastal marine and estuarine environments in south-western Australia. However, all previous detailed studies on the age and growth on this species have focused on estuarine populations. This thesis reports the results of a study of the biology of C. macrocephalus in Princess Royal Harbour, a marine embayment on the south coast of Western Australia. Samples of C. macrocephalus were collected from amongst the macroalgae that were removed from this highly eutrophic embayment by mechanical harvesters. Analysis of the reproductive and size composition data derived from these catches showed that spawning occurs between October and December and that fecundity ranged from 75 in a 384 mm fish to 465 in a 443 mm fish. Small fish (<200 mm) were rarely caught, reflecting the fact that the young of this species are difficult to capture. Analysis of the trends exhibited by the marginal increments on otoliths showed that the number of annuli on this hard structure could be used to age C. macrocephalus. The samples of C. macrocephalus collected from Princess Royal Harbour contained female and male fish that had lived for up to 10 and 9 years in age and reached maximum lengths and weights of 523 mm and 745.3 g and 557 mm and 735.8 g, respectively. To overcome the paucity of small fish, von Bertalanffy growth curves were constructed using back-calculated lengths and employing the scale proportional hypothesis and body proportional hypothesis (see Francis 1990). The growth rates of females and males were slower than those in a nearby seasonally closed estuary (Wilson Inlet) and in a permanently open estuary on the lower west coast of Australia (Swan River Estuary). Yield per recruit analyses were conducted in order to ascertain what minimum legal lengths were appropriate for the capture of C. macrocephalus in Princess Royal Harbour, the Swan River Estuary and Wilson Inlet in order to sustain the stocks in those water bodies. The age and growth of Amniataba caudavittata and Apogon rueppellii in the Swan River Estuary were determined by analysing the trends exhibited by modes in sequential monthly length-frequency data. This was achieved by employing MULTIFAN, which constrained the means of the lengths of the cohorts in successive monthly samples to a seasonal form of the von Bertalanffy growth curve. The resulting growth parameters derived by MULTIFAN were similar to those derived from the growth curves fitted to the means of the cohorts determined independently for each monthly sample by MIX. The discreteness of the distributions and modes of size classes in length-frequency data for A. caudavittata and A. rueppellii enabled sound growth curves to be constructed for both of these species. The growth curves of these two sexes of both species were significantly different, with K being lower and L being higher for females. The trends exhibited by these growth curves emphasised that the growth of both species is highly seasonal, with little or no increase in length occurring during the cooler part of the year. The seasonal von Bertalanffy growth equations implied that 'negative growth' occurred in winter, but this is an artefact produced by size-related differences in offshore movements that occur at that time of the year. The age and growth of two further species from the Swan River Estuary, Pseudogobius olorum and Favonigobius lateralis, were also studied. Since P. olorum and F. lateralis both spawn at different times of the year and these times (spring and autumn) are not regularly spaced during the year, they produce new 0+ recruits at two irregularly-spaced times of the year. Consequently, MUTLIFAN cannot be used to analyse the size-distribution data for these two gobiid species. Thus, MIX was used to identify the size classes present in sequential samples and to provide means for the length distributions of those size classes. von Bertalanffy growth equations were then fitted to the mean lengths at the inferred age of the males and females of each size class of each species. It was found appropriate to use the traditional von Bertalanffy growth curve for describing the growth of the product of the spring-spawning group of both species and a seasonal von Bertalanffy growth curve for that of the product of the autumn-spawning groups of both species. The growth curves, when considered in conjunction with the trends exhibited by reproductive variables, demonstrate that female F. lateralis attains sexual maturity more rapidly and at a larger size than P. olorum. The majority of the female and male progeny of the summer and autumn-spawning groups of F. lateralis reach maturity when they are approximately 3 1/2 and 8 1/2 months old, respectively, compared with five and seven months old, respectively, for P. olorum. Models, incorporating data on water temperature and salinity and the growth and reproduction characteristics of P. olorum and F. lateralis, were used to postulate how environmental factors might be regulating when these two gobiid species spawn. The results of these models support the conclusion that the bimodal timing of spawning of P. olorum in the upper estuary was regulated by water temperature, with spawning occurring between 20 and 25oC but inhibited by temperatures greater than 25oC. They also showed that, although water temperature also influenced the timing of spawning of F. lateralis in the lower estuary, the onset of spawning by this species only occurred when salinities had reached 300/00.

Abstract (sommario):
Invasions of non-native species cause problems in ecosystems worldwide, and despite the extensive effort that has been put into research about invasions, we still lack a good understanding for why some, but not other, communities resist these invasions. In this doctoral thesis I test hypotheses on biotic resistance using a large dataset of more than 1000 both failed and successful introductions of freshwater fish into Swedish lakes. We have found that the classic species richness hypothesis is a poor descriptor of introduction success because it fails to acknowledge that resident species contribute to the resistance in different ways. We developed a new measure of biotic resistance, the weighted species richness, which takes into account that the resident species contributes to the resistance with different strength and sign. Further, we correlated performance traits of species in their role as an invader and as a resident species to predict how the biotic resistance of these communities would develop over time. We found a positive correlation between performance traits: Some species have high introduction success, they make a large contribution to the resistance, and they cause extinctions when introduced but do not go extinct themselves when other species establishes, whereas other species are weak performers in these respects. Thus, the biotic resistance of these communities should grow stronger as non-native species accumulates. These results give us clues about what type of communities that should be most sensitive to further invasions, i.e., communities harboring species weak performers.  My results show that the biotic resistance of communities is an important factor in determining invasibility of a community. They also show that methods for quantifying resistance must take into account how interactions are structured in nature. What determine the biotic resistance of a community is the type of interactions that the resident species have with the invader and not the species richness of the community.

Europeans are regular consumers of fish and aquaculture products. Therefore, five species of potential aquaculture rearing named: Meagre, Pikeperch, Grey Mullet, Greater Amberjack and Wreckfish were selected for new product development. This work incorporated opinions of both experts and naïve assessors thus, including specific demands and consumer preferences, in selected markets of the European Union (UK, Germany, Spain, France and Italy). Different fish product prototypes were developed from the fish species accordingly with suggested ideas and based on the physicochemical and sensory properties of the selected species. Six of these products were chosen, based on their level of processing and addressed market. Consumers perception of all six of them was also assessed in the five selected countries. As it turned out the image/perception of the different products, differed in an important way between countries, as well as their impact on the product acceptance and purchase probability

Abstract (sommario):
Gymnotiformes are South American weakly electric fish that produce weak electric organ discharges (EOD) for orientation, foraging and communication purposes. Because EOD properties vary widely across species, electric signals could serve a species recognition function. We quantified the electric signals of various species and used discriminant function analyses to verify whether these signals are species-specific based on different signal parameters. We found that the EOD waveform was a more specific cue than EOD frequency. Using Apteronotus leptorhynchus as a focal species, we complemented these measurements with playback experiments using stimuli of different species (varying in frequency, waveform, or both). In both a free-swimming experiment and a communication assay with restrained fish, we found that the subjects' behaviour was strongly influenced by the frequency of the stimuli but, opposite to what we predicted, the waveform of the stimuli had no measurable effect on either communication or locomotor behaviors.
Les gymnotes sont des poisons faiblement électriques d'Amérique du Sud utilisant leur électro-sens à des fins de navigation, d'approvisionnement et de communication. Les décharges électriques varient énormément d'une espèce à l'autre et pourrait ainsi être utilisées pour la reconnaissance des espèces. Nous avons quantifié la décharge de plusieurs espèces et avons utilisé des analyses discriminantes afin de vérifier si les décharges sont spécifiques aux espèces selon différents paramètres. La forme de la décharge semble plus spécifique que la fréquence de celle-ci. Pourtant, en réalisant des expériences comportementales avec le gymnote Apteronotus leptorhynchus et des stimuli de différentes espèces, nous avons découvert que le comportement des sujets varie beaucoup en fonction de la fréquence du stimulus alors que, contrairement à ce que nous avions prédis, la forme de la décharge du stimulus n'eut aucun impact mesurable sur les comportements moteurs ou communicatifs des sujets.

Abstract (sommario):
Corydoras aeneus is an armoured catfish found in the upper amazon regions of South America. It is a member of the family Callichthyidae. Studies done with this species of fish showed that C. aeneus is a tetraploid with a chromosome number of 132 (Scheel et al. , 1972). Dunham et al. (1980) reported 120 chromosomes. The C. aeneus used in this study were bought from direct importers. We had four samples of fishes supposedly coming from Brazil (Belem), Guyana, Peru and Trinidad. During our initial studies in an attempt to karyotype aeneus we came across individuals with a highly reduced chromosome number. A diploid form of C. aeneus was discovered. Only those fishes from our Belem sample were diploid. A comparison of the diploid and tetraploid forms was done. Both forms were karyotyped, the tetraploid form of C. aeneus has 134 chromosomes and the diploid has 56. Physically both forms looked exactly the same. Morphometric as well as meristic data was collected from 131 fishes and analyzed by multivariate, discriminant and contingency chi- square analyses. The results obtained do not suggest any absolute morphological differences between the diploid and the tetraploid forms anymore than between tetraploids.

Abstract (sommario):
This dissertation focused in the comprehensive analysis of the capabilities of some non-tested types of Artificial Neural Networks, specifically: the Probabilistic Neural Networks (PNN) and the Multi-Layer Perceptron (MLP) Ensembles. The analysis of the capabilities of these techniques was performed using the native brown trout (Salmo trutta; Linnaeus, 1758), the bermejuela (Achondrostoma arcasii; Robalo, Almada, Levy & Doadrio, 2006) and the redfin barbel (Barbus haasi; Mertens, 1925) as target species. The analyses focused in the predictive capabilities, the interpretability of the models and the effect of the excess of zeros in the training datasets, which for presence-absence models is directly related to the concept of data prevalence (i.e. proportion of presence instances in the training dataset). Finally, the effect of the spatial scale (i.e. micro-scale or microhabitat scale and meso-scale) in the habitat suitability models and consequently in the e-flow assessment was studied in the last chapter.

Los análisis se centraron en la capacidad de predicción, la interpretabilidad de los modelos y el efecto del exceso de ceros en las bases de datos de entrenamiento, la así llamada prevalencia de los datos (i.e. la proporción de casos de presencia sobre el conjunto total). Finalmente, el efecto de la escala (micro-escala o escala de microhábitat y meso-escala) en los modelos de idoneidad del hábitat y consecuentemente en la evaluación de caudales ambientales se estudió en el último capítulo.

Les anàlisis sobre les capacitats d'aquestes tècniques es varen desenvolupar emprant la truita comuna (Salmo trutta; Linnaeus, 1758), la madrilla roja (Achondrostoma arcasii; Robalo, Almada, Levy & Doadrio, 2006) i el barb cua-roig (Barbus haasi; Mertens, 1925) com a especies objecte d'estudi. Les anàlisi se centraren en la capacitat predictiva, interpretabilitat dels models i en l'efecte de l'excés de zeros a la base de dades d'entrenament, l'anomenada prevalença de les dades (i.e. la proporció de casos de presència sobre el conjunt total). Finalment, l'efecte de la escala (micro-escala o microhàbitat i meso-escala) en els models d'idoneïtat de l'hàbitat i conseqüentment en l'avaluació de cabals ambientals es va estudiar a l'últim capítol.

Abstract (sommario):
Before the installation of marine renewable energy devices, fish species and abundance should be examined for selecting the proper site where the effects of the devices on the environment and fish will be as small as possible. Fish species and abundance can be examined in a variety of methods such as a fish finder using an acoustic wave and fishing gears such as a gill net. However, the fish finder cannot specify the species of fish that is sometimes estimated from the experience of fishermen or scientific researchers. Some amounts of fish must be removed from the target sea area in case of using the fishing gear, while the species of fish can be specified. In the present study, an underwater optical video camera is combined with the fish finder using an acoustic wave to specify the species of fish. A circular fish-eye digital video camera is inserted into a waterproof container. A part of the container is made of glass in a dome shape for the circular fish-eye lens. The container is attached to polyethylene ropes and is towed by a fishing vessel. First, the hydrodynamic characteristics of the container was examined by a towing test with the three kinds of towing speed in a water tank. Then the container was towed in the real sea, which is the demonstration site of offshore wind and wave energy developments off Kamaishi of Iwate Prefecture. The depth of the video camera with the container was not constant since the moving speed of the fishing vessel was slow and fluctuating. The image of video camera could be captured successfully together with that of the acoustic video camera, while fish could not be found in both the optical and acoustic measurements in the present investigation. The investigation will be continued, and the effects of transparency of water should be discussed as future works. Also the actual or model fish should be captured by the underwater video camera to evaluate if it can specify the species of fish.

Abstract (sommario):
This special report provides a selection process for choosing priority species using the specific focus of high-elevation, forested habitats in the North Atlantic to demonstrate the process. This process includes criteria for choosing invasive species to incorporate into models, given the predicted spread of invasive plant species because of climate change. Discussed in this report are the US Army Corps of Engineers’ Threatened and Endangered Species Team portal, the US Fish and Wildlife Service’s Information for Planning and Consultation Portal, the nonprofit organization Partners in Flight’s watch list, the US Geological Survey’s Biodiversity Information Serving Our Nation model, and NatureServe’s interagency effort Landfire. The data linked this montane habitat with a species of conservation concern, Cartharus bicknelli and the endangered squirrel Glaucomys sabrinus as target species and with Elaeagnus umbellate, Robinia pseudoacacia, Rhamnus cathartica, and Acer planoides as invasive species. Incorporating these links into the climate change framework developed by Davis et al. (2018) will create predictive models for the impacts of climate change on TER-S, which will affect land management decisions in the region.

Testo completo
Abstract (sommario):
Herons and egrets commonly cause damage at aquaculture facilities and recreational fishing waters where fish are held at high densities. Fish-eating birds also can have an impact on intensively managed sport fisheries. Damage occurs when herons and egrets feed on fish purchased and released for recreational sport fishing activities. Values of these fish can be quite high given the intensity of management activities and the direct relationship of fishery quality to property value. Herons and egrets are freshwater or coastal birds of the family Ardeidae. Herons and egrets discussed in this section are all piscivorous. They are opportunistic feeders, however, and will consume small amphibians, insects, and reptiles. Due to these food preferences, herons and egrets are attracted to shallow lakes and human-made impoundments. Native bird species are covered under the Migratory Bird Treaty Act (MBTA) and given federal protection. Depredation permits can be obtained through the U.S. Fish and Wildlife Service. In addition, individual states may require their own permits for legal take of these bird species.

Protocol for Monitoring Fish Communities in Small Streams in the Heartland Inventory and Monitoring Network. National Park Service, aprile 2021. http://dx.doi.org/10.36967/nrr-2284726.

Testo completo
Abstract (sommario):
Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. The federally endangered Topeka shiner (Notropis topeka) and other native fishes have declined in population size due to habitat degradation and fragmentation in Midwest streams. By protecting portions of streams on publicly owned lands, national parks may offer refuges for threatened or endangered species and species of conservation concern, as well as other native species. This protocol describes the background, history, justification, methodology, data analysis and data management for long-term fish community monitoring of wadeable streams within nine HTLN parks: Effigy Mounds National Monument (EFMO), George Washington Carver National Monument (GWCA), Herbert Hoover National Historic Site (HEHO), Homestead National Monument of America (HOME), Hot Springs National Park (HOSP), Pea Ridge National Military Park (PERI), Pipestone National Monument (PIPE), Tallgrass Prairie National Preserve (TAPR), and Wilson's Creek national Battlefield (WICR). The objectives of this protocol are to determine the status and long-term trends in fish richness, diversity, abundance, and community composition in small wadeable streams within these nine parks and correlate the long-term community data to overall water quality and habitat condition (DeBacker et al. 2005).

There is a long history of fish and wildlife management associated with Upper Mississippi River navigation dams owned and operated by the US Army Corps of Engineers (USACE). Many operational changes have been made to improve aquatic habitat, with recent emphasis on pool-scale drawdowns to enhance wetland benefits without affecting navigation or other uses. This special report describes projects successfully incorporating Engineering With Nature® principles in a review of the physical setting and historical fish and wildlife habitat management efforts using Upper Mississippi River System navigation dams. We reviewed 80 years of adaptation and lessons learned about how to integrate navigation operations and wildlife management. Several experiments have revealed the capacity to produce thousands of hectares of emergent and submersed aquatic plants, restoring much-needed riparian habitat for a variety of aquatic, wetland, and avian species.

Testo completo
Abstract (sommario):
Voyageurs National Park (VNP) is a water-based park that includes part or all of four large lakes and twenty-six smaller lakes commonly referred to as “interior lakes”. The 26 interior lakes of VNP are important aquatic resources with differing size and depth, water chemistry, trophic status, fish communities, and visitor use. Despite the remote location of these lakes, they have been impacted by multiple stressors, including contaminants and non-native species. This assessment provides key information in support of a science-based management plan for these lakes. The objectives of this assessment were to: 1) assess the status of each of the interior lakes and categorically rank the lakes from least to most impacted; 2) use the results to make specific science-based management and restoration recommendations for the most impacted lakes; and 3) make general recommendations that may be useful in managing all of Voyageurs National Park’s interior lakes. When all factors considered in this analysis (water quality, fish mercury concentrations, and fish community characteristics) were combined and assessed, thirteen lakes were classified as most impacted, nine as moderately impacted, and three as least impacted. Although nearly half of the lakes were classified as most impacted in this assessment, many of these lakes are in excellent condition compared to other lakes in the region. The factor-by-factor impact status of the lakes was considered to help describe the condition of the lakes and the potential for restoration. No local management options were identified to mitigate the mercury contamination in these lakes as research has shown the sources of the contamination to arrive from regional and global sources. Similarly, no management actions were identified to reduce nutrient concentrations in the lakes ranked most impacted for nutrient conditions as these are remote lakes with minimal or no development within their watersheds, and it was also noted that paleolimnological studies have shown that the nutrient status of the interior lakes was relatively unchanged from pre-European settlement conditions. Finally, for the lakes in which presumed introduced fish species are present, piscicides were considered as a potential management action. Piscicides were not recommended as a strategy to eradicate introduced fish species as it was determined that genetic conservation of the populations of native fish species still present in these lakes was more valuable than eradicating the introduced species.
