The invasive Indo-Pacific Lionfish Pterois volitans has been recognized as a severe threat to indigenous fish species on Caribbean reefs. Previous studies have identified an extensive variety of Caribbean fishes in the stomachs of lionfish, but few have tried to quantify the impact these invaders could have on endemic or threatened species. The threatened Labrid fish Halichoeres socialis has been identified as the primary component of lionfish diet in Belizean lagoonal reef systems. This study a...

This study aimed at using different types of food wastes as major sources of protein to replace the fish meal used in fish feeds to produce quality fish. The major objectives were to (1) investigate the variations of metalloid/metals, polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in the fish ponds (pond mud and water), and food wastes used as fish feeds; (2) analyze bioaccumulation and biomagnification of pollutants in the food chains; and (3) evaluate the potentia...

<p> Reservoirs throughout the country exhibit degraded shorelines and simplified littoral habitats because of aging. This study evaluated the establishment of agricultural plantings on reservoir mudflats and the effectiveness of supplemental brush pile structures in providing recruitment habitat for juvenile fish. The mudflats of Enid Reservoir, Mississippi were seeded during the winter drawdown in October of 2016 and 2017 with agricultural plantings. Monitoring of plantings found grasses perfor...

Recreational fishing is a very important leisure activity and one of the most important ways how humans influence freshwater habitats and wild fish populations. Both fish-eating predators and socio-economic trends play a major role in recreational fishing. This thesis found that the Eurasian otter feeds mainly of small (5-10 g) and very abundant fish species of low angling value. In this case, gudgeon Gobio gobio dominated in the otter diet. The overlap between catches of otters and anglers was ...

A lek-breeding cichlid fish Pseudocrenilabrus philander was studied experimentally. Females in choice-chamber experiments showed no active choice for male size and colour, or for other male attributes, but preferred males which courted most actively. In a laboratory lek, the significant determinants of the strongly skewed mating success in males were territory size, side-shake and female chasing frequency. Together these three variables explained 79% of the variation in male mating success, with...

>Magister Scientiae - MSc / A novel 3-mercaptopropionic acid capped iridium selenide quantum dots based label free impedimetric immunosensor was successfully constructed. The 3-mercaptopropionic acid capped iridium selenide quantum dots synthesized were studied using HRTEM, revealing the formation of very small sizes, of about 3 nm. The optical Uv-Vis absorption wavelength of the quantum dots is blue-shifted, a phenomenon explained by the effective mass approximation (EMA) for semiconducting mat...

Thesis (M. Sc. (Zoology)) -- University of Limpopo, 2015 / The unprecedented expansion in human population and industry, since the industrial revolution in the late 1700s, has led to increased anthropogenic activities which have indisputably impacted freshwater ecosystems and biological communities therein, including fish. Although this has understandably been the focus, under natural aquatic conditions, no organism is only affected by pollution. Parasites have also been shown in a number of int...

The feeding interrelationships of three sparid fish was studied in the littoral zone during low tide at Clayton's Rocks in the Eastern Cape. The three species appeared in the study area only when between 9 and 10 mm long (SL), and remained resident until a length of approximately 120 fmm was reached. No sexually mature specimens occurred in the study area as large adults only use the intertidal zone for feeding purposes at high tide. From first recruitment into the littoral zone at 9 mm SL until...

Geelbek (Atractoscion aequidens) is an important fish species in South Africa's linefishery, a fishing sector defined by its fishing gear of rod and reel or handline. Distributed from Cape Point (34°21'S, 18°29'E) on the south west coast to Kosi Bay (26°51'S, 32°53'E) on the east coast, they are targeted throughout their range by the commercial linefishery, recreational anglers and small-scale fishers. The majority of geelbek are caught on the Agulhas Bank during austral summer. Due to current m...

Les lacs d'altitude sont soumis à des retombées atmosphériques de polluants organiques persistants (POP) issus pour la plupart des activités humaines malgré leur éloignement des sources d'émissions de ces composés. Si les mécanismes de transport atmosphérique de ces polluants jusqu'aux sites d'altitude sont désormais bien connus (« global distillation » ou « grasshopper effect »), on dispose en revanche de très peu d'informations quant à leur devenir dans ces écosystèmes montagnards.

Although mechanisms of calcium regulation in teleost fish are still poorly understood, there is indirect evidence that environmental Ca²⁺ may be involved. The gill, being the respiratory organ where blood comes into intimate contact with the external water, is likely to be a major site for ion transport. The objective of this project was to study the mechanisms of calcium transport in teleost fish, with special reference to branchial calcium-uptake, properties of a gill Ca²⁺-ATPase and the possi...

Two of the major dietary food sources of omega-3 fatty acids are flaxseed oil and fish oil; the former being a rich source of PUFA (e.g. α-linolenic acid (α-LA)), while the latter is a source of HUFA (e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)). In this study, palm oil, a commonly used vegetable oil that is widely available in Asian and African countries, was blended with flaxseed (omega 3-PUFA) and fish oil (menhaden oil) (omega-3 HUFA); respectively, to obtain blended...

The Skoenmakers River (located in the semi-arid Karoo region of the Eastern Cape) is being used as a transfer route for water transferred by the Orange-Fish-Sundays River Interbasin Transfer Scheme. The change in the hydrological regime of this once ephemeral stream to a much bigger perennial river led to dramatic changes to both the physical structure and riparian vegetation structure of the river system. These changes differ for each of the three river sections, the upper,middle and lower reac...

Human population growth is causing an increase in habitat transformation on a global scale, and this transformation is driven by changes in land-use practices. One consequence of habitat transformation is the negative effect it can have on mammal communities, especially carnivores. Carnivores are important components of ecosystems as they play an essential structuring role, but also often come into conflict with people. I studied the impact of land-use on mammalian diversity, the attitudes of la...

This Master’s research program was undertaken as part of the Hakai Ancient Landscapes Archaeology Project in Heiltsuk and Wuikinuxv Territories on the Central Pacific Coast of British Columbia (BC), Canada. The project tested the utility of applying vibracore technology to sample a shell midden site on Hecate Island on the BC Central Coast. This revealed that the earliest archaeological occupation began approximately 6,000 years ago, continuing into the 16th Century AD. Analysis using 21 radioca...

Les sites d'agrégation de ponte (AP) sont des zones où des poissons d'une même espèce se rassemblent pour frayer. En dépit de leur importance dans la reproduction de nombreuses espèces de poissons des récifs coralliens, bien peu de sites d'AP sont gérés. Le but de cette étude est d'améliorer la compréhension générale sur l'écologie des sites d'AP en vue de faciliter la gestion. L'étude, réalisée aux Seychelles, se concentre sur les individus regroupant sur les sites d'AP pour frayer et aussi sur...

Ray-finned fish from a diversity of distantly related lineages have remarkably large visual opsin repertoires. Starry flounder (Platichthys stellatus) development, morphology, life history, and behavior make this species especially suitable for experiments designed to determine why fish have so many opsins. Human and bird colour vision uses three and five opsins, respectively. Fish often have many more opsins. We sequenced an eye transcriptome to determine the starry flounder opsin repertoire, a...

Desertification is the diminution or destruction of the biological potential of land, and can lead ultimately to desert-like conditions. The vegetation of southern Africa is claimed to have altered over the past 100 years and much of the change is attributed to pastoral practice. In recent years however there has been much debate around the issue of the deterioration and loss of productivity of the natural rangelands, specifically those under communal management. It is one thing to claim that th...

Changes in the fish communities of the Breede and Mbashe estuaries were investigated in relation to the environmental variables that influence the fish assemblages in these systems. The Breede Estuary (34° 24’21.6”S, 20° 51’ 08.2”E) occurs within the warm-temperate/cool-temperate transition-zone, while the Mbashe Estuary (32o 14' 55.4"S, 28o 54' 03.7"E) falls within the subtropical/warm-temperate transition-zone along the South African coastline. The Breede Estuary was sampled (seine and gill ne...

With a declining population of roughly 3000-5000 individuals in Africa, African wild dogs (Lycaon pictus) are one of the most endangered carnivores in the world. As the global human population expands, it is becoming increasingly unlikely that large portions of land will be set aside for conservation, especially in developing countries. Thus, recent wild dog conservation efforts in South Africa have concentrated on establishing a managed metapopulation. A metapopulation is a group of geographica...

碩士 / 國立臺灣大學 / 機械工程學研究所 / 101 / Fast-start swimming is a very special and important type of locomotion of fish. Basically, fast-star motion can be classified into two types: C-type and S-type. It is generally thought that the C-type fast-start is adopted by fish for escape while the S-type fast-start is used in prey capture. Previous experimental data have shown that the maximum acceleration and maximum velocity of fish performing C-start are all significantly greater than that for S-type motion....

The Fish Creek-Vallecito section is the most stratigraphically complete and structurally intact Neogene exposure in the Salton Trough, and thus provides a useful reference section for regional stratigraphie revision and historical interpretation of the early Gulf of California and Colorado Delta. The section comprises a marine sequence (Imperial Formation) bracketed by nonmarine units (Split Mountain and Alverson Formations below, Palm Spring Formation and Canebrake Conglomerate above). Recognit...

<p> Two types of unusual concretions with similar contents but markedly different shapes and distributions were found in close stratigraphic proximity within the Whitmore Point Member of the Moenave Formation. Roughly cylindrical, elongate concretions were found in parallel and regularly spaced rows, and a layer of irregularly shaped and distributed fossiliferous concretions was discovered only a few centimeters above the cylindrical concretions. Both sets of concretions contain abundant hematit...

Androgens are correlated with reproductive behaviours including courtship and aggression. In the weakly electric fish, Apteronotus leptorhynchus, 11-ketotestosterone (11-KT) has been previously implicated in the regulation of electrocommunication behaviours that are believed to have roles in both aggression and courtship. In this thesis a method for performing repeated, non-invasive measurements of androgens released into the water was validated and applied for the first time in A. leptorhynchus...

Environmental and physical conditions are considered primary drivers of fish community assemblages. The anthropogenic alteration of aquatic ecosystems is implicated as a primary threat to fisheries worldwide. In riverine ecosystems, river-wide barriers may alter natural fluvial processes and hinder fish movement through the system. In this study, I use data collected from two successive years (2008 and 2009) of intensive quantitative electrofishing Casselman and Marcogliese (2008, 2009) performe...
