Both poly- and perfluoroalkylated substances (PFASs) and mercury (Hg) are persistent bioaccumulative, and toxic substances (PBTs) of great concern due to their health effects on humans.  These pollutants are ubiquitously occurring in the global aquatic environment and dietary intake of fish is the major exposure pathway for humans. PFASs and Hg are widely studied in the temperate zones, but little is known from the tropical aquatic systems in Africa. Lake Tana, Ethiopia, is of high ecological va...

Includes abstract. / Includes bibliographical references (leaves 101-108). / Parvalbumin, the fish major allergen, accounts for over 95% of clinical symptoms in allergic fish consumers. Importantly, this allergen displays lgE cross-reactivity thus allergic sufferers can exhibit clinical symptoms after the ingestion of non-sesitising fish species. In an occupational setting, fish products have also been shown to cause allergic disease in fish-processing factory workers. Whether parvalbumin is a ...

Biologists have traditionally studied adverse health effects of contaminants on wildlife, whereas public health researchers have independently studied effects of the same chemicals on humans. This siloed approach limits maximal progress towards understanding and managing pollution if relevant findings are not translated between fields. A new threat to human health, and potentially ecological health, is metabolic disruption. Metabolism disrupting chemicals (MDCs) are environmental chemicals that ...

Production rates of seven species of fish, along with food-web interactions, were determined for one year in a pond. Production of fish in the pond amounted to 208.9 q/m2/yr. Over 95% of the production occurred in the summer, with Y of Y fish contributing 83.8%. There were two food-web interactions observed in Y of Y fishes: crappie vs. bass and bullhead vs. sunfish. When Y of Y fish shifted to benthic diets in the spring, the small biomass of benthos available could not sustain the larger biom...

碩士 / 國立高雄海洋科技大學 / 水產食品科學研究所 / 103 / Seafood tends to perish quickly and has a shorter shelf life than other meat products. Low temperature (-20°C) frozen is the most commonly used method to preserve seafood. However, ice crystals are easily formed during frozen and deteriorate the sensory characteristics. Thus, a simple method adding salt into water to reduce the freezing temperature and formation of ice crystals was invented. In this research, fish was placed into a plastic bag containing the 1...

Fish and shellfish are important sources of protein for the world population. Nearly 50 percent of fish and shellfish products originate from aquaculture, and the rest comes from traditional fishing. The marine stocks are under threat from unsustainable fishing practices. Together with fishing, aquaculture constitutes extra stress on the marine stocks and ecosystems. Aquaculture also causes other environmental side effects. International trade rules do not sufficiently take care of the ecologica...

Baited remote underwater stereo-video systems (stereo-BRUVs) were developed to determine fish abundance and size structure in a more unbiased, and relatively non-invasive manner across a broader range of depths and habitats than conventional sampling methods achieve. These characteristics make stereo-BRUVs particularly useful for research inside marine protected areas (MPAs) where researchers are required to minimize disturbance to the protected environment. Although stereo-BRUVs have been widel...

Magister Artium (Development Studies) - MA(DVS) / This thesis examines how recent South African government fisheries policies have affected the livelihoods and food security of small-scale fishers, using the Kalk Bay fishing community in Cape Town, South Africa, as a case study. Fish has for generations provided food security for the fishers of Kalk Bay and their families. This food security has been both through catching fish for direct consumption and selling fish for income. Fish is an excell...

Fisheries in crisis.... this has been a threat often faced in recent times by inland and marine fisheries. This study assessed the nature and quantity of native and other fish species consumption by Winnipeg residents to isolate not only consumption and purchase patterns, but also factors which may influence fish consumption. Data was collected by a probability sampling of Winnipeg households using a telephone survey. A questionnaire pertained to estimates of consumption and queried attitudes a...

Traditionally, marine fish meal (FM) and fish oil (FO) have been the major feed ingredients used as protein and lipid sources in the formulation of aquaculture feeds. However, these commodities are limited by their availability, high cost as well as negatively impacting the sustainability of wild fish stocks. Thus, finding alternatives sources to replace or reduce the use of FM and FO in aquafeeds is critical. The primary goal of this research was to determine the effects incorporating algal mea...

The Hox gene complement of zebrafish, medaka, and fugu differs from that of other gnathostome vertebrates. These fishes have seven to eight Hox clusters compared to the four Hox clusters described in sarcopterygians and shark. The clusters in different teleost lineages are orthologous, implying that a “fish-specific” Hox cluster duplication has occurred in the stem lineage leading to the most recent common ancestor of zebrafish and fugu. The timing of this event, however, is unknown. To address ...

Eine effektive Strategie zur Verhinderung der Ausbreitung von Infektionskrankheiten in der Aquakultur ist die Anwendung geeigneter Präventionsmaßnahmen, insbesondere die Impfung von Fischen. Das effektivste Impfverfahren stellt die individuelle Injektion des Impfstoffes dar. Bei Milliarden von Fischen jährlich ist dies jedoch sehr zeit- und kostenintensiv. Bei Säugetieren gilt Niederfrequenz-Sonophorese (LFS) als eine der fortschrittlichsten Technologien zur transdermalen Verabreichung von Wi...

Peressigsäure (PES) hat seit kurzem als Desinfektionsmittel in der Aquakultur Einzug gehalten. Gegenüber anderen konventionellen Desinfektionsmitteln besitzt es in niedrigsten Konzentrationen (ca. 1 mg l-1) eine hohe Effektivität. Des Weiteren hat die Anwendung von PES kaum einen negativen Einfluss auf die Umwelt. Die Applikation von PES in Aquakulturanlagen erfolgt direkt über das umgebende Haltungswasser. Dies geht mit einem direkten Kontakt der Mikroorganismen und der Fische mit dem Wirkstoff...

Due to the nutritional and health benefits, the consumption of fish as an important dietary protein source is increasing. However, the benefits are not always received by everyone. Fish is one of the eight major allergenic foods or food types and its prevalence in the United States was determined to be 0.4% of food-hypersensitive patients among the adult population. Approximately 1.1 million Americans suffer from various symptoms of fish allergy, and this number is increasing. Food manufacturers...

Management of fisheries resources is increasingly broadening its scope from single-species approaches to more holistic, ecosystem-based approaches that account for interactions of fish with a variety of ecological factors, such as predators, prey, and habitat. This ecosystem based fisheries management (EBFM) approach requires thorough biological and ecological understanding of systems pertaining to community structure, habitat suitability, and food web interactions. to strengthen the ecological ...

Five fishery independent data sets were used to investigate multispecies fish recruitment patterns in Chesapeake Bay (1966--1997). Despite differences in sampling gear, sampled habitat, collection methods, and sampling sites, the strongest multispecies recruitment patterns within each data set (revealed by separate principal components analyses) depict a negative relationship between recruitment of spring spawning anadromous fishes and fall-winter continental shelf spawning species. This pattern...

Fisheries sustainability is inherently linked to an understanding of the population-level effects of fishing. With an accurate characterization of historical fish and fishery dynamics, management agencies are more equipped to create regulations that sustain fishery resources over the long term. The overarching goal of this dissertation is to contribute to the advancement of fisheries stock assessment and promote resource sustainability. My research focused on highly migratory species (HMS), part...

Fish of the genus Xiphophorus belong to the oldest animal models in cancer research. The oncogene responsible for the generation of spontaneous aggressive melanoma encodes for a mutated epidermal growth factor receptor (Egfr) and is called xmrk for Xiphophorus melanoma receptor kinase. Xmrk constitutive activation mechanisms and subsequent signaling pathways have already been investigated and charaterized but it is still unknown if Egfr ligands may also play a role in Xmrk-driven melanoma format...

Abstract. The goal of this thesis is to analyse SONAR files produced by ARIS and DIDSON manufactured by Sound Metrics Co. which are ultrasonic, monostatic and multibeam echo-sounders. They are used to capture the behaviour of Atlantic salmon, which recently has been on the lists of endangered species. These SONARs can work in dark lighting conditions and provide high resolution images due to their high frequencies that ranges from 1.1 MHz to 1.8 MHz. The thesis goes through extracting data from ...

Parvalbumin is an abundant divalent cation binding protein of fast vertebrate skeletal muscle. Its proposed function is to sequester calcium after contraction, thus facilitating relaxation. Calcium and magnesium equilibrium dissociation constants and instantaneous rate constants of parvalbumins from two Antarctic teleosts (Gobionotothen gibberifrons and Chaenocephalus aceratus), two temperate zone teleosts (Cyprinus carpio and Micropterus salmoides), and one Arctic teleost (Boreogadus saida) wer...

Many herpetofaunal species are imperiled, and the causes of this are often a synergy of multiple factors. In wetlands specifically, two of the possible determinants of species occurrence and faunal community assemblage are fish presence and wetland permanence, which are not always correlated. Twenty wetlands were sampled in Jonathan Dickinson State Park, Florida, USA to observe how wetland herpetofaunal communities vary with fish, wetland permanence and other environmental factors. Herpeto...

Coral reefs worldwide are threatened by many environmental disturbances including harmful algal blooms (HABs) which have been increasing on Florida coasts over the past decade. Research has mainly focused on HAB identification, percent cover and other effects on the benthos but the relationship of HABs with upper trophic levels has received less attention. To study this relationship, a two-year investigation on a 10-m deep reef off of Hallandale Beach, was conducted. Stationary fish census coupl...
