Thesis (MSc Food Sc )--Stellenbosch University, 2000. / ENGLISH ABSTRACT: Fermented fish products are popular food products mainly consumed and produced in Southeast Asia. These products are not produced in South Africa, and those available to the public are imported. The main action during the production and fermentation of this sort of product, is that of proteolysis, either by the bacteria or enzymes naturally present in the fish. The prevalent microbes present in six fermented fish sam...

Shoaling behaviour arises when fish respond to the movements and positions of nearby neighbours. The dynamic patterns of shoaling fish has been studied by the Mathematical department in Uppsala University. In this project experimental data collected for groups with two sizes of fish are analysed. An existing model was modified to reproduce the dynamic patterns in the fish shoal, this was done by comparing visual and statistical properties from the simulations with experimental observations. By a...

Data from studies looking at the use of systemic vitamin D and omega-3 fatty acids independently in the treatment of psoriasis has shown that both these supplements have at least a modest effect when taken in above average doses. Recent advances in the understanding of the pathophysiology of psoriasis as well as the immunomodulatory and anti-inflammatory properties of these supplements suggest that they could have an additive effect in treating this life-long disease. The proposed study is a ran...

Meandering rivers provide fresh water and important aquatic ecosystem services, yet at the same time induce flood and erosion hazards. In the face of ongoing development pressure and changing climate, growing concern for meandering rivers has increased the demand to model accurately the flow and predict the sediment transport in a meandering river channel. Calibration and validation of these models based on comparable field-based data, as opposed to laboratory-scale experimental data, may decrea...

abstract: Fish farming is a fast growing industry, which, although necessary to feed an ever growing worldwide population, has its share of negative environmental consequences, including the release of drugs and other waste into the ocean, the use of fish caught from the ocean to feed farm raised fish, and the escape of farm raised fish into natural bodies of water. However, the raising of certain types of fish, such as tilapia, seems to be an environmentally better proposition than raising oth...

The purpose of this experiment is to determine if immature female white mice will react to the gonadotropic hormone from the anterior pituitary of several species of fish. If they can be shown to do so, a second purpose is to establish an assay unit for this fish gonadotropin in order that it may be used with predictable results in inducing extra-seasonal spawning for fresh-water conservation practices.

Bishop, Jack G.

The purpose of this research is, first, to determine by laboratory methods, that species specificity does not exist in closely allied taxonomic animals; second, to determine a unit of activity for the gonadotropic hormone. For this purpose a quantitative method for determining potency is necessary to ascertain the seasonal production of the gonadotropic factor in fish. A further aim in this investigation is to demonstrate that the diversity of the gonadotropic factor, in relation to phylogenetic...

Many factors affect membrane composition in ectotherms, including allometry, temperature, toxins such as PCB-153, and osmotic stress. This thesis seeks to describe the relationship between membrane composition, size, and phylogeny in twelve species of cypriniform fish; to describe interactions between the homeoviscous responses to temperature and to PCB-153 in goldfish and rainbow trout; and to describe the membrane response to hypoosmotic stress in goldfish. Commonalities in these patterns prov...

A clarified, nonheat coagulable fish medium derived from condensed fish solubles (B.C. Packers, Richmond, B.C.) was explored for its potential use as the major component of a fermentation medium for the production of proteolytic enzymes. The organism used was a pure strain of Sorangium. Factors affecting the bacterial metabolic activity and consequently the rate and extent of protease formation were studied. Statistically designed experiments showed that both calcium and glucose had a signifi...

Yup’ik fishers on the Nushagak River of Southwest Alaska harvest salmon for both subsistence and commercial purposes, however their cultural protocol and formal resource management principles are unrecognized by the State of Alaska. Drawing from two summers of ethnographic research and experience as an Alaska Department of Fish & Game (ADF&G) anthropologist, I examine one state regulation preventing drift gillnetting for subsistence purposes. The analysis reveals that the Alaska Department of ...

Problems associated with fuel preference, metabolic capacity and regulation were addressed using isolated mitochondria and enzyme analyses of cardiac and skeletal muscles of spiny dogfish (Squalus acanthias), common carp (Cyprinus carpio), skipjack tuna (Katsuwonus pelamis) and rainbow (Oncorhynchus my kiss). Chondrichthian muscle is unusual because it possesses no detectible activities of carnitine palmitoyl transferase (CPT), which is involved in transport of fatty acids into mitochondria, ye...

Effective exploration of the environment is a critical aspect of adaptive behaviour, enabling animals to identify food sources, potential mates, refuge locations, and other important resources. The particular strategies used during exploratory behaviours depend on a variety of factors including context, personality traits and natural ecology. Weakly electric fish rely specifically on a short-range electric sense to search and locate objects in their environment in low-light conditions. However,...

Involvement of the red blood cells of fish in CDs exchange was investigated by examination of the CO₂ transport properties of fish blood, of ion movements (HCO₃₋, CI⁻, H⁺) across the red cell membrane, and of erythrocyte carbonic anhydrase activity. Adrenergic modulation of erythrocyte function in vitro and the effects of catecholamines on branchial CO₂ exchange in vivo also were studied. Approximately 92% of the CO₂ content of venous blood of rainbow trout (Salma gairdneri) was HCO₃₋, which ...

Wave-type weakly electric fish emit a highly regular electric discharge using a specialized electric organ. This electric organ discharge (EOD) forms the basis for an electric sense used for navigation, prey detection and communication. The metabolic cost of the EOD is not fully understood, but recent research suggests that it constitutes a significant portion of the fish's energy budget. In the current study, manipulation of metabolic rate via exposure to hypoxia did not significantly alter EOD...

The distribution and transfer of ammonia between intracellular and extracellular compartments of fish and the external water environment was investigated. In vivo and in vitro experiments were performed on the freshwater rainbow trout (Salmo gairdneri) and the intact, seawater lemon sole (Parophrys vetulus). The distribution of ammonia and H⁺ ions were compared between red cells and plasma (in vivo and in vitro) taken from rainbow trout at rest and during hypercapnia. At rest (in vivo and in vi...

Water in three separate applications was allowed to percolate through columns of pots containing different types of soils to which fish proteinate had been added only in the top pot. The volume of water was sufficient to saturate all the soil and to give a small excess for analysis. Plants were subsequently grown in all pots and the increased growth in different pot levels was used as a measure of nitrogen retention. On the whole the fish proteinate was well retained, particularly in heavy soi...

A fish waste product from a vitamin oil extraction process was tested to ascertain its value as a fertilizer. In order to obtain an evaluation, comparisons were made with three other well known fertilizers. In both Lettuce and Carrot crops, under field conditions, the fish waste proved as good as dried blood and superior to sodium nitrate and ammonium sulphate. The chief faults of this fertilizer material are its fine texture and deliquescent nature. Until the physical properties of this protei...

Certain compounds having the "carbonyl enediol" structure ( Formula omitted) , and also sodium chloride, were studied for use in glazes for frozen whole dressed fish. Incorporation of these compounds caused, in general, formation of thicker, glazes on the fish than did water alone and the glazes so formed were relatively non-cracking. The cyclic compounds, reductinic acid (in concentration 0.6475% or 0.00568M), and 1-ascorbic acid (1.0% or 0.00568M), afforded satisfactory protection against ox...

With its myriad of relationships, my study considers the Laich-Kwil-Tach enlivened world in which multiple beings bring meaning and understanding to life. Through exploration of Laich-Kwil-Tach ontology I engage with the theoretical concepts of animism, historical ecology and political ecology, in what I call relational ecology. Here, I examine the divide between the relational world and what Western ontology considers a natural resource; fish. Through an analysis of ethnographic texts I work to...

The goals of this dissertation work were to assess the bioaccumulation potential of carbamazepine and amiodarone, two widely used ionizable pharmaceutical compounds that possess mid-range and high LogD values, respectively, and to evaluate alternative methods to assess chemical accumulation in bluntnose minnows, catfish, and tilapia. Results indicated that carbamazepine does not appreciably bioaccumulate in fish tissue with BCFk and BAF carbamazepine values < 10. Amiodarone, however, with a log ...

Ongoing climate change is predicted to increase water temperatures and export of terrestrial dissolved matter (TDOM) to aquatic ecosystems influencing ecosystem productivity, food web dynamics and production of top consumers. Ecosystem productivity is mainly determined by the rates of primary production (GPP) in turn controlled by nutrients, light availability and temperature, while temperature alone affect vital rates like consumption and metabolic rates and maintenance requirements of consumer...

Selenium (Se), an essential element, can bioaccumulate and become toxic. The main toxicity symptom in fish, teratogenicity, is mediated by oxidative stress; however, little is known about the effect of Se on the physiological stress response (PSR). The effects of Se on the PSR and oxidative stress parameters were investigated in rainbow trout, brook trout, and white suckers. The PSR was activated by acute and sub-chronic laboratory exposures to NaSeO3, but not exposure to environmental levels of...

Introduced predators can have strong negative effects on native prey populations; the severity of this impact can be greater than that of native predators and can change with multiple predator introductions. I examined relationships between native fish assemblages and five widely introduced piscivorous fishes: largemouth bass Micropterus salmoides, northern pike Esox lucius, rock bass Ambloplites rupestris, smallmouth bass Micropterus dolomieu and walleye Sander vitreus. Analysis of data from...

An almost unbroken fringing reef runs along the east coast of Africa, the lagoon inside the reef is the foundation of almost all artisanal fisheries. It is a low-tech fishery conducted by many people. Some areas can have up to 19 fishermen per square kilometer. High fishing pressures, coupled with declining fish stocks has led to changes in mean size and reproductive age of many exploited species. There is a vital and urgent need for scientifically based management systems, including the utiliza...

This thesis integrates physiological and evolutionary ecology to quantify effects of hypoxia (low oxygen) on the energetic and life-history traits of the mouth brooding African cichlid, Pseudocrenilabrus multicolor. A field survey of 10 populations in Uganda indicated that dissolved oxygen (DO) is a strong predictor of interdemic variation in life-history traits. Females from low-DO sites were characterized by smaller size at maturity, and more, smaller-sized offspring than females from high D...
