The goal of this project was to develop streamlined protocols that could be integrated into a standardized approach for vitrification of germplasm for all aquatic species. Vitrification (freezing by formation of glass rather than crystalline ice) is simple, fast, inexpensive, can be potentially used to preserve samples in the field, and offers new options for germplasm management especially appropriate for small fishes. Sperm were studied from freshwater fish (channel catfish Ictalurus punctatus...

Ecosystem-level changes have taken place in the Mediterranean Sea over the last decades due to both anthropogenic interferences and natural perturbations. Compared to the western Mediterranean Sea, influences of these factors especially on flora and fauna characteristics are much more dramatic and intense in the eastern part, particularly in the northeastern Levant Sea where the study area is located. In this study, life history traits of some core species (both native and immigrant) occupying t...

Estuarine habitats serve as important nurseries for many species of juvenile fishes and invertebrates. Due to concerns about declining fishery stocks and habitat degradation, it is critical that the value of different habitats be evaluated, so that areas that are most important can be prioritized for habitat conservation and restoration. This dissertation used Atlantic croaker (Micropogonias undulatus) as a model species to quantitatively examine patterns of early juvenile nursery habitat use, f...

This thesis explores the feasibility of using melanophore-based biosensors from Oreochromis niloticus. Melanophores are one type of pigmented cell of the scales and fins of fish that respond in a motile fashion to a diverse range of stimuli. Fish scales were employed as the first step in determining the utility of melanophores as biosensors. Responsiveness of melanophores in scales was quantitated with several bioactive agents. Experiments with depolarizing potassium ion, guanethidine, yohimbine...

Increasing awareness about the presence and ecological ramifications of toxic, persistent and bioaccumulative contaminants within the Great Lakes system spurred the implementation of numerous bans and emissions restrictions over the past few decades. Due to their high trophic status in food webs and the critical link they serve with human consumers, fish species have historically been monitored to assess the relative success of such remedial efforts within the region and to simultaneously ascert...

The Great Lakes has been impaired by elevated concentrations of contaminants, and different regulatory actions are taken to decrease theses concentrations. Recent research of Dr. Azim suggests a decline in mercury levels in the Lake Erie, and an increase in the Hg concentration in the fish communities. This research is a follow up study to examine whether the contaminant levels are indeed increasing. In the first chapter we evaluate the temporal trends of polychlorinated biphenyls (PCBs) in ...

The overall objective of the research conducted and described in this thesis was to develop an environmentally relevant bioassay to assess the effects of complex effluents on a sentinel fish species. A short-term fathead minnow (FHM) reproductive bioassay was utilized to assess the effects of industrial effluents on multiple levels of biological organization (sub-organismal to population endpoints). The FHM bioassay was tested in both lab and on-site investigations using an artificial stream sys...

Adequate levels of dissolved oxygen (DO) are essential to the health of most aquatic organisms. While diel fluctuations in DO concentration are a normal occurrence in aquatic ecosystems, anthropogenically-produced periods of prolonged hypoxia have the potential to cause changes in growth, reproduction and behaviour in animals. My thesis examined reproductive behaviour and physiology of fathead minnows (Pimephales promelas) following exposure to several concentrations of dissolved oxygen. Using a...

<p>It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters of temperature, pressure, particle size and solid/liquid ratio (S/L) being varied. The ranges adopted for the input parameters were: temperature of 30 &ordm / C or 90 &ordm / C / pressure of 1 Mpa or 4 Mpa / four particle sizes namely bulk ash, &gt / 150 &mu / m, &lt / 20 &m...

Aspects of the biology of common fish species in the Avon-Heathcote Estuary were investigated from two distinct types of sample site, during two sample periods between July 1996 and April 1997. The sites consisted of sites 1-6 (channel sites), which were sampled using a seine net, and estuarine fringe sites A-F, which were dip-net sampled. Although a relatively low diversity of fish species were captured, this was believed to be partly due to sampling methods and conditions. The species that wer...

Whole animal and in vitro experiments were used to compare and contrast the cardiovascular and, to a lesser extent, respiratory effects of three fish anaesthetics at approximately equipotent concentrations: 100 ppm MS222, six to ten ppm metomidate and 60 ppm Aqui-S. Heart rate, cardiac output, dorsal aortic pressure, stroke volume, haematocrit, PaO2 and plasma catecholamines were measured during five minutes of anaesthetic exposure with no other obvious stressors. Observed changes were due to bo...

In order to decrease the pollution of the marine environment from dumping fish waste and by-catch, alternative use for co-digestion with sludge in anaerobic condition was studied. The purpose of this project is to optimize the methane potential from adjustment of the proportion among mixed substrates. Ten groups of different proportions among fish waste, by-catch and sludge were conducted with AMPTS II instrument under mesophilic condition (37 ± 0.5 ºC), by means of the principle of BMP test. Th...

The conditions under which fish have a large impact on benthic invertebrate community structure in streams are poorly defined. To better understand the mechanisms by which fish affect lotic invertebrate community structure, a series of experiments were performed in a fishless and fish-bearing stream in the University of British Columbia Malcolm Knapp Research Forest in the Coast Mountains of British Columbia. The first experiment examined the effect of predation by prickly sculpin (Cottus ...

Dams and weirs are widely implicated in large-scale declines in both the range and abundance of aquatic fauna. Although many factors are involved, such declines are commonly attributed to the prevention or reduction of migration, reductions in available habitat, alteration of natural flow regimes and changes to physicochemical characteristics. In Australia, studies into the ecological effects of these impacts are limited, and have concentrated mainly on species of recreational and commercial imp...

Seagrass is an underwater flowering plant that thrives in clear, sheltered, coastal waters around the world. As well as providing habitat for the marine fauna, seagrass meadows play an important role in the processes and resources of near-shore ecosystems. Coastal degradation of seagrass is prevalent along the metropolitan beaches of Adelaide, a problem common to settled coastal areas around the world, and although evidence from the literature suggests that loss of seagrass beds adversely affect...

Weakly electric fish use of a self-generated electric field to probe their environment, this behaviour is known as electrolocation. This study investigated two aspects of electrolocation in two species of knifefish (Apteronotus leptorhynchus and Eigenmannia virescens). First, we characterized the ability to track moving objects and found that tracking performance did not differ among speeds tested in either species. Second, we characterized a motion-related cue for distance perception, similar t...

Saltmarsh loss is occurring at high rates in Louisiana (LA), but understanding the impacts that marsh degradation has had on historical abundance of estuarine nekton in Barataria Bay, LA is lacking. I first examined the differences between fishery independent and fishery dependent data as indices of relative abundance. Previous studies used landings data to evaluate the importance of marsh habitat (e.g. distance of marsh edge and area of intertidal marsh) to fisheries production, but for most sp...

Maintaining energy organismal homeostasis under changing physiological and environmental conditions is vital, and requires constant adjustments of the energy metabolism. Central to meeting energy demands is the regulation of mitochondrial oxidative capacity. When demands increase, animals can increase mitochondrial content/enzymes, known as mitochondrial biogenesis. Central to mammalian mitochondrial biogenesis is the transcriptional master regulator PPARγ (peroxisome proliferator-activated rece...

Polycyclic aromatic hydrocarbons (PAH) are common aquatic contaminants found at industrially contaminated sites. Alkylated PAH have been identified as a component of oil that is chronically toxic to the early life stages of fish. These compounds are important target analytes in Natural Resource Damage Assessment following oil spills, and often the focus of remedial activities. However, the mechanisms of PAH and alkyl-PAH toxicity are not well understood. The enzymatic metabolism of alkyl-PAH gen...

One of the greatest challenges to developing successful marketing strategies in the food sector is gaining a better understanding of the diversity of consumer needs (Onwezen et al., 2012). It is important to understand consumer perceptions of beef, pork, lamb, chicken, and fish regarding consumption levels, price, nutrition, animal handling, and animal welfare to help the industry educate and market to consumers, as well as understand perceived misconceptions. Moral and ethical beliefs, consisti...

Although mammals are the most commonly utilized laboratory animal, laboratory animal medicine continually seeks to replace them with animals of lower phylogenic classification. Fish are becoming increasingly important as investigators seek alternative animal models for research. Fish can provide an economical and feasible alternative to typical mammalian models; moreover, many fish, which have comparatively short life spans, can easily reproduce in the laboratory. One key area of animal health r...

The production of biodiesel from fish oil was carried out using enzymatic transesterification. The effects of the oil: alcohol molar ratio (1:1, 1:2, 1:3, 1:4 and 1:5), alcohol type (methanol and 2-butanol), reaction temperature (35, 40, 45 and 50ºC), reaction time (4, 8, 12 and 16 h) and solvent type (solvent and solvent-free) on the biodiesel conversion yield using Candida antarctica (Novozyme 435) and experimental enzyme (NS88001) were investigated. The biodiesel conversion yield increased wh...

Commercial harvest of fish stocks and their appropriate management requires an understanding of their population dynamics and of their ability to sustain exploitation. Here, some ecological and evolutionary consequences of excessive exploitation are examined. In Chapter 2 I evaluate the knowledge base and status of commercially exploited marine populations that undergo formal stock assessment. Despite a bias towards industrialised countries and stocks of commercial importance, I show the pervasi...
