Abstract:

Quantitication of stress requires the use of a stress indicator that is easy to measure, and which can be readily interpreted in terms of the potential long-term effects to an organism. This study evaluates the suitability of metabolic rate as an indicator of the stress response in fish. By comparing the metabolic with the cortisol stress response, the most commonly used indicator of stress in fish, it was possible to assess the suitability of metabolic rate as a stress indicator. Changes in metabolic rate were used to predict the long-term effects of transport-related stressors. This study al

Abstract:

Exposure of an organism to a stressor results in a primary stress response. A part of this response involves the release of the catecholamines (CA), adrenaline (ADR) and noradrenaline (NADR), which exert their actions by binding to specific membrane binding sites or receptors termed adrenergic receptors or adrenoceptors (ARs). Continuous exposure to a hormone results in a decrease in the responsiveness of the cell. This process, termed desensitization may reduce the cell's responsiveness only to that hormone (homologous) or to another agonist (heterologous). Moreover, prolonged agonist exposur

Abstract:

The richness of nervous systems represented by extant fishes has not yet been determined; the brain morphology of many species, indeed, many groups, remain undescribed. For this reason we have examined esociform teleosts and focused on three goals: 1) to provide the first basic descriptions of the brains of two esociform teleosts, Esox masquinongy (muskellunge) and Esox lucius (northern pike); 2) to describe the development of E. masquinongy brains; and 3) to compare the neuronal features between E. masquinongy and E. lucius in light of the ontogenic pattern of E. masquinongy.

The role of host and non-host odours and derived chemicals in modifying copepodid behaviour was identified in laboratory bioassays.

The characteristics of the ion exchange mechanisms which regulate volume and pH in fish and amphibian erythrocytes were investigated and compared. Experiments were carried out under steady state conditions and also following adrenergic stimulation both in vivo and in vitro. Under steady state conditions, a decrease in extracellular pH caused an increase in the volume of rainbow trout erythrocytes, and a decrease in the intracellular pH. These pH-induced volume changes were mainly associated with movements of chloride across the chloride/bicarbonate exchange pathway. The sodium/proton exchange

Abstract:

This dissertation examines physiological stress responses of coastal elasmobranch fishes and investigates mechanisms that maintain oxygen delivery under stress. Elasmobranch fishes are, in general, understudied despite their susceptibility (due to K-selected life histories) to unsustainably high fishing mortality and the effects of climate change. Knowledge of physiological stress responses is, therefore, necessary to understand species-specific resilience and overall susceptibility to stressors. In Chapter II, I describe the hypoxia tolerances of clearnose skate (Rostaraja eglanteria), thorny

Abstract:

The notothenioid fishes, which dominate the upper shelf habitats of the Antarctic Continental Shelf, have evolved in a relatively thermally stable environment for at least 10-15 million years. With the upper lethal limits of these fishes around 4-6°C and the lower limits set by the freezing point of seawater, they are described as extreme stenotherms. As a result, it has been hypothesized that these fishes should exhibit marked responses to acute changes in temperature, but that acclimatory effects may be reduced with prolonged exposure to elevated temperatures is not likely to increase their

Pyruvate was oxidized at high rates in all cases, indicating good potential for aerobic carbohydrate metabolism. At 15°C, malate was an equally good substrate for heart mitochondria, while all substrates were oxidized at similar rates to pyruvate in muscle mitochondria. Maximal oxidation rates of heart mitoch

Abstract:

The cellular stress response (CSR) is one of the most highly conserved mechanisms among all organisms. Cellular stress can be defined as damage or the threat of damage to proteins, macromolecules and/or DNA. The response to damage can involve cell cycle regulation, protein chaperoning, DNA repair or, if macromolecular damage is too severe, apoptotic mechanisms can be initiated. This thesis details experiments that were designed to examine the cellular response to non-lethal environmental stressors at the protein level, using two fish species as study models.

Tesis por compendio de publicaciones<br>La luz y los patrones de alimentación influyeron sobre el comportamiento, fisiología y reloj molecular de dos peces teleósteos. Se clonaron dos criptocromos de lubina (cry1 y cry2), expresándose en todos los tejidos estudiados y mostrando ritmos diarios de expresión en cerebro, hígado y corazón (excepto cry2). La fase (día/noche) de alimentación a demanda en lubina afecta a los patrones diarios de actividad amilasa intestinal y expresión de period1 en tejidos periféricos (i.e. hígado), pero no en cerebro. Durante las inversiones estacionales de alimentac

Abstract:

The lucinid bivalve Codakia orbiculata, whose gills contain sulphur-oxidizing symbiotic bacteria, occurs in high densities (500/m2) in the rhizosphere of shallow-water Thalassia testudinum sediments in Bermuda. Both sulphide and thiosulphate stimulate aerobic respiration in the isolated bacterial symbionts of C. orbiculata. Sulphide and thiosulphate stimulate anaerobic ^^COa fixation in bacteria isolated from sulphur-starved bivalves. Interstitial water sulphide concentrations in the bivalves' habitat reach 300 pM, and sulphate-reduction rates are high, but thiosulphate concentrations are low

Abstract:

Over the last decade the development and use of nanomaterials (NMs) and nanoparticles (NPs) has increased at a great rate. As a result there is an ever increasing risk of exposing humans and wildlife to these potentially harmful materials. Titanium dioxide nanoparticles (TiO2 NPs) and carbon nanotubes (CNTs) are two of the most widely used NMs at present. Their potentially harmful effects on organisms and physicochemical properties have been investigated in a growing number of scientific studies. However understanding the level of risk they may pose is far from satisfactory. The present body o

Abstract:

During preliminary research on cobia (Rachycentron canadum, L.) it became increasingly clear that more in-depth information was required to provide enabling techniques for the cobia aquaculture industry to develop more rapidly. A unifying theme in many of the more important issues facing cobia aquaculture is nutrition. This led to nutritional investigations with larval and juvenile fish highlighting the impacts of dietary ingredients on animal performance. Indeed, nutrition can be viewed as a central lever of action through which many aspects of the physiology and the environmental (water) qua
