Available in PDF, EPUB and Kindle. Book excerpt: Application of safety factors to water quality guidelines are often employed in the environmental management of waterborne metals. These factors extrapolate the available science into areas not reliably defined, such as: (1) & nbsp;acute-to-chronic toxicity, (2) & nbsp;laboratory-to-field exposures, and (3) & nbsp;model-to-resident species. Scientific advancements require modifications to the derivation process of water quality guidelines to minimize the arbitrary nature of safety factors. One advancement is the Biotic Ligand Model (BLM), which uniquely incorporates toxicology and physiology. This model, along with the mechanism of acute copper toxicity, forms the foundation of the thesis, with the main objective to reduce the uncertainty associated with the three areas in which safety factors are applied. The research employed laboratory experiments to understand the responses of freshwater fish to waterborne copper. This work was extended to a field situation with wild perch. In conclusion, the usual effect indicators of acute toxicity may be of limited value, in their current form, in evaluating chronic toxicity. The complexity of chronic toxicity reaches beyond the simple connections between acute effects and mortality. It now requires the translation of subtle physiological effects into an impact on growth, reproduction or fecundity, thereby affecting fish populations or aquatic food chains. The influence of water chemistry on copper bioavailability is one area most advanced in the last ten years, at least in part due to the development of the BLM. However, the influence of water constituents are likely to cause different effects on acute toxicity, rapid gill surface binding, metal uptake, and metal accumulation. Lastly, the laboratory and field studies using yellow perch, a species endemic to metal contaminated lakes, show that although the mechanism of toxicity may be identical to that of a model species (i.e., rainbow trout), the mechanism of tolerance can greatly alter the physiological indicators used to detect copper toxicity.

Melendez and published by . This book was released on 2019 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental temperature is a crucial environmental factor that influences many physiological functions in fishes. Rainbow trout (Oncorhynchus mykiss) are a native anadromous species that inhabit a variety of freshwater rivers and lakes and are widely distributed throughout the western portion of the United States. Resident rainbow trout populations occupy interior freshwater environments for the entirety of life. Interior bodies of water are most susceptible to changes in environmental temperatures. Therefore, resident rainbow trout are likely to be impacted by variable and rising temperatures, particularly during embryonic development. Understanding temperature effects during development is likely to provide insight into the overall thermal biology of a species and its persistence in a changing climate. To assess the effect of temperature on development of rainbow trout, we examined phenotypes of hatchery embryos reared in various incubation temperatures (5°C, 10°C, 15°C and 17.5°C). To identify the presence of embryonic developmental plasticity within developmental time points, embryos incubated in 5°C were exposed to either 10°C, 15°C or 17.5°C during gastrulation, organogenesis, system integration or growth windows and a 3-dimensional critical window model was applied. An increase in constant incubation temperature increased oxygen consumption rate (V̇O2), and decreased hatchling survival, mass, yolk size, body length and time to 50% hatch. Thermally shifting embryos into increased temperature during distinct windows of development also reduced survival at hatch, and this was most evident following exposure during organogenesis, which may signify the presence of a critical window for this trait. Likewise, thermally shifting embryos into increased temperature resulted in smaller hatchlings. Although there was an initial increase in V̇ O2 in response to temperature, experiencing thermal shifts during development had no persistent effect on V̇ O2 when measured at hatch at 5°C compared to 5°C constant embryos. Collectively, these results suggest that survival and morphological traits of rainbow trout embryos are most sensitive to increased temperature during organogenesis and system integration, but increased temperature does not appear to have a long-term effect on energy use. Environmental temperature plays a fundamental role in developing aquatic vertebrates. Thus, critical window studies such this performed across species will eventually allow for the identification of commonalities in plasticity between different species in response to variables such as temperature.

This book was released on 2016 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cu is a widely occurring contaminant in aquatic systems and is acutely toxic to fish. The current paradigm of copper's toxic mechanism of action in fish is believed to be through direct effects on several important functions of the teleost gill; therefore experiments were conducted to examine Cu effects on the osmoregulatory ability and swimming performance of juvenile rainbow trout (Oncorhynchus mykiss) in water of varying hardness. Fish were exposed to three Cu concentrations (0, 20 and 60 μg/L in hard water [100 mg/L CaCO3], and 0, 6 and 16 μg/L in soft water [6 mg/L CaCO3]), for 4, 8 and 16 d and then tested for their ability to osmoregulate and burst swim. Burst swimming speed (Uburst) was not different between control and Cu-exposed fish in either soft or hard water. Osmoregulatory ability following Cu exposure was examined through several biochemical measurements related to osmoregulation and a seawater challenge. Cu exposure did not elicit a change in any osmoregulatory-related measurement or result in mortalities during the seawater challenge. These results indicate that the current paradigm of Cu toxicity may not reflect the mechanism of sublethal Cu toxicity or that compensatory mechanisms are offsetting major physiological disturbances caused by Cu, at concentrations that are near those which typically cause mortality in salmonids.
