Effects Of 17Β Estradiol In The Metabolism And Morphology Of Bluegill Sunfish (Lepomis Macrochirus), Neeta Parajulee Karki
Effects Of 17Β Estradiol In The Metabolism And Morphology Of Bluegill Sunfish (Lepomis Macrochirus), Neeta Parajulee Karki
Masters Theses
Fish natural habitats are increasingly contaminated with various estrogenic compounds, including 17β estradiol (E2). This compound causes adverse effects on the reproductive system of male fish; however, the effects of E2 on other aspects of fish metabolism, morphology and histopathological changes in internal organs are not well known. The objective of this study is to evaluate the effects of E2 exposure on the basal and stressed metabolic rate, morphological changes in body shapes, and histological changes in the liver tissues of sunfish species. Fish were held individually in ten gallon tanks under two treatments of 40 and 80 ng/L and …

The Influence Of Environmental Ph And Bicarbonate Concentration On The Excretion Of Nitrogenous Waste Products In Two Species Of Freshwater Teleost, Paul D. Fabsits
Masters Theses
The catabolism of amino acids derived from dietary protein results in the production of ammonia and bicarbonate ion, waste products that an animal must eliminate. Often, animals excrete a nitrogenous waste product that is correlated with water availability: Freshwater fish, living where water is abundant, usually excrete ammonia while terrestrial animals excrete urea or uric acid. Recent studies report that fish inhabiting alkaline waters (pH 10) characterized by high bicarbonate concentrations do not excrete ammonia, instead synthesize urea, an energetically expensive process. The conversion to urea excretion by a normally ammonotelic animal is likely to be stimulated by a specific …
