2. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus
Abstract : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. READ MORE

3. Evaluation of Biomarker Responses in Fish : with Special Emphasis on Gill EROD Activity
Abstract : Many chemicals present in the aquatic environment can interfere with physiological functions in fish. Exposure to chemicals can be revealed by the use of biomarkers. Induction of 7-ethoxyresorufin O-deethylase (EROD) activity is a commonly used biomarker for exposure to CYP1A inducers such as dioxins and polyaromatic hyrdrocarbons. READ MORE

4. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish
Abstract : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

5. Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish
Abstract : Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. READ MORE
