2. 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

5. Teleost reproduction: Aspects of Arctic char (Salvelinus alpinus) oocyte growth and maturation
Abstract : In all vertebrate species, reproduction is a hormonally controlled process, important for growth and maturation of gonads and germ cells. Production of functional germ cells is of outmost importance to secure the survival of a species. Fish comprises 50% of the known vertebrates and are found in aquatic habitats all over the world.
