Fish Stress

Andre Seale (Human Nutrition, Food and Animal Sciences) co-chaired a session on Environmental Physiology and Microbiology and gave a talk on “Endocrine Control of Growth and Osmoregulation in Fish: A Comparison Between Steady State and Dynamically Changing Salinity Regimes” at the 4th University of Hawai‘i–University of Tokyo Joint Symposium on Ocean, Coastal and Atmospheric Sciences hosted by SOEST UH Sea Grant. Fritzie Celino-Brady and Cody Petro-Sakuma, other members of Andre’s Laboratory of Fish Endocrinology and Environmental Physiology at HNFAS, presented, respectively, a talk, “Modulation of Reproductive and Growth Axes by Environmental Endocrine Disruptors,” and a poster, “Endocrine-Disrupting Effects of the Anthropogenic Pollutants Ethynylestradiol and Nonlyphenol on Growth and Reproduction in Mozambique Tilapia (Oreochromis mossambicus).” As a change from the highly sophisticated and technical language in these presentations, a research project by Andre and Fritzie on how environmental factors such as water temperature, salinity, and pollutants can place stress on tilapia was also chosen to be highlighted as one of Sea Grant’s podcasts: “Fish Stress Out, Too!” Here they explain their research in simple, easy-to-understand terms, showing how knowing more about this subject can help people in Hawai‘i, from producers of aquacultured tilapia to consumers to those who care about the environment.
