Many fish live in variable environments, meaning they must constantly adapt to changes in water salinity, temperature and chemical content (i.e., pollutants). How a fish responds\u2014in order to keep surviving, growing and reproducing\u2014is of deep interest for scientists and commercial aquaculture producers who rely on controlled environments.<\/p>\n

Ongoing work in the University of Hawaiʻi<\/span> at M\u0101noa College of Tropical Agriculture and Human Resources<\/a> (CTAHR<\/abbr>) may provide some clues.<\/p>\n

CTAHR<\/abbr> investigators are doing research on three fronts, helping to better understand: <\/p>\n

    \n
  1. How fish hormones mediate the impact of a rise in temperature.<\/li>\n
  2. How the actions of these hormones are affected by age.<\/li>\n
  3. How chemicals and pollutants released in the environment can interfere with fish growth and reproduction.<\/li>\n<\/ol>\n

    “Our NSF<\/abbr>-, NIH<\/abbr>– and NOAA<\/abbr>-funded projects are targeted to better understand how specialized cells can sense the environment, respond to environmental change, and regulate functions essential for survival, such as salt-and-water balance, as well as functions essential for animal production, such as growth and reproduction,” said principal investigator Andre Seale<\/strong> of the Laboratory of Fish Endocrinology and Environmental Physiology, part of CTAHR<\/abbr>\u2019s Department of Human Nutrition, Food and Animal Sciences<\/a> (HNFAS<\/abbr>).<\/p>\n
