The effects of temperature and salinity on fatty acid synthetic activities in the oyster protozoan parasite, Perkinsus marinus, were tested in vitro at 10, 18 and 28 jC in a salinity of 28 psu and 14, 20 and 28 psu at a temperature of 28 jC using C sodium acetate as a substrate. Salinity treatments exhibited few treatment effects, but temperature significantly affected cell proliferation, fatty...
