Palaemonid Shrimp, Macrobrachium Amazonicum: Effects of Salinity and Temperature on Survival

Progressive Fish-Culturist, 1979
Abstract Survival of larval Macrobrachium amazonicum was evaluated at salinities of 0.0, 2.5, 5.0, 7.5, 10.0, 12.5, and 15.0‰. The effects of acute cold shock and a gradual temperature decline (2.0°C/day) on larvae, postlarvae, and juveniles were also evaluated. Larvae metamorphosed to postlarvae at all salinities except 0.0‰; survival was 64% at 10.0‰
