EXST7015 Daily Design 18 Survival and growth of pink shrimp ( Farfantepenaeus paulensis ) post-larvae (PL) were examined at different salinities. This study was conducted at the Marine Aquaculture Station of the Fundação Universidade Federal do Rio Grande in Brazil. Post larvae (PL) of Farfantepenaeus paulensis were reared at 22–25°C, 30‰ salinity, and natural photoperiod. Fifteen-day-old PL, reared at 30‰ salinity, were acclimated to 2, 5, 10, 20, and 30‰ over 5 days by daily reductions of 6, 5, 4, and 2‰ salinity, respectively. Post larvae kept at 30‰ salinity were used as control. After the salinity acclimation period, PL shrimp were raised in each of the salinities over 6 wk by stocking 80 PL shrimp in a 100-L plastic tank. Shrimp were fed ad libitum twice a day with a commercial diet. At the end of the experiment (week 6), all living shrimp were weighed (wet and dry weights) and measured (cephalotorax length was measured using a stereoscopic microscope) . Survival and
