Article: Marine and Atmospheric Sciences: salinity tolerance of red snapper (lutjanus campechanus) eggs and larvae.(Brief Article)

Gulf Coast Research Laboratory (GCRL) cultures red snapper larvae at 30-35 ppt to match conditions in the wild. However, red snapper larvae require live zooplankton cultured in 5 ppt to 20 ppt. Live zooplankton may experience salinity shock when transferred into salinities differing by 10 ppt or more. Therefore, the purpose of this study was to determine if red snapper larvae can be cultured at lower salinities without compromising survival and growth to reduce stress on live zooplankton. Red snapper eggs, day-0, day-1, and day-2 post-hatch larvae were tested at four different salinities (5, 15, 25, and 30 ppt) in a small-scale experiment. Eggs and larvae were monitored ...
