Abstract

To determine the effects of salinity on adult and larval survival, egg deposition, egg hatching and metamorphosis, shrimp were held in the laboratory and exposed to treatment salinities ranging from O to 35 ppt. Tests on adult survival indicate a 96 hour LC-50 between 30 and 35 ppt. Longer term tests on adult survival showed high mortality in salinities greater than 15 ppt. Shrimp became ovigerous in salinities of O - 20 ppt with egg hatching and metamorphosis limited to O - 5 ppt. Starved- larvae hatched from field captured ovigerous females in O ppt were able to metamorphose in salinities of O through 30 ppt. Survival of these larvae was low after metamorphosis but was greatest for 5 and 10 ppt. These results support the hypothesis that brackish culture may be successful in salinities lower than 10 ppt. Further experimentation is necessary to determine whether culture will be successful in 10 ppt or higher.
