Alternate Title

The Effect of Salinity on Spawning Frequency of Penaeus setiferus in Aquaria

Document Type



Penaeus setiferus were matured and spawned in a small 120L tank system in the absence of males. No significant differences in the number of shrimp that spawned or the time required to spawn were detected for shrimp held at salinities of 20, 25 or 30 ppt in either natural or artificial seawater. The earliest that spawning occurred was an average of 17 days past ablation and as late as 28 days past ablation. None of the shrimp held in artificial seawater at 20 and 25 ppt spawned in the same molt cycle in which they were ablated, while one third of the shrimp held in natural seawater did.
