Abstract

The effects of eyestalk ablation on maturation, moulting and spawning in Penaeus semisulcatus were investigated in this study. Twelve males and 12 eyestalk-ablated and 12 non-ablated, all individually marked females were stocked into a 12-ton maturation tank. All the ablated females moulted in 9.08±1.68 days and first spawning occurred 16.75±3.41 days following eyestalk ablation. While all the ablated females spawned, producing an average of 177.000 ±133.340 eggs, only three non-ablated females spawned, producing average of 23.216±16.957 eggs during a period of 45 days (P0.05). Average nauplii production per female was 81.574±55.126 for ablated and 13.397±11.535 for non-ablated ones (P
