Induced maturation and spawning of Penaeus indicuswithout eyestalk ablation
Year: 1986
Type: article
Abstract: Farm-grown Penaeus indiciis > 32.5 mm in carapace length ( > 150mm T.L. and 25 g wt.) were induced to mature and spawn in captivity by merelymaintains the pH of the maturation pool at 8.1-8.2. The regulation of the pHwas done by daily addition of adequate quantities of Na2C03 to the recirculatedseawater. 61.8% of the experimental prawns matured and spawned and 81%of the spawnings gave rise to normal healthy larvae. The average number of eggsobtained per female was 119,614 and the average hatching rate was 82.5%. Thistechnique of inducing maturation eliminates the stress of eye-stalk ablation onthe broodstock.
