Description |
Farm-grown Penaeus indiciis > 32.5 mm in carapace length ( > 150 mm T.L. and 25 g wt.) were induced to mature and spawn in captivity by merely maintains the pH of the maturation pool at 8.1-8.2. The regulation of the pH was done by daily addition of adequate quantities of Na2C03 to the recirculated seawater. 61.8% of the experimental prawns matured and spawned and 81% of the spawnings gave rise to normal healthy larvae. The average number of eggs obtained per female was 119,614 and the average hatching rate was 82.5%. This technique of inducing maturation eliminates the stress of eye-stalk ablation on the broodstock. |
