Rearing of post-larvae of Penaeus monodon in nursery pond-an experimental study

Abstract

In the present experiment, Poetlarvae of Penaeus monodon received from M/s Hindustan Lever Hatchery, Muttukkadu were reared in a nursery pond at porto Novo. In a span of one month, they were reared to the stockable size of 30 to 48 mm (average size 38 mm) from an initial size of 8 to 12 mm (average size 10 mm). Pond was suitably prepared after the application of cowdung. Coconut end palm leaves were fixed at the sides of the pond to avoid the direct heat of the sun and evoporation. Clam meat (Meretrix sp.) was used as the supplementary feed at 100% body weight- Hydrographical conditions of the pond waters in relation to length and weight (growth) have been discussed. About 98% recovery was achieved.
