Use of fermented kitchen waste in rearing Penaeus monodon larvae
MetadataShow full item record
Fermented vegetable and kitchen wastes are available as feeds for not only zoea but also mysis and up to certain points in the postlarval stages of sugpo, Penaeus monodon. It is recommended that the hatchery use fermented wastes as larval feed for P. monodon when diatoms or brine shrimp nauplii are lacking or in short supply. Among three stages namely, zoea, mysis and postlarva, the survival rate during postlarva particularly after P4 was quite low. The problems encountered are as follows: (a) how to prevent fermented particles from lumping, (b) how to prevent them from easily sinking to the bottom, and, (c) how to prevent bacteria and fungi, particularly Lagenidium sp blooming.
