The use of substitute feeds in larval rearing of Penaeus monodon

Penaeus monodon larvae were stocked in 20-l conical plexiglass tanks in a water bath. Larvae were reared from protozoea to mysis I using feeds in combination with Tetraselmis sp. and Tetraselmis sp. alone. The feeds used were hard cooked ckicken egg yolk, beaten whole egg cooked in boiling water, cooked brown mussel, trash fish and soybean cake.Feeds were homogenized and pass through a 40 µm sieve prior to feeding. Three experimental runs were carried out. \nSurvival of the fed with various feeds had no significant differences at the mysis stage. However, faster groowth rate was significantly obtained in the larvae fed with hard cooked chicken egg yolk.
