EFFECT OF DIFFERENT DIETS ON SURVIVAL OF GIANT PRAWN LARVAE (MACROBRACHIUM ROSENBERGII DE MAN)
P. MENASVETA,a S. PANICHAYAKUL,b P. PIYATIRATITIVORAKUL,a ,and S. PIYATIRATITIVORAKULaABSTRACT: Effect of live food and different compound diets on survival of giant prawn larvae was studied. Two sequential experiments were carried out. The first experiment dealt with five types of diets. Each diet was fed to a group of prawn larvae. The diets were Artemia nauplii and four types of compound diet comprising of fish protein, milk protein, and shrimp head extract. The second experiment consisted of alternated feeding, i.e. 12 h. compound diet and 12 h. Artemia nauplii. The compound diets of this experiment were the same as the first experiment. The larvae receiving a single diet (1st experiment) exhibited lower survival than those of the alternated feeding experiment. In regards to the alternated feeding, the diets comprising fish protein resulted in better larvae survival than the milk protein diets; although there was statistically no significant difference in survival. The diets containing shrimp head extract always gave better survival when compared with those without the shrimp head extract. a.
