Effects of different feeds on the growth and survival rate of Marphysa sanguinea larvae for 23 days rearing

Abstract

The aim of this study was to investigate the effects of different diets on the growth and survival rate of Marphysa sanguinea larvae. Experimental treatments were set up with 6 types of food, namely Spirulina, biofloc (shrimp farm), biofloc (center), Diatom, Frippak (150), Diet (100-200nm). The results showed that the survival rate in all experiments were 100% after 7 days rearing. There were significant differences on the  growth and survival rate of larvae after 23 days rearing. The highest survival rate (90%) was found at experiment with Biofloc feed, the best growth rate was recorded for M.sanguinea larvae to be fed with diet.
