THE EFFECT OF CHITOSAN EXTRACTED FROM LOBSTER SHELLS ON THE PALATABILITY OF LOBSTER ARTIFICIAL FEED

Abstract

Lobster production is influenced by the availability of feed with the right level of preference and nutrition, chitosan can be used to increase the palatability of lobster artificial feed.  This study aims to determine the effect of chitosan extracted from lobster exoskeletons on the palatability of lobster feed. This study used a completely randomized design (CRD) consisting of 5 treatments and 4 replications.  The treatment given was the concentration of chitosan, namely treatment one 0%, treatment two 0.6%, treatment three 0.7%, treatment four 0.8%, and finally treatment five 0.9%.  The results of the study showed that the highest palatability level was shown by treatment 1 (0.55181 gr), followed by treatment 5 (0.50967 gr), treatment 2 (0.50803 gr), treatment 3 (0.50342 gr), and finally treatment 4 (0.5061 gr). Chitosan rises significantly the palatability of lobster artificial feed.
