THE INFLUENCE OF COW'S SKIN FEED ON GROWTH AND SUSTAINABILITY OF SAND LOBSTER SEEDS (Panulirus homarus)

Abstract

This study aims to determine the effect of giving cow skin on growth and survival of lobster sand (Panulirus homarus). The method used in the study was an experimental method using a randomized block design (RCBD), with 5 treatments namely giving 100% trash fish, 75% trash fish + 25% cow skin, 50% trash fish + 50% cow skin, 25% fish trash + 75% cow leather and 100% cow leather repeated 3 times. observations carried out for 60 days. The parameters observed include absolute growth, specific growth rate, feed conversion ratio and survival rate. The results showed that absolute growth and the highest specific growth rate were found in rooting 3 (50% trash fish + 50% cow skin), which had a significantly different effect (P<0.05). Based on this study, to use feed with 50% trash fish + 50% cow leather and perform proximate tests on raw and boiled cow skin.
