Growth and Gastrointestinal Conditions of Green Lobster (Panulirus Homarus) With Different Natural Feeding, Which are Raised in a Longline Submerged Cage System on the East Coast of Pangandaran Regency

Abstract

The purpose of this study was to test what type of natural feed provides growth and physiological conditions of the green lobster gut.  One important factor to support the development of aquaculture is appropriate feed to support growth. Efforts can be made to optimize the growth of sand lobsters through feeding that contains calcium and in natural feed consistently. This study consisted of 4 treatments of natural feed types rich in Calcium and Posfor, namely anchovies, reborn shrimp, gold snails, and barnacles.  The purpose of this study was to observe different types of natural feed that can increase lobster survival (SR), weight growth rate, intestinal histological features, hepatopancreas in green lobsters, and water quality at the study site. The highest survival rate in this study was found in the treatment of reborn shrimp and gold snails at 96%. In comparison, the highest growth rate parameter is the treatment of anchovy feed of 113.9 ± 30.7020. Furthermore, the highest intestinal histological condition is the treatment of anchovy feed, namely the area of villi of 1857,667  and the number of villi in the intestine in green lobster 1857,667.
