Abstract
Mud crab, Scylla olivaceae is a fishery commodity with high economic value and nutritional value. Its marketing is not difficult because of the high demand for exports and seafood restaurants. This study aims to evaluate the effect of various doses of vitomolt and determine the best dose on meat quality and nutrient retention in mud crab fattening culture. This research was conducted at the Educational Farm, Hasanuddin University, Bojo Village, Mallusetasi District, Barru Regency, Indonesia. The test animals used were mud crabs, Scylla olivaceae totaling 240 individuals, 60 each per treatment. The treatments were tested with various doses of vitomolt in the feed, namely 0, 200, 400, 600 mg vitomolt/kg feed. Parameters observed were crab carcass measurement, body chemical composition, nutrient retention consisting of protein, fat and energy retention, and crab water quality. The results showed that by mixing various doses of vitomolt to the feed, the best dose in measuring mud crab carcass was 400 mg/kg feed, while the best dose for nutrient retention was the test results for protein retention and the best dose of energy was 600 mg/kg. The best fat retention is 400 mg/kg feed for mud crab, Scylla olivacea.
