STUDY ON THE GROWTH ABILITY OF EEL (ANGUILLA BICOLOR McCLELLAND, 1844) COMMERCIAL CULTURED IN CEMENT TANKS WITH TWO TYPES OF FEED WERE EARTHWORMS AND FRESH TRASH FISH.

Abstract

Commercial cultured eel (Anguilla bicolor) was evaluated for its ability to grow at the juvenile eel stage of 100 g/ind was cultured in circulating cement tank provides enough oxygen with 2 types of feed earthworm and fresh trash fish. Stocking density of 20 ind/m³. Research results show that, after 10 months of cultured, the survival rate of ebony eels reached 91.25-96.38%, the average growth rates of each individual of weight was 80-105 g/ind/ month and length from 3.3-4.6 cm/ind/month, for fish at the larger size stage, the growth rates is faster. The feed conversion ratio FCR is 5.55-5.84.
