Palatability and Growth of eel Anguilla marmorata with Attractant Squid Meal and Shrimp Meal

Abstract

. Eel is a commodity that high value around and favored international markets. The most dominant issues in eel farming is the initial phase separating larval stadia and Elver. This is because at the stadia is difficult eel adapt to artificial feed (pellets), resulting in eels have a low body weight and slow growth. Slow growth greatly affects the performance of the production of increased maintenance time and cost of production. By providing attractants expected to increase palatability so that growth can be improved. The study was conducted using a completely randomized design with treatments without feed attractants (K), feed with shrimp powder attractant rebon 2% (R), feed attractant flour with squid as much as 2% (C), as well as the feed attractants squid and small shrimp (CR) , each of which was repeated 3 times. Fish kept in aquariums measuring 100x50x40 cm3 with a recirculation system as much as 60 individuals per aquarium with an average weight of 3 g ± 0:50. Feed given 4 times a day, ie at 05.00, 11:00, 16:00 and 21:00 are at satiation (sekenyangnya). Fish maintained for 45 days with sampling every 15 days. The results showed the amount of feed intake ranged from 101.49 g to 159.66 g, average daily growth rate ranged from 0.64% to 0.92%, feed efficiency ranged from 64.06% to 76.77%, and the survival rate ranged from 91.82% to 99.44%. Treatment gives the best effect on the amount of feed intake, daily growth rate and feed efficiency were treated with 2% squid meal attractant.
