Domestication of Marble Goby [Oxyeleotris Marmorata (Bleeker, 1852)] Indogenous Fish of Citarum River, Indonesia

Abstract

Research on domestication of Marble Goby [Oxyeleotris marmorata (Bleeker, 1852)] has been conducted from September 2014 until March 2015 at Research Station, Faculty of Fisheries and Marine Science, Padjadjaran University. The aim of the research is to find out optimum feed rate that produce highest growth. This research used experimental method, there are three treatments feeding living tilapia rates of 2%, 3% and 4%, respectively. Observed parameters are growth rate and water quality. The results showed that the growth rate with feeding rate of 2% to 4% of Marble Goby increase 0.52 g · d^–1 to 0.82 g · d^–1 at the second month. However, at the third month, its growth rate tends to decrease to be 0.32 g · d^–1 to 0.44 g · d^–1. Feeding up to 4% is not yet generating the optimum amount of feed to get fish growth maximum. The quality of water i.e temperature, pH and dissolve oxygen are still in optimum range. But the light penetration is below its optimum range.
