Penggunaan Distillers Dried Grains with Solubles (DDGS) dan hominy feed pada pakan ikan kerapu bebek cromileptes altivelis

Abstract

DDGS is a by-product in the production of bioethanol that is mainly derived from corn, while the hominy feed is a by-product of corn milling process on the production of corn flour for food. This study aims to examine the influence of the use of DDGS and hominy feed on the growth performance of humpback grouper Cromileptes altivelis. This research was conducted in June to October 2010 in floating net cage in Suak Panjang, Pahawang Island, Punduh Pidada sub-district, Pesawaran district, South Lampung and Fish Nutrition Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. This research used experimental methods Completely Randomized Design (CRD) with three treatments and two replicates respectively. The treatment in this study namely Diet A (diet without DDGS and hominy feed), Diet B (diet with DDGS and hominy feed 10%), and Diet C (diet with DDGS and hominy feed 19%). Fish weights 11.6-14.6 gram were reared in net cage (3x1x2)m3 at densities of 55-56 fish/m2. Fish were fed 3 times daily at satiation level. In ordered to keep fish in good condition net cage were wash weekly. The results showed that fish fed Diet B (DDGS and hominy feed 10%) have similar growth performance to those fish fed Diet A and higher when being compared to the rest. It is concluded that DDGS and hominy feed at the level of 10% can be used in the diet of humpback grouper.
