Pemanfaatan Limbah Pendederan Ikan Lele (Clarias sp.) untuk Pendederan Ikan Nila (Oreochromis niloticus) dan Ikan Gurame (Osphronemus goramy Lac.)

Abstract

This research was aimed to study the utilization of catfish waste for tilapia and giant goramy in an integrated rearing system. In the research, waste from catfish rearing in cemented tank was utilitized for tilapia (NI) and giant goramy (GI) rearing in an earthen pond as integrated rearing. To compare (as a control) in another earthen pond, tilapia (NK) and giant goramy (GK) were reared and fed with artificial feed. Catfish, tilapia and giant goramy stocking density was 2000 fish/m3, 24 fish/m2, 10 fish/m2 respectively. Catfish, tilapia and giant goramy which used had been measured and each size were 0.94 g, 1.21 g, and 0.22 g. The research showed that The wastes produced by the catfish biomass of 644.67 g/m2 at initial and 1399.58 g/m2 at harvest could be used to grow tilapia and giant goramy. Until day 22 fish size remains the same at integrated rearing system and control, while at day 28, the growth rate of NI 1.92% lower than NK, whereas the GI lower 0.78% compared to GK. Survival rate of NI was 6.03% lower than NK, while GI was 0.51% lower than GK.
