Application of microcapsules food with different dosage to support the growth of fish cork seed (Channa Striata)

Abstract

Research occurred to manufacture microcapsule feed made by a local material like duck eggs and earthworms. These ingredients contain sufficient protein to support the growth of fish cork seed. The research was conducted for one month at the Laboratory of the Faculty of Fisheries, Pekalongan University. This study aims to determine the effect of microcapsules enriched with earthworms on snakehead fish seeds' growth. The use of earthworms with duck eggs is forming granules with sizes ranging from 20 µm - 120 µm, which are rounded as microcapsules feed. The research method used was experimental, using a completely randomized design (CRD) with treatments of 0 ml / l (A), 4 ml / l (B), 6 ml / l (C), 8 ml / l (D) and 10 ml. / l (E). The results showed that the microcapsule feed with different earthworm extract doses had a significant effect (F hit> F tab). The best treatment was at a dose of 10 ml (E) earthworms with a biomass weight of 0.46 grams. The supporting parameter is water quality in a temperature of 27-30oC and a pH of 7.4-7.9 to complete the cultivation of snakehead fish seeds.
