Pengkayaan Pakan Buatan Dengan Sumber Lemak Berbeda Terhadap Laju Sintasan Dan Pertumbuhan Benih Ikan Lelan (Osteochilus pleorotaenia)

Abstract

The purpose of this study was to determine the effect of enrichment levels of proximate and artificial feed with various source of fat come from animal and vegetable toward the survival and growth rate of fish pla seed with initial length of 5-6 cm. This research was conducted on February-April 2014 at the Integrated Laboratory in Faculty of Fisheries and Marine Science, Bung Hatta University, Padang. This study used the experimental method and used a completely randomized design (CRD) with 4 treatments and 3 replications. Treatment A = artificial feeding enriched with corn oil as much as 90 g / kg of feed, Treatment B = artificial feeding enriched with soybean oil as much as 90 g/kg of feed, Treatment C = artificial feeding enriched with cod liver oil as much as 90 g /kg of feed, Treatment D = artificial feed enriched with shark liver oil as much as 90 g /kg of feed. The results showed that the effect of artificial food enrichment with a fat source derived from animal and vegetable of the highest survival rates found on treatment D was 88.00 ± 6,92a%, and the lowest found on treatment A was 76.00 ± 10,58a%. The highest growth weight contained on treatment A was 3.35 ± 0,24a, while the lowest found on treatment D was 2.68 ± 0.11. the addition of length found on treatment A was 2.05 ± 2,96a , while the lowest treatment found on treatment D was 1.51 ± l, 91 '. The growth rate of the fastest-specific survival rate found on treatment A and B of 1.31 ± 0,09a%, and the lowest specific growth rate was found on treatment D was 1.11 ± 0,04b
