Abstract

ABSTRACT This research was conduct d on December 2019 until January 2020 in Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine, Riau University, Pekanbaru. The purpose of this research is to know the effect of feed replacement that are appropriate for growth and survival rate of Dokun larvae (Barbodes lateristriga). The method used in this research was an experimental method with Completely Randomized Design (CRD) one factor with five treatments and three replications, The treatment apllied in this study were C10A30 = Chlorella sp for 10 days + Artemia sp for 30 days. C20A20 = Chlorella sp. 20 days + Artemia sp 20 days.C10K30 = Chlorella sp 10 days+Dapnia sp 30 days. C20K20 = Chlorella sp 20 days + Dapnia sp 20 days. C10A10K10T10 = Chlorella sp 10 days + Artemia sp. 10 days + Daphnia sp 10 days + Tubifex sp 10 days. The results showed that the best treatment in P5 = (Chlorella sp 10 days + Artemia sp. 10 days + Daphnia sp 10 days + Tubifex sp 10 days) the absolute weight growth of 0,130 g, the absolute length growth of 1,12 cm, and a specific growth rate of 11, 60%, and survival rate was 66,7%, Water quality during the study, the temperature range was 26-27oC, pH range was between 6-7 and DO was 5.2-6.7. Keyword :Chlorella sp., Artemia sp., Daphnia sp., Tubifex sp., Growth, (Barbodes lateristriga)

Abstract

ABSTRACT The aim of this study was to evaluate the effect offeed types of fresh Tubifex worm, frozen Tubifex worm, mixed Tubifex (fresh and frozen) and frozen blood worms on the growth of survival of sheetfish larvae and to know the best type of feed between frozen Tubifex sp and frozen blood worms which can be used as an initial feed for sheetfish larvae other than fresh Tubifex sp reared in a recirculation system. This experiment used Completely Random Design (CRD) with 4 treatments and 3 replications, namely P1:  feeding the fresh Tubifex, P2: feeding the frozen Tubifex, P3: feeding the frozen blood worms, P4: Feeding the combination feed (fresh and frozen) with frozen blood worms. The results showed that there was an effect of feeding Tubifex sp and frozen blood worms on the growth and survival of sheetfish fish larvae (Ompok rhadinurus). The best treatment, P1with fresh Tubifex sp which produces an average growth of absolute weight of 5,14 grams, absolute length 8,76 cm, growth rate of 14,95% / day weight and 100% survival. Water quality parameter values are temperature of 270C - 280C, pH 5,6-5,7 and dissolved oxygen (DO) between 3,3-6,0 mg/l. Keywords : Tubifexsp, frozen blood worms, ikan selais (Ompok  rhadinurus).
