Abstract

This research aims to determine the effect of long immersion of silk worms (Tubifex sp) in solution turmeric flour on the survival and growth of baung fish seeds (Hemibagrus nemurus). The method used is a randomized design Complete (CRD) with 5 treatments 3 replications, ie treatment P0 = without soaking, P1 = Soaking for 20 minutes, P2 = 25 minutes, P3 = 30 minutes and P4 35 minutes. The baung fish used is seeds that are 8 days old with an average weight of 0.09 g/head with a length of 0.70 cm/head. Seeds obtained from Saprizal's UPR in Padang Mutung village, Kampar district. From the results the study obtained the highest survival rate in the P4 treatment of 100% and lowest at P0 of 97.33%. Highest absolute weight gain found in the P4 treatment of 0.57 gr and the lowest was 0.37 gr. Growth The highest absolute length was in the P4 treatment of 3.46 cm and the lowest was 2.99 cm. The highest daily growth rate for the P4 treatment was 0.08% and the lowest 0.05%. The best feed conversion value was the P4 treatment of 0.46 gr. Parameter water quality, namely temperature 28-30oC, pH 6.13-7.69, dissolved oxygen 3.4-6.3 mg/L and Ammonia 0.88-4.22 mg/L.
