PENGARUH PEMBERIAN IKAN RINUAK SEBAGAI PAKAN ALTERNATIF TERHADAP KELANGSUNGAN HIDUP DAN PERTUMBUHAN LARVA IKAN PATIN (Pangasius hypophthalmus, Sauvage)

Abstract

This study aims to determine the effect of rinuak raw fish and steamed fish rinuak on the survival and growth of larval catfish ( Pangasius hypophthalmus Sauvage ) . This study was conducted for 21 days from the date that is 9 to January 30, 2014 in Freshwater Aquaculture Development Unit Rays Farm Bawal , Lubuk cone . Test fish is catfish larvae aged 8 days to 20 fish stocking density / liter and maintained in a transparent plastic bucket as many as 12 pieces . As a control diet in this study is the silk worms , while the test is a kind of feed raw fish and fish rinuak rinuak steamed . Feeding is done adlibitum and frequency of feeding 3 times a day . Observations were made every day on the mortality of larvae and accompanied by penyifonan daily , while the length of the measurement samples on the growth done every 7 days and growth of the weight at the end of the study . The experiment was conducted with 3 treatments 4 replications . The treatments include treatment A , silk worms , Treatment B , Dough rinuak raw fish and Treatment C , Batter rinuak steamed fish

 Analysis of variance of the data showed that larval survival value hit F > F tab , the mean survival was significantly different between treatments , analysis of absolute length growth of catfish larvae also showed the value of the hit F > F tab , which means significantly different between treatments , whereas analysis shows that the growth rate of the weight of the hit F > F tab , also significantly different between treatments . From this research, the highest yield was obtained on treatment A , with an average survival of 92.75 % , the growth of larvae absolute length of 16.3 mm and a weight of 93.5 % growth rate
