Judul: The Effectivity of Fish Meal Reduction at Different Levels of Protein in The Diets on The Growth Performance of Clarias sp.
Abstrak: This study was conducted to evaluate the effect of fish meal reduction at different levels of protein in diet Clarias sp. Six diets were used, diets A, B, C, D, E and F contain 32%, 30% and 28% protein with two level use of fish meal, 5% and 7%. Completely randomized design with 6 treatments and 3 replicates was used in this experiment. catfish with an average body weight of ± 21 g were kept in net with size of 1 x 1 x 1 m placed in ponds of 5 x 6 x 1 m, with density 100 fish each net. Fish overe fed on tested diets at satiation for 60 days of culture period. The results showed that regardless of fish meal content in the diet, fish fed on the diets contained 32% and 30% of protein had higher daily growth rate and feed efficiency of protein than that fed 28% protein diet. Feed consumption and survival rate were relatively similar among all treatments. Based on this research indicates that fish diet contain of 30% protein and 5% fish meal still able to support growth of catfish.

Judul: Efektivitas Penambahan Mannan Oligosakarida dan Vitamin C sebagai Feed Additive terhadap Kinerja Pertumbuhan ikan lele (Clarias sp.)
Abstrak: This study aimed to test of addition mannan oligosakarida (MOS) and vitamin C as feed additive on growth performance of Catfish (Clarias sp.). The feed used in this study is comercial feed with 39.4% protein dry weight content with the addition of feed additive is 3.6 g/kg. A total of 15,000 catfish (0.268 ± 0.26 gram) was reared for 20 days in tank (3 x 6x 0.5 m3) which has been equiped with aeration system. Fish feeding was conducted three times at 06.00, 16.00 and 24.00 (at satiation). The experimental design was a completely randomized design with 2 treatments and duplicate. The result showed that the amount of feed intake, protein retension and daily growth rate not significantly different (P>0,05). However, the biomass, feed conversion ratio (FCR) and survival rate in catfish with addition of feed additive in feed have significantly different (P<0,05). This result showed that the addition of MOS and vitamin C in catfish feed can decrease FCR and increase final biomass and survival rate (SR).
