ABSTRACT

 

            This study was conducted to examine the effect formulations alternative feed on survival and growth of dumbo catfish (Clarian gariepinus Burchell).  Dumbo catfish  fry 4 day old  were reared for 12 days in density of 10 fish/liter and feed larvae with 4 treatments and 3 replications : Treatment A (Fresh Tubifex sp 100%), treatment B (Rinuak fish of dough marten 100%), treatment C (Rinuak fish of dough marten 80%, powder feed commersial larvae 15% and powdered milk 5%). Treatment D (Rinuak fish of dough marten 60%, powder feed commersial larvae 25%), powdered milk 15%). The daily of observed to mortality and during first 6 day of grouth larvae. The results of study showed that higher survival rate was obtained in treatment B (99.40%) and where are treatments of non significant.  Higher daily growth rate was obtained in treatment A (18,8%) and statistic on treatments is very significant.
