Feed aside as one of many factors that can enhance the productivity of fish, additionally the largest component within the production price. Currently the worth of manufactured feed costly per kgnya. For the highest quality feed and has a price environment friendly is actually not easy.

A continuous availability of seeds with adequate amount and good high quality in fish farming is a essential requirement to extend the manufacturing. Sangkuriang catfish (Clarias gariepinus var.

Experimental technique is exploratively used in this research with qualitative descriptive evaluation. The amplification outcomes present the OPA-03 primer (5'-AGTCAGCCAC-3 ') is one of the best primer that visualizes fragments in all samples. The first offspring of the broodstock crosses of the identical strain had a kinship of 70%, the crosses between non-transgenic Mutiara with ciri ikan lele sangkuriang had 79% genetic similarity. The highest genetic similarity index (82%) was obtained from the primary progeny of crossing transgenic Mutiara with Sangkuriang. Israel has established fish farming with carp because the principal species. It is a successful agricultural practice as a end result of manufacturing is sweet and land in any other case useless is employed.

The total amount in the carp ponds was 522 kg/ha, and in the trout ponds it was 110,4 tons/ha.
