Technology Engineering of Aquaculture Snakeheads [Channa Striatus (Bloch, 1793)] Using Cross Breeding from Different Waters for Determining the Genetic Variation of Superior Seeds

The objective of this research was to investigate the superior seed for snakeheads was result on the cross-breeding parent of snakeheads from different waters in Central Java. The material used snakeheads size 700 g ± 0.05 g (female and male) from different water in Central Java. Methods design completely randomized four treatments and three replications, the study in the first place from February 2015 to November 2015. Seed snakeheads caught from waters Rawa pening is crossbreeding caught from waters Segoro anakan (A), then is crossbreeding parent snakeheads from Gajah Mungkur waters (B), crossbreeding parent snakeheads from Rembang rivers (C) and crossbreeding from the parent snakeheads from Ujung Pangkah waters (D), superior seed treatment results from the production was given by pellet 5% / biomass / day. Study to produce snakeheads the size of consumption with the result of rapid growth, moderate and slow proceed anyway analysis of genetic variation genetic code, heterozygote, polymorphism snakeheads consumption size super. The results showed that of the maintenance of improved seed of cross-breeding waters of the Swamp Dizziness cork mated with parent fish caught from Ujung Pangkah (D), which is the highest result (165 337 mg) and lowest from waters Segoro anakan A (141.5 mg). Next polimorpisame analysis results using a micro-satellite to fish yielding seeds snakeheads on various treatment caught from waters Rawa pening be mated with parent from the waters Segoro anakan of snakeheads (A, band 1,2), the parent snakeheads Gajah Mungkur (B, band 3.4).
