Abstract

This study provides a valuable information on the patterns of hybridization in producing Climbingperch’s fry which having a superior character to beneficially supports fish farming. The research wascarried out at Pokdakan Rawa Sejahtera Amuntai, South Kalimantan Province, Indonesia from June toDecember 2018. The hybridization procedures were applied to the selected broodstocks (total 135),which taken from three different types of habitats namely rain reservoirs, monotonous and tidalswamps. A complete random design was used as a research method with three treatments and ninerepetitions. A comprehensive investigation was done to provide the best performance among thetreatments. The results showed that the hybridized fish from monotonous swamp x tidal swamp wasthe most superior across the trials in term of fecundity (18,500 eggs), GSI (18.1%), hatching rate(89.5%), relative length growth (1,375%), relative weight growth (1,850%) and the percentage of birthfemale (84 %) with the lowest mortality rate (29%). For aquaculture practices, the use of the fryunisexual female would increase the fish growth 270% faster than the fry male.

Abstract

The swampy waters of Danau Bangkau, South Kalimantan are swampy waters that have an economic impact on the surrounding community. There is a need for research to know the productivity status of these waters from the abundance and diversity of fish. The research was carried out by dividing into 3 fish sampling stations determined by purposive sampling. The fish samples obtained were identified from families and species. The parameters observed and analyzed included the relative abundance of fish, diversity index, Evenness index, and Dominance Index. The results of the study were obtained from 1,108 individual fish and 28 species from 10 families. The results of the study show that the largest relative abundance is from the Cyprinidae family, which is 56.14% and this indicates that the waters are quite healthy because many fish are inhabited by herbivorous eating properties. The Diversity Index (H') obtained was 2.53 – 2.71, Evenness Index 0.52 – 0.55 and Dominance Index 0.37 – 0.44 which means that the waters are still healthy, with moderate productivity, but tend to be somewhat disturbed. The implication is that in the future there must be protection of the swampy waters of Danau Bangkau with strategies to restrict fishing and control sedimentation and domestic pollution.
