Abstract:
This study provides a valuable information on the patterns of hybridization in producing Climbing perch’s fry which having a superior character to beneficially supports fish farming. The research was carried out at Pokdakan Rawa Sejahtera Amuntai, South Kalimantan Province, Indonesia from June to December 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 tidal swamps. A complete random design was used as a research method with three treatments and nine
repetitions. A comprehensive investigation was done to provide the best performance among the treatments. The results showed that the hybridized fish from monotonous swamp x tidal swamp was the 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 birth female (84 %) with the lowest mortality rate (29%). For aquaculture practices, the use of the fry unisexual female would increase the fish growth 270% faster than the fry male.
