REPRODUCTIVE PERFORMANCE OF INTRASPECIFIC HYBRIDS OF BLUE SWIMMING CRAB (Portunus pelagicus)

Abstract

High exploitation of the blue swimming crab (Portunus pelagicus) has significantly reduced its wild populations. The domestication process of this species has been started; however, its breeding program has not yet been successful. Therefore, this study aimed to examine the reproduction performance of intraspecific hybrids of blue swimming crab from Sorong (Papua) and Barru (South Sulawesi), Indonesia. P. pelagicus from Sorong has a bigger size, while the crab from Barru has a better reproduction performance, including fecundity and egg diameter. Hybridization was conducted between crabs from Sorong and Barru with different combinations of broodstock, namely: Barru female >
