The effect of a recirculation aquaculture system on the reproductive performance of female mud crabs (Scylla serrata)

One of the problems in a mud crab hatchery is the low reproductive performance of the broodstock, even when the selection process has been carried out properly. Improving water quality with an aquaculture recirculation system (RAS) is expected to improve the reproductive performance of broodstock and to obtain descendants with high quality. The purpose of this study was to determine the effect of RAS on the reproductive performance of female mud crabs (Scylla serrata). The study was conducted by comparing two treatments, namely RAS and conventional systems (CS). The results of data analysis using Student's t-test showed significant differences (p0.05). The RAS system with a biofilter can maintain and improve the water quality of the broodstock culture environment, so that it can optimize and improve the reproductive performance of female mud crabs S. serrata.
