| Abstract | ||
| The scallop Amusium pleuronectes is a highly economically and ecologically valuable bivalve species. This study examined biometric parameters, gonadal maturity stages (GMS), size at first gonadal maturity, and the gonadosomatic index (GSI) to evaluate their implications for broodstock management, hatchery seed production, and the broader development of sustainable scallop aquaculture in Indonesia. Sampling was conducted at Teluk Bone and Makassar Strait in January, May, July, September, and October 2021. Analyses included morphological and histological assessments of gonadal maturity and the determination of size at first gonadal maturity using the Spearman–Karber method. The results revealed significant differences in GMS, size at first gonadal maturity, and oocyte diameter between the two locations. In Teluk Bone, scallops exhibited greater variability in GMS, with the highest mean value recorded in September (25.99 ± 18.36%), whereas in Makassar Strait, GMS peaked in October (47.84 ± 35.61%). The size at first gonadal maturity was 52.69 mm in Teluk Bone and 45.77 mm in Makassar Strait. These findings indicate that environmental conditions in the two locations significantly influence the reproductive characteristics of A. pleuronectes. Teluk Bone, with more variable conditions, may provide a more favorable environment for reproduction and aquaculture potential than the Makassar Strait. This study provides critical insights for the sustainable management, aquaculture development, and conservation of A. pleuronectes populations in Indonesian waters. | ||
