| Abstract | ||
| The round scad (Decapterus russelli) is a commercially valuable fish species in the Sunda Strait, requiring sustainable management to prevent overexploitation. This study examined its reproductive biology, including first gonadal maturation size, gonadal maturation index, fecundity, and spawning patterns, to support conservation efforts. Findings indicate that female round scad reach gonadal maturity at 187mm, while males mature at 19mm. The species follows a partial spawning pattern, with peak spawning activity observed in May and July. The fecundity of round scad varies significantly, ranging from 1,774 to 196,031 eggs, influenced by body weight. The gonadal somatic index (GSI) fluctuates, with females exhibiting higher values than males, peaking in May. Sustainable management strategies include implementing a minimum catch size of 187mm, adjusting fishing net mesh sizes to 1.4 inches, and enforcing seasonal closures during peak spawning months. Effective fisheries management requires collaboration between local authorities, fisheries officers, and fishing communities. By adopting science-based conservation measures, the long-term sustainability of round scad resources in the Sunda Strait can be ensured. | ||
