| Abstract | ||
| The purpose of this study was to review the parameters of the population dynamics of the yellowstrip scad (Selaroides leptolepis) for consideration in sustainable management from October 2020 to March 2021. Yellowstrip scad samples were collected using purse seine, gill net, and hand line fishing gears and then analyzed for population parameters to meet the study objectives. The parameters of the yellowstrip scad population in Ternate Island waters were relatively stable, with a maximum length value of 33.49 cm, growth coefficient of 0.99 per year, fishing mortality of 0.42, natural mortality of 1.71, exploitation rate of 0.2, and SPR 4 of 2%, and a recruitment value of 1.9% Y/R and 56.8% B/R. Whereas, these findings indicate that increased fishing effort is required until the exploitation value reaches 0.4 for optimal and sustainable management. | ||
