| Abstract | ||
| The goldband snapper (Pristipomoides multidens), a deep-sea species of the family Lutjanidae, has high economic value, yet basic data for its resource management remain limited. This study aimed to describe the population and fishery characteristics of the goldband snapper in Tomini Bay, Indonesia. Data were daily collected from March to December 2017 at the Pagimana fish landing site. Population characteristics included a modal length of 33cm FL, negative allometric growth, a mean condition factor of 1.01, growth rate (K) of 0.31 year⁻¹, asymptotic length (L∞) of 58.75cm FL, natural mortality (M) of 0.7 year⁻¹, total mortality (Z) of 1.13 year⁻¹, and exploitation rate (E) of 0.38 year⁻¹. The sex ratio was 19.64% males to 80.36% females; peak recruitment occurred in April, and the spawning potential ratio (SPR) averaged 22.33%. Fishery characteristics showed that handline was the dominant fishing gear; fishing grounds were spatially restricted; peak fishing season occurred in April; average abundance index was 30.6kg/ trip; and the highest landings were in May. The goldband snapper contributed 24.5% of the Lutjanidae catch, with a first capture length (Lc) of 26.7cm FL. It is recommended to improve fishing gear selectivity and to establish production limits to ensure sustainable management of goldband snapper resources in Tomini Bay. | ||
