The condition of the grouper-snapper fish stock in the waters of Sangihe Group of Islands Regency, North Sulawesi Province, Indonesia

Abstract

This study aims to describe the grouper-snapper fish resource condition in the waters of the Sangihe group of islands. Due to ecologically and economically important coral and demersal fisheries, particularly for small-scaled fishermen, the study is expected to be able to contribute to responsible fisheries management for the prosperity and the development of the local community. Data collection was done in fish landing center using sampling method for 7–15 days a month. Individual length was recorded at the landing base. The parameters analyzed were catch per unit effort (CPUE) and length-based spawning potential ratio. Results identified 42 species of snappers and 52 species of groupers landed in the landing base with 12 dominant species. The CPUE analysis showed a declining trend. The fish stock condition analysis indicated that there were 3 species of over exploited status, 6 species fully exploited and 3 species under exploited in the period of 2019–2021, then 4 species of under-exploited status, 4 species of fully-exploited, and 4 species of over-exploited status in the period of 2022–2023.
