Inventarisasi Jenis Ikan Elasmobranchii yang Ditemukan di Perairan Kota Sibolga Provinsi Sumatera Utara

Abstract

Elasmobranchii fish are an important fishery resource with high economic and ecological value. However, their biological characteristics of slow growth and low reproductive rates make this group vulnerable to overfishing. This study aimed to identify the species of Elasmobranchii landed in the waters of Sibolga City, North Sumatra Province, and to analyze the species composition, economic value, and conservation status. A descriptive method was employed through direct field observations conducted at the Sibolga Fish Landing Site (TPI) and Tangkahan Renta Sari from July to September 2024. The results showed a total of 17 Elasmobranchii species, consisting of 13 rays and 4 sharks. Species composition and abundance varied by location, with Neotrygon kuhlii being dominant at TPI Sibolga and Aetobatus narinari at Tangkahan Renta Sari. Most of the individuals caught were classified as adults, indicating intensive fishing pressure. Conservation status based on the IUCN Red List and CITES classification revealed that several species fall under threatened categories. These findings emphasize the need for proper fisheries management and conservation efforts to ensure sustainable exploitation of Elasmobranchii resources in Sibolga waters. This study provides essential baseline data for future conservation planning and fisheries policy development.
