Abstract

This research aims to identify the structure of the bivalve community on the coast of Langkat Village, Pinolosian, South Bolaang Mongondow District. Sampling was carried out from December 2020 to January 2021 at three stations, namely seagrass beds (station I), tourist attractions (Station II), and mangroves (Station III), using the quadrant transect method, where each observation station made a line transect from the mainland towards the sea. Line transects are placed at each station, while the distance between line transects is 50 m. Observation results show that the bivalves at the research location consist of five families (Arcidae, Asteridae, Cyprinidae, Cardiidae, Ostreidae) an six types of bivalves, where the diversity index is low and the uniformity index is moderate, indicating that the distribution of each type is relatively even.Keywords: Bivalve; coastal; community structure; Lungkap

Abstract

Ikan layang (Decapterus macrosoma) merupakan ikan pelagis kecil yang memiliki nilai ekonomis penting dan banyak ditangkap di perairan Teluk Tomini, khususnya wilayah Gorontalo. Kajian tentang kelompok umur dan parameter mortalitas diperlukan karena tingginya aktivitas penangkapan dapat mempengaruhi kondisi stok sumberdaya ikan. Riset ini bertujuan menganalisis dinamika populasi ikan layang (Decapterus macrosoma) di perairan Teluk Tomini Gorontalo berdasarkan kelompok umur dan parameter mortalitas. Pengambilan data dilaksanakan pada Februari-Maret 2026 dengan jumlah sampel 800 ekor ikan melalui pengukuran panjang dan berat. Analisis menggunakan distribusi frekuensi panjang metode Bhattacharya dan length converted catch curve dengan FiSAT II. Hasil riset ini menunjukkan adanya dua kelompok umur yang didominasi ikan fase muda. Nilai mortalitas penangkapan yang tinggi dibandingkan nilai mortalitas alami menunjukkan tingginya tekanan penangkapan terhadap sumber daya ikan layang. Selain itu, nilai laju eksploitasi mengindikasikan bahwa pemanfaatan ikan layang telah berada pada kondisi overfishing. Oleh karena itu, diperlukan pengelolaan penangkapan yang berkelanjutan untuk menjaga kelestarian stok ikan di perairan Teluk Tomini
