PPI Lhok Seudu yang berlokasi di Kecamatan Leupung, Kabupaten Aceh Besar, merupakan salah satu pusat pendaratan ikan di pesisir barat Aceh dengan potensi perikanan yang tinggi. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis ikan yang didaratkan, menghitung tingkat keanekaragaman spesies, serta menganalisis hubungan panjang dan berat ikan. Penelitian dilaksanakan pada April hingga Juni 2025 menggunakan metode survei langsung. Hasil identifikasi menunjukkan terdapat 81 spesies ikan yang tergolong dalam 55 genus, 34 famili, dan 19 ordo, dengan dominasi ordo Perciformes. Famili dengan jumlah spesies terbanyak adalah Lutjanidae (12 spesies), diikuti oleh Carangidae (11 spesies), Scombridae (9 spesies), dan Serranidae (6 spesies). Keanekaragaman spesies selama sembilan hari pengamatan berada pada kategori sedang, dengan indeks Shannon-Wiener (H’) berkisar antara 1,34 hingga 1,47. Spesies terbanyak secara individu berasal dari kelompok ikan pelagis kecil, terutama famili Engraulidae dan Leiognathidae. Berdasarkan data IUCN, mayoritas spesies (91%) berstatus Least Concern (LC), dan satu spesies tercatat dalam Appendix II CITES. Analisis hubungan panjang dan berat menunjukkan pola pertumbuhan bervariasi, dengan sebagian besar ikan pelagis kecil mengalami pertumbuhan allometrik negatif hingga mendekati isometrik. Temuan ini mencerminkan potensi ekologi yang tinggi di perairan PPI Lhok Seudu serta pentingnya pengelolaan perikanan yang berkelanjutan.

PPI Lhok Seudu, located in Leupung Subdistrict, Aceh Besar District, is one of the key fish landing centers on the western coast of Aceh, with high fisheries potential. This study aims to identify the fish species landed, determine the species diversity level, and analyze the length-weight relationships of the fish. The research was conducted from April to June 2025 using direct survey methods. The identification results revealed a total of 81 fish species belonging to 55 genera, 34 families, and 19 orders, with the order Perciformes being the most dominant. The families with the highest number of species were Lutjanidae (12 species), followed by Carangidae (11 species), Scombridae (9 species), and Serranidae (6 species). Species diversity during the nine days of observation was categorized as moderate, with Shannon-Wiener index (H’) values ranging from 1.34 to 1.47. The most abundant individuals came from the small pelagic fish group, particularly from the families Engraulidae and Leiognathidae. According to IUCN data, the majority of species (91%) were classified as Least Concern (LC), and one species was listed in CITES Appendix II. The analysis of length-weight relationships showed varied growth patterns, with most small pelagic fish exhibiting negative allometric to near-isometric growth. These findings reflect the high ecological potential of the PPI Lhok Seudu waters and underscore the importance of sustainable fisheries management.
