Abstract

Desa Pematang Cengal mempunyai sebagian besar wilayah pesisir dengan keanekaragaman bivalvia yang dimanfaatkan sebagai makanan. Akan tetapi belum ada catatan tentang keanekaragaman bivalvia di Desa Pematang Cengal. Penelitian ini dilakukan pada Mei-Juni 2023 yang bertujuan untuk menganalisis keanekaragaman bivalvia dari hasil tangkapan nelayan di Desa Pematang Cengal, Tanjung Pura, Sumatera Utara. Metode pengambilan sampel dilakukan secara observasi dan survei langsung pada 3 stasiun berbeda, yaitu stasiun I Alur Kapal, stasiun II Pangkalan Garip, dan stasiun III Paluh Nipah. Data juga diperoleh melalui wawancara dengan nelayan terkait spesies bivalvia yang ditemukan serta alat tangkap yang digunakan. Hasil penelitian menunjukkan bahwa terdapat 10 spesies bivalvia dari 5 famili yang ditemuka pada ketiga stasiun. Spesies yang ditemukan yaitu, Atrina pectinata, Anadara antiquata, Meretrix meretrix, Modiolus modulaides, Perna viridis, Anadara granosa, Barbatia foliate, Tellina timotensis, Pinctada albina, dan Pitar tumens. Spesies yang dominan adalah Meretrix meretrix dari famili Veneridae. Indeks keanekaragaman (H') di tiga stasiun tersebut berkisar antara 0-1.19. Indeks keanekaragaman tertinggi terdapat pada stasiun I sebesar 1.19, kedua terdapat pada stasiun III sebesar 0,97, dan indeks keanekaragaman terendah terdapat pada stasiun II sebesar 0.

Abstract

The This study aims to determine the diversity, morphology, and morphometric studies of shrimp caught by fishermen in the coastal area of Pematang Cengal Village, Tanjung Pura, North Sumatra. The study was conducted on June 9-12, 2025, using a quantitative descriptive method. Sampling was carried out through interviews with fishermen and direct observation of the catch. The results of the study found 10 species of shrimp consisting of 3 families (Penaeidae, Palaemonidae, and Squillidae) from 2 orders (Decapoda and Stomatopoda). The shrimp species found were Penaeus merguiensis, Penaeus monodon, Palaemonid shrimps, Harpiosquilla raphidea, Parapenaeopsis sculptilis, Penaeus indicus, Metapenaeus affinis, Litopanaeus vannamei, Macrobrachium rosenbergii, and Metapeneus brevicornis. Morphometric measurements showed different variations between shrimp species. Based on total length, the size of shrimp caught in the Pematang Cengal Village Coastal Area is relatively stable and falls into the medium-sized category. This research provides important information regarding shrimp species diversity in the Pematang Cengal Village coastal area and can serve as a starting point for shrimp resource conservation in the area.
