Kelimpahan Gastropoda Jenis Telescopium sp., Pada Kawasan Mangrove Desa Tanjung Tiram Sulawesi Tenggara

Abstract

This study aims to determine the abundance of gastropods of the Telescopium sp. type, in the mangrove area of ​​Tanjung Tiram Village, Southeast Sulawesi. This gastropod abundance study is needed to determine the trophic level of gastropods in the food chain in the mangrove ecosystem area in Tanjung Tiram Village, so that the community, especially shellfish farmers, can make key locations for finding gastropod shellfish and can be used as a scientific basis for the cultivation and management of shellfish fisheries in the mangrove ecosystem. Gastropod biological data, in the form of morphometrics (shell length and weight) of gastropods were observed in the laboratory. Then for the parameters of the aquatic environment in the form of water and substrate samples were further analyzed in the Biology Laboratory of the UHO Forensic and Biomolecular Unit using the Miller triangle sediment fraction method and the APHA standard method. Statistical data analysis was carried out using the Excel Stat and SPPS applications. The results obtained showed that the highest abundance of gastropods at the research location was shown at station 3 with an average value of 4.45 ind/m² and the lowest was at station I with an average value of 2.75 ind/m²

 ABSTRAK

 Penelitian ini bertujuan untuk mengetahui kelimpahan gastropoda jenis Telescopium sp., di kawasan mangrove desa Tanjung Tiram Sulawesi Tenggara. Penelitian kelimpahan gastropoda ini dibutuhkan untuk mengetahui tingkatan trofik gastropoda dalam rantai makanan pada kawasan ekosistem mangrove di Desa Tanjung Tiram, sehingga masyarakat khususnya para petambak kerang dapat menjadikan lokasi kunci untuk mencari kerang gastropoda serta dapat dijadikan sebagai dasar ilmiah untuk budidaya dan pengelolaan perikanan kerang-kerangan di ekosistem mangrove. Data biologi gastropoda, berupa morfometrik (panjang cangkang dan beratnya) gastropoda diamati di laboratorium. Kemudian untuk paramater lingkungan perairan berupa sampel air dan substrat dianalisis lebih lanjut di Laboratorium Biologi Unit Forensik dan Biomolekuler UHO menggunakan metode fraksi sedimen segitiga Miller dan metode baku APHA. Analisis data statistik dilakukan menggunakan aplikasi Excel Stat dan SPPS. Hasil yang diperoleh menunjukkan kelimpahan gastropoda tertinggi di lokasi penelitian ditunjukkan pada stasiun 3 dengan nilai rata-rata 4,45 ind/m² dan terendah adalah pada stasiun I dengan nilai rata-rata 2,75 ind/m².
