(Bivalvia: Corbiculidae) di Kawasan Mangrove Segara Anakan, Cilacap}, journal = {Jurnal Kelautan Tropis}, volume = {18}, number = {2}, year = {2016}, keywords = {}, abstract = { Segaraanakan merupakan salah satu estuaria terbesar di Pulau Jawa yang terkenal dengan keanekaragaman hayatinya. Diantara biota yang terdapat adalah kerang totok (Geloina sp) yang berasosiasi dengan hutan mangrove. Karena memiliki nilai ekonomis maka selalu di tangkap. Maka dari itu sangat tepat jika kerang tersebut dipelajari ekologis maupun biologisnya. Tujuan dari penelitian ini adalah untuk mengetahui distribusi dan stuktur populasi kerang Geloina sp tersebut. Penelitian dilakukan di Segaraakan Cilacap pada empat stasiun yang berbeda salinitasnya (13, 15, 30 dan 32 ppt). Sifat penelitian adalah studi kasus, metoda pengambilan sampel yang digunakan adalah metoda sampling area. Data yang diambil meliputi kerang dan kondisi perairan. Data yang didapatkan dikelompokan berdasarkan kelas ukuran panjang cangkang selanjutnya dilakukan uji chi kwadrat untuk menentukan pola sebaran.Hasil penelitian menunjukan kerang yang didapat adalah G. erosa dengan pola sebaran merata pada keempat stasiun penelitian yang berbeda salinitasnya. Adapun kepas ukuran kerang yang didapat dalam keempat stasiun dapat dikelompokan menjadi kelas ukuran <3, 3 – 3,9, 4 – 4,9, 5 – 5,9, 6 – 6,9, 7 – 7,9, .>8 cm.

One of fauna found which associate with the mangroves was totok mussel Geloina sp. That mussel had economic value so that faced high exploited along season. Considering that condition a study of distribution and their population structure was very importance. The research was carried out on Segaraanakan Cilacap on different station which had different salinity (13, 15, 30 and 32 ppt). The case study type research and sampling area method was used to collect the data of information of the Geloina sp. The data collected in the field was mussel population and water quality condition where the mussel life. The data of mussel was grouping in several length of class and following chi quadrant test to define the distribution of Geloina sp. The result of the study showed, Thad the Geloina sp was uniform distribute along the fourth station which had different salinity and the length of class mussel was found <3, 3 – 3,9, 4 – 4,9, 5 – 5,9, 6 – 6,9, 7 – 7,9, .>8 cm.
