Potensi Kepiting Bakau (Scylla Spp) Pada Ekosistem Mangrove Di Kota Bengkulu
Abstract
Kepiting bakau merupakan salah satu komoditas perikanan yang memiliki potensi sebagai penyangga kehidupan masyarakat terutama bagi nelayan sekala kecil. Ekosistem mangrove mempunyai peran penting sebagai habitat utama bagi kepiting bakau(Scylla Spp). Penelitian tentang potensi kepiting bakau (Scylla spp) pada ekosistem mangrove guna mengetahui kondisi populasi kepiting bakau di alam sehingga dapat menjadi acuan dalam mengatur penangkapan dan sebagai landasan kebijakan pengelolaan penangkapan kepiting bakau untuk menjamin usaha penangkapan kepiting bakau secara berkelanjutan dan berkesinambungan. Penelitian ini berdasarkan 3 jenis kerapatan mangrove, setiap stasiun dibagi menjadi 3 transek garis dengan masing-masing 4 plot (ukuran 10x10 m) tiap transek garis. Tiap plot di pasang bubu sebanyak 2 buah pada setiap minggu selama 4 bulan (Juli-Oktober). Hasil pada ekosistem mangrove di Kota Bengkulu memiliki potensi kepiting bakau sebanyak 1.183 ekor. Secara keseluruhan habitat kepiting bakau pada perairan kota bengkulu sangat mendukung dalam menunjang kehidupan kepiting bakau dengan keberadaan kerapata mangrove jarang, sedang dan rapat yang memiliki 7 jenis mangrove yaitu yaitu R.apiculata,S.alba, B.gymnoriza, A.lanata, X.Granatum, K.candel dan L. littoreae. Memiliki kisaran parameter fisika kualitas air suhu -29,250C, salinitas 11-26,250/00, pH 6,95-7,55 pasang tertinggi 80-106,25 cm dan kandungan C-Organik 4,18-5,83%. Hubungan total tangkapan kepiting dengan kerapatan mangrove dan Hubungan total tangkapan kepiting dengan kandungan C-organik pada sedimen masing-masing kedua variabel memiliki pengaruh hubungan yang kuat dengan nilai koefisien determinasi (R2) sebesar 80% dan 90%.nilai koefieien korelasi (r) di peroleh 0,89 dan 0,95.
