KERAGAMAN JENIS IKAN HIAS DAN KONDISI PERAIRAN DI KESATUAN HIDROLOGIS GAMBUT SUNGAI MEMPAWAH-SUNGAI DURI, KALIMANTAN BARAT

Perairan rawa gambut menyimpan potensi ikan hias yang unik dengan keragaman jenis berbeda dibanding hidup di perairan air tawar lainnya. Karena terbiasa pada kondisi fisik kimia tidak biasa, menyebabkan banyak dari belum dapat dipijahkan dan masih mengandalkan penangkapan alam. Di sisi lain, kelestarian beberapa menjadi terancam karena dikonversi seperti Kesatuan Hidrologis Gambut (KHG) Sungai Mempawah-Sungai Duri Kabupaten Mempawah, Kalimantan Barat. Kegiatan ini bertujuan untuk mengetahui karakteristik habitat KHG Duri, Informasi didapat akan dasar melakukan rekayasa lingkungan dalam adaptasi domestikasi lahan gambut. Penelitian dilakukan saluran irigasi buatan terdapat perkebunan sawit daerah Sebukit Sawit. Penangkapan menggunakan jaring, pancing, bubu, seser diberi umpan pakan pelet. Namun hanya bubu menghasilkan tangkapan ikan. Dari hasil uji coba penjeratan diperoleh antaranya Puntius rhomboocellatus, Rasbora trilineata, Desmopuntius johorensis (Duncker, 1904), dorsiocellata, sepat (Trichogaster sp.), cephalotaenia. Karakteristik wilayah tersebut kecepatan aliran sangat lambat (tergenang), pH asam (pH 3-4), kelarutan oksigen sedang (2-3 mg/L), berwarna merah hitam teh kecerahan sekitar 20 cm. bagian pinggir rumput-rumputan menjorok ke Hasil penelitian menggambarkan bahwa cukup rendah didominasi rhomboocellatus cephalotaenia.Peat swamp waters (black water) usually have diverse, unique, and attractive fish species, which often the potential as ornamental fish. However, due to uniqueness adaptation water quality condition, black fishes’ culture, breeding technology not yet been fully understood, resulting in reliance on wild capture. On other side, many of peat areas were converted palm plantations such Peatland Hydrology Unitary Mempawah River-Duri River, West Kalimantan. This study aimed build a biodiversity inventory species their characteristics Hydrological Unit The information obtained serves baseline for environmental engineering adapt domesticate fishes. was conducted two irrigation channels located oil Anjongan-Sawit. These locations are swamps once different samples caught by hand net, cast angler, trap using artificial bait or pellet. Only net successful capturing included rhombocellatus, Trichogaster sp., condition characterized very slow-moving mass (<1 m/minute), acidic moderate dissolved oxygen typical brightness (± cm). Overgrown bushes grasses along natural habitats these species. concludes that diversity this area is relatively low dominated P. R.
