Keanekaragaman Jenis Ikan Di Sungai Jelai Desa Tebing Berseri Kecamatan Jelai Hulu Kabupaten Ketapang

Abstract

Abstract

The Jelai River is a river that passes through Tebing Berseri Village, Jelai Hulu District, Ketapang Regency. The aim of this research is to examine the diversity of fish species in the Jelai River, Tebing Berseri Village, Jelai Hulu District, Ketapang Regency. The expansion of plantation land is one of the causes of river pollution which causes erosion so that the river body widens and shallowing occurs. Determination of the sampling point is done by making observation stations which are placed by purposive sampling. The research was conducted in 6 (six) different locations, namely secondary forest areas (upstream), oil palm plantation areas, residential areas, sengeroyan river, sangkai river and pelenggang river. Each location is made 1 station. Each station is repeated 2 (two) times. The fishing gear used is spread nets, trawls, fishing rods, saplings, serua, sauk, and traps. The results showed that in the Jelai River, 31 species of fish were caught belonging to 12 families. The highest number of species is the family Cyprinidae, 12 species. Based on the calculation results, the value of the diversit of fish species in the six habitats is secondary forest habitat 2.816, oil palm plantation habitat 2.134, settlements 2.209, Senggeroyan river 2.573, Sangkai river 0 and Pelenggang river 2.616 which means the value of fish species diversity in the Jelai River is in the moderate category.

Sungai Jelai merupakan sungai yang melewati Desa Tebing Berseri, Kecamatan Jelai Hulu, Kabupaten Ketapang. Tujuan Penelitian ini adalah untuk mengkaji keanekaragaman jenis ikan di Sungai Jelai Desa Tebing Berseri Kecamatan Jelai Hulu Kabupaten Ketapang. Perluasan lahan perkebunan menjadi salah satu penyebab tercemarnya sungai yang menyebabkan erosi sehingga badan sungai melebar dan terjadi pendangkalan. Penentuan titik sampling dilakukan dengan membuat stasiun pengamatan yang diletakkan secara purposive sampling. Penelitian dilakukan di 6 (enam) lokasi yang berbeda yaitu daerah hutan sekunder (Hulu Sungai), daerah perkebunan sawit, daerah pemukiman penduduk, sungai Sengeroyan, sungai Sangkai dan sungai Pelenggang. Setiap lokasi dibuat 1 stasiun. Setiap stasiun diulang sebanyak 2 (dua) kali. Alat tangkap yang digunakan berupa jala tebar, pukat, pancing, tekalak, serua, sauk, dan bubu. Hasil penelitian menunjukan bahwa di Sungai Jelai ditemukan 31 jenis ikan yang tertangkap yang tergolong dalam 12 famili. Jumlah jenis terbanyak adalah famili cyprinidae 12 jenis. Berdasarkan hasil perhitungan, nilai keanekaragaman jenis ikan di keenam habitaitat adalah habitat hutan sekunder 2,816, habitat perkebunan sawit 2,134, Pemukiman 2,209, sungai Senggeroyan 2,573 , sungai Sangkai 0 dan sungai Pelenggang 2,616 yang berarti nilai  keanekaragaman jenis ikan di Sungai Jelai masuk kategori sedang.
