Abstract

Abstract

Sebangki Village has a river namely the Sambeh River, which is in a secondary forest area. The condition of the Sambeh River and the surrounding forests has currently undergone changes, especially in terms of widespread land clearing for the social and economic needs of local communities. This research aims to examine the diversity of freshwater fish species in the Sambeh River, Sebangki Village, Sebangki District, Landak Regency. This research uses a survey method, data collection uses Purposive Sampling techniques. This research was carried out at 4 stations, each station was carried out 2 (two) repetitions. The results showed that 10 types of fish were caught in the Sambeh River. In these four stations, 7 different families of 10 species were found, namely Channidae, Cyprinidae, Osphonemidae, Helostomatidae, Anabantidae, Bagridae and Notopteridae. The dominance index value from the four stations ranges between (C) = 0.33 - 0.36, which means that no fish dominates the others. The species diversity value of the four stations ranges between (H') = 0.99 - 1.35, which means that species diversity is low. The species evenness value of the four stations ranges between (E) = 0.70 - 0.87, which means that the species evenness level is low or uneven. The species richness index value (R) = 0.62 "“ 1.38, which means there is low species richness. The similarity index values for stations 1 until station 4 are considered different and are considered significantly different.

Desa Sebangki memiliki Sungai Sambeh yang berada di kawasan hutan sekunder. Kondisi Sungai Sambeh, maupun hutan di sekitarnya saat ini telah terjadi perubahan, terutama dalam hal pembukaan lahan secara meluas untuk keperluan sosial dan ekonomi masyarakat setempat. Penelitian ini bertujuan mengkaji keanekaragaman jenis ikan air tawar di Sungai Sambeh Desa Sebangki Kecamatan Sebangki Kabupaten Landak. Penelitian ini menggunakan metode survei, pengumpulan data menggunakan teknik purposive sampling. Penelitian ini dilaksanakan pada 4 stasiun, setiap stasiun dilakukan 2 (dua) kali pengulangan. Hasil penelitian menunjukkan bahwa 10 jenis ikan yang ditangkap di Sungai Sambeh. Keempat stasiun tersebut ditemukan 7 famili berbeda dari 10 spesies, diantaranya Channidae, Cyprinidae, Osphonemidae, Helostomatidae, Anabantidae, Bagridae dan Notopteridae. Nilai indeks dominansi dari keempat stasiun berkisar antara (C) = 0,33 - 0,36, yang artinya tidak ada ikan yang mendominansi lainnya. Nilai keanekaragaman jenis dari keempat stasiun berkisaran antara (H') = 0,99 - 1,35, yang artinya keanekaragamn jenisnya rendah. Nilai kemerataan jenis dari keempat stasiun berkisaran antara (E) = 0,70 - 0,87, yang artinya tingkat kemerataan jenisnya rendah atau tidak merata. Nilai indeks kekayaan jenisnya (R) = 0,62 "“ 1,38, yang berarti terdapat kekayaan jenis yang rendah. Nilai indeks kesamaan stasiun 1 hingga stasiun 4 dianggap berbeda dan dianggap berbeda nyata.
