Keanekaragaman Ikan di Sungai Sembahe, Kabupaten Deli Serdang

Abstract

The diversity of fish in Sembahe river, Deli Serdang has been observed in November 2016. Determining the location of the point of the study using the ‘’Purposive Random Sampling’’. Six species of fish that obtained from observation sites are classified into two ordos (Cypriniformes, Siluriformes) 3 family (Bagridae, Cyprinidae, Sisoridae). The index diversity of fish in Sembahe river classified very low with a value between 1,083-1,497. The water current velocity, DO, oxygen saturation, and Nitrat had a very strong correlation and positif value in 0,980-0,996

Keanekaragaman ikan di Sungai Sembahe, Kabupaten Deli Serdang telah diteliti pada bulan November 2016. Penentuan titik lokasi penelitian menggunakan metode ‘’Purposive Random Sampling’’. Enam spesies ikan yang diperoleh dari lokasi penelitian diklasifikasikan ke dalam 2 ordo (Cypriniformes, Siluriformes) 3 famili (Bagridae, Cyprinidae, Sisoridae). Nilai indeks keanekaragaman (H’) ikan di Sungai Sembahe tergolong sangat rendah berkisar antara 1,083-1,497. Kecepatan arus, oksigen terlarut (DO), kejenuhan oksigen, dan nitrat berkorelasi sangat kuat dan positif berkisar antara 0,980-0,996.
