Daftar Isi:
- Penelitian ini bertujuan untuk menganalisa aspek ekologi (habitat, distribusi ukuran panjang, pola pertumbuhan), dari ikan Kulari (Lobocheilos falcifer C.V : Cyprinidae) di Sungai Batang Kuranji, Padang. Pengambilan sampel dilakukan dengan metode survei dengan teknik pengambilan sampel stratified random sampling. Didapatkan hasil penelitian terhadap faktor fisika kimia perairan dengan nilai suhu rata-rata 26,550C, pH 5,6, O2 5,78 mg/l, BOD5 0,79mg/l, CO2 1,81 mg/l, TSS 0,51, kedalaman 40,88 cm, dan kecepatan arus 0,50 m/s. Hasil pengamatan terhadap pola pertumbuhan ikan kulari menunjukkan ikan jantan bersifat allometrik negatif dan ikan betina bersifat isometrik Kata kunci: Aspek ekologi, Ikan kulari (Lobocheilos falcifer), Sungai Batang Kuranji
- This research was carried out.in January-June 2013. This research aimed to analyze some ecological aspects (habitat, body length, distribution, growth pattern) in Kulari fish (Lobocheilos falcifer C.V : Cyprinidae) at Batang Kuranji river, Padang. This studied use survey method with stratified random sampling technique (at three locations) to collected samples. The result of this study showed that water temperature has 26,550C; pH 5,6; O2 5,78 mg/l; BOD5 0,79mg/l; CO2 1,81 mg/l; TSS 0, 51; depth 40.88 cm, and current velocity 0.50 m/s. The growth patterns of kulari fish showed that male fishes were in negative allometric and female fishes were in isometric.
