Pemeliharaan Benih Ikan Jelawat (Leptobarbus Hoeveni BLKR) Dengan Padat Tebar Yang Berbeda Pada Sistem Resirkulasi Dan Akuaponik
This research was conducted for 30 day from 28 September until 28 Oktober 2014, at Laboratory Aquaculture of Technology Universitas of Riau. The aim of the study was to determine the effects of stocking density of fish Jelawat (Leptobarbus hoeveni Blkr) and raised on a system the recirculation aquaponic. The method used in this research was experimen with three treatment and three replications. The treatments were density of 20, 30, 40, and 40 kemangi (Ocimum sanctum L) of each treatment.
The result of research is treatment 30 fish/ 100 liter with absolute growh weight 3,03 g, the length of the absolute 1,67 cm, and daily growth rate 1,99% and the survival rate 90%. The best water quality parameters recorded during in the research period was achieved by. 30 fish/100 liter of ammonia (NH3) 0,6602-0,2942 mg/l, nitrite (NO2) 0,1104-0,0893 mg/l, nitrate (NO3) 0,1598-0,0972 mg/l, temperatur 27-30oC, pH 5,5-6, dissolved oxygen (DO) 4,41-5,48 mg/l, and (CO2) 7,07-10,73 respectively.
