Pemeliharaan Benih Ikan Jelawat (Leptobarbus hoeveni Blkr) dengan Padat Tebar Yang Berbeda Pada Sistem Resirkulasi dan Akuaponik
ABSTRACT: This research was
conducted for 30 day from 28 September to 28 Oktober 2014, at Laboratory
Aquaculture of Technology Universitas of Riau. The aimed of the study was to
determine the effects of stocking
density of Jelawat fish (Leptobarbus hoeveni Blkr) on the recirculation
aquaponic system. The method this research was experiment with three treatments
and three replications. The treatments were density of 20, 30 and 40 fish per
100 L waters, and 40 kemangi (Ocimum sanctum L) of each treatment. The best result of this research was on
treatment 30 fish/ 100 L with absolute growht 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 L 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
5.5-6.0 dissolved oxygen (DO) 4.41-5.48 mg/L, and (CO2) 7.07-10.73 mg/L
respectively
