摘要: The aim of the study was to optimize burbot juveniles rearing in recirculating aquaculture system. In experiment 1 (17 °C, photoperiod 24L:0D), fish (initial: body weight [W] = 15.36 ± 3.72 g, standard length [SL] 12.48 1.09 cm) were divided into four groups (I, II, III and IV). Different feeding levels applied: 1, 2, 3 4 % biomass daily (counted based on dry feed weight). conversion ratio (FCR) specific growth rate (SGR) recorded. 2 level day−1), (W 5.24 2.43 g SL 8.54 1.24 two where different light conditions applied (I: 24 h [1,800 lx] II: darkness [4 lx]). highest SGR recorded group II (1.93 whereas lowest (1.27 day−1) final W (P 0.05). consumption I reached 100 %, it 71.3 0.05; between 23.33–23.35 g; P > results from indicate that day−1 most efficient. Also, proven, for first time, there no effect using constant conditions.
