Abstract

A 33-day experiment was carried out to investigate the effect of light at 80, 380, and 3800 lux and tank wall colour (black, grey, white, red, green, blue, clear) separately and in combination on growth, survival, yield, and size heterogeneity of peled Coregonus peled larvae. 7 groups of larvae in 3 repetitions were transferred to the experimental system. Each group comprised 300 larvae. Larvae were fed fresh live brine shrimp Artemia salina and artificial dry food LARVIVA ProWean. Significantly higher (p<0.05) survival was observed in black and white tanks in comparison with grey tanks. Significantly lower (p<0.05) size heterogeneity was observed in red and grey tanks compared to clear, black, green, and blue tanks, and in RD-H compared to
