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
WH-H, WH-M, WH-L, CL-H, CL-M, CL-L, BK-H, BK-M, BK-L, GN-H, GN-M, GN-L, BE-H,
BE-M, BE-L, GY-H, and RD-M compared to WH-M, WH-L, CL-H, CL-M, CL-L, BK-H, BKM, BK-L, GN-H, GN-M, GN-L, BE-H, BE-M, BE-L, and RD-L, GY-L, GY-M compared to
WH-L, CL-H, CL-M, CL-L, BK-H, BK-M, BK-L, GN-H, GN-M, GN-L, BE-H, BE-M, BE-L.
Based on our results, peled larvae are independent of light intensity. Rearing of peled
in black tanks can be recommended for the highest survival.
