Effects of 12 factors on burbot Lota lota (L., 1758) weaning performances using fractional factorial design experiment
International audience Sixteen weaning protocols for burbot were tested by using a fractional factorial design experiment taking into account 12 factors (feeding, environmental and stocking density factors) with two modalities. A high survival rate (76%), associated with the lowest cannibalism rate...
