Influence de la photoperiode sur la croissance et la survie de la larve et du juvenile de sole (Solea solea) en elevage

摘要: Abstract The effect of photoperiod on survival and growth cultured young soles ( Solea solea ) was investigated from hatching to the age three months, at 18° C. Two experiments were performed, comparing days with 12, 18 24 h light. fishes reared in 60 1 tanks, conical ones before metamorphosis, square a sandy bottom metamorphosis months. They fed live food organisms for month, frozen flesh bivalve Laevicardium crassum two other ones. During larval period, no significant difference recorded rate but better obtained light, suggesting predominant diurnal feeding. From months (mean weight: g) juveniles could be demonstrated.
