The relationship between feed efficiency, growth and group dominance dynamics in turbot (Scophthalmus maximus)
Variation among families of turbot (Scophthalmus maximus) in growth, feed efficiency, and body weight variation was investigated. A total of 672 turbot (Scophthalmus maximus) originating from eight families (84 full-sibs per family) were used in this experiment. Body weight (BW) was recorded individ...

Variation among families of turbot (Scophthalmus maximus) in growth, feed efficiency, and body weight variation was investigated.
