DOI : 10.4194/1303-2712-v16_2_06 Viewed : 2481 - Downloaded : 2205 A dietary study was conducted to investigate the effect of partly substituted levels of fish meal in feed for juvenile (140- 500 g) turbot (Scophthalmus maximus Rafinesque) on growth performance. The experimental diets were formulated to contain 53, 73 and 93 % fish meal protein and different levels of plant protein substitutes (wheat meal, corn gluten meal, soybean meal and canola meal) with three replicates for each diet. Fish fed 53% fish meal diets had lower final mean weights compared to fish fed the 93% fish meal diet, whereas the 73% fish meal group displayed intermediate values. However, only minor differences were found in specific growth rate, feed conversion ratio, daily feed intake and total feed consumption between dietary treatment groups. Overall the findings demonstrate that substitution of fish meal by plant protein raw materials down to 53 % fish meal protein (44% replacement) does not affect overall specific growth rate, feed conversion ratio or feed intake in juvenile turbot (<500 g).
