| Popis: | An experiment was performed to study the effects of three protein/energy ratios (A=25, B=22×10−3 and C=19×10−3 mg kJ−1) on zootechnical (growth, feed intake, feed efficiency and survival), technological (heterogeneity, gutting and filleting yield), flesh quality (composition, texture and flavour) and environmental (nitrogen pollution) parameters relative to Eurasian perch. The experiment was carried out in triplicate (85 fish) during an 18-week period, from 35 g to commercial size (150 g). The fish were fed by hand twice a day to satiation and the daily feed intake was recorded. During the last period (week 12 to week 18), growth was significantly higher (P |
