A stepwise multiple regression analysis was conducted for analysing the variations of fish growth (G, mg WM day−1) against the wet body mass of fish (WM, mg), fish density (FD, fish L−1), feeding level (FL, nauplii fish −1 meal−1) and prey density (PD, nauplii mL−1). The analysis was restricted to the data collected until 144 hah for the following reason. From 144 to 192 hah, the growth of fish fed 1 or 3 RFLwas slower than on the previous days (Fig. 3), which
