duration of grow-out testing (Table 5). Mean harvest weight of the
G4-generation was 49% and 130% larger than the mean harvest
weights of the G0- and G1-generations, respectively. The male/female ratio at harvest varied between 1.01 and 1.38 suggesting
higher survival rates of males. The males had, in average, 35.4%
larger harvest weights than females (range 23.0–53.2% in different
generations). The mean coefficient of variation (CV) of recorded
body weights was 38% at tagging, 41% at mid-recording and 34%
at harvest
