Figure 4. Growth of transgenic (A) and wild-type (B) coho salmon juveniles.

Juveniles were reared from first-feeding until an age of 120 days at temperature from 8 to 18°C. Different letters denote significant differences at the p<0.05 level (Tukey's post hoc test) on ln-transformed values after 120 days (figures based on raw values). Note the more than 10-fold larger Y-axis scale for the transgenic fish.
