Table 1 Descriptive statistics for weight (g) and length (cm) of the fish and fin length (cm) and fin erosions (%) at three recording times

From: Direct and social genetic parameters for growth and fin damage traits in Atlantic cod (Gadus morhua)

Fin erosion       
First dorsal (%)      2062 23.09 (15.20)
Second dorsal (%)      2061 14.32 (9.95)
Third dorsal (%)      2060 10.39 (5.49)
Caudal (%)      2060 13.34 (8.18)
  1. Fin erosions were only scored at the end of the experiment (recording 3); growth rate and change in condition factor were calculated from weight and length recordings.
