Figure 4.

Effects of water temperature and routine feeding on the relationships of trypsin with chymotrypsin and with the activity ratio of trypsin to chymotrypsin (T/C ratio) in Atlantic salmon parr reared at 6 °C (×) and 10 °C (D), regardless of trypsin phenotypes (a) and (b), and according to trypsin phenotypes at 6 °C (c) and 10 °C (d). The enzyme specific activities of trypsin and chymotrypsin are expressed as µmol p-nitroaniline h⁻¹ mg protein⁻¹. ns, not significant.
