[Proteinase activity in the early developmental stages of the carp, Cyprinus carpio].
Embryonic and early postembryonic development of the carp is associated with an increase in the content of soluble proteins and nitrogen of non-protein nitrogenous components. Simultaneously, the activity of trypsin-like and chemotrypsin-like peptide hydrolases increases together with the increase in the degree of proteolysis. These data suggest that the development of carp embryos and early larva is accompanied by intensification of two opposite processes--synthesis and catabolism of proteins. The observed changes are more evident in early postembryonic period as compared with the early stages of embryogenesis.
