Title: Effects of Four Kinds of Metal Ions on Amylase Activities in Red-white Ornamental Carp
Abstract: By the way of enzyme analysis,effects of four kinds of metal ions(K+,Na+,Mg2+,Ca2+)on amylase activities in hepatopancreas,foregut,midgut and hindgut of red-white ornamental carp were studied.The results indicated that the effects of four metal ions on amylase activities of red-white ornamental carp was different in the range of experimental concentration from 25mmoL/L to 150mmoL/L.K + and Na+ could promote amylase activities in hepatopancreas,foregut,midgut and hindgut at different degree,Mg2+ could promote amylase activities in hepatopancreas,foregut and hindgut but inhibit amylase activities in midgut.Ca2+ could inhibit amylase activities in the intestine at different degree,but it had no different inhibitory in amylase activities in the hepatopancreas of red-white ornamental carp.
