Abstract

The effects of starvation for 60 and 135 days on some metabolites in blood, liver and muscles were studied in common carp(Cyprinus carpio ). During the first 60 days, the common carp apparently tended to utilize liver triglycerides as energy source. An increased liver aspartate amino transferase (AST),alanin amino transferase (ALT) activity and maintenance of glycogen levels suggested a stimulated gluconeogenesis. Between 60 and 135 days, the common carp utilized great amounts of both liver and muscular triglycerides .There was also a marked decrease in liver glycogen during this later phase of starvation. The starvation also resulted in a significant decrease in blood glucose, after 60 and 135 days.
