Effects of starvation stress on body shape, chemical composition and blood physiological of Cyprinus carpio

Abstract:

The aim of the present study was to determine the effect of starvation on body appearance,muscle Composition and blood physiolgical of the carp (Cyprinus carpio) at the water temperature 18-20℃ in the cycle and flow water aquarium. The experiment was designed for four groups with three replication, which were 0 day(control), 10 days, 20 days, 30 days group. The results showed：With the carp hunger time extending,there was a trend to decline for the obese relative,intestine and body length ratio, live index of the carp, but the effects was not significantly(P>0.05); there was a trend to increase for contents of moisture, crude ash in the body muscle of the carp,but a trend to decline for the crude fat in the body muscle of the carp, and the differences was not significantly (P>0.05),while body contents of crude protein was remarkable difference（P<0.05）; With the carp hunger time extending, red blood cell quantity and hemoglobin value dropped significantly（P<0.05）,and white blood cell quantity decreased not significantly (P>0.05), blood glucose levels rasied first and then went down. The experiment illustrated that the carp body appearance had changed, and with the prolongatin of starvation,the muscle fat was decompose to exploit first,the muscle protein then to be used,at the same time ,the body physiological of the carpwas changed to be fit for the starvation condition.
