Effects of different periods of starvation and compensatory growth on growth indices and hematological parameters in common carp (Cyprinus carpio).
Abstract:   (151 Views)

Starvation periods of fish in during the developmental stages on growth indices and blood factors can be affected. The effects of compensatory growth on growth indices and physiological responses (glucose, total protein and cholesterol), study for 8 week investigated in Juveniles of common carp (Cyprinus carpio). The fish were divided in 4 experimental groups with initial weight (13/88±0/88 gr) in triplicate that included: 0 (T1) 2 days (T2), 4 days (T3) and a week (T4) starvation and refeeding periods each with 3 replicates were suffered. At the end of testing blood samples for biochemical analysis of each of the treatments used and metabolites were measured by spectrophotometry methode. Results showed growth indices including the final weight, growth rate, specific growth rate and body weight gain in the control and treatment 2 days a week of starvation were significantly different (p<0.05) but between treatments 1 day starvation and control there was no significant difference (p>0.05). The condition factor and feed conversion ratio in all treatments no significant difference (p>0.05). glucose levels between treatment starvation and control groups showed significant differences (p<0.05) but the total protein and cholesterol were not significantly different between control and starved treatments (p>0.05). The results suggest that commomcarp has the physiologic adjustment ability to short-term starvation and re-feeding period.
