Preliminary results on the somatic and body compositional changes in juvenile common carp during long-term starvation

The aim of our study was to analyse the body compositional changes in common carp juveniles during 12-week-long starvation. Food restriction had a significant impact on every parameter. Hepatosomatic index, viscerosomatix index and condition factor decreased linearly, while in case of body composition parameters a slight fluctuation can be observed. Body fat and dry matter content decreased, protein and ash increased due to 12-week-long starvation. It can be concluded that body lipids constituted the major energy source for starved carp juveniles and 12-week-long starvation did not induce proteolysis in tissues.
