Effects of short-term starvation on biochemical carcass composition, liver glycogen and fat in Silver seabream fingerlings, Sparidentex hasta
Both in nature and in aquaculture, fishes coulde xperience periods of food deprivation or starvation. The present study was investigated the effect of starvation on biochemical body composition, glycogen and fat of liver in Sobaity fingerling. In this study, 300 fingerlings of Sparidentex hasta studied with mean weight 28.47 ± 0.24 g that included four treatments each with three replicates (25 fish per replicate) in a 300-liter polyethylene tanks. Fish of control treatment were fed to saturation twice daily and other treatments of were starved 2, 4 and 8 days. Biochemical composition of liver and carcass were performed at the beginning and end of the period of starvation and samples were transported to the laboratory for analysis . The results of this study showed that 2 days of food deprivation did not affect any of the factors studied (P>0.05), also 4 days of food deprivation was significantly affected on liver glycogen only (P<0.05), but 8 days of food deprivation was significantly effected on liver glycogen, fat and protein of body composition (P<0.05). According to the results of this study it can be stated that; in Sobaity fish, the first priority was the use of liver glycogen stores in food deprivation times; this shows the key role of the liver as the provider of fish body's energy needs, and the next priority was the use of fat and protein stores.
