Description:
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.
