Abstract

 This study was conducted to investigate the effects of periods of STARVATION and REFEEDING on somehematological, serum parameters and whole body PROXIMATE COMPOSITION in CASPIAN SALMON (Salmo truttacaspius).240 samples of the CASPIAN SALMON with an average weight of 13.73±0.63 g were kept in 300 literpolyethylene tanks. Samples were fed twice a day with Rainbow trout commercial feed to the point of satiation. This experiment lasted for 10 weeks with control (without STARVATION) and 3 STARVATION treatments including 2, 4 and 6 weeks of STARVATION followed by 4 weeks of REFEEDING with 3 replicates. During rearing period, the averageof water temperature, pH and dissolved oxygen were 14.15±0.27oC, 8.44±0.17 and 6.34±0.24 mgl-1, respectively. At the end of STARVATION period, the results of BLOOD PARAMETERS showed that STARVATION significantlyincreased red blood cells and hematocrit in treatment with 2 weeks of STARVATION (0.893±0.58×106/mm3) and 6weeks of STARVATION (42.33±3.21%, P<0.05), respectively. At the end of trial, the highest value of white bloodcells belonged to 6 weeks STARVATION treatment (14.2±0.12×103/mm3) while the lowest (10±0.60×103/mm3) was observed in the control. Results of the biochemical serum parameters indicated the lowest amount of totalprotein (1.71±0.88 mg/dl) and glucose (41.35±1.44 mg/dl) were obtained in 6 weeks STARVATION treatment, rightafter the STARVATION period (P<0.05). At the end of the STARVATION period, the whole body protein content ofcontrol was lower than other treatmens (P<0.05), but after 2 weeks of REFEEDING, whole body protein content of 2and 4 weeks STARVATION treatments didn' t show any significant difference compared to control (P>0.05). At theend of the experiment, the lowest value of lipid belonged to STARVATION treatments while the highest value wasobserved in control (P<0.05). Generally, this can be inferred that CASPIAN SALMON fish can tolerate STARVATION for2 weeks without any negative impact on blood and serum biochemical parameters and for 4 weeks on wholebody PROXIMATE COMPOSITION.
