Effect of Different Dietary Protein Concentrationon Hematological Parameters of Fingerling Sparidentex hasta

Sparidentexhasta is a beneficial and economical fish in the Persian Gulf that these years much attention has been paid to and is a good candidate for marine aquaculture in coastal zones of Iran. Optimal levels of dietary components ensure optimum growth and health of fish. In this paper، feeding the Sparidentexhasta with different levels of protein and amino acidwas carried out in order to investigate their effects on hematological parameters. After adaptation in 2 weeks by a lipid-free diet، the fish of (30 to 35gr) were fed for 8 weeks by experimental diets in 300 L tanks (n=36). The fish were fed two times a day at 10:00 am and 17 pm with 4 proteinlevels (45%، 50%، 55% and 60%) that was repeated 3 times in 60 days. At the end of the experiment، the blood samples were taken by heparinized syringes. Then RBC and WBC were counted. Hematocrit، Hemoglobin and blood indices showed no significant difference in different groups. The results of hematological parameters showed that the used diet was in optimal condition for culturing Sparidentexhasta.
