Abstract:
Almost 300 species of marine algae has been identified in south of Iran that they were classified in groups of red algae (Rhodophytes), brown algae (Phaeophytes) and green algae (Chlorophytes). Among seaweed, Gracilaria made due to high production and extraction of economic value such as agar, one of the most important algae. Graclaria algae are Gracilariaceae family and red algae (Rhodophyta) category. The aim of this study was to investigate the effect of algae powder as additives in the diet Grasilaria Asian Sea bass (Lates calcarifer) on hematological parameters were. For this purpose, 120 Asian sea bass fish with an average weight of 28 ± 8/1g in 4 treatments and 3 replications in twelve 300-liter fiberglass tanks (10 fish per tank) was divided. The treatments based on each of the four diets containing 0, 1.5, 2 and 2.5 percent algae powder Gracilaria per kg food was prepared. At the end of the experiment the fish tail vein stem collected blood samples and blood parameters were measured. The results of this study indicated that supplementation of the macroalgae didnt influence the blood parameters including hemoglobin, hematocrit, white blood cells count and differential WBC counts in Asian sea bass.
