Abstract

The effect different levels of astaxanthin on growth indices, food conversion ratio, immune system and antioxidant capacity of farmed female Huso huso broodstock was investigated.12 Huso huso (pre brood stock female, sexual maturation = II, average weight and length=16.16 kg ± 0.16 and 140.65 ± 13.2 cm) were fed by diet containing 50% protein, 14% lipid and 18 MJ/kg energy in Four treatments:C (without astaxanthin), C50, C100, C150 and C200 (50, 100, 150 and 200 mg/kg of astaxanthin) for 674 days.At the end of the breeding period, fish were in sexual stage III to IV and IV. fish fed with C200 had the highest final weight, body weight gain percentage, specific growth rate and the lowest food conversion ratio (P<0.05). lysozyme and immunoglobulin M in fish fed with C150 and C200 diets was significant higher than other treatments(P<0.05). Complement were increased by increasing of astaxanthin diet and highest Complement was recorded in fish fed C200 (P<0.05). total immunoglobulin in fish fed C100, C150 and C200 was significantly higher than C50 and C (P<0.05). A significant increase in superoxide dismutase (SOD), catalase (CAT) were revealed by increasing astaxanthin in diet, and highest amount was recorded in the fish fed by C200, while malondialdehyde (MDA) was opposite relationship with astaxanthin diet (P<0.05). The results of this study was revealed that a 200 mg/kg astaxanthin supplemetation led to growth indices increasing and improving immune system antioxidant capacity in Huso huso for brood stock stage.
