外文摘要：In this study, we formulated five diets, namely, P1, P2, P3, P4 and P5, with Chlorella sp. powder, Spirulina platensis powder, yeast powder, soybean meal and corn gluten, respectively, as major protein sources. A feeding experiment was designed to evaluate the effects of formulated diets on the growth performance, immunity and antioxidant and biomineralization capacity of juvenile pearl oyster (Pinctada fucata martensii). In the experiments, the five groups were separately fed with P1, P2, P3, P4 and P5 diets. After 45 days of feeding, pearl oysters fed on P1, P2, P3 and P4 diets showed significantly higher absolute growth rate and protease and amylase activities than those fed on P5 diet (P < 0.05). Moreover, pearl oysters fed on P1, P2, P3 and P4 diets exhibited significantly higher activities of alkaline phosphatase (AKP), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) (P < 0.05). Significantly higher expression levels of SOD, GPx, CAT, heat shock protein (HSP) 70, HSP90, nacrein, pif177 and pearlin mRNA were observed in pearl oysters fed on P1, P2, P3 and P4 diets relative to those fed on P5 (P < 0.05). Results suggested the suitability of Chlorella sp. powder, S. platensis powder, yeast powder and soybean meal as protein sources for development of formulated diets for pearl oyster P. f. martensii.
