摘要This study aimed at evaluating the ploidy effects on growth performances of Chinese shrimp (Fenneropenaeus chinensis Osbeck, 1765) reared in different salinities under laboratory conditions. In the acute salinity experiment, there was no difference (P > 0.05) in tolerance observed in triploid and diploid shrimp due to abrupt salinity changes. The lethal salinity for 50% of the individuals in 96 h at 23-25 degrees C was about 2 g L(-1) in both triploids and diploids. While for the chronic salinity experiment, statistical analyses confirmed that the differences in growth performances including the specific growth rate (SGR), the feeding rate (FR), feed conversion efficiency (FCE) and intermoult period (IP) between triploid and diploid were related to salinity. Diploid shrimp reared in 20 g L(-1) exhibited highest SGR (P < 0.05), while triploids performed well in 20 and 30 g L(-1) salinities (P < 0.05). Based on the survival and growth data, the optimal salinity for the culture of diploid F. chinensis should be 20 g L(-1) and for triploids it should be between 20 and 30 g L(-1).; This study aimed at evaluating the ploidy effects on growth performances of Chinese shrimp (Fenneropenaeus chinensis Osbeck, 1765) reared in different salinities under laboratory conditions.
