Preliminary studies on the salinity tolerance of “Huangxuan No.1” Portunus trituberculatus
摘要
Abstract
The salinity tolerance of "Huangxuan No.1" Portunus trituberculatus was investigated in controlled temporary water by including sudden and gradual changes in salinity.The results showed that the LD50 values of crab larvae at Stage II for 24h,48h,72h tolerance to low-salinity were 21.655,22.109,23.184,respectively,and for tolerance to high-salinity were 50.711,50.061,49.612 respectively.The LD50 values of 80-day crabs for 24,48,72h tolerance to low-salinity were 5.13,7.49,8.5 6,respectively,and for tolerance to high-salinity were 54.49,52.74,52.21 respectively.Crab larvae at Stage II can survive in 6.7 low-salinity water by gradual salinity decrease,and can survive in 47.7 high-salinity water by gradual salinity increase.While 80-day crabs can survive in 5.7 low-salinity water by gradual salinity decrease,and can survive in 47.7 high-salinity water by gradual salinity increase.Therefore,"Huangxuan No.1" P.trituberculatus has a strong salinity tolerability.关键词
