It is always used to delineate reserves, as separate from structure. The energy density of Eriocheir sinensis was studied through DEB software in this paper. The results showed that Hepatopancreas energy density （32.17 ± 3.77 KJ/g） was higher than gonad （23.19 ± 2.86KJ/ g）, muscle （24.41± 1.41 K J/g） and carapace energy density （14.42 ±1.76 KJ/g）. The difference between gonad （23.19± 2.86KJ/g） and muscle energy density （4.41 ±1.41 K J/g） of females and males was significant （P 〈 0.01）, but not between muscle and carapace energy density （P 〉 0.05）, and no difference between female and male individual in total energy （P = 0.887） at the stable stage. The linear relation between volume and weight of Eriocheir sinensis was gained by using regression analysis, V=6.104＋ 1.117WW （R2=0.973, n=98）, and the linear relation between total energy and dry weight was also gained, E= 18.12DW-28.05 （R2=0.962 ,n=24）.展开更多

The results showed that after 45-d culture, the crab number per kilogram reached about 300 with survival rate of about 20%; the initial stocking density had significantly effect on the body size of E. sinensis on sell, instead on the survival rate of E. sinensis larvae. Therefore, it is feasible to conduct the culture of E. sinensis larvae in a pool in greenhouse.展开更多
