The average weight of crab seed in the experimental group was 16.20 g/ind., and the average weight of crab seed in the control group was 13.75 g/ind.. Under the same breeding conditions, the average body weight of adult crabs of the breeding line F5 was 19.64% higher than that of the control group, and the average body weight of the crab seed of the breeding line F5 was 17.82% higher than that of the control group.
