| Abstract: | The 5 factors controlling and effecting sexual early-maturing of river crabs were quantatively studied by contrast experiments in this paper, which made the ratio of sexual early-maturing crabs beyond 10% by controlling the 5 factors, and got the better economic benefits. Meanwhile, the inner and outer factors effecting sexual early-maturing of river crabs were analysed and discussed in the paper. |
