We carried out the breeding of crabs in three consecutive years from 1999 to 2001. The breeding seedlings are maintained in ponds for a period of three years, with an average survival rate of 49% in three years, of which the survival rate of seedlings in 2001 was 61%. Through three years of production practice, the technology of raising the survival rate of the shuttle crab pond now is summarized as follows: 1.
