The invention discloses a soft shell crab production pool having a soft shell crab automatic collection function, which is used for reducing workers required by soft shell crab production so as to reduce the cost. The soft shell crab production pool include a water pool; two ends of the bottom of the water pool are inclined; a sieve plate capable of doing reciprocating slide between the two ends of the water pool is arranged in the water pool; a plurality of sieve holes are formed in the sieve plate, the size of the sieve holes 5 is greater than that of crabs which are just input and is less than that of exuviated crabs; and a clearance between a side edge of the sieve plate and a side wall of the water pool and a clearance between a bottom edge of the sieve plate and the bottom of the water pool are less than 1cm. exuviated soft shell crabs having a large size are caught out of the water pool through the sieve plate, workers do not have to stare at soft shell crabs, the production cost and the working load of the workers can be reduced and lowered, and promotion of soft shell crab production is facilitated.
