of cage nets and protect juvenile crab was evaluated. At the same time, the impact of illumination and were photophobic: under bright conditions they preferred to in the four corners of the water tank. Under dark conditions, they were randomly distributed. Both bait and the black entice into the cage. The rectangular escape vents at the bottom of the cage net were 4 cm×3 cm, 4.5 cm×3 cm, 5 cm×3 cm and 5.5 cm×3 cm length by height, which corresponded to (the corresponding carapace length with 50% retention) of being 3.75 cm, 4.24 cm, 4.54 cm and 5.08 cm, respectively, and SR (the selection range) being 0.65 cm, 0.45 cm, 0.62 cm and 0.82 cm, respectively. has a linear relationship with the length of the escape vent, being about 92.3% of its length. Based on the minimum carapace length of sexually mature the minimum market-acceptable size standard and the experimental results, we conclude that the most size (
