Methods for high production breeding, brood crab culture, seedling setting and larva culture, were studied. The key step was to decrease seawater density gradually to 1.014 at the stage of larva and brood crab culture. The water for offspring setting was sterilized with NaCLO and then neutralized with NaS2O3. The larva density in the pond was set to about 200,000/m3. At this stage the unicellular algae concentration was about 300,00-400,000cell/ml(diatom) and 80,000cell/ml (platymonas spp.) From then on, different antibiotics were used (terramycin, Chloramphenicol Weidao in turn) every day. The brood crabs were cultured in ponds at the intertidal zone or in culture area shallow waters, so that the embryo development. This experiment-yielded are effective way to delay embryo development. The output in megalopa larva was about 700kg in 1200m3 water and production per cubic meten water was 0.59kg/m3. The survial rate from acanthosoma to mega lopa larva reached 31.4%.
