| Abstract: | During the test period of 1998,44 brood crabs of mud crab(Scylla serrata) were used, 62.5milliom zoeas ( Z1 ) and 4.0976 million megalopas were obtained; the average seed production was 6180/m2 ,and average survival rate was 6. 56% . The obtained megaiopas were then used to produce young crabs, and 2.244 million young crabs were obtained. The average carapace width and weight of the young crabs were 1.17cm and 0.22g respectively, the average young crab production and survival rate were 441.26%/m2 and 56.6% respectively. Good economic benefit was acquired. |
