I. The experiment results of vertical channel module formeretrix lusoriaandrudittapes variegateculture under shade in the 30 days. Themeretrix lusoriaand a r udittapes variegateaverage shell length and the average weight was increase 26.79% and 112.5%, 13.65% and 67.04% ,respectively. Showing light does not affect its growth. Second, therudittapes variegatedifferent stocking density ( 200,300.400,500 Individual / square meter) culture 40 days, the initial average shell was 22.61mm and the average weight was 1.86g. The200 Individual / square meter which average shell length and the average weight grew by 21.03% and 111.36% respectively. The 300 Individual /m2 which is increase 21.14% and 111.36%, respectively, and the 400 Individual /m2 is crease 24.62% and 129.5%, respectively. and the 500 Individual /m2 is crease 24.30% and 128.41%, respectively. The density effect is still not obvious at present. Third, the flow of water on the adult monomer oyster grew effect after 8 weeks, the four groups of fatness were 3.13 ± 0.15%; 5.16 ± 0.69%; 3.09% 0.49% and the control group 5.78 ± 0.80%. The weight gain was 1.26 g; 1.65 g; 1.04 g and 6.81 g of the control group. Fourth, the effect of serial flow on the survival of oysters, the average death rate in parallel mode is 4.7%, the mortality in tandem mode, the upper layer 8.57% middle layer 31.43% lower layer 45.71% different with water exchange rate.
