%X The effect of solutions with different concentrations of EM bacteria(effective microorganisms) on physicochemical factors of sea cucumber culture water was studied by using indoor test and pond test.The test results showed that:EM bacteria had no significant effect on total dissolved solids(TDS) and conductivity(P>0.05);could gravely increase oxidation-reduction potential(ORP),dissolved oxygen(DO) and transparency(P<0.05).The effect of Ⅳ group(bacterial concentration 4×109 cfu/m3) was the best one,ORP and DO in test chanber with the average increase 3.39% and 26.20% respectively;ORP,DO and transparency in test pool average increased by 8.38%,18.58% and 54.69% restectively.The pH values in each test chamber descended slowly,without significant differences(P>0.05),and pH in test pool dropped 3.94% lower than that in the control pool on average,falling within suitable scopes,with the average pH value 7.79 in the test pool.
