In shrimp culture ponds,a total of 86 species of protozoa were observed,which included 48 species of ciliates,25 species of mastigophorans and 13 species of amoebas.The protozoa communitiy was dominated by species which move slow and feed on bacteria,detrius,and algae,such as Difflugia avellana,Cyclidium citrullus,Vaginicola crystalline,Stentor polymorphrus and Vorticella sp.The protozoa colonized procedure dynamics characteristics indicated that,compared to two control ponds,the protozoan community in sediment-restored ponds resumed growth quicker;The protozoan species number colonized on the PFU was larger,the density was higher;some ciliates which in favor of entrophic water such as Paramecium caudaium,Paruroleptus spp.appeared later.During the cultivation,compared to the control ponds,the protozoan community in experimental ponds was more steady,the protozoan species number and density had lesser variation,pH and water transparency fluctuated littler,and the water quality was better.
