中国对虾育苗池和养成池微型污着生物群落的研究

于１９９２年４－１０月在山东省青岛市黄岛前湾育苗场和胶南市红石崖镇邵家村养殖场，采用载玻片挂片和对中国对虾现场取样的方法，研究中国对虾育苗池和养成池载玻片挂 表面和对体表微型污着生物群落的组成和发展。

STUDIES ON THE MICROFOULING COMMUNITIES FROM THE LARVAL REARING TANKS AND THE GROWOUT PONDS OF PENAEUS CHINENSIS

Studies on the components and development of the ndcrofoulingconrmunities on the glass surfaees of the larval rearing tanks, and the growout pondsof Penaeus chinenesis at Jiaozhou Bay in China were carried out in 1992 The studies showed attaching organisms on the surfaces of test panels were bacteria, fungi, algae and protozoa; the microfouling organisms on the panels of the larval rearing tanks were cominonly bacteria, fungi and ciliates; algae such as Licmo Phora sp appeared occasionally The composition of Ancrofouling communitiesat all depths was similar In the growout ponds, the conunuinities consist of bacteria,fungi, algae and ciliates The ndcrofouling organisms on the panels at differeflt depthswere slightly different: at the upper layer of the ponds (0- 50cm), the attachingorgamsms were bacteria, algae and ciliates; at the median layer (50- 10cm) thatwere mostly bacteria, ciliates and less of fungi and algae; at the lower layer(100- 150cm) that were bacteria, fungi and ciliates, and rarely algae. The developnlent of the community began with attachment of bacteria to thesurface, followed by other attaching ndcroorganisms (fungi, algae and ciliates). Thebacteria, together with free living ndcroorganisms (including unicellular microalgae,ameba, flagellata, cilliates, nematodes, rotifers, etc.) formed a slime film The slimefilm formed on the larval tanks can keep in a larval rearing cycle, but that formed inthe growout ponds could be replace by microorganisms including hydroids, bryozoaand barnacles. The composition and the developmental process of the microfoulingcommunities on the panels and the body surfaces of shrimps are similar. It issugg Csted that there is a phoresis relation between peneid shrimp and microfoulingorgamsms.
