Qingdao Fishery Technology Sp read Station, Qingdao 266000, China) Received : Nov., 29, 2007 Key words : barfin flounder (V eras per moseri) ; immune organ ; head kidney ; melano2macrophage centers Abstract : A histological examination was made on t he ontogenetic develop ment of immune organs ( thy2 mus, kidney and spleen) f rom hatching to t he 60th day after hatching (DA H) in barfin flounder. The se2 quences of appearance of t he immune organsπ anlage were kidney, spleen and t hymus, similar to t ho se of ot her marine teleo st s previously documented. The first f unctional lymp hoid organ was head kidney, differ2 ent from t hat of ot her marine teleost s : t hymus was t he first lymp hoid organ normally. During t he larval pe2 riod, t he head kidney and t hymus were always closed wit h each ot her, but t he cell bridge was not apparent. During t he posterior develop mental period of the immune organs, the melano2macrop hage centers (MMCs) were seen in all t he t hree immune organs, also including the t hymus, alt hough the struct ure and abundance are different within t hem. Through t he study on immune organs in barfin flounder, we could have a basic acquaintanceship wit h the ontogeny, mat uration and it s characteristics of immune organs. And all data from t his st udy would provide a theoretical basis of t he f urther intensive aquacult ure of t he barfin flounder as well as t he applicatio n of artificial vaccine. ( : ) 92
