Present Status for the Reseach and Perspective on Stocking and Cultuer of Ayu (Plecoglossus altiuelis) in China;

Gonadal development of ayu(Plecoglossus altivelis)cultured in ponds was histologically investigated and compared with that in the anandromous and landlocked ayu.

The morphological character istics of Ayu living in Fuxi stream ofChina,in Lake Biwa of Japan and in the Ryukyus of Japan respectively has been studied,the varietal difference among them is outstanding,Of 24 ind-exes beween Ayu living in Fuxi stream of China and those in Lake Biwa of Japan there are 4 outstanding differences and 13 very outstanding diffe-rences.
