【Abstract】 Although so far as the form is concerned, N. pseudotaihuensis is very similar to N. taihuensis, the results of this study showed that their viscid threads of egg cells, ratio of length of pneumatic duct to length of gas bladder, ratio of breadth of branchiostegal ray to total length and spawning populations are significantly different. Therefore N. pseudotaihuensis and N. taihuensis belong to two effective species.更多还原
