| 摘 要： | １９９１年６月至１９９３年４月测得监利老江河浮游植物初级毛生产量年平均为（Ｏ２）１．５６ｇ／ｍ２·ｄ－１，年平均总毛生产量为１０４９７ｔ氧；鱼类生长期（４～１０月）浮游植物初级毛生产量平均为（Ｏ２）２．１７ｇ／ｍ２·ｄ－１，４～１０月总毛生产量为８３８５ｔ氧，占年总毛生产量的７９．８８％。水温、透明度和氮、磷营养元素是影响老江河浮游植物初级生产力的主要因素。经过估算，监利老江河四大家鱼种质资源天然生态库鲢鳙鱼产力为１３２．９ｔ左右。

| 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. |
