| 中文摘要: |
| ２００６～２００７年对汉江中下游四大家鱼早期资源进行了调查，并结合１９７７～１９７８年、２００４年汉江中下游的历史调查资料进行分析。研究表明：汉江中下游四大家鱼卵苗径流量下降明显，从２０世纪７０年代末的近５×１０８粒（尾）下降到２００４年以后的不足１×１０８粒（尾），四大家鱼卵苗径流量占鱼类卵苗总径流量的比例也从１９０％下降到了１％以下；产卵场数量减少了１处，产卵场位置也发生了变化。

| 英文摘要: |
| Surveys on reproduction of the four famous Chinese carp were conducted at the middle and lower reaches of Hanjiang River during spawning season from 2006 to 2007. The result shows the current egg production is less than 1×10^8 ind, which had been almost 5 ×10^8 ind. at the end of 1970s; the proportion of the famous Chinese carps is descending 19.0% to 1% of the tatal runoff. According to the calculation of the spawning sites, one of them is eliminated now because of the construction of the Danjiangkou Reservoir, and the location of the others are changed when comparing to the historical data. |
