| 中文摘要: |
| 为了解赤水河的鱼类资源现状,于2010年5～6月和9～10月在赤水河赤水镇、赤水市和合江县的3个江段进行了渔获物调查工作。通过统计各江段的渔业捕捞情况,计算年捕捞量。采用体长股分析的方法,对云南光唇鱼(Acrossocheilus yunanensis)、大鳍鳠(Mystus macropterus)和张氏歺鱼又(Hemiculter tchangi)的资源量进行了估算,并以此推算各江段鱼类的总资源量。结果显示,赤水镇江段的鱼类年总资源量为10.76t,其中云南光唇鱼为1.23t;赤水市江段的年总资源量为51.05t,其中大鳍鳠为8.50t;合江县江段的年总资源量为71.37t,其中张氏歺又鱼为4.39t。估算结果可以为赤水河鱼类资源保护措施的制定提供数据参考。 |

| In May-June and September-October 2010，an investigation of commercial fishing was carried out in Chishui River with the purpose to study the status of fish resources. Based on the fishery statistic data，total fish catchwas estimated. The length-structure VPA method was applied to evaluate the stock size of Acrossocheilus yunanensis，Mystus macropterus and Hemiculter tchangi. The results showed that the biomass of the above three species were 1 .23 tones，8. 50 tones and 4. 39 tones，respectively. The total fish biomass for reaches of Chishui Town，ChishuiCity and Hejiang County were 10.76 tones，51.05 tones and 71.37 tones，respectively. The results may provide information for assessing protection potentialities and developing conservation strategies. |
