| 摘 要： | 通过2004年3个时间段对洪湖5个取样点鱼类资源的调查分析，结合历史资料，结果有：共记录到鱼类42种，隶属6目11科；以鲫、黄颡鱼、餐条和红鲌为优势种，草鱼、鲶、鳜、乌鳢等较大型鱼类在数量上呈下降趋势；对鲤、鲫的年龄组成分析表明种群呈低龄化趋势。针对鱼类资源的现状，对影响因素进行了初步评价，并提出保护建议。 |

| Abstract: | Fish resources of Honghu lake were surveyed by collecting samples from 5 sites of the lake during three time periods in 2004.In reference with historical data,42 species were recorded,belonging to 6 orders 11 families,with Carassius auratus auratus,Pseudobagrus fulvidraco,Hemiculter leucisculus,and Cultrichthys erythropteru,as dominant species,while population number of Ctenopharyngodon idellus,Parasilurus asotus,Siniperca chuatsi,and Ophiiocephalus argus were in a decreasing strend;age composition analysis showed that low aged fishes of Cyprinus(cprinus)carpi and,Carassius auratus auratus were increasing in number.Factors influencing the present status of fish resources were analyzed and conservation strategy were discussed. |
