中文摘要 | 水电工程的开发对江河道鱼类资源产生了诸多不利影响,在保护和恢复日益增多的濒危鱼类种群的实践中,孕育和逐渐形成了保护水产学。该文对李仙江流域水电开发与流域内珍稀鱼类异鱲、越鳠、软鳍新光唇鱼和暗色唇鱼人工增殖保护实践中的实施效果和存在问题进行了分析。李仙江水电开发与鱼类增殖保护为河流鱼类的增殖保护提供了一个参考模式。但是增殖放流不是简单地一项任务,要保证整个过程得以顺利进行,需要提前进行繁育规划,提前委托,监测和增殖技术研究先行,资源保护与当地经济发展相结合。 |
英文摘要 | Hydroelectric developments can result in a number of negative environmental consequences. Conservation aquaculture is a branch of science derived from conservation and population recovery studies on endangered fishes. Here we discuss the impacts on fishes caused by hydropower projects in Lixianjiang, and evaluate effects and problems on the propagation of Parazacco spilurus, Hemibagrus pluriradiatus, Neolissochilus benasi and Semilabeo obscurus. A successful propagation project includes foraging ecology in fields, pond cultivation, juvenile fish raising, prevention and curing on fish disease, genetic management, artificial releasing and population monitoring. Artificial propagation is the practicable act on genetic intercommunication, preventing population deterioration for fishes in upper and lower reaches of the dam. For long-term planning, fish stocks are not suitable for many kind of fishes, but can prevent fishes from going extinct in the wild. Basic data collection on fish ecology, parent fish hunting, prevention on fish disease are the most important factors on artificial propagation. Strengthening the genetic management of stock population for keeping a higher genetic diversity can increase the success of stock enhancement. The works on Lixianjiang provide a new model for river fish protection. To make sure the complicated project works well, project plans, commission contracts, base line monitoring and techniques on artificial reproduction must be considered early. Last, fishery conservation should be considered alongside location development. |
