浅议“灯光诱捕”在跋山水库渔业生产中的应用

The application of"ensnare by lighting"in fishery production in Bashan reservoir

山东省沂水县跋山水库位于沂河干流中上游,是一座集灌溉、防洪、发电、养殖为一体的国家大型水利工程。近几年由于县政府倡导库区村民搞网箱养鱼,库区村民养鱼热情高涨,养鱼网箱急剧增多。由于库内网箱多,常规捕捞效果不佳,回捕率不到30%,为此,作者结合水库捕捞难度大、回捕率低的现状,根据积累的多年经验,介绍了水库灯光诱捕的原理、网箱结构、操作及注意的问题,指出灯光诱捕对挖掘水库渔业资源潜力、提高水库经济效益、开展大水面捕捞、提高回捕率的意义。

The Bashan reservoir of Yishui county of Shandong province is a state irrigation works project gathering with irrigation, preventing flood, generating electricity and aquaculture. In recent years, fish farming in net-cage has been greatly increased. However, due to over loaded net-cages, the effect of normal capture is not good, the capture rate is less than 30%. Therefore, the author introduced the theory of ＂ensnare by lighting＂ in the reservoir, structure of net-cages and its operations, etc. The author indicated that ＂ensnare by lighting＂ can be used for digging fishery resources potential of the reservoir, increasing economic benefit of the reservoir, developing capture level in big water areas and increasing the capture rate.
