排水灌溉用的闸口、涵洞,一般不大引起钓鱼人的注意,认为这样的地方没什么鱼可钓。其实,不少涵洞外接河道,内连纵横交错的渠道与星罗棋布的湖泊、池塘,这样的涵洞是鲶鱼栖身的好场所,在这些地方夜钓鲶鱼,一般都能有好收获。 Drainage irrigation gates, culverts, generally not cause much attention of anglers, that such a place no fish to catch. In fact, many culverts outside the river, even criss-cross channels and dotted with lakes, ponds, such a cul-de-sac is a good place for catfish to live in these places, night fishing catfish, generally can have a good harvest.
