水生植物（包括维管束植物和浮游植物）和渔业关系密切，它既是草食性和杂食性鱼类的饵料之一，也是多数鱼类栖和产卵场所。本文调查研究了重庆市１４条主要江河的７８种常见水生维管束植物的种类及其分布情况，对重庆市发展江河渔业有一定参考意义。 Aquatic plants (including vascular plants and phytoplankton) are closely linked to fisheries. They are both bait for herbivorous and omnivorous fish and are habitat and spawning grounds for most fish. This paper investigates the species and distribution of 78 species of aquatic vascular plants in 14 major rivers in Chongqing and provides some reference for the development of rivers and fisheries in Chongqing.
