The higher water plants of the downstream of Amudarya river are described in the article. Higher water plants execute very important functions in any reservoirs. Many plants are a feed for herbivorous fishes. Other plants sprouting on the surface of reservoirs or under water are substrate for spawning of phytophilous fishes. The study of natural forage resources will give in future an opportunity of growing of herbivorous fishes in the fishery reservoirs of the river-delta zone of the Amudarya river.
