| Abstract | Thirteen major chapters deal with the following: aquatic macrophytes as fish habitat (spawning, nesting, nursery and feeding habitat, and the significance of structural complexity and density of aquatic macrophytes for fish); fish and other vertebrates of fishery significance that feed on aquatic macrophytes (such as grass carp, several species of tilapia, Colossoma, Puntius, turtles, some birds, manatees, nutria, muskrat); aquatic macrophytes, water quality and fish (includes considerations of the impact of eutrophication and biomanipulation on aquatic macrophytes, wastewater treatment systems, and the impact in temperate climate of intensified fishpond production on aquatic macrophytes); aquatic macrophytes as a link in the food chain (fish grazing impact on nutrient release, and aquatic macrophytes versus phytoplankton, zooplankton, aquatic macroinvertebrates, and crayfish); piscivorous fish - prey relationships in and at the water-aquatic macrophyte interface; invasive and nuisance aquatic plants (water hyacinth, water lettuce, salvinia, papyrus, hydrilla, Myriophyllum) and their impact on fish and fisheries; special floating plant communities, i.e. sudd, varzea and igapo, and their significance for fish stocks and fisheries; inundated forests, submersed trees in reservoirs, and their significance for fish production; the impact of aquatic macrophytes on fish densities, standing crop and production in various types of water bodies; impact of recreation on fish through damage to aquatic plants, and how the recreational fishery is affected by aquatic macrophytes. Further chapters deal with fish capture methods in vegetated water bodies, with the impact of aquatic plant control on fish stocks and fisheries, and with aquatic macrophytes as an obstacle to fishery. The final chapter covers briefly the aspect of aquatic macrophytes as a habitat for vectors and hosts of tropical diseases, and how fish can assist with their control. |
