    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 dam age 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. This publication does not cover inte rrelationships between fish and mangroves, fish in salt marshes and tidal flats, use of aquatic macrophytes as food or fish feed additives in aquaculture, fish in ricefields, use of macrophytes for the removal of aquaculture effluents and in recirculating fish culture systems. Several topics are covered only briefly: water-borne disease control (only those larvivorous and molluscivorous fish, which also serve as food, are discussed); biomanipulation (the section dealing with this subject focuses largely on the function of fish versus macrophytes); floodplains (the reader is directed to major publications on this topic). Control of aquatic macrophytes is limited to the use of fish, and to the impact on fish of chemical and mechanical control measures.

    An updated world review of interactions between marine mammals and fisheries 1991
    Also available in:

    Recent information on marine mammal - fishery interactions is reviewed. A species by species approach is taken for each of the major marine fishing areas of the world. Most recent studies have been devoted to the accidental entanglement or mortality of marine mammals in fishing operations. Several species or populations of marine mammal may be threatened with extinction or severe depletion from such interactions. Most of the fisheries involved are gillnet fisheries. Relatively few recent studies have addressed the possible competitive interactions between marine mammals and fisheries for food and fishery resources.

    World reviews of interactions between marine mammals and fisheries 1984
    Also available in:

    This report summarizes the available information on the distribution, abundance and feeding habits of cetacean, pinniped and sirenian mammals, as well as the information on interactions between these species and fisheries throughout the world. A catalogue of marine mammal species, their population sizes, distributions and diets, is followed by an area by area account of marine mammals, fisheries, and their interactions.
