Ecology of Arapaima spp.
Arapaima spp. are giant, obligate air-breathing fishes of high economic value in the Amazon Basin. Lack of studies, poor management, and intense fishing pressure have led to widespread overexploitation of arapaima, making it necessary to better understand their biology and ecology in order to promote their conservation.
Fish resources worldwide are under growing pressures. Although the status of fish resources is well-studied in the temperate developed world, they are under-studied in the tropical developing world, where data scarcity, species diversity, and the fastest growing pressures often require alternative assessment approaches.
Freshwater ecosystems are among the most altered systems on earth. Widespread changes in the hydrology and vegetation cover of freshwater ecosystems are known to influence fish communities, but their impacts on fisheries production remain uncertain.
Fisheries worldwide are in need of new management approaches. Participation of fishers and consideration of ecosystem structure are increasingly recognized as necessary for fisheries conservation, but both strategies still need further development and integration with current management systems.
