Natural history of the flood fishes,y, and the ecosystem — if its natural history is to be understood in the broadest terms. The high diversity of the Amazon fish fauna, and lack of sound taxonomical studies for most groups, make the study of communities very difficult in the present state of knowledge. My own approach has been to tak

Problems and prospects,work of the economic development of the Amazon basin. Of most importance will be the degree to which the floodplains are deforested for agricultural schemes; large-scale deforestation would probably destroy the fisheries as they are presently known. Other economic decisions that will affect the fish

Affluence

Physical and biological portrait of the Rio Madeira basin,mated to be on the order of 1.4 trillion m. per year (Hidrologia 1975–1979). The Rio Madeira’s annual volume is about twice that of the Mississippi’s and nearly equal to that of Africa’s largest river, the Zaire (Fig. 1.2).

HILAR

Natural history of the flood fishes,m — and a constant and intensive fishing effort directed towards them helps reveal many ecological patterns, and especially migratory behavior. Before discussing each of the food fish species in detail, I will first present an overview of what is known about their migratory and feeding behavior in relation to the Rio Madeira as a system.
