A PLATAFORMA CONTINENTAL BRASILEIRA E SUA RELAÇÃO COM A ZONA COSTEIRA E A PESCA (the Brazilian continental shelf and its relation with the coastal zone and fishing)
A plataforma continental brasileira, com cerca de 8.000 km, engloba diversas zonas climáticas expressas no aporte diferenciado de cargas sólida e líquida. Com exceção dos vultosos aportes de sedimentos e nutrientes dos sistemas Amazonas ao norte e do Prata, ao sul, no restante da plataforma predomina a baixa produtividade devido à reduzida disponibilidade de nutrientes. Considerando a morfologia do fundo e apetrecho de pesca, pode-se dividir a plataforma em duas regiões: a norte do cabo Frio, com águas quentes, fundo irregular e carbonático, onde predomina a pesca por meio de espinhel e covos; e a sudoeste do cabo Frio, com águas frias, fundo liso e predomínio da pesca por rede.
Palavras chave: Plataforma continental, Pesca, Brasil.
The Brazilian continental shelf, with about 8.000 km length, includes several climatic zones expressed in differentiated solid and liquid sediment input. Excepting the important input of sediments and nutrients from the Amazon in the North and the Prata in the South the rest of the shelf is characterized by low productivity due the reduced availability of nutrients. Considering the morphology of the bottom and fishing equipment, the shelf can be divided into two regions: north of Cabo Frio, with warm waters, irregular carbonate bottom, with fishery predominantly through long line and traps; and Southwest of Cabo Frio, with cold waters, flat bottom and fishery predominantly through fishing nets.
Key Words: Continental shelf, Fishing , Brazil.
