The waters off northeastern South America support the large Guianas-Brazil shrimp fishery. Thirteen fishing zones were established for these waters by shrimping interests to identify the general location of shrimp catches and production. In this paper, the 13 fishing zones are subdivided into 65 depth zones, their areas calculated from nautical charts, and presented in tabular form. The sea surface area of the 13 fishing zones covers 217,392 nmi² (746,308 km²). Forty percent of this area is over the continental shelf and 60 percent over water deeper than 100 fm (183 m); only 13 percent of the total area is trawled for shrimp. Areas calculated by depth zones will be ov value for estimating fish population density and catch per unit of effort by unit area.
