FIG. 1. Map showing latent marine fishery resources (fish stocks believed to be underfished in 1949). Circled stocks are those now
certainly or probably in need of management (the " pilchard " off the west coast of South America presumably refers to the
anchoveta stock). Of the tunas, the yellowfin is probably heavily exploited in all areas, but further expansion may be possible for
other species such as skipjack or bonito. (From United Nations, 1931.)
