Figure 2.

Differences between the mean ML of fish and invertebrate species in fisheries landing in the 1950s, and that in the 1990s, mapped into 180 000 cells of 1/2 latitude/longitude degrees according to the procedure in Watson et al. (2004). Note areas of strong decline (greater than 1 m) around the countries bordering the North Atlantic and other industrialized countries. The distribution of the size reductions shown here largely matches those of the TL, as may be expected given the high correlation between TL and body size (Pauly & Watson 2005).
