Amazonian urbanization and fishery declines

Interviews with 392 rural Amazonian fishers near Manaus, Brazil indicate that overfishing of the large-bodied keystone fish species tambaqui (Colossoma macropomum) has led to a reduction in tambaqui body size and catch rate in an area extending more than 1,000 km from Manaus; the reduction may be a result of increased access to fish-buyers and ice due to urban demand, according to the authors.
