N2 - The endangered endemic fish Ameca splendens was surveyed monthly from June 2001 to May 2002 at two sites in the upper Rio Ameca basin. Both populations demonstrated two annual reproduction peaks, with one in the spring season and the other in late fall. The condition and gonadosomatic index were higher in the population from the upstream pristine environment. Those fish in the pollution-stressed downstream region attained greater body length, longevity, and fecundity.
