Abstract

Incidental mortality of dolphins in the E tropical Pacific caused by the tuna fishery has probably been sufficient to affect abundance of stocks of spotted dolphin Stenella attenuata, spinner dolphin S. longirostris and common dolphin Delphinus delphis. There is little evidence of trends in population size in recent years, as determined by five-year tests for trend. -from Authors
