Incidental capture of the short-beaked common dolphin (Delphinus delphis) in the industrial purse seine fishery in northern Chile
Incidental capture of marine mammals during fishing activities is a worldwide concern given the potentially drastic effects this can have on marine mammal populations. To assess the interaction between marine mammals and industrial fishery, an onboard observer monitored 8 purse seine fishing trips i...
