Predicting the population‐level impact of mitigating harbor porpoise bycatch with pingers and time‐area fishing closures

Ecosphere, 2017
Unintentional mortality of higher trophic‐level species in commercial fisheries (bycatch) represents a major conservation concern as it may influence the long‐term persistence of populations.

The effects of visual impediment on the approaching behavior of harbor porpoise, Phocoena phocoena [PDF]

, 2019
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise (Phocoena phocoena). When a porpoise approached

An investigation of factors related to the bycatch of small cetaceans in fishing gear

, 2011
The bycatch of cetaceans in fishing gear is considered to be one of the biggest conservation threats to these species. Gear modifications have the potential to reduce these bycatches in global fisheries but there is little available information on how ...
