The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…
To ping or not to ping: The use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries
Dawson, S. M.; Northridge, S.; Waples, D.; Read, A. J.
Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
