Knowing the fishery to know the bycatch: Bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries

Kindt-Larsen, Lotte; Glemarec, Gildas; Berg, Casper W.; Königson, Sara; Kroner, Anne-Mette; Søgaard, Mathias; Lusseau, David
Proceedings of the Royal Society B: Biological Sciences (2023)

Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies…
