Marco Favero and Juan Pablo Seco Pon (Laboratorio Vertebrados, Universidad Nacional de Mar del Plata, Argentina) have published a commentary in the journal Animal Conservation on a feature paper in the same issue by Bronwyn Maree and colleagues.
A response to the commentary, and to that by Charlotte Boyd (click here), by two of the featured paper’s authors has also been published in the same journal issue.
The Favero & Seco Pon commentary concludes:
“Some of these small-scale fleets consist of thousands of boats operating in waters where seabirds range. When the scale of these fleets is taken into account, even very rare (almost undetectable) by-catch events per boat may have a profound effect in some populations. This is an important conservation issue that will challenge seabird scientists and conservationists in the near future.”
In response to the two commentaries, Ross Wanless and Bronwyn Maree consider that “regulations are seldom sufficient, and incentivizing change is a key ingredient to driving widespread change.”
