Examples of effective porpoise bycatch mitigation in North America
Laetitia Nunny, Ida Carlen, Mark P. Simmonds
A short review is presented here of some of the evidence showing that there is a realistic expectation that bycatch mitigation measures will allow the recovery of cetacean populations. For example, in the Monterey Bay Region, the harbour porpoise population has grown from some 1,486 in 1987 to some 3,760 in 2013, further to a ban on gillnets there. Whilst some care needs to be taken in extrapolating from the situation in the USA to elsewhere in the world, this helps to illustrate that removing the threat from fisheries can aid population recovery.
