Since 2017, a national working group, co-piloted by the ministries responsible for fisheries and the environment, made up of fisheries professionals, scientists and managers, has been working on this issue. Its main objective is the exchange of information; and the monitoring of the different programmes implemented to acquire knowledge on dolphin populations, catches or means of mitigation.
The LICADO programme aiming at finding ways to reduce common dolphin catches started in 2019, financed within the framework of the FEAMP (European Fund for Maritime Affairs and Fisheries) and supported by the CNPMEM. This project aims, on the one hand, to develop new acoustic repellent systems and, on the other hand, to reflect on avoidance practices and strategies for the net trade.
The use of certain models of acoustic repellents may be part of the response to by-catches in the pelagic trawl sector. The resumption of tests at sea during the winter of 2018 on 3 pairs of trawlers seems encouraging, but the effectiveness on a fleet scale has yet to be validated (PIC project, supported by the producers’ organisation Pêcheurs de Bretagne). For the net trade, there is still no known and reliable technological way of reducing catches, and the use of acoustic repellents is not operationally or ecologically feasible in the fishery.
For the net trade, there is as yet no known and reliable technology to reduce catches, and the use of acoustic repellents is not operationally or ecologically feasible in this context (significant deployment, large exclusion zone and ineffectiveness of commercial models on nets).
