Three types of pinger devices (Aquamark 100, Pinger V02, DDD02) were used for porpoise mitigation in the area where no bycatch estimation has previously been made. The pingers DDD02 were attached at each end of the net near the anchor. The pinger Aquamark and pinger V02 were attached to the headline of the nets and were spaced by 400 m and 200 m respectively. The EC regulation 812/2004 requires a such pilot study. Observers at sea were deployed on board of 10 fishing vessels from Le Conquet and Audierne harbours. During one year, 462 km of control nets (non... |
