A pinger experiment was carried out on the French trammel net fishery in the marine protected area off the west coasts of Britanny in order to compare acoustic mitigation measures for harbour porpoise. 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...

Up to now there has been no strong investigation on by-catch of marine mammals in the French set net fisheries of the English Channel (ICES areas VIIe,d &amp; IVc) as the EC 812/2004 Regulation does not oblige the state members to put observers on board of vessels in the ICES area VII. A study named FilManCet has been started end 2008-beginning 2009 to focus on the by-catch occurring on the set net vessels (whatever the hull length is) issued from Boulogne and Dunkerque ports (fisheries in VIId&amp;IVc) and also from several ports of North of Brittany. In this study which is conducted by the Fishing Industry, the data are made available to the scientists of Ifremer who has prepared also the sampling scheme for observation at sea. Two observers are employed...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Bree, P.J.H. van; Bosscha Erdbrink, D.P.
The fortuitous discovery, in the collections of the National Museum of Natural History at Leiden, of a probably subfossil right half-mandible of a Grey Seal is reported. A short description of the piece is given and it is compared with some other recent, subfossil and fossil material.
