Les flottilles de pêche de l'Union Européenne dans le golfe de Gascogne vues du ciel
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Leaute, Jean-pierre.
Regular flights over the Bay of Biscay by the French Customs Air Service, have enabled us to record more precisely, from 1989 to 1995, the geographical locations of French and other European Community (EU) fishing boats. Data showed three main 'metiers' within the Bay of Biscay fishing fleet: French and Spanish bottom trawlers (61 %), French gill-netters and Spanish longliners: More than 80 % of gill-netters worked inside the territorial sea (12 nautical miles) and 60 % of them worked south of Noirmoutier (47 degrees N). Longliners moved according to the seasons, from the edge of the continental shelf to the 50-100 m sounding lines. Since they work at night, only few pelagic trawlers have been recorded (records being made in daylight). The potters, liners...

Les flottilles de pêche dans la mer territoriale du golfe de Gascogne
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Leaute, Jean-pierre.
The regular aerial survey over the Bay of Biscay (France) by the French Custom Air Service enabled us to record precisely in 2001 the geographical positions of French fishing vessels inside the 12 nautical miles of the French Bay of Biscay (from Bay of Audierne to Spanish border). Among the 2396 ships counted in this area, 1810 were identified, corresponding actually to 900 boats since most of them (52 %) were seen several times. These 900 boats referred to 4 different "métiers", i.e. type of fishing activity: most of them (59 %) were bottom trawlers, 28 % gillnetters, 5 % potters and 5 % longliners; those which used another gear were less than 4 %. General characteristics of the 900 ships were identified: tonnage and power were respectively 25 TJB and 185...

Autores: Leaute, Jean-pierre.
To identify and estimate the evolution of use of fishing areas operated by professionals fishing vessels in Pertuis charentais, from 2004 to 2006, 3 surveys (40 aerial census) were carried out between May and October. The connection with the species landed by these vessels, and the link with bottom of the sea operated by them was studied. Landings of sole (Solea solea) and cuttlefish (Sepia officinalis) were specifically studied.
