Pair trawling is a fishing activity carried out by two boats, with one towing each warp (the towing cables). As the mouth of the net is kept open by the lateral pull of the individual vessels, otter boards are not required. With the towing power of two boats and no otter boards, a larger net may be worked than would otherwise be possible, or alternatively, the two boats can share increased fuel efficiency.

  • Le chalut-bœuf (Pair trawling pour les anglophones) est traîné par deux bateaux. La manœuvre en est plus délicate mais il permet d'avoir de très gros chaluts dont la gueule est bien plus largement ouverte. Les chalutiers embarquent alternativement les prises. Ils sont par exemple utilisés par les pêcheurs de la Turballe et de Saint-Jean-de-Luz en France ou dans les pays scandinaves. C'est le mode de pêche qui capture le plus de cétacés en Manche où il est utilisé pour la pêche au bar. Seul le Royaume-Uni a assuré un suivi indépendant, sur plusieurs années, des prises de cétacés par chalut en bœuf, démontrant un niveau des prises accessoires dépassant les seuils critiques pour le chalutage pélagique en bœuf en Manche. Lors de la saison 2003/2004, 169 dauphins communs ont ainsi été tués dans les chaluts (bœufs) anglais de cette zone (pour un total estimé de 439 dauphins pris pour tout le Royaume-Uni cette année-là). La France assurant environ 5/6 de cette pêche, une extrapolation des taux de prises anglais donnerait un total d'environ 2600 animaux tués en un an en France. Sur ces bases, le gouvernement britannique a demandé en 2004 la fermeture de cette pêche (en mesures d'urgence de la PCE). Cette demande a été refusée par l'UE. En 2008, un rapport de l'Ifremer conclut à des captures accidentelles de cétacés de l'ordre de 400 individus par an pour le chalutage pélagique en bœuf. Ce chalutage est particulièrement efficace sur les espèces démersales. Dans les eaux, où le bruit d'un seul navire peut disperser les poissons, deux navires avançant de concert tendent à rabattre le poisson dans l'axe du filet, permettant des captures souvent considérablement supérieures à celles atteintes par le chalutage de fond. Le chalutage en bœuf ciblant COD (cabillaud) au large de la côte de la Nouvelle-Angleterre a rapporté en moyenne par navire de pêche, des captures de trois à six fois plus élevées qu'avec des chaluts simples.

  • Pair trawling is a fishing activity carried out by two boats, with one towing each warp (the towing cables). As the mouth of the net is kept open by the lateral pull of the individual vessels, otter boards are not required. With the towing power of two boats and no otter boards, a larger net may be worked than would otherwise be possible, or alternatively, the two boats can share increased fuel efficiency. As doors are not necessary, the gear arrangements are simplified, with the warps attaching directly to the wings of the net. Setting and hauling of the nets are carried out by one boat, while the other is only used for towing; usually each will take turns at these operations. Pair trawling is effective on all demersal species. In shallow waters, where the noise from a single vessel may scatter fish, two vessels operating a distance apart tend to herd fish into the path of the net. Catch per vessel often considerably exceeds that attainable through standard bottom trawling. Pair trawlers targeting cod off the coast of New England have reported average per vessel catches of three to six times that from single trawls. Because of the increased efficiency of pair trawling, vessels are able to tow their gears in mid-water at a faster speed to target species which are normally able to escape trawl nets, such as the European seabass. This has caused some controversy, due to the high level of marine mammal bycatch associated, leading to the British government introducing a ban on pair trawling for bass in UK territorial waters.
