This work is divided into 4 parts. First, in a broad introduction, a short history is given on albacore fishing in the bay of Biscay from its origin until its present extension in the neighbourhood of the Acores. This is followed by a history of the research beginning with the first attempts at classifying the albacore and then with the first investigations done on research ships; then the authors explain the reasons and the evolution of their work with reference to what was already known. The 2nd part of the study describes the campaigns of research from 1967 to 1972 to study the albacore in the north east Atlantic and the fishing and prospecting techniques used during these campaigns. The 3rd part of this investigation shows the research works sensu... |

Les résultats encourageants obtenus au cours de la campagne du thon pendant l'été 1967, dans le golfe de Gascogne et sur la bordure cantabrique (1), nous ont conduits à élargir cette annee nos investigations sur une aire étendue vers le S au large du Portugal et vers le N au secteur SO de l'Irlande. Le but principal de l'opération était d'étudier la répartition et les migrations du germon depuis le printemps jusqu'au début de l'automne et accessoirement de faire quelques observations sur le thon rouge et les autres espèces qui pourraient être rencontrées. Ce programme a pu être réalisé au cours de deux campagnes qui ont eu lieu du 18 mai au 5 juillet, "avec la Pelagia" et du 19 août au 30 septembre, avec la "Thalassa" et "la Pelagia" travaillant... |

As a result of 5 years of sampling the following results were reached: (1) so far as growth was concerned 3 size groups were recognised during June-July. The `classic' type measuring similar to 52-62 cm, a group ranging from 54-55 cm and a 3rd group measuring 64-65cm. By marking the fish and by studying the degree of distribution of the stomach parasite, H.fusca it was noted that the albacore entering the north east Atlantic during summer constitute a heterogenous population migrate along the same route upto the north west boundary of Cape Finisterre. Thereafter they diverge, one group forming a semi-circle along the Bay of Biscay, another moving northwards and on reaching the south of Ireland bends westward. |
