| Since 1967, albacore fishermen have been involved in the studies on fishery, recording their observations in fishing logbooks. This work is conducted under the authority of the Interprofessional tuna committee and studies have been carried out from 1967 to 1969 driven by the late professor Postel, and then taken over in 1969 by the CNEXO. The fishery is exploited mainly by a fleet of 300 French tuna boats and 1 000 Spanish tuna boats using mobile lines and living bait. It occurs over the summer season, from June in an area comprised between the Gibraltar straight and the Azores Islands until the end of September along the Franco-Irish continental shelf. |

| Treatement of faunistical data collected by sub'marine photography is applied on an infralittoral area of "rade de Brest". Automatic cartography of the most important epibenthic species gives, in a first approach, some precisions on spatial pattern of these organisms : size and density of agregats, connecting or excluding relationships, influences of the bottom characteristics. Statistical analysis of individual distribution of each species by both parametric and non parametric tests completes this cartographic examination and point out different levels of heterogencity at different spatial scale. In a third step a synthesis regrouping all the distributions is given by the two first axis of an inertia analysis. This technique may introduce an attempt to... |
