| 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. |

| As part of a general oceanological programme zooplankton samples were collected over a period of 6 years, at least weekly, from a wharf off Pointe-Noire (4°49.2'S; 11°50.3'E).This paper provides a description of the zooplankton seasonal cycle, with special emphasis on the relationships with hydrology. Considering an average year, on a weekly basis, its first aim is to summarize the main features of the similarities and dissimilarities between the weeks of this average cycle.The second aim is to relate these features to different taxa.The paper concludes with a study of annual peculiarities. Mathematical data processing is used to achieve these ends.In addition to its concern with plankton, the paper has a methodological aspect, related to the use of... |
