This document presents the results of a study on the impact of the french albacore tuna drift net fishery, mainly at the dolphins population level. Data collected during two embarked observers campains in 1992 and 1993 and the results of a sighting survey in 1993 give an estimation of the population size of common and striped dolphins (61 888 and 73 843) and mean values of ratio fishing of mortality (0.7 and 1.6%). A model was built in order to simulate the effect of the 5% upper limits of fishing mortality (1.5 and 3%). These values would leed to an annual rate of decrease of -1 %. It is unlikely that such values would jeopardize the survival and the presence of these species. Total incidental catches represent 15% of these total catch; albacore tuna...

The GERMON project had several aims i) to understand the populations’ structure between albacore tuna southwest of the Indian Ocean and southeast Atlantic, ii) to determine the origin of juveniles observed in South Africa iii) to improve the understanding of the biology field (Size/Size and Size/Weight; reproduction and feeding area; trophic linkages) and iv) to initiate work on chemical analyzes and adaptation of the albacore species to its environment. These aims have been held and the results allow a better understanding of the management albacore. A general summary of results is presented in Part 9.

Essais de pêche du germon au chalut-boeuf pélagique du 31 août au 14 septembre 87
Provedor de dados: 5
Autores: George, Jean-paul.
Trials of albacore tuna fishing using pelagic pair trawling took place in the month of September 1987 with trawlers of the Lorient-Etel region. The good results obtained should make possible a renaissance of the French tuna fleet, on the decline for several years now.
