| At the end of the seventies, as fishing abundance (based on Catch Per Unit Effort) in crabs and lobster fishery steadily declined, operating expenses increased, and fishing boats changed strategy (changing metiers, covering larger distance to fishing areas, fishing seasons being extended, ...) professionals and scientists aimed to consider reinforcing management measures. To enlighten and support potential related decisions, the Comité Régional des Pêches et Cultures Marines de Bretagne (Regional Committee for fishing and farming in Brittany), together with the ISTPM (Ifremer since 1984), conducted a survey on the exploited populations and gave a review of the involved Breton fleet. This report shows the results of a survey conducted among fishermen,... |

| The scope of this paper is to quantify, for a wide selection of European fisheries, fishing tactics and strategies and to evaluate the benefits of adjusting the definition of. fishing effort using these elements. Fishing tactics and strategies were identified by metiers choices and a series of indices. These indices have been derived to reflect shifts in tactics (within a fishing trip) and in strategies (within a year). The Shannon-Wiener spatial diversity indices of fishing tactics (FT_SW) and strategies (YE_SW) had the greatest impact on catch rates. In particular, FT_SW was always negatively correlated to catch rates. One may anticipate that during a fishing trip, vessels with high FT_SW have been searching fish aggregations for a long time, while... |
