| The growth study of s tripped Mullet, from the Bay of Biscaye, from April to June is managed by scale reading. Sorne difficulties appear with the interpretation female scales. The Analysis of ovaries confirms that spring is the period of reproduction, and shows that the age of first reproduction is two year (65 %) or one year old (35 %). Secondly, the exploitation of various statistic data shows the evolution of landings of Stripped Mullet in several harbours, and especially in les Sables d'Olonne, since 1962. The reconstitution of the artisan trowlers effort in this harbour confirms the long decline of c.p.u.e . for Mullus surmuletus, and a rapid increase since 1981.

| This document presents a comparative assessment of four triannual analyses carried out between 1986 and 1995, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gear used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels Over the period, an average of 11 components have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics (gears,... |
