Accompagnement vers l'éco-certification de la pêcherie artisanale méditerranéenne de Thon Rouge de ligne : amélioration du suivi des captures accessoires et acceptation du projet par les professionnels

Abstract : Bluefin Tuna (Thunnus thynnus) is an emblematic species which, weakened by intensive fishing in the 1990's, is under strict control measures to ensure sustainable fishing. Despite the now positive scientific evaluations, public opinion still considers this species as threatened. So, the French Producers Organisation SATHOAN wishes to continue valorisation actions for the species, being involved in an eco-certification process for its Mediterranean Bluefin tuna artisanal longline and handline fishery. In this framework, an improvement of the by-catch monitoring system is needed. Indeed, two tools to collect information on the caught species are developed and introduced into fishing practices (mobile app, paper book), and three solutions for geo-location of these catches are proposed. Primaries statistical and cartographic analyzes of these collected data enable to describe these catches (share of species in total catches, seasonality, spatial associations...). Furthermore, to ensure the new tools durability, driving and hindering factors for eco-certification acceptance by fishermen are evaluated thanks to semi-directives interviews. Apart from the detail of the driving and hindering factors, this allows to identify a priori evaluation factors of fisherman's ability to accept new tools (three standards came out : relations with the downstream die, capacity of talking, perception of the environment). Measures to improve adherence of fishermen to eco-certification approach are proposed and can be mobilized by the PO.
