Économie de pêche au Mésolithique et diversité piscicole à l'Holocène ancien dans le bassin hydrographique du Doubs

Abstract : This dissertation focuses on understanding fishing practices and their role in human subsistence economies during the Late-Glacial/Earl Holocene transition, through the ichtyo-archaeological study of over 11,000 fish bone remains. The remains original from four archaeological sites of the Doubs hydrographical basin (Jura, France), namely the Cabônes rock-shelter in Ranchot ( 1 very large assemblage dating from the Boreal period),Rochedane in Villars-sous-Dampjoux (5 assemblages spanning the Epipaleolithic to the Mesolithic), Gigot in Bretonvillers (2 mesolithic assemblages) and Roche-aux-Pêcheurs in Villers-le-Lac (2 mesolithic assemblages). After an initial reassessment of the most common analytical tools used in ichtyo-archaeology, we developed a thorough protocol allowing bath the characterisation of our assemblages (origin of deposit, taxonomical identification, quantification, body-size and weight estimates and the economic analysis of fishing as a subsistence activity. Fishing appears to have been practiced year-round, with an increase in catch at the beginning of the warm season. The activity stayed very local, and targeted ail of the available species. Fishermen seem to have favoured intermediate river environments, such as shallow banks o side channels, most suitable for setting fish-traps. The prey was then consumed directly on site, apparently without any prior preparation, and the refuse was discarded in the immediate vicinity, often around healths. Late-Glacial and Early Holocene societies of France demonstrate an excellent command of the exploitation of fluvial resources, and fishing appears to have been optimized to maximise yield-to-effort ratios.
