The medieval fisheries of Galicia (Northwestern Iberia): A preliminary archaeozoological overview

The origin and development of the Iberian Medieval fisheries is a poorly documented phenomenon both from the standpoint of historical (documentary) and material (archaeological) evidence. Such dearth of knowledge can be explained in terms of proximal (i.e., a deficient retrieval of fish remains) and ultimate causes. Among the latter, the Muslim invasion, that lasted ca. 800 years of the "medieval millennium" in the Iberian Peninsula, needs to be taken into account as it probably delayed the development of fishing fleets within the Christian kingdoms for a substantial period of time. Be it as it may, the lack of knowledge does not allow one to explore a range of critical issues of Spanish and Portuguese history, such as the role played by the ever-expanding fishing fleets of Portugal and Castilla in the process of maritime discovery and colonization that these two kingdoms fostered by the end of the Middle Ages. In this paper, the results from a comparative analysis of selected fish assemblages from primary (i.e. coastal) deposits of the northern Iberian shores are presented. The aim is to check whether changes can be documented both at the level of (1) the range of species occurring in sites from the late Iron Age (Castrena culture, IV-I BC) to the Late Middle Ages (XV AD), and (2) the skeletal spectra of certain species that could reveal a differential processing of taxa meant for local consumption and those that appear in inland sites.
