Resumo: The sea related activities always had great importance in Portugal, especially the fishing activity and the processing industry of marine products. However, in the last decades, the decrease of both activities has occurred, with a significant reduction in the number of fishermen and fishing fleet and a major reduction on the number of canning factories in activity, mainly due to the Common Fisheries Politics of EU. In this work, an analysis of the species which make up the food product that retains the case of Auxis spp. (Judeu) and Euthynnus alletteratus (Merma), captured on the Algarve coast and recovered through the process of appertised canning, in nearby Andaluzia, with the designation of "Melva de Andalucía". A sample of 128 individuals was analyzed, in terms of morphometric composition and feeding behavior. The analysis of capture volumes and selling prices variation, in harbor, from 1996 to 2010 was also performed. The assiduous presence of this species was verified, mainly in the summer months, mostly between July and September, when the surface water temperature is higher, although statistically it was not proven, showing similar population composition and feeding and reproductive behavior, in agreement with other authors Works, for the Mediterranean. A sensory evaluation to “Melva de Andalucía” with two other samples of appertised canned products commercialized in Portugal, of similar market segment was performed. The obtained results showed positive answer to the product acceptance by the tasters.
