Crustacean output rose (up 64.1% in volume and 6.2% in value) mainly because of an increase in prawn harvests. In the latter, the overall decline was due mainly to a decrease in catches of the regions’ more important species, notably tuna in the Azores and black swordfish in Madeira. At the national level, annual average prices at auctions were also found to be slightly higher in 2009 than in the previous year (up 2.7%).
