Small-scale fisheries in Canary Islands is made by small boats with passive fishing gears performing polyvalenceand with multiple aim species, with local landing and selling of the catches, with great socio-economic and cultura limportance at the local scale and with a fishers behavior highly influenced by the search of the economic viability of their multiple aim species exploitation. TROPICALIZATION OF COASTAL ICHTHYOFAUNA: 1. Natural expansion of distribution range (1980-2010). 2. In addition, Introduction of tropical species (2010-TODAY) 3. Population decrease of temperate/cold species. MERIDIONALIZATION: Population increase of NATIVE thermophilic species, some towards the colder Eastern islands. Here we present some preliminary results of the tropicalization of landings performed by commercial fisheries, based on the official sale notes information.
