Species and habitats - Mullus surmuletus - All ages - IBTS Multi-annual abundance in summer (1991-2000, 2001-2010)
Due to data paucity, the interpolated maps were computed using all the data available over two periods : 1991-2000 and 2001-2010. Biologic data have been expressed in abundance (numbers or density values (nbr/km²)) and always required to be log-transformed using a log10(x+1) transformation.
