Figure Overview of the different surveys used for the specific ICES Sub-divisions The table shows the Survey name, the International Council for the Exploration of the Sea (ICES) sub-division in which the survey is undertaken, the gear used in the survey, the initial start date of the survey and the quarter used for the assessments.
Figure Temporal development of the ratio of the number of Lusitanian species to the number of Boreal species The maps show the temporal development of the ratio between the number of warm-favouring (Lusitanian) fish species and the number of cool-favouring (Boreal) fish species by The International Council for the Exploration of the Sea (ICES) statistical area in 8-year intervals from 1982 to 2022.
Figure Temporal development of the number of species of each biogeographical affinity group (top) and of the ratio between Lusitanian and Boreal species with sea surface temperature (bottom) by marine region The charts show: Top figures: the temporal development in the number of species of each biogeographical affinity group (Atlantic, Boreal, Lusitania and Unknown) by marine region (Greater North Sea, Baltic Sea, Celtic Seas and Bay of Biscay and the Iberian Coast). Bottom figures: the temporal development of the ratio between Lusitanian and Boreal species and sea surface temperature by marine region to investigate correlations.
