The favourable spawning habitat of the Atlantic bluefin tuna is daily identified linking their ecological traits with environmental variables from satellite remote sensing and physical ocean models. The spawning habitat (Atlantic bluefin tuna only) is essentially detected through the seasonal heating of surface waters. Adult bluefin tunas migrate thousands of kilometres to spawn in warmer and less productive waters (Mediterranean Sea and Gulf of Mexico) compared to their main feeding ground (North Atlantic Ocean). The physical variables used are sea surface temperature, monthly increase of sea surface temperature, sea surface current and sea surface height anomaly.

General information: Model performance is assessed against the distance of presence data to closest habitat. For bluefin tuna, 75% of observations are closer than 13.9 km of favourable spawning habitat (n = 582).
