GMIS - Favourable feeding habitat of skipjack tuna (SKJT) Monthly 1998-2017 (frequency of occurence, %)

Collection: GMIS : Global Marine Information System 

Description

The favourable feeding habitat of skipjack tuna is daily identified linking their ecological traits with environmental variables from satellite remote sensing and physical ocean models. The feeding habitat is mostly related to the occurrence of productive oceanic features (such as eddies) that are detected by satellite sensors of ocean colour (chlorophyll-a fronts). The physical variables used are sea surface temperature, sea surface salinity, sea surface current, sea surface dissolved oxygen, mixed layer depth and sea surface height anomaly.

Lineage information

General information: Model performance is assessed against the distance of presence data to closest habitat. For skipjack tuna, 75% of observations related to free-swimming schools are closer than 38.5 km of favourable feeding habitat (n = 7110, less than 90 km in the Atlantic [n = 2806] and less than 5 km in the Indian Ocean [n = 4304]). For skipjack tuna, 75% of observations related to fishing aggregating devices are closer than 42.2 km of favourable feeding habitat (n = 30413, less than 200 km in the Atlantic [n = 3455] and less than 22 km in the Indian Ocean [n = 26958]).
