Commercial Fishing: Low Bycatch

Modeled demersal and pelagic low bycatch fishing pressure.

This Pressure represents fish caught using low bycatch gear, which includes demersal non-destructive (e.g. hook and line) and pelagic (e.g. purse seines) gear. The species-gear associations are from Watson et al. Catch data are from 2006 and were spatialized by the Sea Around Us Project into ½ degree cell resolution. These values were then summed into EEZ reporting units; when cells spanned EEZ borders, catch was divided proportionally based upon amount of area in each EEZ. Full details for this data layer are provided in Halpern et al. (2008).
