Modeled demersal and pelagic high bycatch fishing pressure.
How Was It Measured?
This Pressure represents fish caught using high bycatch gear, which includes demersal destructive (e.g. trawl), demersal non-destructive (e.g. pots, traps) and pelagic (e.g. long-lines) 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).
