The
main purpose of these data layers is to help inform the National Marine
Fisheries Service Biological Opinion on Continuing Operation of the
Pacific Coast Groundfish Fishery (NMFS 2012). In 2011, new regulations
governing the limited entry bottom trawl and midwater trawl fisheries
led to the induction of individual fishing quotas (IFQs). Primary goals
of IFQ management included decreased bycatch and increased catch
accountability, profitability, and efficiency. In the shoreside bottom
trawl fishery, permit holders with IFQ and a trawl endorsement can use
multiple gear types (although not within the same trip), including
bottom trawl, midwater trawl, hook-and-line gear, and pot gear. These
management changes could impact fishing effort in trawl sectors, as well
as alter fixed gear fishing effort by providing a new opportunity for
fixed gear fishing activity and potential competition between IFQ and
other fixed gear sectors. These data layers display fishing effort to
assess these potential changes.
