We evaluate whether changes in geographic distribution of landings coincided with implementation of individual transferable quotas (ITQs) in the limited-entry groundfish trawl fishery on the U.S. Pacific coast. We use a spatial Theil index, kernel density functions of port revenue share, and Shorrocks index of intradistributional mobility to measure changes in spatial distribution. We find evidence of increased spatial concentration; however, this appears consistent with preexisting trends and not related to ITQs. Further, we find a high degree of intradistributional mobility in the revenue share of ports that coincided with ITQ implementation.
