Abstract
  • Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas.  They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries these changes may be hard to predict since the value of quota and the amount and distribution of catch of primary target species may be dependent on prices, abundance, distribution, and quota availability of other jointly caught species.   We analyze how the implementation of IFQs in the Pacific groundfish fishery has, and may in future, shift the distribution of catches, effort and revenue in the fishery. We focus on the most valuable component of the groundfish fishery that targets sablefish, either independently using fixed gear, or jointly with dover sole and thornyhead rockfish using trawl gear. We simulate the effects of changes in prices of sablefish, dover sole and fuel on trip level profitability.  Our analysis suggests significant differences in the value of sablefish quota by gear and some regional differences that could lead to shifts in where and how sablefish quota is used. These shifts can have important ecological as well as distributional consequences. Our analysis also shows that relative profitability is quite sensitive to changes in fish and fuel prices with the range of changes seen in recent years. Thus movement of sablefish spatially and between gears is likely to be dynamic going forward.
