  Citation × Citation Citation Abstract Copy Title: Evolving Bycatch Risk in the Pacific Groundfish Trawl IFQ Author: Holland, Dan Catches of several potential choke species in the Pacific groundfish IFQ are highly uncertain and tend to be concentrated while quota is broadly distributed. An analysis prior to implementation of the IFQ suggested substantial risk of individual vessels accidentally exceeding quota allocations for several rockfish species and Pacific halibut. Many fishermen lacked confidence that they would be able to acquire quota on the market to cover incidental catch and consequently joined risk pools to mitigate this risk. I update the analysis of bycatch risk using tow level catch data since implementation of the IFQ. The analysis indicates that expected catch rates of most choke species have declined suggesting more effective bycatch avoidance behavior. However, there remains a significant risk that vessels’ catch of some choke species can be several times median quota allocations, in part because many vessels have increased catch and effort by leasing quota pounds, but quota share ownership has remained distributed. The results underscore the importance of an efficient quota market to redistribute quota to match realized catches, but a recent analysis suggests that the quota market is not distributing quota effectively and is subject to high transactions costs.  This provides and explanation for the persistence of risk pools despite the fact that aggregate catches of overfished rockfish species and Pacific halibut have remained well below total quotas.   Title: Evolving Bycatch Risk in the Pacific Groundfish Trawl IFQ Author: Holland, Dan Catches of several potential choke species in the Pacific groundfish IFQ are highly uncertain and tend to be concentrated while quota is broadly distributed.

  Citation × Citation Citation Abstract Copy Title: Measuring the Value of Forage Fish to Recreational Fishermen Author: Lipton, Doug, Hutniczak, Barbara, Townsend, Howard Fisheries management has been traditionally single-species oriented. Only recently more pressure has been put on developing a holistic, science-based approach that considers the ecosystem as a whole. This approach is widely known as ecosystem-based fisheries management (EBFM). One of the most often highlighted aspects of EBFM is the relevance of predator-prey interactions in the aquatic ecosystems. The motivation is that there are considerable trade-offs between the supporting role of forage species as energy conveyors in food webs and provisioning service as target species to fisheries. We study this aspect by looking at the Chesapeake Bay. The motivation is a recent debate on the potential impact of excessive forage base fishing. In particular, we are interested in the propagation of forage overfishing through the food web and its influence on more valuable, higher trophic species fisheries. We develop a Bayesian model of recreational harvest of striped bass where benefits are derived from stock size as well as age structure. The age structure drives the probability of catching a fish of a particular size what is of considerable importance to the fishery highly constrained by minimum catch size regulations. Then, using a dynamic multispecies framework (Ecosim) and modified random utility model, we analyze multiple scenarios varying by menhaden regulations and derive benefits changes imposed on the striped bass recreational fishery. We focus on the recreational sector as recent research indicates that the recreational fishing is becoming increasingly important and new management strategies may be necessary to address this shifting trend.
