Creator:: Hariharan, Aneesh, Gallucci, Vincent, Anderson, Chris, McFarlane, Sandy, and Fluharty, David
Abstract:: The Pacific sardine fishery is shared but independently managed by three nations: Canada, USA and Mexico. As a result, potential conflict scenarios may arise. A stochastic optimal control methodology is presented to analyze potential conflict scenarios by first considering a deterministic logistic stock growth function and adding a stochastic term,...

Creator:: Ropicki, Andrew and Larkin, Sherry
Abstract:: During the first three years (2007-2009) of the Gulf of Mexico red snapper IFQ program most quota lease trades were local, involving fishers that lived in the same communities. In 2010, the red snapper quota lease market changed as more IFQ participants began trading quota with fishers from different regions...

Creator:: Ravn-Jonsen, Lars, Andersen, Ken H., and Vestergaard, Niels
Abstract:: Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...

Creator:: Abbott, Joshua K. and Willard, Daniel
Abstract:: Recreational fishing for popular species like red snapper and grouper in the Gulf of Mexico has followed a familiar pattern to that observed in many commercial fisheries: fishing under regulated open access has promoted a “race to the fish” with cascades of shorter seasons, shrinking bag limits, and significant fishery...

Creator:: Dresdner-Cid, Jorge and Estay-Montecinos, Manuel
Abstract:: In this paper we measure the value of sanitary restrictions in terms of forgone profits. For this we model the trade-off between biosecurity and profits in the salmon aquaculture industry. We introduce the concept of “sanitary desirable volume” of the salmon industry, as a goal in a bi-objective model. We...

Creator:: Kasperski, Stephen and Hsueh, Lily
Abstract:: "Rationalization” or the change to catch share management in fisheries has been shown to lead to the slowing of fishing activity, input and effort consolidation, cost savings, as well as new market and product development. The effects of rationalization on fishermen’s behavior become more complex when one accounts for the...

Creator:: Joyce, Jessica and Barney, Amanda
Abstract:: Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...

Creator:: Abbott, Joshua K. and Fenichel, Eli P.
Abstract:: Fisheries sustainability is a much sought-after goal. Yet, “sustainability” is often too ambiguously defined to be of much practical guidance to policymakers. Furthermore, fisheries managers are increasingly expected to assess and manage fisheries in an “ecosystem-based” manner – accounting for the ecological interdependencies of species and their coupling with the...

Creator:: Holland, Daniel S.
Abstract:: In 2011 an individual fishing quota (IFQ) system was implemented for the limited entry trawl component of the Pacific groundfish fishery in the US. The IFQ system allocates quota shares (QS) for 29 IFQ stocks and individual bycatch quota (IBQ) shares for Pacific halibut. Each year quota shareholders are issued...

Creator:: Hutniczak, Barbara and Vestergaard, Niels
Abstract:: The paper analyzes a situation in which the fishing fleet is subject to restrictive regulation regarding the harvest of its primal target species due to biological overfishing that in turn reveals a high level of overcapacity. The goal is to model fishermen’s expectations and likely responses to the government initiated...
