It is timely to hold an international symposium on data-limited and data-poor fish populations that are harvested commercially or recreationally. The Lowell Wakefield Symposium on "Fisheries Assessment and Management in Data-Limited Situations” was held in 2003. Since then, fisheries management around the world has expanded to consider more species and fisheries and to impose more precautionary regulations, such as catch limits. In Alaska data limitations affect management of commercial fisheries, including sharks, rays, octopus, scallops, some crabs and rockfish, and others. Data limitations are pervasive in most other fisheries jurisdictions around the world. Most recreational fisheries are also data-poor.
There is a need for new tools and strategies for setting appropriate catch limits and other regulations for fisheries under data-limited situations. In the United States, much of this has been driven by the requirement to set catch limits for all marine fisheries managed by the federal government. Fisheries assessment and management worldwide are especially difficult when only commercial catch data are available. Catch data may be highly uncertain due to inadequate or incomplete sampling, unreliable estimates of discards, and lack of knowledge about recreational harvests. High levels of uncertainty about stock status and optimum yield associated with inadequate data and science can lead to either overharvest or forgone yield, both of which have negative socioeconomic impacts. Problems are magnified for stocks that are assessed infrequently.
Recreational fisheries are fundamentally different from commercial fisheries in goals (maximize fishing opportunities) and management tools (e.g., bag and size limits). Given the diversity of recreational fisheries and fishermen, it is difficult to collect sufficient data. Management is especially difficult in fisheries with large commercial and recreational sectors, with even greater problems in data limitations.
Goal of the Symposium
The goal of the international symposium is to encourage development of new tools and strategies for assessment and management of data-limited commercial and recreational fisheries in marine and freshwater areas. Presentations are sought on new quantitative stock assessment tools under data limitations, methods to incorporate uncertainty in assessment and management, improved approaches for inclusion of social and economic considerations into management, and strategies for the management of mixed commercial and recreational fisheries. Presentations about new assessment approaches for stocks without routine surveys or indices of abundance are especially welcome. Methods for determining catch limits and alternative management measures to catch limits in data-poor situations are also of great interest.
The registration fee for the symposium is $275 US ($225 student) if paid on or before April 13, 2015. The late registration fee will be $325 ($275 student) after April 13. If your abstract is accepted for presentation, you must register and pay the symposium fee by April 13 to secure a place on the program. The fee covers continental breakfast and break refreshments daily, a catered reception, symposium materials, and published proceedings. Please register and pay your fees in advance so that adequate materials are available. Payment can be made with credit card or check.
Registration fee refunds: 75% refund for cancellations up to one week prior to symposium; no refund after May 5.
