Fishermen, Markets, and Population Diversity

Creator:

Jardine, Sunny and Sanchirico, James N.

Abstract:

Fishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity, targeting populations within a species can impact population diversity, and targeting valuable species can impact biodiversity at the ecosystem...

Assessing the Value and Role of Seafood Traceability from an Entire Value-Chain Perspective

Creator:

Sylvia, Gil, Sterling, Brian, Gooch, Martin, Dent, Benjamin, Marenick, Nicole, and Miller, Alex

Abstract:

The traceability practices of 48 seafood businesses were assessed as part of an evaluation of nine global seafood value chains (from harvest to retail). The research was conducted through direct interviews and written surveys in order to assess the reasons why traceability systems were used to strengthen business performance. The...

Indicators for Ecosystem Externalities in Fishing

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...

An Iterated Multiyear Simulation Model to Assess Impacts of Halibut Bycatch Limits

Creator:

Hartley, Marcus

Abstract:

Bering Sea/Aleutian Islands (BSAI) groundfish fisheries are hugely productive with 2008 – 2014 harvests averaging 1.6 million tons and generating $1.95 billion annually. The BSAI also hosts a commercial halibut fishery with 2013 landings of 3,500 tons and revenues of $41.5 million. Downward trends in halibut biomass combined with continued...

The Cost of Avoiding Sea Cucumber Stock Depletion

Creator:

Hernández-Flores, Alvaro, Cuevas-Jiménez, Alfonso, and Aranda-Nah, Javier

Abstract:

In 2013 a stock of sea cucumber (Isostichopus badionotus) was discovered in northern shelf of Yucatan. A survey calculated a biomass of 17,600 tons. The species has an attractive price for local fishers, therefore, in order to avoid the “race for sea cucumbers” and the collapse of the stock, authorities...

Competitive Markets in Stochastic Environments: Will Climate Change Drive Industry Consolidation of Global Fisheries?

Creator:

Scheld, Andrew M.

Abstract:

Climate change and continued fishing pressure threaten to increase recruitment variability for many stocks globally. Shifts in the inter-annual stability of an exploitable renewable resource may have dramatic consequences for the industries and communities which depend upon them. In this talk, the link between resource volatility and industry structure is...

Data Collection and Measurement in the Northeast US

Creator:

Rountree, Barbara

Abstract:

The Resource Evaluation and Assessment Division’s Social Sciences Branch (SSB) in the NOAA Northeast region is preparing for an external review in 2017 to evaluate its programs alignment between the strategic objectives of SSB, NEFSC, NMFS, and NOAA. In previous SSB and NEFSC wide reviews, much attention has been drawn...

Recent Adjustments in Northeast US Fresh Groundfish and Scallop Processing and Marketing

Creator:

Georgianna, Daniel and Lee, Min-Yang

Abstract:

The North Atlantic U.S. groundfish and scallop processing industries are a tale of two fisheries. The groundfish processing industry has suffered a steep, almost continual decline in landings starting in 1984 that resulted in 2014 landings that were only 16% of 1983 landings. US scallop landings increased from 5 million...

Least-Cost Bycatch Reduction Through the Biodiversity Mitigation Hierarchy

Creator:

Squires, Dale and Garcia, Serge

Abstract:

The Biodiversity Impact Mitigation (BIM) hierarchy provides an overarching conservation framework for bycatch reduction, and more broadly for biodiversity conservation. This framework includes four steps, which are implemented sequentially to: (i) avoid and (ii) minimize impacts; (iii) rehabilitate/restore impacted biodiversity; and (iv), compensate such impacts, usually elsewhere. The first three steps...

Data Management and Analysis Challenges in Describing Social and Economic Aspects of a Small-Scale Commercial Marine Fishery

Creator:

Galligan, Monica, Pomeroy, Caroline, Reilly, Paul, Culver, Carolynn, and Cannon, S.

Abstract:

As part of an effort to describe the recent history and socioeconomics of a small commercial fishery, we were provided access to a large, multi-faceted data set. In using those data, we faced a number of challenges related to data management, data protection and confidentiality, and needed to develop effective...
