Applying Benefit Transfer to Improve the Transfer of Ecological Estimates in Ecosystem Services Research and Policy

Creator:: Errend, Melissa, DeWitt, Ted, and Moon, J. B.
Abstract:: Ecosystem services (ES) represent a way to represent and quantify multiple uses, values as well as connectivity between ecosystem processes and human well-being. Ecosystem-based fisheries management approaches may seek to quantify expected trade-offs in ecosystem services due to actions such as restoration and gear restrictions, or due to changes such...

How Biological Data Has Contributed to Management Plans in the Bay of La Paz: Los Islotes Sea Lion Rookery as Case of Study

Creator:: Labrada Martagón, Vanessa
Abstract:: Los Islotes is the southernmost breeding site of the California sea lion (Zalophus californianus) in Northern Hemisphere and represents one of the most important economic activities for the city of La Paz, Mexico. The increasing tourism activity grew without any control until researchers and organizations started to be concerned about...

Collective Rights in Artisanal Fisheries and the Trade-Offs in Fisheries Policies: An Analysis of Distributive Policies

Creator:: Jara-Iturra, Miguel, Dresdner-Cid, Jorge, and Gomez, Walter
Abstract:: This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...

Reference Points for Vulnerable Fish Species Based on Bioeconomic Age-Structured Models: An Approach for Totoaba macdonaldi

Creator:: Rodríguez-García, Oswaldo Uriel, De Anda-Montañez, Juan Antonio, Valenzuela-Quiñonez, Fausto, Hernández-Flores, Alvaro, Salas-Márquez, Silvia, and María Da-Rocha, José
Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

The Price of Lobster, Forecasts and Simulation in a ARDL- Bounds Testing Framework

Creator:: Gordon, Daniel
Abstract:: Economists have long been interested in empirically modelling/forecasting the price of staple commodities using both structural and reduced form models. The purpose of this paper is to apply Pesaran’s Autoregressive Distributed Lag/ Error-Correction Bounds model for forecasting the ex-vessel price of lobster on the east coast of Canada using monthly...

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...

Biosecurity vs. Profits: A Multi-Objective Model for the Aquaculture Industry

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...

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...

A Small Parasite Making Big Waves: Industry Consolidation and Collaboration under Spatial-Dynamic Externalities

Creator:: Morency-Lavoie, Félix, Nøstbakken, Linda, and Abbott, Joshua
Abstract:: Parasites and diseases represent major challenges in aquaculture. In the Norwegian salmon farming industry, costs associated with treatment of sea lice are surging and reached 5bn NOK or 10% of the industry’s total export value in 2015. In addition to the direct impact on production, sea lice affect the industry...

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...
