Evaluating Seafood Distribution Channels In The Atlantic Sea Scallop And Northeast Multispecies Groundfish Fisheries, Amanda Fall
Evaluating Seafood Distribution Channels In The Atlantic Sea Scallop And Northeast Multispecies Groundfish Fisheries, Amanda Fall
Electronic Theses and Dissertations
Federal fisheries policy in the United States aims to balance resource conservation with maximum sustainable use. Catch shares are a quota-based management tool that are being increasingly deployed to achieve this ambitious goal. One perceived benefit of catch shares is that they give fishermen control of their catch so they will have the latitude to pursue the most profitable marketing arrangements. Using a mixed-methods approach, this research seeks to (1) describe and document the different marketing strategies that commercial fishermen in the Northeast Multispecies Groundfish and Atlantic Sea Scallop fisheries are using to sell their catch; and (2) estimate the …
Developing A Collaborative Research Program To Evaluate Fine-Scale Groundfish Dynamics In Eastern Maine, Mattie Rodrigue
Developing A Collaborative Research Program To Evaluate Fine-Scale Groundfish Dynamics In Eastern Maine, Mattie Rodrigue
Electronic Theses and Dissertations
Fisheries science conducted and used for management strategies in the Gulf of Maine (GOM) is conducted at broad spatial and temporal scales. There is a tendency for fisheries-independent monitoring programs, which play a critical role in fisheries assessment and management, to miss fine-scale dynamics, especially given the complex hydrographic structures characterizing the GOM. In New England, fishermen participating in a heterogeneous groundfish fishery within the GOM may have varied perceptions of fish abundance or distribution depending on the scale at which they participate in the fishery. Overlooking fine-scale life-history dynamics coupled with scale-mismatch in science and management may perpetuate a …
An Analysis Of Gulf Of Maine Cod Metapopulation Structure And Localized Stability, With Application To Area-Based Fisheries Management, Derek Olson
Electronic Theses and Dissertations
The complex metapopulation structure of groundfish stocks in the Gulf of Maine, particularly Atlantic cod (Gadus morhua), is largely ignored under the current system of broad-scale stock assessment and management. This mismatch of biological and administrative scales has contributed to severe overall stock decline and localized serial depletion of Gulf of Maine cod. Such chronic management failure has led to growing calls for a more area-based, finer-scale approach to managing groundfish in the Gulf of Maine. A primary difficulty hindering the development of finer-scale groundfish management has been the challenge of estimating fishing mortality upon local stock components. …
Connecting Rivers For Healthy Ocean Fisheries, Catherine Schmitt
Connecting Rivers For Healthy Ocean Fisheries, Catherine Schmitt
Maine Sea Grant Publications
Across Maine, communities and land owners are reconnecting rivers and streams by improving road crossings, fixing broken culverts, and removing dams and other barriers. There are many reasons for doing this work, including preventing costly repairs associated with flooding and washouts, enhancing water quality, increasing wildlife habitat, and restoring fish populations. Connecting Rivers explores some of the ways that streams connect inland lakes and forests and the sea. This first fact sheet in the series focuses on connections between populations of migratory river fish (alewives and blueback herring) and groundfish (e.g., cod).
The Cost Of Useful Knowledge And Collective Action In Three Fisheries, James A. Wilson, James M. Acheson, Teresa Johnson
The Cost Of Useful Knowledge And Collective Action In Three Fisheries, James A. Wilson, James M. Acheson, Teresa Johnson
James Wilson
In a complex environment knowledge is valuable and its acquisition is costly; as a result people are careful about what to learn and how to learn it. We suggest that the dynamics of the “local” environment strongly influences the method that individuals choose to acquire useful knowledge and is one of the principal determinants of the way they compete and cooperate. We focus on theway different environments lead to different costs, especially the relative opportunity costs of search and communication and, consequently, to the emergence of different patterns of persistent cooperation and competition. In predictably regular and in predictably random …
