The Need for Fisheries Reform
![Page 3: DAP Fisheries Reform](https://reader034.fdocuments.net/reader034/viewer/2022051112/55a270ac1a28ab4a278b4719/html5/thumbnails/3.jpg)
Catch Shares
Catch shares allocate the privilege to harvest a percentage share of the total catch to individual fishermen, communities, or associations

Recommendation: Scenario 2
Positives
High gains from trade Increase in stewardship
Biomass Compliance
Increases long term sustainability and short term profits in both industries
Generates Essential Fishery Information (EFI)
![Page 20: DAP Fisheries Reform](https://reader034.fdocuments.net/reader034/viewer/2022051112/55a270ac1a28ab4a278b4719/html5/thumbnails/20.jpg)
Scenario 2: A Closer Look
Challenges
Potential size high-grading and discards
Setting accurate recreational and commercial harvest limits for species and species complexes
Increased complexity of regulation

The Wider Scope
A fishery management system that integrates commercial and recreational sectors can result in greater benefits than a system that manages sectors separately.

Sensitivity Analysis
Economic model was most sensitive to: Commercial Costs Angler Age
Economic Model was run using a high and low estimate to maximize and minimize the effects on distribution and gains from trade
Results then run through the Environmental and Social and then Political Model
Scenario 2 was still the favored scenario
