Data-Limited Fisheries 101

We know very little about the sustainable limits of most fisheries in the world, with an estimated 80% of global catch comprised of fish species that have not been assessed for population status and whether current catch levels are sustainable.

Dozens of Peer-Reviewed & Published Data-Limited Methods

Including both output controls (e.g., total allowable catch) and input controls (e.g., spatial, effort, size)

Rapid Execution

Pre-tested code and parallel computing for speed and efficiency

Improves Data Collection

Prioritizes data collection priorities to ensure the biggest bang for the buck

Open Access

Free R software package enables users to share code for easy collaboration

Customizable

Quickly add new management procedures, performance metrics, and fishery types to accommodate an ever-expanding universe of fishery management problems

Flexible MSE Model

Saves time developing new MSE frameworks

Clarity & Transparency

Provides clarity in decision-making and promote transparency, credibility, and increased buy-in from stakeholders
