Slick is a decision analysis tool that presents the outcomes of candidate harvest strategies across various states of nature, accounting for uncertainty. Slick is interactive and allows users to filter results live in order to explore robustness and performance.
While Slick can be applied to any decision analysis context it was specifically designed to investigate the performance of harvest strategies tested by management strategy evaluation (MSE). Slick can be used for any MSE process, but the current version includes a demonstration example, as well as preliminary results from the MSEs for Western Atlantic skipjack tuna and North Atlantic swordfish.

The GFCM has adopted 2025’s first international #harveststrategy, choosing a precautionary, science-based rule for blackspot seabream in the Alboran Sea. With the stock at only ~5% of unfished levels, this is a key step toward recovery and sustainability:
Upcoming trilateral (EU-NO-UK) talks are crucial for North Sea herring. Managers can adopt a new #MSE-tested long-term management strategy that considers herring’s ecosystem role and supports stable, sustainable catches for 2026 and beyond. Read more:
Experts across RFMOs met at the Global Blue Shark MSE Workshop to advance sustainable management of this highly valuable species. Read more on key discussions, shared challenges, and progress toward robust, MSE-tested management procedures for blue sharks:
