Increase in Purse Seine Vessels Overall, but Fewer Large Scale Purse Seine Vessels Fishing for Tropical Tuna Species Globally

The International Seafood Sustainability Foundation (ISSF) has updated its report Large-Scale Tuna Purse Seine Fishing Fleets as of July 2021. The total number of purse seine vessels, calculated based on data from the five tuna Regional Fisheries Management Organizations (RFMOs), has increased from 1,721 in 2020 to 1,855 today. The report also shows approximately 678 vessels (down 2.6 percent from last year) defined as large-scale purse seine (LSPS) vessels targeting tropical tuna species (skipjack, yellowfin, and bigeye), with a combined fishing capacity of over 865,000 m3 (cubic meters). 

Having an accurate estimate of active vessels is critical for managing tuna fishing capacity regionally as well as globally. Although purse seine vessels account for approximately 69 percent of the 5.0 million-tonne global tuna catch, multiple databases must be searched to compile a count of all authorized purse seine vessels. To provide an annual best estimate — and to track capacity changes from year to year — ISSF analyzes and aggregates information from the five tuna RFMOs and other sources.

Helping Fisheries Managers Better Monitor and Enforce Requirements for Member States

What good are regulations if they’re not followed? Why adopt policies without a strong plan to monitor adherence to them?  

In an era of greater expectations regarding transparency and accountability, these are the questions stakeholders are increasingly asking of RFMOs. And for tuna fisheries, a vital, global food source and economic engine, those expectations are especially heightened. Now, a group of policy experts is stepping in to help tuna RFMOs continue strengthening their compliance processes.
