This tuna tends to travel in single species schools, without the level of mixing seen in other species. Association with floating objects is not common.

Albacore accounted for about 4% of the 4.9-million-tonne global tuna catch in 2020.

Albacore Tuna Stock Status

Our Status of the Stocks report summarizes the status of albacore tuna worldwide according to the most recent scientific assessments. The report includes:

  • Catch data
  • Graphics and charts
  • Ratings on stock abundance, fishing mortality, and fishing’s environmental or bycatch impact

It also reviews the management measures for albacore that Regional Fisheries Management Organizations (RFMOs) have adopted.
