Status of the World Fisheries for Tuna

The Status of the World Fisheries for Tuna provides information on the status of stocks, bycatch and mitigation issues and a review of programs that regional fisheries management organizations (RFMOs) have undertaken to manage tunas and related species, and to examine how effective these programs are in conserving the stocks of target and non-target species.

The Report
ISSF tracks the health of the four main species of tunas – yellowfin (YFT), bigeye (BET), skipjack (SKJ), and albacore (ALB) – in each of the ocean areas covered by an RFMO responsible for the conservation and management of these species.

This status report differs from the previous editions prepared by ISSF with the incorporation of a new rating factor related the environmental impact, in terms of bycatch, of the principal gear(s) used to fish each stock. The ratings are thus prepared for three factors: Abundance, Fishing Mortality and Environment (bycatch).
