Regulators changing fishing rules to protect endangered tuna

January 4, 2017 — PORTLAND, Maine — The federal government is changing some of the rules about how fishermen harvest tuna in an attempt to protect one of the species of the fish.

The National Marine Fisheries Service says the rule change is designed to steer fishermen who catch yellowfin tuna and swordfish via longline away from bluefin tuna.

Atlantic bluefin tuna are listed as endangered by the International Union for Conservation of Nature. Fishing boats sometimes catch them incidentally while targeting other species.

The fisheries service says the rule change will modify the way it handles distribution of quota transfers in the longline tuna fishery. The service says that flexibility will improve fishing opportunities while limiting the number of bluefin tuna that are incidentally caught.

Australia rejects yellowfin tuna TAC increase

November 16, 2016 — The Australian Fisheries Management Authority (AFMA) Commission said it did not support an increase in the total allowable catch (TAC) increase of yellowfin tuna proposed at a recent meeting.

The proposal, from the Tropical Tuna Management Advisory Committee (TTMAC), would have hiked the total allowable catch (TAC) over-catch allowance, enabling commercial fishermen to bring in yellowfin tuna above the current limits during the remainder of the 2016-17 season.

The Majority of the Tuna Catch Comes from Abundant Stocks, But Overfishing of Some Stocks Continues

September 22, 2016 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

The global commercial catch of tuna — a valuable, natural protein food source — reached 5 million tons in 2014, an increase from 4.6 million in 2013, according to the ISSF Tuna Stock Status Update – 2016 (Status of the World Fisheries for Tuna) report just published by the International Seafood Sustainability Foundation (ISSF). The report can be downloaded from the ISSF Status of the Stocks page. Tuna accounts for approximately 6% of the world’s 81.5-million-ton marine catch.

The skipjack tuna species accounted for 57% of the tuna catch, followed by yellowfin (27%), bigeye (9%), albacore (6%) and bluefin (1%). Purse seine vessels harvested 64% of the tuna, followed by longline methods (12%), pole-and-line (9%), gillnets (4%) and miscellaneous fishing gear types (11%).

The ISSF report indicates that 77% of the total volume of tuna catch worldwide in 2014 was from stocks at a “healthy level of abundance.” Previous Tuna Stock Status Update reports showed 78% of tuna catch from healthy stocks in 2014 (from a preliminary report in February 2016), 87% in 2013, 86% in 2012, and 94% in 2011.

From a perspective of tuna stocks, 44% of tuna stocks globally are at a healthy level of abundance, and 39% are overfished. Eastern Pacific Ocean (EPO) bigeye tuna, for example, continues to be slightly overfished and was downgraded from a Green (healthy abundance) rating to a Yellow (intermediate) rating since the previous February 2016 report. Other overfished stocks were Western Pacific Ocean (WPO) bigeye, Atlantic Ocean (AO) bigeye, and Indian Ocean (IO) yellowfin.

Tuna Stock Status Update also reports on tuna management measures recently enacted by tuna Regional Fisheries Management Organizations (RFMOs). Significant newly adopted measures covered in the report include the adoption by the IOTC (Indian Ocean Tuna Commission) of harvest control rules (HCRs) for skipjack tuna, as well as a plan for rebuilding the overfished IO yellowfin stock. The IATTC (Inter-American-Tropical-Tuna-Commission, in the EPO) also adopted an HCR for tropical tuna species.

“While 77% of the world’s tuna catch comes from healthy stocks, it is important to remember that there are four stocks — representing 13% of the catch — that are being overfished,” explains Dr. Victor Restrepo, ISSF Vice President, Science. “Even though there are management measures in place for them, these measures are proving to be insufficient to end overfishing — and a greater effort is required.”
