Best Fish Guide: Bigeye Tuna

 Ranking: E (Red - Worst Choice)

 What's this?

Description: Bigeye tuna is a highly migratory species that is deeper swimming than other tuna, found off the coast of the North Island for much of the year. Longline fisheries for this tuna occur mainly in the West and East Coast of the North Island from the Bay of Plenty north. New Zealand represents only 3.5 percent of the Pacific catch, which is now managed by the Western and Central Pacific Fisheries Commission (WCPFC).

Ecological concerns: Uncertainty about the state of the stocks, declining stock trend, lack of a management plan plus the bycatch of sharks, seabirds and fur seals. Bigeye is internationally listed as a threatened species (vulnerable).

Economic value: Main markets are Japan, Australia and USA. The export value in 2008 was $1.7 million.
