Tuna

The tuna is a migrating fish, which means that the fish crosses many national waters. There are several species, like skipjack, yellow fin, albacore, and blue fin, and a big difference exists between fresh or frozen tuna and canned tuna.

Did you know…

  • The blue fin tuna, for instance, has been an endangered species for years

  • Tuna normally is not eaten or caught by the local population. One of the reasons is that tuna does not swim near the shore

Production chain

Most tuna species are caught in wild by using several methods like, purse seining, pole and line and long lining. Catching tuna species occurs all over the world. In the Mediterranean Sea the blue fin tuna is caught as a juvenile and are hatched in ranches. Fresh, frozen and canned tuna then undergo several processing steps, such as: gilling, gutting, heading pre-cooking, freezing and loining. It is common to undertake all the processing stages up to tuna loining as close as possible to the landing areas in developing countries.

Problems

Overfishing and by-catch, which happen both in normal tuna fishing and in Illegal, Unreported, Unregulated fishing (IUU fishing), are important and well-known problems in the tuna sector. This causes depletion of fish-stocks and harms biodiversity. Every year, a fleet of fishing vessels race to catch the fish at the most important and vulnerable stage of their life cycle. The fishing fleets catch well beyond the levels allowed by the quota, and much of the fish caught is too young not having the chance to breed and therefore repopulate the diminishing stocks. The International Labour Organization (ILO) has assigned fishing as the most dangerous profession in the world. Especially in Asia the conditions on board of vessels that catch tuna and other fish are dangerous. Fish pirates (IUU fishing) especially do not follow the regulations leading to hazardous working conditions. Coupled with the risk of the activity are the very long working hours and extensive contracts. The average wage rates for cannery workers in Southeast Asian countries is less than €0,25 per hour. In tuna canneries in Papua New Guinea the weekly earnings of a worker based on 47 hours a week could amount to €12.The right to form and join a trade union is not recognized in tuna producing countries such as the Maldives. In this country there are no unions since there is no legal protection from anti-union discrimination.
