Selling a tuna-less future?

Page - June 1, 2011
Most Canadian supermarkets sell Clover Leaf products. The Clover Leaf label may come in various styles, with various flavours, but the tuna found inside could be from a number of stocks from around the world, caught by two main methods: longlines and purse seiners that use fish aggregating devices (FADs). Unfortunately, not only is Clover Leaf not doing enough to ensure other species aren’t killed to fill its cans, but it also is not ensuring the tuna itself comes from healthy stocks.

Two species found on Greenpeace’s Redlist- yellowfin and bigeye- are also found in Clover Leaf cans, along with the highly popular albacore tuna and the species most commonly used in canning, skipjack. Tuna carrying the Clover Leaf label could be:

  • yellowfin tuna caught by longlines and purse seine nets using FADs in the western, central and eastern Pacific Ocean and Indian Ocean
  • albacore tuna caught by longlines from the north and south Pacific, south Atlantic and Indian Oceans
  • skipjack tuna caught by purse seine nets with Fish Aggregating Devices (FADs) in the western, central and eastern Pacific Ocean and the Indian Ocean
  • bigeye tuna, likely juveniles, caught as bycatch in other tuna fisheries. A genetic testing study commissioned by Greenpeace found bigeye tuna in cans labeled as ‘light tuna’ which usually contains skipjack tuna.
