Greenpeace today launched a new seafood campaign website, publishing its ''Red Grade'' Criteria for Unsustainable Fisheries and Aquaculture.

Greenpeace has used the criteria to create an international red list of seafood species that it has identified as being at high risk of being sourced from overfished stocks or having been caught using destructive fishing methods, or both. Greenpeace calls on companies not to trade in red-listed seafood unless they can prove that the fish stocks they source from are in a healthy state, and are not fished using destructive techniques.

Greenpeace says that the website also provides background information on the overfishing crisis and advice for industry and retailers on sustainable seafood sourcing policies.

"Global fish stocks are in crisis, and the seafood industry is fishing itself towards extinction. Retailers and processors must move to sustainable seafood purchasing policies and stop sourcing red-listed species," said Nina Thuellen, Greenpeace International Seafood Markets Campaigner. "Our seafood website provides the tools they need to do this. The international red list highlights key species they need to take action on now."

Greenpeace's international seafood red list includes 20 seafood species that it has identified as at high risk of being sourced from unsustainable fisheries, including species such as tuna, cod and shark.

Criteria for red-listing wild-caught fish include:

• The species has a life history that makes it vulnerable to overexploitation

• The species is sourced from overfished and depleted stocks, or is being fished at such high levels the stock will soon be overfished

• The fishing methods used to catch the species are highly destructive to other marine life and/or marine habitats
