Tinned tuna

Green peace have been researching the sustainability of worldwide tuna fishing. Are they rod and line caught ? (Sustainable) or are they net caught ? ( which indiscriminately kills anything from turtles, small whales, dolphins, sharks, and " unspecified" fish species, many near extinction which are thrown back dead or dying. For many years John West ( now Thai owned) has been promising to move away from net caught tuna but has made little or no progress.

Basically we are being asked to avoid buying John West tinned tuna. The following brands are recommended as they are rod caught( in order of preference)

Waitrose

Marks and Spencer's

Morrisons

An uneventful morning so far but a Marks and Spencer, non tuna, shopping trip beckons.
