These are the five best tuna companies for sustainable fishing practices

Tuna and mackerel stocks are dying out fast, as the WWF told the world last month in a new report, which demonstrated that numbers have declined 74 per cent between 1970 and the present.

Greenpeace has released its yearly tuna league tables which detail the retailers and brands who source tuna in a responsible and ethical way - and those who do not.

John West has come under fire for a very poor performance in the tables, accused of breaking a promise to consumers by continuing to use "destructive" fishing methods.

Ariana Densham, oceans campaigner at Greenpeace UK, said:

It's a great achievement that all major supermarkets in the UK now only use fully sustainable tuna in their own brand products. But John West continues to plumb the depths of irresponsibility - flooding our shelves with cheap tuna which comes at a huge cost: the indiscriminate killing of marine life.

John West responded:

We believe our commitments are best achieved by employing a number of practices and innovations all of which will work together to minimise bycatch, protect stock levels, preserve oceans, improve working conditions and ensure safe and legal practices.

See the best in the tuna league tables and what Greenpeace have to say about them, below:

The five best:

1. Waitrose: Tuna is 100 per cent sustainably caught and Waitrose is dedicated to ensuring it is fairly caught.

2. Marks & Spencer: One hundred per cent sustainably caught using pole-and-line method and strong sea to shelf traceability.

3. Sainsbury's: One hundred per cent poleand-line caught fish with strong sustainability policies.

4. Tesco: One hundred per cent pole and line caught tuna. Good traceability from sea to shelf.

5. Aldi: Strong new entrant to table, with 100 per cent sustainably caught.
