Pret a Manger has banned bluefin tuna from its menu Times Newspapers Ltd

It has already prompted Pret A Manger to take tuna sushi off its shelves and Wagamama to remove blue marlin from the menu, and this weekend it was the turn of consumers to react to its shocking message.

Review: The End Of The Line

The End of the Line, the documentary which claims we will soon have caught every fish in the sea, appalled audiences when it opened in cinemas this weekend.

Described as “the Inconvenient Truth of the ocean”, Charles Clover’s investigative documentary predicts that, if overfishing continues, we will have wiped out all seafood by 2048. The film confronts politicians and restaurants such as Nobu which serve endangered species such as bluefin tuna.

It claims not only do the huge nets used in commercial fishing cause large-scale waste and overfishing, but that even supposedly more ethical methods of fishing, such as growing salmon in special fish farms, are extremely harmful.

Audiences at London’s Panton Street Odeon were horrified at the film’s revelations and many vowed to reduce the amount of fish they eat.

“I was amazed at how rich countries are stealing food from the poor to sustain profits. It made me ashamed to be part of the EU. I already buy only line-caught, marine-certified fish.”

Jamie Dickson, 33, Hackney, journalist

“I was brought up eating lots of fish, but I have now cut out tuna, and I’ll be thinking about cutting out farmed salmon having seen the film. I’ll only be buying line-caught salmon and dive-caught scallops.”

Robyn Manley, 25, Golders Green, biologist

“I knew some of the ethical concerns about fishing, but the film opened my eyes even more. When they buy a can of tuna, people don’t care how it was sourced – they see two-for-one deals and buy fish in bulk."

Tilly Sims, 23, Elephant and Castle, charity worker

“I think the public will respond if they watch the film. I eat a fair amount of fish, and I will be looking for locally produced and sustainable fish in future. The film made me realise just how vigilant I need to be.”

Diana Randall, Chelsea, therapist

“It was an interesting and powerful film. It needs to be put on national TV so people are educated and can change their buying habits. I will be extremely careful to buy more sustainable fish.”

Lucy Collier, 15, Teddington, student

“It showed the messy side of the industry, which was good. However, the ending made you feel like if we all cut back on the odd tin of tuna then everything will be fine. There’s so much we need to do.”

David Collier, 46, Teddington, environment manager

“People go for food that’s cheap, and so unless laws are enforced there will be no change. There’s 6.5 billion people to feed, and few can afford line-caught haddock from Waitrose.”
