True conservationists understand that sustainability will come from eliminating threats such as illegal fishing, and a lack of enforcement of compliance with conservation measures.
UK retailers and processors have been pressured to provide only pole-and-line caught tuna. However, it is possible to buy unsustainable pole-and-line tuna if small, non-targeted tunas are taken from stocks that can't support the added pressure, if some of the catch is wasted due to poor fish handling or if a vessel's carbon emissions aren't understood, if the stock fished itself is not properly managed.
If we buy into such a simple myth today about tuna, the species won't be any further down the path towards sustainability.
