Whale and Dolphin Conservation Society 'Dolphin Friendly' tuna correspondence, 1990

Correspondence relating to the Whale and Dolphin Conservation Society's scheme for accrediting tuna as 'dolphin friendly'. Certain forms of tuna fishing had resulted in the killing of dolphins, which had become a matter of public concern. Sainsbury's Tuna at this time was the only brand of tuna to be approved of as dolphin friendly by the Society. This correspondence relates to a proposed agreement regarding the rules for 'dolphin friendly' labelling.
