According to this article some supermarkets will soon be offering incentives to customers to try and make them switch to sustainable fish. On Friday Sainsbury’s will be offering free samples of lesser know species to customer who request one of the so called “Big Five” fish, cod, haddock, tuna, salmon and prawns. Marks and Spencer will be promoting the use of sustainable alternatives in its ready meals and in frozen foods. Among the alternatives promoted will be coley, pouting, megrim, rainbow trout and mackerel. It will be interesting to see whether the promotion changes people’s buying habits. It seems most people are put off trying different types of fish mainly because they do not know how to cook them. Perhaps, supermarkets should be looking at adding recipe ideas alongside the fish counter to highlight what can be done with them.
