Is there any type of fish you can actually eat sustainably?
Science
THE fish counter at my local supermarket has a chalkboard displaying how many different species are on sale on any given day. It is usually in the 20s, though sometimes creeps above 30. As well as staples such as cod, salmon and mackerel, it often has trout, sea bass, monkfish, langoustines, tuna, scallops, squid, catfish and flatfish.
