SHOPPERS across the country are being urged to protect the oceans by following the advice of a new fish-buying guide produced by a Herefordshire charity.

Under-threat species such as cod (pictured right) have all been listed in a publication by the Ross-on-Wye-based Marine Conservation Society (MCS).

The charity outlines fish to avoid and fish to eat based on current scientific assessments of stocks. The guide is available free on www.FISHonline.org

The MCS wants people to avoid shark and deepwater fish, but not everything is off the menu - we can continue eating the traditional favourites such as cod and haddock - although from sustainable fisheries - as well as mussels, oysters, Alaskan salmon and scallops.

"Consumers can make a real difference to the way our fish sticks are managed and help stop the present decline," said Bernadette Clarke, MCS fisheries officer.

"By only choosing fish from healthy, responsibly managed sources, caught using methods which minimise damage to the marine environment and other species, consumers can create a market for sustainably managed and selectively caught fish."
