Sustainably sourced seafood is hard to find, but the types of shellfish called bivalve molluscs are not only packed full of important nutrients, they’re contributing to the protection and restoration of our precious coastlines.Seafood is good for us. It’s packed full of protein, vitamins and nutrients that are essential to our health, some of which are hard to find elsewhere. But it seems finding a source of truly sustainable seafood is getting increasingly more difficult.So how do we get all those great nutrients without harming the environment? The answer could lie in the special class of shellfish known as bivalve molluscs. Bivalve molluscs include oysters, mussels, clams and scallops and are found in the intertidal zones and shallow depths of our oceans, lakes and rivers. They are filter feeders and survive on what is in the waters around them, therefore they require no feeding and they actually clean the waters in which they live.
