Go to your local super market fish counter and ask them if they get fresh whole salmons in. If yes, ask them for the container. They are big and deep with large enough holes at two of the sides great for drainage. The salmon containers are usually free. Wm.Morrisons are usually happy to give the containers away...other supermarkets may charge. When finished with the polystyrene salmon container, it easily breaks up to dispose of in your ordinary refuse bin.
