Well suited for fresh water and marine fish. Sold as whole cockle for the larger fish or grinded to cockle meat for the smaller ones.
The cockles are shellfish and bury themselves in sand or other sediments during low tide. They eat by opening the shell to filter out small particles of organic matter from the sea water.
