The traditional method of cultivating mussels in Galicia is by using a system called “Batea”, this method is known to be one of the best as it gives a higher yield of live mussels. Galicia in Spain produces about half of the entire production of mussels around the world. The “Batea” method is a rectangular floating platform which has a maximum surface area of 500m2 is made out of eucalyptus beam fastened on top of 4 or 6 barrels or floaters anchored to the sea bed. On this platform hanging down into the water there are a maximum of 500 ropes measuring no more than 12 metres long. The eggs of the mussel are placed on this ropes which will remain totally submerged until the growing mussels attain their commercial weight. Once the weight of the rope reaches about 100kg, this weight is then divided into other 3 ropes of about 30kg each. Both marine and freshwater mussels are filter feeders that feed on plankton and other microscopic sea creatures. They do so by drawing water in through their incurrent siphon. The water is then brought into the branchial chamber by the actions of the cilia located on the gills for cilliary-mucus feeding. The wastewater exits out through the excurrent siphon. The labial palps finally funnel the food into the mouth where digestion can continue.
