Mussel are prepared. Both marine and freshwater mussels are filter feeders; they feed on plankton and other microscopic sea creatures which are free-floating in seawater. A mussel draws water in through its incurrent siphon. The water is then brought into the branchial chamber by the actions of the cilia located on the gills for ciliary-mucus feeding. The wastewater exits through the excurrent siphon. The labial palps finally funnel the food into the mouth, where digestion begins. Marine mussels are usually found clumping together on wave-washed rocks, each attached to the rock by its byssus. The clumping habit helps hold the mussels
Short food supply chains can develop autonomous marketing strategies based on differentiation. These strategies give farmers the possibility of keeping a bigger share of the value added within the farm and within the local economies. Given these characteristics, short food supply chains are increasingly taken into consideration by rural and food policies as a driver of change in the food system and a policy tool for rural development. The analysis of short food supply chains has fed a broader debate on "alternative food chains", "alternative food networks", and "sustainable food chains". SFSCs are considered the most appropriate channels for organic and locally specific products
