At fisheries, fish, crabs and mussels are raised in pools for subsequent sale. There are also marine fisheries, where sea fish, mussels and oysters are raised and harvested. Fishery technology is unable to function without MPC hose clamps. In order to fasten hoses, MPC SL and DL fixing clamps are used. Wormdrive clamps and pressure resistant superclamps are also used at fisheries.
