A management plan describes the management measures (such as catch limits) and their evaluation for one or more fisheries.
A fishing method using mechanized dredges to dig and rinse mussels and other shellfish from the bottom. Dredges are steel frames to which a net is attached. On the front of this frame, steel points are often attached that act like a kind of rake. Suction dredges suck the shell fish from the sand into the boat.
A collective name for pole lines, jigs and trolls. Jigs make use of lines with artificial bait that are moved up and down to imitate a prey.

Marine Protected Areas are protected areas on seas, oceans, estuaries or large lakes, where application functions that have a negative impact on marine values, are restricted or prohibited.
Marine Stewardship Council, an independent, international non-profit organization that has developed an eco-label that guarantees well-managed, sustainable fisheries. Fish products that meet the criteria of the eco-label can be identified by the blue MSC logo.
An assessment process a fishery has to get done, to obtain certification by the Marine Stewardship Council.
Fisheries that comply with the Marine Stewardship Council assessment criteria and are certified. Fish products with the blue MSC label are caught by sustainable fisheries.
Theoretically the greatest possible 'safe' catch, in which fish populations have sufficient size to reproduce in the long term.
Mussel seed capture system, or 'mosselzaadvanginstallatie' in Dutch (MZI), is a specialized system used to caputre mussel seed from the watercolumn. The systems use ropes hanging in the water colum on which mussels seed attach. The ropes are attached to an anker below and floating devices above.
