A technique in which a pit net at the top is kept open by a horizontal tube (the tree). Ticklerchains are tossed through the bottom to hunt the fish into the net.  

Biological benchmarks to determine whether fish stocks are on a good or bad level.  

A fishing method used for collecting shellfish and crustaceans from the bottom. The ship drags a steel frame with a net over the bottom, in which shellfish and crustaceans are caught. Large ships can drag multiple dredges simultaneously, on each side of the ship.  

Lift nets that are mechanically or manually picked up with a boat. Lift nets are square fishing nets attached to two crossed, bent sticks. At the place where the two sticks cross, a line is secured to pick up the net when fish are swimming above the net. To keep a lift net open, several long sticks are required on one or both sides of the boat. 

The cultivation of shellfish on shallow banks in the sea. Bottom cultivation is used to grow mussels and oysters. Due to the natural food supply in the sea, the seed of the shellfish develops into shellfish suitable for consumption.

A fishing technique whereby a pit net is pulled out through the water column by two boats. 

A variant within the gillnet fishery; the fishing gear consists of several gill nets with different mesh sizes. 

A trawl net dragged at each side or at the back of a boat over the bottom. 

Masts on which mussels are grown. Around the masts are ropes or bags wrapped with mussel seed. 

A 'birthplace' for fishing. In specially developed breeding houses, specialists ensure that fish reproduce and grow. Breeding houses only succeed when perfect conditions are met.

Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards).
