Size of a fish stock needed to maintain the species/stock in the long term.

A fishing technique whereby a net with a long line (the seagulls) is pulled through the water on both sides. The ship is slowly steaming forward when getting in. Also called flyshooting

A cultivation technique whereby young fish is caught in the wild, then cultivated in cages in the sea for consumption. 

The negative effects on the seabed, caused by certain fishing gear and fisheries. 

The Sustainable Eel Group (SEG) is an international organisation that aims to contribute to the recovery of eels in Europe. The SEG has developed a European standard and certification programme for sustainable eel called the Sustainable Eel Standard (SES).Demonstrating that a fishery or farm is actually making this positive contribution is not easy. In addition, a certification such as this only makes sense if there is no further eel fishing. After all, non-certified parties, who do not have to comply with the SEG rules, would be allowed to continue fishing.

A fishing technique to target schools of fish in the water column. The seine consists of a vertical standing net with a long line on each side. By making an outflanking movement, the fish is enclosed into the net.  

Selection panels ensure that unwanted by-catch species are routed out of the net.

Selective fishing gear catches many target species, and little or no unwanted fish species and animals. 

Selective fishing methods capture many target species, and little or no unwanted fish species and animals.  

A fishing method whereby an anchored long main line (40-100 km long) is expanded, with attached transverse lines with hooks with bait.  

Lift nets that are mechanically or manually collected from static platforms along the coast or river banks. Lift nets are squarely 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 is swimming above the net. The fish is sometimes attracted with the use of light or bait. 

A beam trawl that uses ropes with rubber spools, instead of tickler chains. 

Selectivity nets used in shrimp dredges to limit by-catch of larger specimens and species, such as sole and plaice.  

The reproductive behaviour of fish.  

Areas where fish reproduce. 

The number of species and the ratio between the species numbers in a habitat.  

The fish of a particular species reproducing in the same area in the same period. 

Based on data about fish catch of fishermen and samples conducted with research vessels, a stock assessment describes the current and former status of a fishery stock. The size of the stock will be measured and a prediction will be made about how the stock will respond to management measures.

Determining the number of fish of a particular species who are reproducing in the same spawning area in the same period. 

Estimating the number of fish of a particular species who are reproducing in the same spawning area in the same period.  

An experimental beam trawl method whereby the heavy beam is replaced by floating wings. 

Meeting the needs of current generations without compromising opportunities for future generations. This also allows future generations to benefit from the same needs.
