The fishing pressureFishing pressure:
Fishing pressure is a result of the fishing effort/amount of fishing on a stock, which determines the fishing mortality. Fishing mortality is the share of the fish stock that dies annually as a result of fishing. on blue (swim) crab is currently to high. The stockStock:
The fish of a particular species reproducing in the same area in the same period. of P. trituberculatus in this area is being overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. . Due to the short lifespan of the crab and their fast reproduction cycle, there is a chance that the stock will have a relatively fast recovery.
The use of fykeFyke:
A fishing technique where fish are attracted into a fyke. Fykes are pots or traps made of, for example, wire mesh.s, potsPots/clay pots:
Clay pots are used in southern Europe to catch octopus. The animals crawl into the pots to use it as shelter, after which the fisherman collects the pots. This is a selective fishing method that does not damage the soil. and traps have no negative impacts on the ecosystem. Although, it is thought this method has a relatively large impact on vulnerable and threatened species. The use of demersalDemersal otter trawls:
A technique in which conical nets are dragged over the ground and are held open by large, square 'otter planks'. The planks also work as a plough, in which fish are hunted into the nets. otter trawls does have a negative impact on the sea bottom. The use of driftDrift nets:
Gill nets that float on the sea current (with or without boat). Fish get stuck in the nets with their gills. Drift nets are prohibited in European waters. nets has a potentially large impact on vulnerable species. This method has a high bycatchBycatch:
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). percentage.
Currently, there is no management plan for this species and the current policy is not sufficient enough to protect this species. There are also no signs of the development of a new management plan on the short term.
Fish in season
Fish is in season when the spawning period has ended, as the quality is then at its best.
