Lobsters and crayfish

Lobsters live in saltwater whilst crayfish live in freshwater habitats. Lobsters and crayfish are most often caught using pots or traps. Most lobsters are equipped with ten legs and two scissors as front legs. With these scissors, they are able to grab, cut or crack their food. Did you know lobsters and crayfish, just lie snakes, change their skin because their shell does not grow with their bodies? After changing their shell the animal grows fast and increases in weight.

There are many different lobster species. Most common are the American lobster in the north-western Atlantic ocean, and the European lobster in the north-eastern Atlantic ocean. Lobsters have a relatively slow growth rate and reach sexual maturity at a late age. Another frequently consumed lobster is the Norway lobster. This species is way smaller than the American and European lobster. This species occurs in the north-eastern Atlantic Ocean and parts of the Mediterranean sea.

Spiny lobster

The spiny lobster closely resembles the true lobster but does not have large claws. It does have to very long antennas on its head. There are many species of spiny lobster that are sold on the Dutch market, that mainly come from the eastern Atlantic Ocean, the Mediterranean, and the western Indian Ocean. Spiny lobsters usually reach lengths of 20 to 40 centimetres.

Final assessment

Explanation assessment

Several species of spiny lobster are targeted commercially. 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. is high and crawfish are 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. in most places.

These species are caught mainly with anchoredanchored gillnets:
A fishing technique whereby passing fish become tangled up in a net with their gills (also known as a gillnet), which is vertically standing on the bottom. gillnets and bottomBottom trawls:
A fishing technique in which cone-shaped nets terminating in a codend are dragged through the water column or along the bottom. trawls. Both fishing methods have high levels of 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). , including of sea turtles and endangered shark species.
