Because octopuses grow and reproduce rapidly, they are not very sensitive to overfishingOverfishing:
There is so much fish caught that the size of the stock has diminished 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. . Nevertheless, they 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 many places and a decline in the size of the stockStock:
The fish of a particular species reproducing in the same area in the same period. can be observed. It remains difficult to determine an octopus stock because they hide in rock crevices. Because octopuses spawn in schools, they are easy to catch, which makes them sensitive to fishing.
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 can have many impacts on endangered and protectedProtected species:
Many marine species are protected from deliberate or intentional disturbance, capture, injury and killing, and in some cases possession or sale. Species are often protected if they play an important role in the ecosystem or are sensitive to fishing. These marine species are protected regardless of whether they are inside or outside marine protected areas. species by being caught as 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). . Demersal fisheries often have high numbers of discardsDiscards:
Unwanted by-catch, which is thrown back because there is no quota, the market price is too low, or the fish is below the legal minimum landing size. Discards can be alive or dead. by catching unwanted or undersizedUndersized fish:
Fish smaller than a prescribed minimum size. These sizes are determined per species and per country. For Europe, a minimum landing size applies to all EU Member States. species.
For octopus, there is virtually no management. However, because of its economic and ecological value, it is desirable. National and local regulations have been established in certain places, which is reasonably effective. Unfortunately, illegal fishing and misinformation by fishermen cannot be completely prevented. The management of this species is not effective.
