Common octopus

Common octopus has been MSC(EN) MSC:
Marine Stewardship Council, an independent, international non-profit organization that has developed an eco-label that guarantees well-managed, sustainable fisheries. Fish products that meet the criteria of the eco-label can be identified by the blue MSC logo.-certified since 2016. This fishery in northwest Spain consists of 27 boats fishing with potsWire cages:
Wire cages: a fishing method using baited wire cages, traditionally made from chicken wire, that are placed on the seabed. The cages are baited with fresh or salted fish and designed to allow target species to enter but make it difficult for them to escape. Species caught using this method include crab, lobster, whelk, Norway lobster and octopus. and trapsTraps:
Traps are a kind of cages made of, for example, chicken wire that lie on the bottom of the sea. At the front is a net with large holes, which prevents species such as seals and waterfowl from swimming into the cage.. This fishery is managed by a management plan implemented by both the local government and fishery representatives.

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.

Fishing with handlinesHandlines and pole-lines:
A collective name for pole lines, jigs and troll lines. Hand lines and pole lines are used on a small scale most of the time and are relatively selective. unwanted by-catch have a high survival rate because they can be thrown back immediately.     and pole-lines and potsWire cages:

In addition, these methods are fairly selectiveSelective fishing methods:
Selective fishing methods capture many target species, and little or no unwanted fish species and animals.    .

For octopus, there is virtually no managementManagement:
The regulations surrounding fisheries and aquaculture that ensure that production is carried out within legal frameworks and that sustainability can be assured.. 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, illegalIllegal fishing:
Fisheries that do not comply with the established agreements, such as not giving up catches to national authorities, operating without permission or in prohibited/closed zones. Illegal fishing is covered by IUU fishing (Illegal Unreported Unregulated).     fishing and misinformation by fishermen cannot be completely prevented. The managementManagement:

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 discards(EN) Discards:
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.
