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 potspots:
A fishing method in which traps made of chicken wire are baited (fresh or salted fish) which are then placed on the seabed. Species caught this way include crab, lobster, whelk, langoustine 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. has virtually no impact on the seafloor. 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:
The regulations surrounding fisheries and aquaculture that ensure that production is carried out within legal frameworks and that sustainability can be assured. of this species is not effective.
