Analysis of fisheries that catch octopus in Chinese and Southeast Asian fisheries is complex, as octopus is caught in a number of different fisheries managed by different countries. These fisheries catch a wide range of species, including species of octopus, squid and finfish. In addition, accessing reports is problematic and the quality of management varies across the region. China also has a large distant water fishing fleet, which means that the vessels fish around the world, not just in waters bordering their country.

Regional assessments of fisheries in Southeast Asia indicates that in general, high fishing pressure on a range of species, including octopus species, in coastal waters has led to declining catches across the region, with many species of octopus now overfished. Whereas fishing effort was previously concentrated in coastal waters, overfishing has pushed fisheries further offshore, transferring fishing pressure to deeper water species. It is not clear from available reports what management actions have been implemented to allow stocks of overfished octopus to recover. Issues of under-reporting of the amount of octopus (and other species) caught in the Chinese fisheries have also been identified, and there is minimal monitoring and management of this fleet.

There is generally weak management to ensure that overfishing is not occurring, as well as a lack of information on the volume of octopus landed in any of these regions.

Octopus is mainly caught using trawl fishing gear. Studies have identified that trawling for octopus and squid has damaged large areas of coral reef habitat in parts of Southeast Asia. For example, around 80% of corals in Thai waters have been damaged or destroyed as a result of fishing gear impacts, although it is not clear what proportion of this is as a result of trawling for octopus.

In regional assessments of fishing impacts, trawl fishing has been identified as a key threat to a number of different species of vulnerable marine wildlife, including dugongs and turtles. Dugong populations have been decimated to the point of local extinction in some areas, and green, hawksbill and olive ridley turtles are caught in trawl fisheries in Vietnam, Malaysia and Thailand. Whilst there have been improvements in fisheries management in recent years, it is not yet clear whether efforts to reduce mortality of threatened species have been successful.
