Common octopus
(Octopus vulgaris)
Overview
Octopus belong to a specialised group of molluscs, known as cephalopods, which includes cuttlefish and squid. Like all cephalopods, octopus grow rapidly, although growth rates and longevity appear highly variable and environmentally determined. For the common octopus, (Octopus vulgaris), which is distributed from western Europe to Africa, Japan and the Caribbean, biological parameters are not constant. Life span may be from as little as 12 months in the eastern Mediterranean, to 5 years in some parts of its range. Consequently, age or size at maturity, and the implications for fishery regulation of this species, should probably be locally specific. In general, common octopus are probably 8 months -2 years old when sexually mature, weighing around 500g-1.5kg (females) and slightly less for males. Octopus are solitary animals, generally inhabiting depths less than 100m, and more common in shallow water. Females lay eggs and guard them, usually dying after the eggs hatch. Egg production is relatively high at 100-500,000 eggs. Males are also thought to die shortly after reproduction. Common octopus may be identified by a double row of suckers on each arm.

Cantabrian Sea and Atlantic Iberian waters - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
Updated: November 2020
There is limited information on the population structure or stock status of common octopus in European waters. Abundance varies widely from year to year with no clear trends and is sensitive to environmental influences. There is concern over fishing pressure with reports of excessive effort, illegal fishing, exploitation of undersized octopus, and lack of effective surveillance and monitoring and control of the fishing activity in the region. Common octopus have high resilience to fishing pressure.
Small-scale fisheries land most octopuses, and the activity is mainly regulated at the regional level; the level of participation of the fishing industry in the management of their activity varies. No landings quotas are in place in the EU, or routine assessment of population to inform management decisions. A minimum landing weight is specified for common octopus in European waters. But this offers inadequate protection to the spawning stock and increases the probability of recruitment overfishing.
Towed fishing gear, particularly beam trawling, is associated with substantial damage to seabed flora and fauna, and with non-target bycatch and the discarding of juvenile fish. Octopus will generally survive trawling and may be returned to the sea alive, although bird predation on the surface may limit survival.

Generally, pot and traps have little impact on the environment. Nonetheless, there is high loss and damage of clay pots used for targeted octopus fishing, and potential for potting to disrupt sensitive habitats. Bycatch is negligible.

UK - Wild-caught
Location: UK EEZ (except Cornwall)
Capture methods: Bottom trawl (beam)
There is concern for the biomass of common octopus in the UK due to the absence of stock assessments and further biomass information, however there is no concern for fishing pressure. There are no appropriate effective management measures in place for horned octopus in UK or European waters. A Channel demersal non-quota FMP was published that incorporates both horned and common octopus. However, at the time of writing, it is too soon to know whether proposed management measures will be effective in managing the stock. Most common octopus are caught by beam trawls have significant impacts on the seabed, including damage to benthic communities and vulnerable marine habitats. They can also have high bycatch, potentially of vulnerable species.Rating last updated October 2024.
