Squid & Octopuses

Squid and octopuses belong to the group of cephalopods (Cephalopoda). Two distinct species can be found, the octopuses (eight-legged) and the squids (ten-legged). European squid and cuttlefish are most common in the Northsea. Although, squid are physically related to snails and shellfish their ‘lifestyle’ is more similar to that of fish. Many squids species swim in large groups and undertake vast seasonal migrations. Squids lay eggs in the mid-water column and hunt for fish and are food for larger fish and sea mammals. Octopuses often occur more on the seabed.

Cuttlefish

Cuttlefish, common cuttlefish or European common cuttlefish, live close to the seabed. They have 8 tentacles with two longer tentacles in between to catch pray. Cuttlefish forage at night for crabs and shrimp. Cuttlefish are masters of camouflage and can change their colours to blend in with the environment. It has an internal oval shaped shell instead of bones. These shells can be found washed upon shores and are often eaten by birds for calcium. Cuttlefish swim with a sifo: an internal cavity that creates a jet of water that pushes the cuttlefish backwards and enables it to swim. Cuttlefish reach on average 30 cm in length and have a short life span of 3 years.

Final assessment

Explanation assessment

There is not much known about the common cuttlefish. The few data suggest a decline of the stockStock:
The fish of a particular species reproducing in the same area in the same period. . The common cuttlefish has a short lifecycle and grows fast. They are a bit susceptible to fishing pressure because they spawn in schools.

The focused fishery on cuttlefish with cuttlefish pots is selective and does not damage the seabed. Occasional 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). has a high survivability.

The cuttlefish is included in the Common Fishery Policy of the EU. Measures are being taken for catch limits, but that is not effective enough. Management is difficult due to the lack of information about stock size and about the amount of cuttlefish that is caught.
