Overview

The common cuttlefish (Sepia officinalis) is a large commercial cephalopod that attains a mantle length (ML) of about 45 mm and a body weight of about 4 kg. They are widely distributed inhabiting the continental shelve of the East Atlantic from Mauritania to Norway and the Mediterranean Sea at depths ranging from 0 to 200 m. Cuttlefish feed on worms, molluscs, small crustaceans and cannibalism is common when prey abundances are low; and they are preyed on by other fish, marine mammals and sea birds.

 

Juvenile cuttlefish inhabit nursery grounds in estuaries and semi-enclosed coastal areas for the first year of life before migrating to deeper, offshore waters. Adult cuttlefish reproduce between spring and early summer, with some individuals maturing and spawning at the end of the first year of life, but typically most spawning activity takes place in the second year of life. Cuttlefish die after investing vast amounts of energy into a single spawning event. Fecundity is between several hundred to potentially several thousand eggs. Cuttlefish enter the fishery between 60 and 120 days of age (Challier et al., 2005) and live either one or two years.

Stock Status

less risk

more risk

Cuttlefish in Divsions VIId and VIIe has been scored a low risk. This is because the vulnerability score of 30/100 (SeaLifeBase, 2014) is relatively low compared to other cuttlefish stocks in the world and the population biomass has been relatively stable throughout the time-series.

Management

less risk

more risk

The management of cuttlefish in Divisions VIId and VIIe has been scored a moderate risk. This is because there are some management measures in place to protect the stock from overexploitation, but the effectiveness of these measures remains unclear.  Cuttlefish in Divisions VIId and VIIe have been assessed since 2013, and the assessment is based on both fishery-dependent and fishery-independent data.

Bycatch

less risk

more risk

The bycatch risk of this fishery has been scored low risk. This is because the bycatch in pot cuttlefish fishery is considered to be negligible compared to other fisheries.   Catch of protected, endangered and threatened species is minimal.  “Ghost fishing” by lost pots is not considered to be a problem.

Habitat

less risk

more risk

The habitat risk of this fishery has been scored a low risk. This is because traps, although positioned on the sea bed, do not move across it and therefore do not damage sea floor habitats.  In addition, there are spatial restrictions, prohibiting the setting of traps in vulnerable or conservation areas.

Outlook

Current risk status Outlook Reason
Stock status Low Stable This  is because the stock is fluctuating without any historical trend, there is no discernable stock-recruitment (that is relationship between numbers of adults and offspring) relationship, and the stock is currently in good condition.
Stock management Moderate improving Stock assessment has recently commenced, and will be continued on an annual basis. Blim is defined as the minimum observed biomass during the studied period (ca. 10,000 t). The fishery is rigorously managed off French shores, but isn’t in U.K. waters, although, the main spawning ground off Torbay is partially protected by overlapping with an MCZ area.
Bycatch Low Improving Bycatch is negligible in trap fishery.
Habitat Low Stable Pots result in low habitat impact.
