Justification
Sepia savignyi has been assessed as Data Deficient as although it has a broad geographic range and is likely robust to localised fishery activity, recent reports of recruitment overfishing and growth overfishing in the Gulf of Suez are of concern and further research is recommended regarding fishing impacts throughout the range of this species.

Threats

Major Threats
Ocean acidification caused by increased levels of carbon dioxide in the atmosphere is potentially a threat to all cuttlefish. Studies have shown that under high pCO2 concentrations, cuttlefishes actually lay down a denser cuttlebone which is likely to negatively affect buoyancy regulation (Gutowska et al. 2010). This species is probably caught in mixed species trawls (Reid et al. 2005) in various locations. There is evidence of both growth and recruitment overfishing (Mehanna and El-Gammal 2010) in the Egyptian Gulf of Suez fishery.

Management

Conservation Actions

Conservation Actions
Mehanna and El-Gammal (2010) recommend that a minimum size limit should be imposed on the fishery to combat growth and recruitment overfishing and that action should be taken to protect the spawning stock from late February to June. Further research is recommended regarding the population trends, distribution, life history traits and threats impacting this species.
