Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA MOLLUSCA CEPHALOPODA SEPIOLOIDA SEPIIDAE

Scientific Name: Sepia dollfusi
Species Authority: Adam, 1941

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2012
Date Assessed: 2009-03-23
Assessor(s): Barratt, I. & Allcock, L.
Reviewer(s): Reid, A., Rogers, Alex & Bohm, M.
Contributor(s): Herdson, R. & Duncan, C.
Justification:
Sepia dollfusi has been assessed as Data Deficient as limited information is available concerning its population status and impacts of harvesting and even its depth range remains unknown. However there is evidence that this species is experiencing at least some fishing activity. Until the level of this activity is clarified this species cannot be accurately assessed.

Geographic Range [top]

Range Description: Sepia dollfusi occurs in the Red Sea (Reid et al. 2005). Its depth distribution range is unknown (Reid et al. 2005).
Countries:
Native:
Djibouti; Egypt (Egypt (African part), Sinai); Eritrea; Saudi Arabia; Sudan; Yemen (North Yemen, South Yemen)
FAO Marine Fishing Areas:
Native:
Indian Ocean – western

Population [top]

Population: The population size of this species is unknown.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species has a mantle length of up to 110 mm (Reid et al. 2005). Spawning locations are unknown but thought to be offshore (Gabr et al. 1999).
Systems: Marine

Use and Trade [top]

Use and Trade: Reid et al. (2005) reports that this is of no current interest to fisheries. However a gill net fishery in the main fishing port in the Suez Canal, Bitter Lake previously operated between early July and April (Gabr et al. 1999) and grey literature suggests population assessments were being conducted in the fishery as recently as 2005.

Threats [top]

Major Threat(s): Fishing activity is a possible threat to this species but insufficient data exist as to the current level of exploitation. 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).

Conservation Actions [top]

Conservation Actions: Research is required into trends in population size and the impacts of harvesting.
