Assessment Information [top]

Red List Category & Criteria:

Critically Endangered A2abc+3cd ver 3.1

Year Published:

2005

Assessor/s:

Cook, S.F. & Compagno, L.J.V.

Reviewer/s:

Justification:
This assessment is based on the information published in the 2005 shark status survey (Fowler et al. 2005).

The Common Sawfish (Pristis pristis) is a large species of sawfish that was once common in the Mediterranean and Eastern Atlantic. It has been extirpated from the Mediterranean and European sections of its range and is believed to be severely depleted in Africa.

History:

2000	–	Critically Endangered
1996	–	Endangered

Geographic Range [top]

Range Description:	A sketchily-known large sawfish of the Mediterranean (where it no longer occurs) and eastern Atlantic. It has been recorded from Portugal south to Angola and possibly to Namibia (Fowler 1936, Bigelow and Schroeder 1953b, Krefft and Stehmann 1973, Stehmann and Burkel 1984, Stehmann 1990, Compagno and Cook 1995a). Freshwater records of Common Sawfish are from Mali or Senegal in the Faleme River and possibly Gambia in the Gambia River (Compagno and Cook 1995a).
Countries:	Native: Angola; Benin; Cameroon; Congo; Côte d'Ivoire; Equatorial Guinea; Gabon; Gambia; Ghana; Guinea-Bissau; Liberia; Morocco; Nigeria; Panama; Portugal; Senegal; Sierra Leone; Togo; Western Sahara
FAO Marine Fishing Areas:	Native: Atlantic – northeast; Atlantic – eastern central; Mediterranean and Black Sea; Pacific – southeast

Habitat and Ecology [top]

Habitat and Ecology:	Very little is known of this misnamed sawfish, which is actually quite rare. All sawfishes are ovoviviparous, but little else is known of the reproductive biology of the Common Sawfish. Its size at maturity is unknown, but its maximum length is about 5 m. Mature specimens are generally lacking in collections, small specimens are rare and isolated saws attributed to the species may be misidentified members of the Pristis microdon group. Virtually all aspects of its biology could benefit from additional field collections and museum preparations.
Systems:	Freshwater; Marine

Threats [top]

Major Threat(s):	Common sawfish is presumably caught in inshore fisheries with net and line gear set for other species. It lives in places subject to heavy artisanal and commercial fisheries and will tend to be taken incidentally wherever it occurs. Some West African populations of sawfishes have recently been heavily depleted as a result of increased coastal elasmobranch fisheries effort (Mathieu Ducroq in litt.).

Conservation Actions [top]

Conservation Actions:	There are currently no management or conservation measures in place for this species. All species of Pristidae have been listed under Appendix I of CITES (2007), except Pristis microdon which is listed under Appendix II (comment added by LRH May 27th 2010).
