Red List Category & Criteria: Least Concern ver 3.1

Assessor(s): Tous, P., Sidibe, A., Mbye, E., de Morais, L., Camara, Y.H., Adeofe, T.A., Monroe, T., Camara, K., Cissoko, K., Djiman, R., Sagna, A. & Sylla, M.
Reviewer(s): Strongin, K., Polidoro, B., Carpenter, K.E. & Corley, B.
Justification:
This species occurs in the Eastern Central Atlantic and Mediterranean. It is widespread and common. In some parts of the range it may be caught as bycatch by trawling, but it can also be found in deeper waters. As this species is often confused with P. impar, it is difficult to have clear information on population size, trend or distribution. It is listed as Least Concern.

Geographic Range [top]

Range Description:This species is present in the east Atlantic, from southern part of the North Sea and southward from Scotland to Gulf of Guinea and South Africa.

In the Mediterranean Sea it occurs all through the coastline, including the Adriatic Sea (Dulcic and Glamuzina 2006), Aegean Sea (Karakulak et al. 2006), Sea of Marmara, Black Sea (Bilecenoglu et al. 2002), Sea of Azov (Quéro et al. 1986) and east Levant (including Cyprus; Demetropoulos and Neocleous 1969, Golani 1996). Quéro et al. (1986) and Bauchot (1987) did not mention it from Egypt and Libyan coast but it is now reported from Egyptian waters (Mehanna 2007). It is also reported from Suez Canal (Ben-Tuvia 1990).

Population [top]

Population:In the Eastern Central Atlantic, this species is considered common.

In the Mediterranean, this species is often confused with P. impar. As a consequence, its distribution and population trend are difficult to estimate. In France, all specimens were later identified as P. impar. In the Levant coasts, it is not thought to be a rare species. It seems even to be the most common sole in shallow waters in the Levant coasts (mainly juveniles and sub-adults; D. Golani pers. comm.).

According to Karakulak et al. (2006), one sample was collected from a survey conducted for selectivity by gill and trammel nets in the coastal waters of Turkey from March 2004 to February 2005.

Dulcic and Glamuzina (2006) report that 15 specimens (9.8 to 30.6 cm TL) were collected using various fishing gears, in three estuaries systems in the central east Adriatic Sea.

Mehanna (2007) mention that 640 specimens (9.5 to 28.9 cm) were examined in Egyptian waters, during February 2005 and May 2005 (monthly intervals).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a benthic species, found on gravel, sand or mud at depths of five to 350 m, usually from 20-50 m. In scientific surveys in Mauritania, this species was found between nine to 93 m (Camara pers. comm. 2012). It feeds on a wide range of small marine bivalves, mainly on crustaceans such as amphipods, mysids, shrimps and decapods, bivalves and polychaetes (Quero et al. 1986).
Systems:Marine

Use and Trade [top]

Use and Trade: In some areas of the Mediterranean, this is a commercial species that is densely fished by bottom trawls, especially along Egyptian coasts.

Threats [top]

Major Threat(s): There are no major threats to this species in the Eastern Central Atlantic. It may be caught as bycatch in some parts of its range in commercial trawling. It also can have high levels of heavy metals from eating contaminated bivalves in Mauritania (Sidoumou et al. 2005).

In some areas of the Mediterranean, this is a commercial species that is densely fished by bottom trawls, especially along Egyptian coasts. The exploitation rate was found as 0.71, which is above the optimum fisheries exploitation rate of 0.50 (indicating fishing pressure; Mehanna 2007).

Conservation Actions [top]

Conservation Actions: There are no conservation measures for this species in the Eastern Central Atlantic or Mediterranean. Further studies are needed to resolve the taxonomic status and the real distribution and population trends of P. impar and P. lascaris.
