This stingray occurs in the eastern Atlantic and Mediterranean Sea. It occurs from the shore to about 200 m depth, but is more commonly found in shallow waters (<50 m). This depth distribution makes it more vulnerable to small-scale inshore fisheries than to offshore trawling. For example, Dasyatis pastinaca made up more than 40% of the elasmobranch biomass captured in the trammel net fishery off the Balearic Islands. In the northeast Atlantic, it is a less common species, generally showing a low abundance index in comparison to the Mediterranean Sea and may have disappeared from the south of the Bay of Biscay. Data from comparative trawl surveys (1948 and 1998) conducted in the Adriatic Sea suggest that this species may have decreased in abundance. Although few data are available, this species appears to be less common than it once was in the Mediterranean and Northeast Atlantic. It is currently assessed as Near Threatened there and further investigation is required into catches and the taxonomic status of population throughout this species' global distribution before it can be assessed beyond Data Deficient globally.

Geographic Range [top]

Range Description:Eastern Atlantic: from southern Norway and the UK to South Africa, including the Canary Islands, Madeira, western Baltic Sea, Mediterranean Sea, Black Sea and Sea of Marmara (Bilecenoglu et al. 2002, Serena 2005). In Celtic Seas this species is regarded as a vagrant from more southern waters (ICES 2005a). The few observations of this species in the North Sea are restricted to Shetland waters and the southern North Sea, where they are occasionally caught in inshore surveys (ICES 2005b). This ray has a higher presence in the western-central Mediterranean area (coasts of Morocco, Spain, France, Tyrrhenian, Corsica, Sardinia and Sicily) than elsewhere in the Mediterranean region (Baino et al. 2001).

Population [top]

There is no information on the size of the population of this species within the Mediterranean, however the Mediterranean International Trawl Surveys (MEDITS) from 1994-1999 revealed a low frequency of occurrence for D. pastinaca. It appeared in 49 hauls, which was only 0.5% of the total number of hauls, but these surveys only sampled depths from 50-800 m and this species is more common in shallow waters <50 m depth. Comparative trawl surveys conducted in 1948 (Hvar) and 1998 (MEDITS) in the Adriatic Sea (both up to 400 m depth) suggest that the abundance of D. pastinaca may have decreased during this period. The frequency of occurrence (frequency log transformed data) of D. pastinaca on the shelf according to the 1948 survey was ~0.5, whereas frequency of occurrence on the shelf in the 1998 survey was <0.1 (Jukic-Peladic et al. 2001).

Northeast Atlantic
In the Northeast Atlantic the common stingray is clearly less abundant than in the Mediterranean. D. pastinaca has reportedly disappeared from the Bay of Biscay (Quero1998), as observed for other demersal elasmobranch species. The average catch rate for this species caught during the quarter 1 IBTS in the North Sea, Skagerrak and Kattegat is 0.0006 (number per hour, 1977-2004) (ICES 2005b). Within UK groundfish surveys, Dasyatis pastinaca was only recorded occasionally in the western English Channel at depths of 17-160 m (Ellis et al. 2005).

Habitat and Ecology [top]

Habitat and Ecology:Dasyatis pastinaca is a demersal brackish to marine water species, found over sandy and muddy bottoms from shallow waters to a depth of approximately 200 m (Whitehead et al. 1984), although it seems to be most abundant in inshore waters. Bottom trawl surveys in the Mediterranean Sea suggest that it is more common in waters <50 m depth (Morey et al. In review, Massuti and Moranta 2003, Relini et al. 2000). This species can sometimes inhabit areas close to estuaries and over rocky reefs. Depth distribution of the biomass index shows values of 1-10 kg/km² between depths of 0-100 m, and 0.1-1 kg/km² at depths of 100-200 m (Baino et al. 2001).

D. pastinaca reaches a maximum reported size of 140 cm disc width (DW) and 250 cm total length (TL) (Bauchot 1987, Fisher et al. 1987, Notarbartolo and Bianchi 1998). The size at maturity of females is estimated at about 38 cm DW (Capape et al. 1996) and 60 cm TL/28 cm DW (Ismen 2003). Males mature at a smaller size, estimates ranging from 32 cm DW (Capape et al. 1996) and 50 cm TL/26 cm DW (Ismen 2003). The age at maturity and longevity of this species is unknown.

Females reproduce twice a year (Notarbartolo and Bianchi 1998), however the reproductive age and period of gestation is unknown. In the northern Adriatic, reproduction takes place between September and May, during which pregnant females approach the coast. Bini (1967) reported that pupping occurred between July and August, and 4-9 pups/litter are produced (Notarbartolo and Bianchi 1998). Several localities where the species aggregates during mid June and July are known in the Balearic Islands. These aggregations of mature stingrays are probably related to reproduction (Morey et al. in review.). Young specimens are common in shallow waters over sandy bottoms, and parturition was reported to occur in early July in the eastern Mediterranean (Ismen 2003). Neonates are approximately 20 cm TL (8 cm DW) (Ismen 2003). The rate of population increase and natural mortality are unknown.

D. pastinaca feed mainly on demersal and benthic animals, such as crustaceans, cephalopods, clams, polychaetes and fish (Notarbartolo and Bianchi 1998, Whitehead et al. 1984). In a study by Ismen (2003), crustaceans represented more than 99% of the diet when pooling all size classes, but teleost fish were of increasing importance in the diet of larger stingrays.

Threats [top]

Major Threat(s): This species is taken as bycatch and is sometimes targeted in semi-industrial, small-scale and commercial bottom trawl, gillnet, beach seine, bottom longline and trammelnet fisheries. Commercial fishermen often cut off the tails of stingrays following capture and prior to discarding, although it is unclear as to how this affects discard survival (Notarbartolo and Bianchi 1998). Little data are available on catches as a result of discarding at sea. The species' preference for shallow waters (<50 m) makes it more vulnerable to small-scale inshore fisheries than to offshore trawling. For example, D. pastinaca made up more than 40% of the elasmobranch biomass captured in the trammel net fishery off the Balearic Islands (Morey et al. in review.). Small scale fisheries operating within this species' shallow water range in the Mediterranean Sea and Atlantic make up an important component of the European fishing fleet (Stergiou et al. 2006). This species was not recorded in recent (1999-2000) experimental fishing trials with trammel nets conducted within several parts of this species' known range in the Mediterranean and northeast Atlantic (Stergiou et al. 2006). There is a ban on trawling within 3 nm of the coast for EU countries, however there are some exceptions to this, and both legal and illegal trawling continues to occur in shallow waters in parts of the northern Mediterranean Sea.

Important grounds for reproduction (mating, parturition, nursery areas) seem to be associated with shallow sandy bottoms, which human disturbance (e.g. tourism activities on beaches) or fishing pressure (trammel and gillnets targeting cuttlefish, mullets, bass and flatfishes, and trawling) impact.

Conservation Actions [top]

Conservation Actions: D. pastinaca is protected within five of the six existing Balearic Island marine reserves. Although artisanal fishing is allowed within these marine protected areas (MPAs), these stingrays must be released alive if caught. Accurate monitoring of artisanal catch in those areas where the species is very commonly taken is needed to provide information on the size of the population.
