Preliminary evidence of a potential reproductive aggregation area of the common stingray Dasyatis pastinaca (Linnaeus, 1758) (Chondrichthyes - Dasyatidae) in the Central Mediterranean Sea

Shallow and coastal aggregations of batoids are poorly documented in the Mediterranean Sea, despite being likely threatened by multiple anthropogenic pressures. We report the first observations of a potential summer reproductive aggregation of the common stingray (Dasyatis pastinaca). The recurrent presence in previous years of several pregnant females, a mature male and a female with fresh bite wounds was recorded in shallow waters by recreational scuba divers and scientists in Scilla Bay (Strait of Messina, Italy), a location with unique oceanographic features in the Central Mediterranean Sea. These observations suggest that the area could be used as a parturition and mating site in early summer, and this is significant for the conservation of this Vulnerable species.

Automated summary

Shallow and coastal aggregations of batoids are not well-documented in the Mediterranean Sea, despite the potential threats they face. This study reports the first observations of a potential summer reproductive aggregation of the common stingray in Scilla Bay, Italy. The presence of pregnant females, a mature male, and a female with fresh bite wounds suggests that this area could serve as an important site for parturition and mating, highlighting the significance for conservation efforts of this Vulnerable species.
