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

Abstract

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.

Assessing the relevance of sharks and rays for Mediterranean EU fisheries to support a transition from species exploitation to species conservation

“…For example, increasing efforts are being made to delineate nursery grounds and other essential sh habitats, such as areas where spawning or mating aggregations occur; this growing body of knowledge could support the establishment of conservation measures for threatened elasmobranchs (e.g. Colloca Grancagnolo et al 2023). In this direction, the "Important Shark and Ray Areas" (ISRAs) initiative (Jabado et al 2023), supported by the Shark Specialist Group of the IUCN Species Survival Commission, aims to delineate critical habitats/areas for protection.…”
