Abstract:This study reports the first identified potential nursery area for the critically endangered Gymnura altavela off the coast of Samandağ in the northeastern Mediterranean. Two divers conducted seasonal surveys across a total area of 750 m² at three depth intervals (5–10 m, 11–20 m, 21–30 m) using the standard underwater visual census method. Additionally, bycatch data from nearby commercial trawling operations were collected. The highest individual density recorded was 0.051 n/m² in autumn, the lowest 0.02 n/m² in summer. The findings suggest that the area functions as a nursery habitat for the G. altavela population.

Title:Identificazione di un potenziale luogo di riproduzione di Gymnura altavela nel Mar Mediterraneo nord-orientale, Turchia
Abstract:Questo studio riporta la prima area potenziale identificata come zona di riproduzione per la specie Gymnura altavela, gravemente minacciata di estinzione, al largo della costa di Samandağ, nel Mediterraneo nord-orientale. Due subacquei hanno condotto indagini stagionali su un’area totale di 750 m² a tre intervalli di profondità (5-10 m, 11-20 m, 21-30 m) utilizzando il metodo standard di censimento visivo subacqueo. Sono stati inoltre raccolti dati sulle catture accessorie delle vicine attività di pesca commerciale con reti a strascico. La densità individuale più alta registrata è stata di 0,051 n/m² in autunno, la più bassa di 0,02 n/m² in estate. I risultati suggeriscono che l’area funge da habitat di riproduzione per la popolazione di G. altavela.
