Indian Ocean Distribution of the Pelagic Stingray,

Pteroplatytrygon (Dasyatis) violacea.

Many thanks for report of pelagic stingray by Akhilesh.K.V, Central Marine Fisheries Research Institute, Cochin, India . The male specimen was caught off Cochin (9° 58' N, 76° 17 E), SW coast of India at a depth of about 100-150 m. Total length – 102 cm, disc width - 47 cm, dorsal view, ventral view. Collected by Akhilesh.K.V & Hashim Manjebrayakath in the Summer of 2008.

Correction: The Fishery Survey of India, Government of India organisation mandated to do the survey of fishery resources in the Indian EEZ is operating four research longliners and these vessels are regularly reporting this species from the Arabain Sea, Bay of Bengal and Andaman and Nicobar waters of Indian EEZ. Therefore, according to the Annual Report of the Institure for 2006-2007, the credit for the first report should go to the Fishery Survey of India. Sijo P.

Pelagic stingrays from eastern Indonesia were reported by White, W. T. and Dharmandi (2007). Species and size compositions and reproductive biology of rays (Chondrichthyes, Batoidea) caught in target and non-target fisheries in eastern Indonesia. Journal of Fish Biology 70, 1809–1837.
p . 1830 paragraph: Pteroplatytrygon violacea (Bonaparte). A total of 132 P. violacea was recorded, of which 37 were females (452–623 mm WD), 15 were males (410– 542 mm WD) and 80 counted but not sexed [Fig. 11(c)]. All of the males recorded possessed fully-calcified claspers, thus the only inference about size at maturity that could be made is that males mature at a size <410 mm WD [Fig. 11(d)]. No pregnant females or small neonates were recorded, thus the size at birth could not be determined.
