Green Sawfish, Pristis zijsron Bleeker 1851

More Info

Distribution	Widespread across northern Australia, from about Eighty Mile Beach, Western Australia, to the Cairns region, Queensland. Historically, individuals were taken as far south as Sydney, New South Wales. Elsewhere, the species occurs in the tropical Indo-west Pacific. Historically, the species was widespread in the Indo-West Pacific from southern Africa to Australia and Taiwan, including the Red Sea, Persian (Arabian) Gulf and some of the Indian Ocean islands. Green Sawfish inhabit coastal marine and estuarine waters, with adults more common offshore in depths to >70 metres. Significant pupping grounds have been identified in the southern Pilbara region of Western Australia.
Feeding	Feeds mostly on bony fishes and crustaceans, stunning and killing their prey with the saw-like rostrum.
Biology	The life history of the Green Sawfish is poorly known.
Fisheries	Populations have historically been affected by inshore commercial net and trawl fisheries throughout most of the distribution range, resulting in population declines.
Conservation	EPBC Act 1999 : Vulnerable IUCN Red List : Critically Endangered NSW Fisheries Management Act 1994: Endangered CITES Listed : Appendix I Throughout its range, the Green Sawfish has historically been targeted or taken as incidental bycatch in commercial and recreational fisheries. The rostrum with the large teeth is easily entangled in nets, including in shark control nets. Captured sawfish are retained in many parts of the world due to the high value of their fins, rostrum and meat. Green Sawfish are fully protected in Australia.
