Rays and wedgefishes are among landed chondrichthyes in most Southeast<br />

Asian fisheries. They are increasingly exploited for meat as protein source and<br />

skin as leather. A bimonthly landing port surveys in Pulau Kambing, Kuala<br />

Terengganu, was conducted between May 2017 and February 2018 to study<br />

temporal distribution and diversity of these groups. A total of 357 specimens<br />

represented 13 ray species and one wedgefish species were identified, weighed<br />

and measured total length. Seven species were first records to Terengganu<br />

waters within families Dasyatidae, Gymnuridae and Myliobatidae. Three species<br />

were Near Threaten, eight were Vulnerable, and three were classified as Data<br />

Deficient according to IUCN RedList. Several landed specimens were juvenile<br />

sizes (Butterfly ray and Whipray). Bycatch in trawling nets increased species<br />

landings due to demand and sold for affordable prices. Efforts are needed to<br />

monitor species landings for management scheme implementation to prevent<br />

decline or local extinction for long term.<br />
