Exploited but Unevaluated: DNA Barcoding Reveals Skates and Stingrays (Chordata, Chondrichthyes) Species Landed in the Indonesian Fish Market [PDF]
Ilmu Kelautan, 2016 Reliable and precise species identification is important to fisheries management and conservation. However, many rays and skates in Indonesia are currently being exploited and landed into traditional fish market without a proper identification. Therefore,

The survival of skates (Rajidae) caught by demersal trawlers fishing in UK waters [PDF]
Fisheries Research, 2009 Skates and rays are a common component of mixed demersal fisheries, and large quantities may be discarded. Given their biological vulnerability, understanding the fate of these elasmobranchs is of management concern. Estimates of discard survival are needed for modelling the possible benefits of management measures.

Identification of Potential Essential Fish Habitats for Skates Based on Fishers’ Knowledge [PDF]
Environmental Management, 2014 Understanding of spatio-temporal patterns of sensitive fish species such as skates (Rajidae) is essential for implementation of conservation measures. With insufficient survey data available for these species in Portuguese Continental waters, this study shows that fishery-dependent data associated with fishers' knowledge can be used to identify ...

Skates in the Barents Sea: stock status and catch by fishing fleet [PDF]
, 2005 No abstracts are to be cited without prior reference to the author.Annual trawl surveys conducted by Polar Research Institute of Marine Fisheries and Oceanography (PINRO) in the Barents Sea during 1998-2003 have been used for estimation of abundance and biomass of the five species of skates (Thorny skate, Amblyraja radiata; Arctic skate, Amblyraja ...

Skating by: low energetic costs of swimming in a batoid fish [PDF]
Journal of Experimental Biology, 2016 We quantify the oxygen consumption rates and cost of transport (COT) of a benthic batoid fish, the little skate, Leucoraja erinacea, at three swimming speeds. We report that this species has the lowest mass-adjusted swimming metabolic rate measured for any elasmobranch; however, this species incurs much higher COT at approximately 5 times the lowest ...

Frontiers in Cell and Developmental Biology, 2022 Crushing and eating hard prey (durophagy) is mechanically demanding. The cartilage jaws of durophagous stingrays are known to be reinforced relative to non-durophagous relatives, with a thickened external cortex of mineralized blocks (tesserae), reinforcing struts inside the jaw (trabeculae), and pavement-like dentition.

Assessment of the conservation status of Chondrichthyans: underestimation of the pollution threat
The European Zoological Journal, 2021 Cartilaginous fish include sharks, rays, skates, sawfish, and chimaeras. Their habitat ranges from shallow coastal waters to deep ocean floors, estuarine areas as well as rivers and inland waters.

Rapid Development of Microsatellite Markers with 454 Pyrosequencing in a Vulnerable Fish, the Mottled Skate, Raja pulchra [PDF]
International Journal of Molecular Sciences, 2012 The mottled skate, Raja pulchra, is an economically valuable fish. However, due to a severe population decline, it is listed as a vulnerable species by the International Union for Conservation of Nature. To analyze its genetic structure and diversity, microsatellite markers were developed using 454 pyrosequencing.
