Shark depredation and behavioural interactions with fishing gear in a recreational fishery in Western Australia

Shark depredation and behavioural interactions with fishing gear in a recreational fishery in Western Australia J. D. Mitchell, D. L. McLean, S. P. Collin, T. J. Langlois ABSTRACT: Shark depredation, whereby a shark consumes an animal caught by fishing gear, can cause higher mortality for target species, injury to sharks and the loss of catch

The catshark genus Scyliorhinus

The catshark genus Scyliorhinus (Chondrichthyes: Carcharhiniformes: Scyliorhinidae): taxonomy, morphology and distribution KARLA D. A. SOARES, MARCELO R. DE CARVALHO ABSTRACT: The catshark genus Scyliorhinus belongs to the family Scyliorhinidae, the most diverse family of sharks, and currently presents 16 valid species according to most modern accounts. The long history of taxonomic rearrangements and inaccurate descriptions

Angling records track the near extirpation of angel shark from two Irish hotspots

Angling records track the near extirpation of angel shark Squatina squatina from two Irish hotspots Samuel Shephard, Ciara Wögerbauer, Peter Green, Jim R. Ellis, William K. Roche ABSTRACT: The angel shark Squatina squatina was historically common in coastal waters fromthe British Isles to north-western Africa, including the Mediterranean. Reported commercial land-ings from northern Europe reduced

Non‐trophic impacts from white sharks complicate population recovery for sea otters

Non‐trophic impacts from white sharks complicate population recovery for sea otters

Non‐trophic impacts from white sharks complicate population recovery for sea otters Jerry H. Moxley, Teri E. Nicholson, Kyle S. Van Houtan, Salvador J. Jorgensen ABSTRACT: Complex interactions between protected populations may challenge the recovery of whole ecosystems. In California, white sharks (Carcharodon carcharias) mistargeting southern sea otters (Enhydra lutris nereis) are an emergent impact to

Predicting the conservation status of Europe’s Data Deficient sharks and rays

Predicting the conservation status of Europe’s Data Deficient sharks and rays

Predicting the conservation status of Europe’s Data Deficient sharks and rays Rachel H.L. Walls, Nicholas K. Dulvy ABSTRACT: Shark and ray biodiversity is threatened primarily by overfishing and the globalisation of trade, and Europe has been one of the most documented heavily fished regions for a relatively long time. Yet, we have little idea of

Velvet belly lanternshark does not use bacterial luminescence

Etmopterus spinax, the velvet belly lanternshark, does not use bacterial luminescence Laurent Duchatelet, Jérôme Delroisse, Patrick Flammang, Jacques Mahillon, Jérôme Mallefet ABSTRACT: Marine organisms are able to produce light using either their own luminous system, called intrinsic bioluminescence, or symbiotic luminous bacteria, called extrinsic bioluminescence. Among bioluminescent vertebrates, Osteichthyes are known to harbor both types

Hybridization between sympatric hammerhead sharks in the western North Atlantic Ocean Amanda M. Barker, Douglas H. Adams, William B. Driggers, Bryan S. Frazier, David S. Portnoy ABSTRACT: Hybridization between closely related species has been documented across a wide range of taxa but has not been well studied in elasmobranchs. Hammerhead sharks have drawn global conservation

Official catch data underrepresent shark and ray taxa caught in Mediterranean and Black Sea fisheries Madeline S. Cashion, Nicolas Bailly, Daniel Pauly ABSTRACT: One in four fishes of the subclass Elasmobranchii (sharks and rays) is estimated to be threatened with extinction, according to the IUCN Red List. Their primary threat is overfishing, but data deficiency
