Fisher perceptions of catch and trade of sharks and rays in Angolan small‐scale fisheries

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 5, May 2024.
Abstract Small‐scale fisheries ensure food security and employment in Angolan coastal communities. These dynamic, widespread fisheries remain mostly unregulated, with limited data available despite their likely significant impact on marine megafauna. We used an interview‐based survey to investigate local fisher interactions with elasmobranchs (sharks ...

Venom gland transcriptome analyses of two freshwater stingrays (Myliobatiformes: Potamotrygonidae) from Brazil

open access: yesScientific Reports, 2016
AbstractStingrays commonly cause human envenoming related accidents in populations of the sea, near rivers and lakes. Transcriptomic profiles have been used to elucidate components of animal venom, since they are capable of providing molecular information on the biology of the animal and could have biomedical applications.
