Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries

Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries Jason R.O’Bryhim, E.C.M. Parsons, Stacey L. Lance ABSTRACT: Elasmobranchs represent one of the most imperiled taxa, yet few nations have developed catch limits and no international or bilateral catch limits exist. One barrier to establishing catch limits is a lack of accurate species-specific extraction
