The challenge of implementing environmental DNA metabarcoding to detect elasmobranchs in a resource‐limited marine protected area

Abstract

Elasmobranchs are threatened and eDNA metabarcoding is a powerful tool that can help efforts to better understand and conserve them. Nevertheless, the inter‐calibration between optimal methodological practices and its implementation in resource‐limited situations is still an issue. Based on promising results from recent studies, the authors applied a cost‐effective protocol with parameters that could be easily replicated by any conservationist. Nonetheless, the results with fewer elasmobranchs detected than expected reveal that endorsed primers and sampling strategies still require further optimization, especially for applications in resource‐limited conservation programmes.
