Resumo

The subclass Elasmobranchii, is a group of fish that has raised increasing concerns from a conservation perspective in recent years. The complex biology and reproductive modes of the elasmobranchs contribute to their vulnerability to overfishing. The fisheries that target elasmobranchs have intensified their activities in recent years, impacting their populations on a global scale. In this context, studies in Brazil have led to the inclusion of many elasmobranchs in the list of endangered species, in particular the endemic species in the northern region of the country. The review of the available data aims to analyze the conservation status of the elasmobranch species found in Brazil and the importance of the research techniques that may contribute to the conservation of their stocks.

Abstract

The subclass Elasmobranchii, is a group of fish that has raised increasing concerns from a conservation perspective in recent years. The complex biology and reproductive modes of the elasmobranchs contribute to their vulnerability to overfishing. The fisheries that target elasmobranchs have intensified their activities in recent years, impacting their populations on a global scale. In this context, studies in Brazil have led to the inclusion of many elasmobranchs in the list of endangered species, in particular the endemic species in the northern region of the country. The review of the available data aims to analyze the conservation status of the elasmobranch species found in Brazil and the importance of the research techniques that may contribute to the conservation of their stocks.
