Abstract

In the last decades chondrichthyans populations have sorely declined mainly because of overexploitation due to unregulated fishing. As a result, at the present day, a quarter of the extant chondrichthyans species is considered threaten with extinction. The shark fin trade is a very diverse phenomenon and it targets the whole chondrichthyans class. Once the processed products are on the market, it is not possible to trace them back to the individual of origin, due to the absence of a relationship between catch data and traded products. This aspect makes the impact of shark fin trade on chondrichthyans populations difficult to address. Therefore, the need to develop a tool able to identify the origin of the products seems necessary. Molecular techniques can detect the species of origin accurately, utilising just a small fragment of tissue from products presenting different grade of processing. This essay intends to illustrate the overall framework of the trade in chondrichthyans products, most commonly known as shark fin trade as well as present examples of molecular approaches developed to detect species, in order to help to find new insights and guidelines for chondrichthyans conservation.
