Abstract
Understanding trade in marine resources is challenging given the high uncertainty surrounding total catches, domestic consumption, imports, and exports. This challenge is further confounded for sharks and rays that present very different markets for fin versus non-fin commodities – including meat, oil, and cartilage. While the global trade in shark fins is relatively well understood, trade in shark meat presents a potentially increasing threat to populations, driven in part by increasing demand and potential emergence of new markets as the result of “fins attached” policies. Here we decompose global trade in shark and ray meat products using a unique statistical modelling approach and expert opinion, revealing both broad trends in demand as well as the identities of the species involved. This work establishes a new baseline for monitoring trade in shark meat and understanding the role of regulatory change in addressing demand for shark and ray products.
