Using harmonized historical catch data to infer the expansion of global tuna fisheries

Despite worldwide demand for tuna products and considerable conservation interest by civil society, no single global dataset exists capturing the spatial extent of all catches from fisheries for large pelagic species across all ocean basins. Efforts to spatially quantify the historical catch of global tuna fisheries have been restricted to the few taxa of major economic interest, creating a truncated view of the true extent of the fisheries for tuna and other large pelagic fishes.

High-seas fish biodiversity is slipping through the governance net

States at the United Nations have begun negotiating a new treaty to strengthen the legal regime for marine biodiversity in areas beyond national jurisdiction. Failure to ensure the full scope of fish biodiversity is covered could result in thousands of species continuing to slip through the cracks of a fragmented global ocean governance framework.

A low-cost satellite revolution is paving the way for real-time monitoring of fishing vessels using synthetic-aperture radar (SAR). SAR allows researchers to monitor ‘dark vessels’ that aren’t transmitting Automatic Identification Signals (AIS) location data.
