Daniel Pauly talks climate change and fisheries in Peru

The Sea Around Us Principal Investigator, Daniel Pauly, is in Peru attending a series of meetings this week and is scheduled to offer a couple of public talks to discuss his most recent research on climate change and global marine fisheries.

The first event will take place on Thursday, April 19th at the Universidad Nacional Agraria La Molina, where he will talk about the impact of fisheries and global warming on marine ecosystems.

Bottom trawling is causing “boom and bust” fisheries.

A new study using the Sea Around Us’ reconstructed catch data reveals that in the past 60+ years, the practice of towing giant fishing nets along the sea floor has caused the extraction of 25 million tonnes of fish that live 400 metres or more below sea level leading to the collapse of many of those fish populations.

Catch reconstructions are not always easy to explain to non-scientists.

How did the Sea Around Us find out that overfishing has caused a steady decline in catches since the mid-1990s? What sources did researchers use? What’s the difference between officially reported figures and the Sea Around Us’ numbers?

More accurate data substantially improves fisheries monitoring and, in return, better monitoring generates better data. The overall result would be a greater protection to global fish stocks.
