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.
This is how we get #BetterData

Following the publication of the paper “Thailand’s missing marine fisheries catch (1950-2014),” the Sea Around Us received an email from Thailand’s Department of European Affairs. We welcome such communications and engagements with countries.
The electronic communication included a series of media statements that highlight a range of initiatives undertaken by the Prayut Chan-o-cha government to promote best practices in the fisheries sector.
The Sea Around Us – Indian Ocean under the lead of Professor Dirk Zeller is looking for outstanding international PhD candidates interested in conducting ‘big-data’ research on fisheries and fisheries conservation issues at the ocean-basin scale. If this is of interest to you, then consider applying for an international PhD Scholarship at the University of Western Australia in Perth. The current round of applications closes on April 6, 2018 and is for international candidates only.
Is there a connection between countries’ human development, fisheries data and the way ocean resources are managed? There is one (or many), indeed.
