30 PER CENT OF GLOBAL FISH CATCH IS UNREPORTED
Countries drastically underreport the number of fish caught worldwide, and the numbers obscure a significant decline in the total catch .
The new estimate, released today in Nature Communications, puts the annual global catch at roughly 109 million metric tons, about 30 per cent higher than the 77 million officially reported in 2010 by more than 200 countries and territories. This means that 32 million metric tons of fish goes unreported every year, more than the weight of the entire population of the United States.
Researchers led by the Sea Around Us, a research initiative at the University of British Columbia supported by The Pew Charitable Trusts, and Vulcan Inc., attribute the discrepancy to the fact that most countries focus their data collection efforts on industrial fishing and largely exclude difficult-to-track categories such as artisanal, subsistence, and illegal fishing, as well as discarded fish.
“The world is withdrawing from a joint bank account of fish without knowing what has been withdrawn or the remaining balance,” said UBC professor Daniel Pauly, a lead author of the study and principal investigator of the Sea Around Us. “Better estimating the amount we’re taking out can help ensure there is enough fish to sustain us in the future.”
