How much fish are we really catching?
January 19, 2016 By Rebecca Goldburg The Pew Charitable Trusts ‘Thirty percent of global fish catch may be unreported, according to new research. Activities such as artisanal, subsistence, and illegal fishing are often not included in official statistics—obscuring the true extent of fishing worldwide. Scientists now estimate global catch is 109 million metric tons (mt) annually. In a new study, scientists led by Sea Around Us calculated the annual global fish catch to be roughly 109 million metric tons, about 32 million metric tons more than officially reported in 2010 by more than 200 countries and territories.
The new estimates provide countries with better assessments of their catch levels than they have had before. Joshua Reichert, executive vice president and head of environment initiatives for The Pew Charitable Trusts, calls the research a “groundbreaking study that confirms that we have been taking far more fish from our oceans than the official data suggest and provides a nuanced portrait of the amount of fish that are being removed from the world’s oceans each year.”
In the study, published Jan. 19 in the journal Nature Communications, lead author Daniel Pauly and co-author Dirk Zeller gathered information with help from hundreds of scientists around the world. This team of researchers examined fish catch data for more than 200 countries and territories from a broad range of sources, including academic literature, industrial statistics, local fisheries experts, law enforcement, human population data, and other records such as documentation of fish catch by tourists. Using a method called “catch reconstruction,” the Sea Around Us team then estimated total catch, including that missing from official data. Too see more go to the Pew website.
