The amount of fish being caught worldwide is much larger than has been reported. And that could mean serious problems for the environment and nations that depend on fisheries. A new estimate places the world fish catch at 109 metric tons. That is 32 million tons higher than the yearly totals governments have been reporting. The same report notes that the world’s fish catch has been shrinking since the late 1990s. Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing. This includes that fishing done for recreational and individual food and the catches of small commercial fisheries, known as artisanal fisheries. Daniel Pauly of the University of British Columbia led the study. He noted that a large percentage of the world’s fish catch is thrown away. He told VOA that better estimates of the actual global catch will help ensure there will be enough fish in the future. He added that fish catches have been decreasing since 1996. The researchers also found ways that the world’s fisheries are changing. It found that fishing fleets of larger nations are catching fish in the waters of developing countries more and more. Daniel Pauly said he was surprised by the amount of fishing done by foreigners in competition with local fishers. He said many European and Asian fishing boats are operating in waters off the coast of West Africa, for example. The online journal Nature Communications published the findings.
