Fish biomass in the ocean may be 10 times higher than estimated: Stock of mesopelagic fish changes from 1,000 to 10,000 million tons

With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean. However, scientists have found that their abundance could be at least 10 times higher. The results are based on the acoustic observations conducted during the circumnavigation of the Malaspina Expedition.
