Deep-sea fish confirmed as a significant source of ocean carbonate
Miami FL (SPX) Jul 25, 2025
A new study offers the first direct evidence that deep-dwelling mesopelagic fish, which account for up to 94 percent of global fish biomass, excrete carbonate minerals at rates comparable to shallow-water species. The findings validate previous global models suggesting that marine fish are major contributors to biogenic carbonate production in the ocean. Scientists at the University of Mia
