Osmoregulation by the gastro-intestinal tract of marine fish at depth – implications for the global carbon cycle Summary: Blackbelly rosefish at greater depths contribute to global carbonate production according to predictions from size and temperature. Pressure and temperature have little effect on ichthyocarbo...

A new study from researchers at @miamirosenstiel.bsky.social found #mesopelagic fish release carbon to their surroundings @ similar rate to surface fish. This study examined intestinal carbon in #blackbellyrosefish at capt ure or maintained in captivity
