According to scientists, fishes are the dominant vertebrates in the ocean and they contribute roughly 16% of the sinking carbon in feces and other matter, scientists have little knowledge of the role fishes play in the global carbon cycle associated with climate change.
A study led by Rutgers found out that carbon in feces, respirations, and other excretions from fishes make up about 16% of the total carbon, which is roughly 1.6 billion tons that sink below the ocean s water upper layers annually.

Earth s Biological Pump
According to study, more data on this important part of the Earth s biological pump will assist researchers to understand the impact of climate change and harvesting of seafood on the role of fishes in carbon flux. In the journal Oceanography and Limnology, which recently came into existence, carbon flux is the amount of carbon exchanged in the ocean, containing from the surface to the deep sea, which is the focus of this study.
