A recent study by researchers in the UK, US, and Canada found that fifteen percent of marine calcium carbonate is in fact excreted by fish I never knew this but it is a good thing to know. Teams believe that it could be varying as much as three times higher. The article all so said fish are therefore responsible for contributing a major but previously unrecognized portion of the inorganic carbon that maintains the oceans acidity. The co2 will cause fish to produce even more calcium carbonate that is really cool how it can do that. This calcium carbonate is white, chalky, material that reduces the acidity of the sea water so the fish are producing this for the environment to keep it functioning right.
The ocean acidity has a large effect on marine ecosystems, including coral reefs, and controls how easily the ocean can absorb increases in the atmospheric co2. One thing that interested me the most is how calcium carbonate is produced and it is produce by bony fish, a group including 90 percent of marine fish, but not sharks or rays, which have cartilaginous skeletons. Calcium carbonate is crystals are in the gut and excreted out. Now I have no clue how the fish produces this but is vary interesting. Three to 15 percent of the ocean carbonate comes from fish, but this range could be up to three times higher this is a lot that they are producing.
Predicting that the combination of increases in sea temperatures and rising co2 expected over this century will cause fish to produce even more calcium carbonate I think that this is cool but I really wish the article would of told more about really how they produce it. Increasing co2 in their blood directly stimulates carbonate production by the gut specifically I was wondering why this does happen in the gut and not somewhere else but they didn’t answer this question but they did answer one that calcium carbonate is good for fish in the ocean and they are producing it at a constant rate.
