Re: mineral uptake

[Mike & Diane Wise <apistowise@fgn.net>]

Keny,

Freshwater fish don't drink water & even squeeze as much moisture out of their food as they can before swallowing. Another tactic to reduce intake of water. Obviously some gets through, but very little. That's why the have super efficient kidneys. Actually most absorption of outside chemicals (medicines & minerals) is through the gills.

When a fish eats a certain amount of water is going to be ingested <duh> so if the water is rich in minerals each and everytime a fish eats its going to be getting extra minerals.  I dont know about the extraction of air though the gills if maybe the water passing though there might present absorbtion options, I do admit a lack of knowledge here.
