Transport of nitrite across fish gills

J Exp Zool. 1980 Oct;214(1):119-21. doi: 10.1002/jez.1402140115.


The results show that rainbow trout (Salmo gairdneri) are able to concentrate NO2- ions in the blood plasma. After 24 hr in water containing 0.7 mM/l NO2-, the blood plasma contained about 5 mM/l NO2- suggesting that the gills have the ability to transport NO2 against a concentration gradient.
