Using intracellular pH (pHi) imaging, we investigated Cl transport mechanisms in freshwater rainbow trout gill mitochondrion-rich (MR) cells. In isolated MR cells, scanning electron microscopy has shown that cellular polarity is maintained.

<h3></h3><h3>What is Transport in Two Species of Freshwater Fish?</h3>

Large amounts of diluted water constantly flow across the gill epithelium of freshwater fish, causing them to experience an ionic stress. Since the mechanisms of ion and acid-base transport are connected at the gill, this is made worse by an acid-base disruption. Active transport at specialised mitochondrion-rich (MR) cells on the gill surface helps the fish maintain homeostasis. As a result, the freshwater gill has served as a crucial model system for figuring out the transport processes that allow for the overriding of adverse ion gradients. Numerous research have tried to clarify the mechanisms of ion and acid-base transport in freshwater fishes during the past ten years using a range of methodologies.
