..., has an established role in potassium and acidbase regulation in mammals and is well known for its role in gastric acidification. However, the role of HKA in extra-gastric organs such as the gill and kidney is less clear, especially in fishes. In the present study in Nile tilapia, Oreochromis...

... regulation among fish by measuring pH i regulation in 10 different fish species that are broadly phylogenetically separated, spanning six orders, eight families and 10 genera. Contrary to previous views, we show that preferential pH i regulation is the most common strategy for acidbase regulation within...

... regulation has been identified in several adult fish species and an aquatic amphibian, but never in adult amniotes. Recently, common snapping turtles were observed to preferentially regulate pH i during development; the pattern of acidbase regulation in these species shifts from preferential pH i regulation...

... in marine invertebrates. Our pH e measurements suggest that A. filiformis is a weak acidbase regulator, similar to other echinoderms, which cannot fully compensate for an extracellular acidosis during environmental hypercapnia. However, in accordance to other echinoderms (see Stumpp et al., 2012...

...K. M. Gilmour; S. F. Perry SUMMARY Carbonic anhydrase (CA) is the zinc metalloenzyme that catalyses the reversible reactions of CO 2 with water. CA plays a crucial role in systemic acidbase regulation in fish by providing acid–base equivalents for exchange with the environment. Unlike air...
