Nitrogenous waste excretion and accumulation of urea and ammonia inChalcalburnus tarichi (Cyprinidae), endemic to the extremely alkaline Lake Van (Eastern Turkey)
@article{Danulat2005NitrogenousWE, title={Nitrogenous waste excretion and accumulation of urea and ammonia inChalcalburnus tarichi (Cyprinidae), endemic to the extremely alkaline Lake Van (Eastern Turkey)}, author={Eva Danulat and Stephan Kempe}, journal={Fish Physiology and Biochemistry}, year={2005}, volume={9}, pages={377-386} }
The endemic, anadromous cyprinidChalcalburnus tarichi is the only fish species known to occur in alkaline Lake Van (Eastern Anatolia, Turkey). EightC. tarichi were maintained individually in Lake Van water (17 – 19°C; pH 9.8; 153 mEq·I−1 total alkalinity; 22‰ total salinity) and tank water samples analyzed for 24 h in 2 to 4 h intervals. At zero time, < 1µM ammonia was present and urea was undetectable in the tank water; at 24 h, total ammonia and urea made up 114±32 and 35±25µM, respectively…

Przewalski’s Naked Carp (Gymnocypris przewalskii): An Endangered Species Taking a Metabolic Holiday in Lake Qinghai, China
- Environmental SciencePhysiological and Biochemical Zoology
- 2006
The naked carp is an endangered cyprinid that migrates annually between freshwater rivers and Lake Qinghai, and appears to be benefiting from a metabolic holiday at present because of decreases in iono‐ and osmoregulatory costs while in lake water; elevated plasma [Mg2+]; ammonia may be additional factors depressing metabolic rate.
