Collapse of Tulka in the Caspian

Year: 2012 Author: GRID-Arendal
Description:
The comb jelly is well adapted to the habitat (salinity, temperature, and food range) and reproduces faster than endemic species. As it eats the same food as them, it has had a drastic effect on their numbers, upsetting the entire food chain. The commercial fishing industry is afraid of losing the kilka/tulka (g. Clupeonella) and other valuable catches, with consequent effects on human livelihoods and food sources for the Caspian seal and sturgeon population (Huso huso).
