Collapse of Tulka in the Caspian
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).
