Net pens/ Cages
There are large impacts of the direct environment of aquaculture in cages and open net pens, without proper measures and enforcement thereof. These impacts include escapes, irresponsible use of drugs and chemicals and eutrophication of the surrounding water with waste from the aquaculture. There is also risk of the spread of diseases and parasites to the wild population of the critically endangered beluga sturgeon.
There are good regulations to protect the ecosystem and the wild populations of sturgeon against the negative impacts of aquaculture in the Black Sea. Multiple incidents show that the enforcement of these regulations is not sufficient.
