A ban on crayfish catching has been imposed in most Ukrainian water bodies from August 5 to September 20, to safeguard the crayfish population during their vulnerable molting period. The ban, which can result in administrative or criminal penalties along with a fine of UAH 3,332 per crayfish, is necessary as crayfish, being expensive aquaculture products, undergo a necessary molting process where they shed their strong shell and other protective layers, making them more exposed and vulnerable. The ban in certain regions starts as early as August 10.
