Ma ka honua holoʻokoʻa, ua helu ʻia ka crayfish manamana ākea ma ka IUCN Red List, ma ka hoʻohui ʻelua o ka Berne Convention, ma ke ʻano he ʻano palupalu. Hoʻokomo ʻia kēia maʻi ʻaʻai i loko o nā Red Data Books o Ukraine a me Belarus. Ma nā panalāʻau o ko mākou ʻāina, aia ia i loko o ka Red Book o ka Leningrad Region.
Hiki ke hoʻokaʻawale ʻia nā hana aʻe e like me nā hana pale:
