Cambaroides schrenckii has been assessed as Data Deficient. There are a number of potential threats affecting this species such as water pollution and crayfish plague. However little is known on the distribution of this species or the impact these threats are having on the population. Further research is needed on the impact of these threats on population numbers, along with further studies to determine true range before a more accurate assessment of conservation status can be made.

There is no population information available for this species. However, it has been suggested that the density of juveniles is less than 50 per m2 and adults are 3-7 individuals per m2 (T. Kawai pers. comm. 2008).

This species seems to be restricted to lentic water in flats and open rivers, lakes, or dead channels, to a depth of approximately 1 m. It is also known to occur in brackish water such as coastal areas of the Amurskii Liman (Y. Machino pers. comm. 2009). On Sakhalin Island, its optimal water temperature is around 19ºC and pH is 6.5-7.0 (Labai 2005). It inhabits mesotrophic or oligotrophic conditions, silt or sand substrate, usually covered by detritus and vegetation snags (T. Kawai pers. comm. 2008). Floating plants may also occur on the surface of the habitat, and emergent plants or sub-emergent plants dominate in shallow areas (T. Kawai pers. comm. 2008). Gammarid amphipods and snails are known to cohabit with this species. Adult females and males mate during October, females are ovigerous laying 200-240 eggs in spring (T. Kawai pers. comm. 2008).
