[1] Epischurella baikalensis inhabits the entire water column, and produces two generations per year: the winter–spring and the summer.

These copepods develop under different ecological conditions and vary in the duration of life stages, reproduction time, maturation of sex products and adult males and females lifespan.

One of the most essential features of the ecology of E. baikalensis is the alteration of its mass inhabited areas during a year, as well as in day time.

This is due to the need for various conditions for gonad maturation, reproduction, nourishing and protection from being consumed by planktivores.

[2] The IUCN Red List has adopted this naming scheme,[1] while other databases such as the World Register of Marine Species still use the Epischura combination.
