Abstract

Macrohectopus branickii is a unique inhabitant of the Lake Baikal’s pelagial zone that occupies the same ecological niche as Antarctic krill and mysids. However, many aspects of this species ecology are still unknown or disputable. In this study we attempt to clarify the peculiarities of the species distribution in the littoral zone. Since specimens of Macrohectopus branickii are active migrants and participate at daily vertical migrations to the water surface, we used the conus nets designed to catch Macrohectopus branickii during passive floating from the ice surface to the water column. Obtained data revealed the presence of Macrohectopus branickii at a depth over 47 m as well as the fact that migrating schools of the species are not able to enter the specific sites for a long time. We also discussed the capacity of Macrohectopus branickii to freeze into the ice and ecological significance of this specific phenomenon.
