In the spawning area we meet spawners as well as their ”satellites”
Members of the LK forum have been interested in what small animals we can see in action in such waters. The information below is provided by Henn Timm from the Estonian University of Life Sciences:
"In the upper reaches of rivers and streams where the flow is rapid and the water is cold there is almost no plankton. The zoobenthos (the animal fauna of the bottom) is dominated by crenobiotic species (invertebrate aquatic organisms living in cold spring waters), for instance unicellular species, crustaceans, insect larvae, leeches, snails … Typical fish species are river trouts and graylings “.
