Biological Communities
The following fish have been found in the Neman: perch, pike, zander, roach, tench, bream, rudd, ruffe, and bleak. Its tributaries also contain stone loach, the three-spined stickleback, minnows, trout, sculpins, gudgeon, dace and chub.
Atlantic salmon formerly migrated upstream to spawn; the dam constructions on the river, most of which took place during the 20th century, reduced their numbers considerably. The dam at Kaunas does not provide fish ladders. The spawning season took place in the fall; ethnographic studies of the time report that night fishing, using torches and harpoons, was a common technique.
