Wonderful underwater nature
A school of common roach and European perch was recently observed inhabiting the waters of Lake Niesłysz, located near the village of Niesulice. The fish were seen swimming gracefully through the very dense underwater plants that thrive along the lakebed. This detailed footage was captured using the advanced SB-1 submarine, equipped with high-resolution imaging technology. The mission allowed scientists to monitor aquatic behavior without causing surface disturbance. The visibility revealed the vibrant ecosystem hidden beneath the waves, providing valuable data on local fish populations and their interaction with submerged vegetation during the seasonal migration period in this protected region.
