For the purpose of monitoring the water area of Sevastopol a line of devices for plankton macrofiltration in the size range from 2 mm to 2 microns has been developed. Twelve stations have been chosen from Inkerman to Fiolent with total length of 30 km. From piers far out at sea, 50-500 liters of seawater were sampled from the surface and filtered through a system of successive sieves 2 mm, 300, 150, 84 microns and a 2 μm fiber filter. In the winter of 2021-2022, when the seawater temperature was
