Since mid-1970s, benthic communities in the Puck Lagoon have been subject to considerable adverse changes. Firstly, a marked reduction of underwater meadows and phytal invertebrate communities appeared, accompanied by changes in fish fauna. Biomass of the macrozoobenthos increased as a result of increasing inflow of allochthonous organic matter and progressing siltation of the bottom. The bivalve biomass increased, while that of the Crustacea, Gastropoda, larval Insecta, and Nemertini decreased.
