Abstract
The health condition of eel, Anguilla anguilla (L.), caught in the Szczecin Lagoon off Trzebież in 1971-1913 and in 6 fishing grounds in 1982-1983 is evaluated. The clinical analysis, anatomo-pathological examinations, and hematologic parameters demonstrated a considerable increase in the incidence of circulatory disorders involving acute or chronic damaging inflammations, dominated by necropoietic lesions in viscera. The extent of pathologic changes is conditioned by, i.a., toxic effects of cyanobacteria (including Microcystis aeruginosa) blooms occurring in the Lagoon′s eutrophic waters.
