Abstract Coastal ecosystems, such as lakes and lagoons, are unique valuable water bodies whose proper functioning depends on hydrological connectivity with the sea or ocean. Human interventions, construction of storm surge barriers, that block periodic free influx seawater into induce a permanent freshwater state. This study presents disturbances, considered environmental stressors, initiating changes in assemblages Chironomidae larvae inhabiting bottom Lake Jamno (southern coast Baltic Sea). Changes structure this were assessed during long-term (2010–20), which two periods: time intrusion (FF) seven years blocked (BF). The findings indicate that, following activation α-diversity consistently decreased throughout lake. Concurrently, density by over 20%, although their biomass increased. In last year gates, diversity studied insects was drastically reduced limited to only genus: Chironomus sp. Procladius sp., serve indicators disturbances aquatic ecosystems undergoing line deterministic chaos theory. information provided indicates increases salinity significantly affect larvae, though it should be component several other parameters (EC, temperature, nutrients).
