Phytoplankton responds rapidly to nutrient availability variations, becoming a useful indicator for eutrophication and/or management actions reduce it. The present study evaluated the medium-term response of phytoplankton community temperate estuary (Urdaibai estuary) cessation discharges from wastewater treatment-plant (WWTP), comparing physicochemical conditions and before (2020) after (2022) sewerage works. led decrease ammonium phosphate, causing decreases biomass in outer middle increases surroundings WWTP. Community composition also changed, recording an increase prasinoxanthin-containing algae's contribution total biomass, shift inner estuary, mainly flagellates (alloxanthin-containing chlorophyll b-containing algae) diatoms, which could be prompted by change nutrient-ratios nitrogen source, might indicate recuperation system.
