To investigate the impact of freshwater discharge variations from Nanliu River on phytoplankton community structure in Lianzhou Bay, we conducted surveys total chlorophyll- a (Tchl- ) concentrations and specific pigment groups during wet dry seasons 2016. During season, introduced substantial freshwater, nutrients, suspended particulate matter into Bay. Due to reduced light availability, Tchl- at most stations were lower compared season. The result indicated that availability often exerts greater influence than nutrient estuarine environments. Furthermore, spatial distribution Bay is correlated with feeding activities bivalve aquaculture water movement within bay. high-water period, was primarily composed diatoms (35.0%), cyanobacteria (21.0%), prasinophytes (13.0%), chlorophytes (19.0%), cryptophytes (11.0%). In contrast, low-water period saw dominated by (62.0%), (18.0%), (12.0%), (7.0%). absence osmotic regulation restricts their environments characterized high availability. exhibit affinity for well-illuminated conditions, thereby contributing significantly primary productivity neritic zones periods low flow.
