Abstract

Abstract

In this study, we conducted comprehensive field surveys in the Bohai Sea’s seagrass beds at Caofeidian, Yellow River mouth, and Juehua Island, gathering data on seagrass growth, water and sediment quality, plankton, benthic life, and juvenile fish. An integrated assessment index system for the nursery function of nearshore seagrass beds was constructed. The seagrass biomass at Caofeidian and Juehua Island was measured at 371.22 g m⁻² and 340.05 g m⁻², respectively, both of which were significantly higher than that recorded at the Yellow River mouth (161.24 g m⁻², p < 0.05). The average abundance and biomass of phytoplankton in each seagrass bed followed the order: Yellow River mouth > Caofeidian > Juehua Island, exhibiting significant spatial differences (p < 0.05). Regarding juvenile fish density, Juehua Island exhibited the highest density, followed by the Yellow River mouth, with Caofeidian showing the lowest density, also demonstrating significant spatial differences (p < 0.05). The nursery function of seagrass beds was best in Juehua Island seagrass bed, followed by Caofeidian seagrass bed and Yellow River mouth seagrass bed. Environmental and biological indicators with significant contributions varied spatially. The seagrass bed in Juehua Island has a good environmental and biological status, with high water transparency, abundant dissolved oxygen, and moderate inorganic nitrogen concentration, and the juvenile fish community indicators all performed well, contributing significantly to the nursery function. The seagrass bed in Yellow River Delta has relatively poor water environment and biological status, with low water transparency, high pH value, and excessive inorganic nitrogen. The biological indicators showed poor plankton diversity characteristics and low proportion of juvenile fish, which became the main negative factors for its nursery function assessment result of only average. The environmental status in Caofeidian seagrass bed is good, with factors such as temperature, inorganic nitrogen, and inorganic phosphorus concentration contributing significantly. However, its biological status is average, and the low number of planktonic animals and juvenile fish is the main negative factor in the nursery function assessment of this area. This study helps to deeply understand and recognize the spatial and temporal differences and driving factors of the nursery function of typical seagrass beds in the Bohai Sea area, and provides effective scientific basis and data support for the protection of seagrass bed ecosystems and the sustainable development of marine fishery resources in China.
