Abstract:
Green tide events have broken out consecutively for years in the Southern Yellow Sea (SYS) of China. Unlike green tides in other countries and regions, those in the SYS show long-range dispersal, with research has primarily focused on the Neopyropia aquaculture area in the Subei Shoal. In this study, the biomass and species composition of attached green algae on the aquaculture ropes for Neopyropia yezoensis were observed across different elevation zones from March to April 2025. The results showed that, without affecting the yield of N. yezoensis, the biomass of attached green algae in the medium-elevation zone (which was exposed to air for about 4 h during the flood season) decreased significantly, and the proportion of Ulva prolifera among the attached green algae also dropped substantially. Specifically, the average biomass of green algae was highest in the low-elevation zone, while values in the medium- and high-elevation zones were relatively lower. This study investigates how different elevation zones (different drying times), affect green algae attached to Neopyropia aquaculture ropes, aiming to provide practical management strategies to mitigate biofouling during cultivation.
