Abstract: The species composition and biomass of phytoplankton were monthly monitored in a sea cucumber Apostichopus japonicus culture pond of 600 m in length×80 m in width×1.2-2.0 m in depth in coastal Dalian 3-5 days before high tide from October of 2015 to September of 2016 under three water quality regulation methods including a 750 W water quality regulator, a micropore aeration system, and natural pond without any aeration system. It was found that there were the same trends of species composition and annual biomass of the same phylum in the phytoplankton in the three ponds with different water quality regulation methods, even though 7 phyla of phytoplankton including Bacillariophyta, Pyrrophyta, Chlorophyta, Cyanophyta, Euglenophyta, Chrysophyta, and Cryptophyta), and 79 species were observed in all ponds. The annual average biomass of phytoplankton was(16.67±0.19) mg/L in the natural pond without any aeration system,(17.44±0.16) mg/L in the pond with a micropore aeration system, and(20.10±0.13) mg/L in the pond with a 750 W water quality regulator, significantly higher than that in the natural pond without any aeration system. The maximal biomass of phytoplankton was Bacillariophyta, followed by Euglenophyta and Pyrrhophyta in the three regulation pattern ponds. There were higher biomasses of Bacillariophyta, Euglenophyta, Chlorophyta and Cryptophyta in the pond with a 750 W water quality regulator than that in the natural pond without any aeration system in which the biomasses of Cyanophyta and Chrysophyta were higher than those in the pond with a micropore aeration system, and in the pond with a 750 W water quality regulator. Statistical analysis revealed that the main factors influencing phytoplankton biomass were temperature, salinity,and levels of active phosphate and nitrite. The findings showed that water quality in the pond with a 750 W water quality regulator was better for phytoplankton growth.
