Effects of seaweed Gracilaria verrucosa on the growth of microalgae: A case study in the laboratory and in an enclosed sea of Hangzhou Bay, China
Effects of Gracilaria verrucosa through competition for nutrients on microalgae were evaluated in the laboratory and in an enclosed sea with an area of 1.72km2 in the northern part of the East China Sea. Results showed that the concentration of NH4-N, NO3-N and NO2-N in the monoculture of G. verruco...

Results showed that the concentration of NH4-N, NO3-N and NO2-N in the monoculture of G. verrucosa was significantly correlated with that in co-culture of G. verrucosa with Karenia mikimotoi (p<0.01) during the period of experiments, but the concentration of dissolved inorganic nitrogen (DIN) in the monoculture of K. mikimotoi changed little, which indicated that the DIN was mainly absorbed by G. verrucosa in coexistence systems, while the PO4-P in the coexistence assays was absorbed jointly by G. verrucosa and K. mikimotoi. Corresponding to the dramatically decline of the DIN concentration, the K. mikimotoi density was significantly decreased, which indicated that the growth of K. mikimotoi was suppressed by G. verrucosa mainly through competing for nutrients, especially for nitrogen. In the eutrophic seawater with G. verrucosa cultivation, the nutrient concentration was dramatically decreased compared with the control, and synchronously, the phytoplankton population density was also significantly lower compared with the control. Furthermore, the species diversity, richness and evenness were significantly increased during the period of G. verrucosa cultivation, and non-HAB species dominated the phytoplankton population. The results of present paper indicated that G. verrucosa cultivated in the real field would probably suppress the survival and growth of phytoplankton by competing for nutrients, especially for nitrogen.</description><identifier>ISSN: 1568-9883</identifier><identifier>EISSN: 1878-1470</identifier><identifier>DOI: 10.1016/j.hal.2011.02.003</identifier><language>eng</language><publisher>Kidlington: Elsevier B.V</publisher><subject>Algae ; Animal and plant ecology ; Animal, plant and microbial ecology ; Autoecology ; Biological and medical sciences ; case studies ; dissolved inorganic nitrogen ; Fundamental and applied biological sciences.
