Analysis of community structure of planktonic algae and periphyton algae in aquarium landscape tanks
In order to investigate the changes in the community structure of planktonic algae and periphyton algae in aquarium landscape tanks,this experiment collected sampling and analysis of the two algae categories in three aquarium landscape tanks.The results showed that there were a total of 7 phyla and 50 species of planktonic algae in the aquarium landscape tanks,with the dominant species mainly being Cyclotella meneghiniana from the diatom phylum.Tank 1 had diatoms as dominant in the early stage of the experiment,while green algae became dominant in the later stage.The other two tanks maintained a high proportion of planktonic diatoms throughout the experiment.There were a total of 5 phyla and 24 species of dominant periphyton algae in the aquarium landscape tanks,with Navicula sp.from the diatom phylum being the main dominant species.Planktonic algae and periphy-ton algae in the aquarium tanks reached a high density 15-20 days after the completion of landscaping and water filling,posing a risk of algal bloom,with periphyton algae having a higher risk than planktonic algae.Methods such as water changes,controlling light intensity,and stocking appropriate amounts of Neocaridina spp.are effec-tive in controlling algal blooms.
