The construction and running stability of the ecological system in seawater aquarium

Abstract:

In order to provided building sites of biological collocation and landscape effect for plankton, large algae, fish and others' optimal growth model, we analysed the building model of aquatic animals in filtration and temperature control system through the establishment of aquarium.According to the aquarium market research, the animal and plant configuration in system is as follows.The clean shrimps and coral is 5:1, Rhodophyta, Chlorophyta and Phaeophyta is 7:5:3.The water quality monitoring result showed that the water hardness, TN and TP were maintains at 5 159 mg/L, 28.38 μmol/L and 6.09 μmol/L during stable phase respectively .The water quality was reached to the second class of the water standard, which is suitable for mariculture.It is the construction of the evaluation index system of ecological system stability that to evaluate the system's running efficacy.While the result shows that R=8.54, the system is between intermediate and high stability, and biodiversity in the ecological system is the determinant factor.A stable mariculture system is time-saving and cost-saving，providing places for animal and plant breeding research and achiveing the multiple effects, such as being scientific, economic, stable, beautiful, etc.The construction of the system model also provides theoretical basis for the "economy-ecological-humanities" life philosophy.
