Assessing mariculture water quality with the structural and functional characteristics of a ciliate community
摘要
Abstract
Ciliated protozoa play important roles in micro-ecosystems
especially in marine biotopes. However
few studies have been carried out on the periphytic
or aufwuch
forms in mariculture waters so far. In this study
we sampled periphytic ciliate communities in two closed mariculture ponds (ponds CP1 and CP2) and a natural seawater reservoir (pond RP) using a glass slide method to evaluate their colonizing processes and general ecological features
as well as their application as water quality indicators. We analyzed species compositions
structural parameters (species number
richness
diversity
evenness
abundance and d BP) and functional parameters (G
S eq and T 90%). Pond RP was characterized by higher levels of structural parameters (except for abundance and d BP) and more equal proportion of the major taxonomic groups. The values of S eq were significantly higher in pond RP and similar in both pond CP1 and CP2. It was also demonstrated that environmental factors
including NO2-H
NO3-H
NH3-H
soluble reactive phosphate
temperature and pH
were the first principal factors affecting the communities. Among them
temperature and chemical factors were all significantly and negatively correlated with species number (P<0.01)
richness (P<0.01)
diversity (P<0.01)
and positive correlated with abundance (P<0.01). Opposite correlations between pH and structural parameters were observed. This study showed that there were significant differences in species composition
structural parameters and functional parameters of the periphytic ciliate communities among the ponds
which were in agreement with the water quality. Results of this study confirmed the periphytic ciliate communities to be useful bioindicators of water quality in intensive mariculture waters.
