Conclusion
247 species among 31 taxa of benthic animals were recorded.
At the moment, only some of the benthos chiefly aquatic insects
could be identified, to family level due to limited literatures.
The important variables controlling the distribution and
abundance of benthic organisms depend upon types of substrate
and sediment stability.
The different characteristics of the sediment usually reflect
circulation patterns of the covering water mass and these
sediment differences are strongly influential in regulating fauna
composition.
The benthic soft-bottom communities are an important one, but
these are very sensitive to environmental impact and should
serve adequately as indicators of change.
