Oscillatoria planctonica Woloszynska,a bloom-forming cyanobacterium,was grown in Fe-deficient and Fe-replete batch cultures using ambient levels of physical factors in natural blooms.

The effects of iron on the growth and physiology of algal bloom of Oscillatoria planctonica , Microcystis aeruginosa and red tide algae of Alexandurium tamarense were studied systemically and comprehensively.

Top-down effects of Anodonta woodiana on nutrient concentration & phytoplankton community composition in a microcosm ecosystem;

Effect of nutrient on periphytic aglae and phytoplankton;

Monitoring and analysis of phytoplankton and the key water quality parameters in the Four Pearl River Openings and the nearby beach waters, PR China;

More than 1 000 samples of algae were identified.

We researched the changes of algae’s and dominant.

Study of the floating algae and water quality of the main line in the diversion of water from Changjiang River to Huaihe River;

Study on floating algae count method for bottled drinking water

Use of inverted microscopic counting method for detecting floating algae in water is characterized by convenience,rapidity,higher accuracy,and less variation coefficient;furthermore,it can give an overall expression to the population density of the sample.

Research progress on technology of microalgae ecological management in shrimp culture;

lemaneiformis on phytoplankton community and two red tidemicroalgae, Heterosigma akashiwo and Prorocentrum micans, were studied in a co-culturingsystem with a series of indoor experiments.

Study on four phytoplanktons carried and spread WSSV;

utilization on a micro-ecological environment in shrimp pond was studied primarily by detecting the changes of phytoplankton,heterotrophic bacteria and Vibrio in the pond water and sediment.

This paper reports the results of influences of bacillus on phytoplankton in intensive shrimp ponds, analyzes the weekly variation of species composition, biomass and dominant species of phytoplankton on period of culture.
