Feeding investigations of silver carp (Hypophthalmichthys molitrix) fingerlings with emphasis on dominant phytoplanktons2- Determining the effects of microalgae Diatoma and Chlorella on growth parameters and survival rate of silver carp juvenile (Hypophthalmichthys molitrix)3- Identification, purification and preparation of microalgae collectiBased on carried out studies on the first and the end party of their intestine and the pond water, phytophague fingerlings feeds on phytoplankton, zooplankton and detritus. But the essential nutrition was on phytoplankton and detritus. Planktonic groups were formed of Cyanophyta, Chlorophyta, Bacillariophyta and Euglenophyta. But in addition to these four groups Pyrophyta was present in fish pond water. Relative abundance of these nutrient organisms in water and intestine was different. Also in most cases a direct relation was observed between the intensity of water organisms and intestine ingredients. Based on this study, essential differences of digestion were observed following to the source of nutrition and the most difference were considered in digestion of Bacillariophyta, Cyanophyta and Chlorophyta.
