Food scarcity is a global problem and is increasing day by day due to population explosion, rapid industrialization, increasing demand of natural resources and pollution. The scientists are trying to solve this problem by increasing agriculture productivity as well as harvesting animal resources. Now, this is also reached to a level of saturation so new tools and technology are needed to be explored to solve food problem. In the present paper, SCP production from different sources using many microorganisms specially oil seeds cakes and Soya waste, as a substrate for single cell culture and protein production in laboratory and as a pilot project has been discussed in the present paper.

Zooplanktons are microscopic free floating animals which play a vital role in aquatic ecosystem zooplanktons are highly sensitive to environment variation, as a result change in abudance species diversity or community composition can provide important indication of environmental health.in the present paper an extensive review of the literature available on zooplanktons in lotic water of India have been made which is a long felt necessity in this field.
