A research was accomplished to examine the extraction and characterization of chitosan (polymer) from four different organism of fresh water i.e. fish scales, bivalve, prawn and crab shells. Extracted chitosan has been produced by using various parameters i.e. demineralization Deproteinization and DE acetylation as chemical methods. Results showed that chitosan was found at maximum in the crab (Bareytelphusa guerini) 87.29% followed by Prawn (Macrobrachium rosenbergii) and scales of fish (Channa striatus) which have an average yield (38.55% and 32.56%) respectively and (18.14%) which is lowest yield among all obtained from fresh water mussel (bivalve). The chitosan extracted from the samples were characterized by Fourier transform infrared spectroscopy (FTIR) and existence of chitosan was confirmed.
