Abstract
Fish scale wastes are generally discarded in the environment through fish processing industries and local market vendors. It is one of the excellent and efficient renewable bioproducts. Consequently, a number of bioactive compounds have been identified including bioactive peptides, collagen, chitosan, and gelatin which are commercially marketed. The current study involves the extraction and generation of chitosan nanoparticles from fish scales. The synthesized chitosan nanosubstances were categorized by Field Emission Scanning Electron Microscopy (FESEM). The viability of utilizing fish scales as an economical bio-adsorbent for elimination of textile dye was studied on industrial effluent. Fourier transform infrared spectroscopy (FTIR) was used to study the dye adsorption of chitosan nanoparticles before and after the dye treatment. With chitosan nanoparticle treatment of the textile effluents, removal of COD was improved to 80% and the turbidity removal efficiency was improved up to 90%. Thus, the present study provides an excellent bio-adsorbent chitosan nanoparticle generated from fish scales which have potential application as an adsorbent in bioremediation like wastewater treatment.

Summary
Functional bioactive ingredients are known to attract the scientific community, consumers and food manufacturers and there is a steady growth in the scientific evidence supporting the concept of health-promoting ingredients [1] [2]. Natural polysaccharide is a partially deacetylated polymer of N-acetyl glucosamine obtained through alkaline deacetylation of chitin [3] [4] [5] [6]. Apart from this, chitosan is known to have medical, therapeutic, pharmaceutical and biomedical properties and used in agricultural sector as well [9]-[15]. The attribution of chitosan to the textiles industry is considered multi-functional, both chemically and microbiologically [16]-[22]. Large amounts of scale wastes were discarded post consumption of these species and harmed the environment. Chitin and chitosan can be extracted from the discarded fish scales and protect the environment. This study deals with the preparation of chitosan nanostructures from fish scale wastes and their application as a bio-adsorbent in wastewater treatment from textile industrial effluents
