Abstract

The present study was undertaken to investigate the suitability for the transformation of fish market waste into silage by using two different solvents; Inorganic (98% sulphuric acid) organic (98% formic acid). Indian aquaculture, which is dominated by carps, is extremely promising and has increased by more than six and a half times in the last two decades, with freshwater aquaculture accounting for more than 95% of total aquaculture production. Only 25-50% of the raw material is used for human consumption, according to estimates. The remaining 50-75% of raw material is processing waste and can be used to make low-valued goods. Fish silage was prepared using 3.5% sulphuric acid and formic acid with added Butylated Hydroxy Tolune (BHT). The storage is always a problem in silage production. The study was conducted for 60days at room temperature. The biochemical parameters (pH, TVB-N, TBARS, AAN) gradually increase during the course of storage but does not exceed the acceptable level.

Conclusion

Freshwater fish processing generates a large amount of processing waste, the most common of which is visceral waste. Acid ensilation might be a potential option for converting these wastes into valuable byproducts. Only little changes in the dry matter, protein, lipid, and mineral fractions occurred throughout the acid ensiling process, demonstrating the methodology' applicability. In the production of high-quality, nutrient-rich powder fish silage, fish viscera might be a good replacement for expensive fishmeal. In the preparation of fish and animal feed, it will be feasible to partially substitute expensive fish meal. Fish and other animals' growth performance in farm culture conditions should be tested with fish silage. It was necessary to conduct research on the most acceptable packaging for such a product for local marketing. The addition of BHT to acid silages made from carp fish viscera delayed the process of auto oxidation, and the low pH inhibited microbe multiplication. The p
