    In recent decades there has been a constant increase in global population which generates the gigantic challenge of providing food and livelihoods to a population well of greater than 9 billion people by the middle of twenty-first century (FAO, 2018). Fisheries sector plays a key role in providing food safety and employment formany people. Global fish production has touched about 171 million tonnesby 2016 (FAO, 2018) and further increase in fish production through growing aquaculture industry is expected in coming decades. On contrast, of the overall worldwide fish production, almost 75% is only used for human consumption (FAO, 2007).The abandons from the world’s fisheries exceed 20 million tons annually(equivalent to 25% of total production) which include “non-target” species, fish processing wastes and by-products. Most of these are simply disposed off in landfills, by incineration, or dumping at sea or lands. Considering the high organic content fish waste is categorized as “certified waste” that is even more costly to dispose. Management of fish waste is coming under increased scrutiny to environmental issues (Jesperson et al., 2000) and is an emerging alarm and cost burden to whole fish industry (Anon, 2002). Considering the present and future intensity of fish production, the ultimate disposal of fish waste will turn out to be a serious problem for environment. Utilization of fish wastes help to eliminate harmful environmental aspects and improve the income for fish farmers, demanding the critical necessity to find ecologically acceptable means for reutilization of these wastes.
