| Summary: | Purpose: This study was conducted in the context to recycle the agricultural wastes among fruits and vegetable peels in a biofloc system inhabiting grass carp fingerlings (Ctenopharyngodon idella). Fish has attained a vital place in the food industry, but the major problem is costly fish feed along with water management.
Method: Banana, potato and orange peels were incorporated as cost effective agricultural wastes for the biofloc development and its effect on fish growth was analyzed. Three experiments in triplicates were conducted for the three agricultural wastes to raise biofloc in 90 L glass aquaria and run parallel with control. Fingerlings were fed on the developed biofloc for 60 days.
Results: Higher fish growth (p<0.05) that is gain in weight (4.08 ± 0.41) and gain in length (3.14 ± 0.37) was obtained in aquaria fed on banana peels than other agricultural wastes and control containing 39% protein, while the microbial screening showed six different types of bacterial isolates with 1.65 × 105 CFU m L-1. The feed conversion ratio (FCR) and percentage specific growth rate (%SGR) also improved in fingerlings reared on banana peels biofloc-based aquaria.
Conclusion: Consequently, banana peels can be recycled as the cheapest agricultural waste in the biofloc system.
Research Highlights
· Commencement of recycling and utilization of agricultural wastes that can serve as sole carbon source in animal nutrition and hence improves the environment quality.
· Introduction of cheapest fish feed by using agricultural wastes that replaces fully commercial feed to make it cost effective.
· Initiation of a system that recycled agricultural wastes incorporating in fish feed to get better growth at cheapest prices.
· Waste water treatment by adopting biofloc technology that minimized the water exchange in fish aquaria because ammonia produces as fish wastes has been recycled and converted into useful form by bacteria.
· It is a novel work to choose as a start up of biofloc business that is cheap and requires minimum area. It is also helpful in making the environment clean by utilizing agricultural wastes.
· This research work better meet the journal scope “recycling and reusing of organic wastes” because it provides novel information regarding recycling of agricultural wastes, its utilization in animal nutrition and environmental issues.
