Prof Md Javed Hossain Khan of the Chemical Engineering department at Jashore University of Science and Technology (JUST) has received a patent for a nano fish feed, which converts the vitamins and minerals in feed into nano form. The Bangladesh patent office approved it on 1 November.
Researchers say fish do not eat a large share of conventional feed. It settles on the pond bottom, damages water quality, produces harmful gases and raises the risk of disease and death among the fish.
Prof Khan and his team first made the feed in 2019. Because the nutrients are in nano form, they expect a small quantity to meet the needs of the fish.
He said much of the nutrient content in fish feed must be imported from India, at a cost in foreign currency. In his view, the technology will cut feed waste and water pollution and make it possible to raise more fish on less feed.
The feed has not yet reached farms. The researchers hope that with proper testing and commercial use it can open up the fisheries sector and support cleaner fish farming.
