AGARTALA, Sept 18: Tripura has taken a significant step toward lowering aquaculture costs by developing an organic fish feed made from Wolffia globosa—the world’s smallest aquatic plant.
The initiative is a joint effort of the College of Fisheries, Lembucherra, and the Directorate of Biotechnology, with financial backing from the Department of Biotechnology, Government of India.

Science and technology minister Animesh Debbarma unveiled the project during a workshop on biotechnology-based fish feed, highlighting its potential to transform fish farming in the state.
According to the minister, trials have shown that Wolffia-based feed not only reduces dependence on expensive commercial feed but also promotes faster growth in species like Katla and Rui.
“Conventional feed costs nearly Rs 100 per kilogram, while Wolffia can be grown naturally in pond liners and harvested within a week. Researchers have confirmed its superior protein and nutritional content compared to market feeds,” he said.
The Directorate of Biotechnology has been tasked with conducting village-level training and demonstrations to popularise Wolffia cultivation.
The College of Fisheries has also confirmed that the plant’s bioactive compounds could have wider applications in nutraceuticals and functional foods.
Officials noted that Wolffia can be cultivated in small ponds and tanks with minimal inputs, making it an accessible and sustainable option for marginal fish farmers.
Beyond reducing costs, the initiative is expected to encourage farmers to produce their own feed and explore new livelihood opportunities.
”This project has the potential to provide a long-term solution to fish feed shortages while strengthening the economic resilience of Tripura’s fish farming community,” minister Debbarma added.
