Kochi, Oct 25 As part of its efforts to promote sustainable aquaculture practices, the ICAR-Central Marine Fisheries Research Institute (CMFRI) has developed eco-friendly fish feed using black soldier fly (BSF) larvae meal.
This insect protein-based fish feed is expected to reduce dependency on traditional fishmeal, which is often linked to overfishing and fluctuating prices.
Aimed at large-scale commercial production, CMFRI transferred this breakthrough technology to Amala Ecoclean, a start-up focusing on sustainable waste management and environmental solutions.
A memorandum of understanding (MoU) was signed by CMFRI Director Grison George and Amala Ecoclean Director Joseph Niclavose.
This collaboration will enable the technology to reach fish farmers across India.
Emphasising the significance of this technology, Grinson George, Director of CMFRI said this innovation promotes sustainable and cost-effective practices in the aquaculture industry.
According to the research team at the Marine Biotechnology, Fish Nutrition and Health Division of CMFRI, the feed is highly effective in maintaining the growth rate of farmed fish species, making it a viable substitute for conventional feed ingredients such as fishmeal and soybean.

Black soldier fly larvae are packed with essential nutrients, including 40- 45 per cent protein content, along with fats, amino acids, and other vital nutrients.
These larvae feed on a variety of organic wastes which make them a sustainable protein source.
After processing, the larvae are converted into a defatted meal that can be easily integrated into fish feed formulations.
This feed offers a balanced diet supporting the growth and health of farmed fish and is proven to improve the overall feed conversion ratio, which could lead to cost savings for fish farmers.
George further said this technology would help address two critical environmental concerns- waste reduction and sustainable protein sources for aquaculture.
"This aligns with global efforts to make aquaculture eco-friendly and reduce the environmental footprint of fish farming," said George.
Initial trials conducted by CMFRI demonstrated that the larvae-based feed is as effective as conventional feeds, without compromising the performance or growth of aquaculture species.
