(TWL), pioneer in the Indian Aquaculture Industry with integrated offerings of hatchery, shrimp feed, farm care products and shrimp processing & exports reported a positive performance for the quarter ended June 30, 2026. Business Performance Overview The quarter was supported by stronger traction in the Shrimp Feed business, while the Processed Shrimp business continued to gain momentum. The Farm-care business also maintained its growth trajectory. Managing Director’s Message Commenting on the results, Mr. Ramakanth V Akula, Managing Director, said: “The performance during the quarter was encouraging, and while we are pleased with this progress, we remain mindful of the pressures the aquaculture industry continues to face. The sharp rise in key feed raw-material costs, particularly fishmeal and soybean meal, remains a matter of concern. Higher input costs weigh directly on farmer economics, and getting the balance right between feed costs and farmer returns is important for the health and sustainability of the entire value chain. On the export front, the easing of the tariff situation has enabled the commencement of exports to the US market, which we see as a positive development. We will continue to monitor developments in the market and work towards leveraging these opportunities in a measured manner.
