Kufos seeks to leverage Biofloc method for Vannamei agriculture

Kerala University of Fisheries and Ocean Studies (Kufos) seeks to deploy biofloc method to farm Vannamei shrimp even as COVID-19 restrictions and job losses push more people to work independent in agriculture and related activities.

Vice Chancellor K. Riji John said that biofloc technology has now been standardized so that those with limited acreage can engage in fish farming using this technology. It has been accepted among aquaculturists, with the Department of Fisheries offering support to the program.

The fish that is now widely cultivated using this technology is the Genetically Modified Farmed Tilapia (GIFT). Such businesses can be turned into economically rewarding businesses for farmers by transferring candidate species to Vannamei shrimp, he said.

The biofloc model is an intensive aquaculture system and is considered to have an advantage over conventional systems, as the normally harmful wastes produced in conventional aquaculture can be turned into fish feed.

Vannamei’s experimental farming began in the state about six years ago at Kufos’ initiative. Exotic white-legged shrimp are native to the eastern Pacific Ocean and have been shown to be adapted to the brackish water conditions of Kerala.

Extensive cultivation of Vannamei has been undertaken in Andhra Pradesh, West Bengal, Orissa, and Tamil Nadu, among other coastal states.

The ICAR-Central Brackishwater Aquaculture Institute in Chennai even launched a mobile application, Vanami shrimpapp, to disseminate information on shrimp farming.

Vannamei’s export accounts for a substantial share of seafood export revenue from India, with the United States and countries in Southeast Asia and the European Union accounting for the bulk of the business.
