Biofloc Fish Farming

Biofloc fish farming, which has become popular among fish farmers in Goa, has established trends in the pisciculture business. 

The restricted or zero water exchange benefits the farming system, which promotes the recycling and reuse of nutrients in the culture medium. The technique, above all, decreases the use of protein-rich feed and the expense of conventional feed. 

It's an aquaculture technique that recycles turbid water in fish ponds by filtering out undesirable elements and metabolites and converting them to nutrients. 

"We have set up a biofloc fish farming facility in Ela, Old Goa, and taught fish farmers on how to transform hazardous elements in the water, such as fish excreta, into a single cell protein." This removes the need to supply pellet feed to the fish, saving millions of rupees in feed costs," a fisheries officer explained. 

The carbon and nitrogen ratio in the floc in the fish farm must be 20:1. Molasses, jaggery, sugar, and wheat flour can all be utilised as carbon sources for probiotics. As a nitrogen source, good soil, urea, or yeast can be employed. The floc is ready after 24 hours of sufficient aeration. 

It is necessary to verify the residual of 15-20 ml and the precipitate in order to test it. 

"All that is required is a tank of water, prawns that must be fed till excreta is present in the tank, and floc to turn the excreta into feed." "Anyone with enough room behind their property to do this treatment is welcome to do so," the officer stated. 

Aside from shrimp, the technique may also be utilised for fish production. While shrimp may be collected in 90 days, it will take five to six months to harvest fish. 

In addition to transforming waste into nutrients, this system has a lower water exchange rate. A 40 percent subsidy for biofloc fish farming has been given under the Central government's Pradhan Mantri Matsya Sampada Yojana (PMMSY) plan for big, medium, and small categories. 

The scheme covers all costs associated with biofloc fish farming, including the cost of putting up tanks and other necessary equipment, laying fish seeds, feeding the fish, and collecting the fish. 

As a result, Goa's department of fisheries has begun educating fish farmers in this technology. A total of 40 people are now undergoing training for the position.
