Here Is A Complete Guide On How to start biofloc Fish Farming.
Based on interviews with some of the earliest developers and adopters of biofloc, including Djames Lim from Singapore (CEO of the Lim Shrimp Organization), Khoo Eng Wah from Malaysia (managing director of Sepang Today Aquaculture Centre), Barkah Tri Basuki from Indonesia (Founder of Banglele Indonesia) and Dr Nyan Taw from Myanmar (senior shrimp farming consultant), The Fish Site presents a practical 10-step guide to help you incorporate biofloc principles in your shrimp or tilapia operations.
The costliest factors in aquaculture are high-quality feeds, filtration systems and the investment needed for ample space to grow target species. With continuously rising production costs, farmers and researchers are looking for alternative ways to produce more seafood while utilising fewer resources.
Originally conceived as a natural way to clean water, biofloc systems are becoming increasingly popular as a low-cost means of cleaning the culture water of fish and shrimp farms while simultaneously providing an additional source of feed. Best of all, implementing biofloc principles requires little investment – as only sunlight, a carbohydrate source and plenty of aeration are needed.
It’s important to understand that biofloc systems and their underlying principles are relatively new and complicated aquaculture concepts. There are still many unknowns and much remains to be discovered. We encourage readers to conduct further research and to share their experiences to maximise everyone’s chances of success. And don’t forget to check out the training reference section at the end of the article for some very useful links.
Learn How To Start Biofloc Fish Farming?
By recycling proteins, biofloc systems overcome concerns associated with high animal-stocking densities and low filtration capacity – like decreased water quality and increased risk of disease outbreaks. In traditional farming systems, only about 25 percent of the protein content of feeds are actually utilised by farmed species.
By converting ammonium into microbial proteins that can be consumed by filter feeders, biofloc systems are able to double this figure, saving farmers big money. Biofloc systems reduce the spread and effectiveness of pathogens while simultaneously improving fish health through better water quality and bolstered feed availability. As such, biofloc systems can give us a natural way of producing more seafood sustainably, while concurrently improving farm profitability.
More of Asia’s top shrimp-industry players are shifting to biofloc. As Djames Lim, CEO of one of the largest shrimp farming operations in the region, explains: “Without biofloc our company wouldn’t be able to achieve its ambitious growth rates without compromising environmental integrity and animal-welfare principles. This system is a win-win situation for all stakeholders.”
Step 1: Tank or pond set-up
Though it’s possible to convert traditional fish ponds without any liner into a biofloc system, it’s a challenging task. Microbes, minerals and heavy metals naturally based in the soil easily influence the parameters of the pond water and can affect the natural processes underlying the biofloc system.
As Khoo Eng Wah, managing director of the Sepang Today Aquaculture Centre (STAC) in Malaysia explains: “For those new to biofloc, it’s best to start with lined ponds, concrete ponds or indoor tanks wherein soil has no influence over water parameters or biofloc processes.” In most tropical countries, indoor systems have a big advantage. “As we experience heavy rainfall, alkalinity and pH are easily affected in outdoor systems. Covered ponds are good options.”
Step 2: Aeration
After you have selected the right pond or tank set-up, it’s time to work on the aeration system. All biofloc systems require constant motion to maintain both high oxygen levels and to keep solids from settling. Areas without movement will rapidly lose oxygen and turn into anaerobic zones which release large amounts of ammonia and methane.
