What Is Biofloc Shrimp Farming?
Most of the world’s shrimp are farmed in large, outdoor ponds. Shrimp farmers fertilize their ponds to create an algal bloom that feeds the eyelash-sized shrimp. There are good things and bad things about farming shrimp in ponds. Ponds are a very low-input method of shrimp farming–there is less labor, less feed, and generally lower costs associated with farming shrimp in ponds. However, ponds are also particularly susceptible to changes in the weather, predators, and disease outbreaks, and they cannot produce nearly as many shrimp as intensive systems.
Biofloc shrimp farming replaces the algae of outdoor shrimp ponds with beneficial bacteria and protozoans. Like algae in outdoor shrimp ponds, the microorganisms in our biofloc are a feed source. These microorganisms not only act as a midnight snack for the shrimp, but also provide biological filtration for our shrimp by metabolizing nitrogen waste products. Think of them as the trees in our environment, but instead of recycling harmful carbon dioxide to the oxygen we breathe, the biofloc recycles a harmful form of nitrogen to a neutral form of nitrogen. Many studies have shown that shrimp grow better in biofloc systems. Scientists also hypothesize that the biofloc bacteria outcompete harmful, pathogenic bacteria like Vibrio spp. that can cause shrimp and human diseases, similar to the probiotics you may have heard about.
All of our shrimp at Dairyland Shrimp are grown in an indoor biofloc system. We believe that this method is the next step forward in producing shrimp. You can eat our shrimp knowing they are happy, healthy, and harmless to the environment.
