The global population of the world is increasing and so is the demand for animal protein. Aquaculture plays an important part in meeting the demand for protein and balancing the economy by promoting employment. Biofloc fish farming is considered a “blue revolution’’ since the nutrients can be recycled and reused in the culture. Biofloc fish culture is considered an environment-friendly technique for improved quality and increased production of fish.
Biofloc is mostly carried out in ponds/tanks that aggregate living or dead particulate matters, bacteria, phytoplankton, and more. The use of microbial processes inside the tank provides food resources for cultured organisms simultaneously acting as the water treatment.
What is Biofloc Fish Farming?
Biofloc is a Profitable Fish Farming Method. It has gained a lot of traction as a credible option to open-pond fish farming all over the world. It is a low-cost method of converting hazardous compounds for fish, such as ammonia, nitrate, and nitrite, into feed. The idea behind this method is to recycle nutrients. Apart from being a profitable method for fish farming, it also allows the farmers to save a considerable amount of money by reducing the cost of various other expenses.
How Biofloc helps in cost saving & increasing income?
Fish farming requires a lot of capital and necessary techniques in place. It is a profitable method of farming because it cuts down extra cost, leveraging big savings. Biofloc cultures allow the farmers to save money on operational cost, feeding cost, cost of vast lands, disposal, and discharge of waste.
In aquaculture, the major cost comes from the feeding ingredients for fish.. However, with the help of biofloc, it can be recycled into feed, which will reduce the cost of expensive high-protein fish feed. This is not the only plus point of biofloc system, it also helps in reducing the unwanted spread of pathogens and improves the health of the fishes. The advantages of Biofloc culture just does not end here.
Advantage of Biofloc farming
- Judicial use of water and land
- It’s eco-friendly
- It reduces environmental impact
- High productivity with enhanced survival rate, better growth
- Limits the water pollution and reduces the spread of pathogens
Fish Feed in Biofloc fish culture
In a traditional fish farming method, the fishes consume very little amount of feed. The remaining feed is dissolved and degrades to become toxic metabolites. The toxic waste affects the quality of the water in the tank, which later affects the quality and production of the fishes.
Since feed is an important part of fish farming, a balanced amount of feed is necessary every day for the desired growth. In the biofloc farming technique, the wasted food and the fish excreta are converted into fish feed solving all the problems of water pollution. The process improves the water quality and gives a healthy environment for the fishes to grow.
Biofloc fish farming has allowed various large and small fish producers to reach successful results at a low cost. The technique used in this production is easily available to the farmers at a low cost.
