Biofloc fish tanks: An insight into different purpose-specific designs

 Biofloc fish farming is tank-based aquaculture and specific types of tanks are used at different phases of the process. Though it is possible to convert a traditional pond into a biofloc system, it is definitely a challenging task. Free-standing Biofloc tanks are widely preferred by fish farmers as they require less space and can be set up almost anywhere, even on your terrace!


Apart from the standard circular biofloc tarpaulin tanks, raceway tanks, hatchery tanks, and transportation tanks are used to suit specific purposes. To have more clarity, let us understand the purpose of each of these specially designed tanks.

Hatchery tanks are typically used by fish hatcheries for larval rearing. These tanks can be made of concrete, FRP, or the most commonly used food-grade, non-toxic PVC material for the higher viability of fish seeds. They are usually round or square (with rounded corners), usually shallow for ease of access for daily cleaning & observation. Hatchery tanks facilitate the optimal growth of fish seeds and minimises the stress of being transferred to larger tanks.

Raceway tanks are the next-generation biofloc tanks that have a continuous water flow-through system that helps to maintain optimal water quality without hassle. These tanks are “raceway-shaped” - usually rectangular basins with a lower height than that of a standard circular biofloc fish tank. The unique design provides a larger space for the fishes to move in compared to the circular tanks. Hence, such a tank promotes better fish health and maximizes their growth.

Transportation tanks make the transfer of fish seeds from hatcheries to fish farms as well as transportation of live fish from the farms to the markets. Transportation tanks are made from premium quality, non-toxic PVC material. The PVC material used to make transportation tanks protect the fishes from jerk & jolt of long-distance transportation. KisanFlex is the only brand that manufactures transportation tanks with a special outlet-tail for easy transfer of fish out of the tanks.

Now, to find all types of biofloc aquaculture tanks and accessories under one roof may seem like an absurd idea. But dear reader, you are in luck!

KisanFlex is a brand that manufactures all types of PVC biofloc fish tanks and accessories suitable for Biofloc fish farming. Our products are made from the best quality, food-grade, and non-toxic PVC fabric for the higher viability of fish.

BioFloc- An overview

  Biofloc technology (BFT) is an innovative and eco-friendly fish farming technique that involves stock-breeding of fishes, in a micro-organism rich ecosystem, artificially created in a tank. The term Biofloc (Bio=life, Floc= aggregate) refers to clusters of micro-organisms such as bacteria, fungi, algae, protozoa, and other kinds of organic particles like fish faeces and uneaten feed. All these, together, form loose clusters of organic matter which are held together by a thin film-like substance. Ecosystems rich in Biofloc enable recycling of the waste from the fishes into an organic feed. This not only serves as a protein-rich source of food for the fishes but also maintains the optimum Carbon: Nitrogen ratio, which is a pre-requisite for viable production. The best part is, the process involves a zero to minimal water exchange within the ecosystem. This reduces the chances of water contamination and ensures a high level of bio-security. BFT was invented by Prof. Yoram ...

BioFloc Fish Farming is revolutionizing the future food needs!

Fish farming traditionally has many drawbacks. But it evolved after the ages to produce huge number of fishes in lesser space with Biofloc technology which has a competitive advantage over the traditional technique.    Current food needs in the world are growing due to population boom and the popularity of fish is drastically improved due to it, whereas the supply of fish becoming stagnant due to pollution, plastic and many factors, etc. To tackle this needs scientists have developed a technique to produce it commercially with less space, in lesser time with a less inorganic food requirement.   In the world, there are very few countries who explored the Biofloc technique and producing fish. In India, Biofloc fish cultivation is at the stagnant stage, but we are taken the Initiative to change the game overall which has changed the fate of more than 5000 farmers.    Kisanflex is a brand, who is pioneered in technology by providing all the materials requir...
