The water-exchange rate also influences the oxygen and ammonia concentrations in the water and thus ultimately the possible fish densities in the tank. This depends, for example, on how fast sediments settle in the tank and whether or not these can be completely washed away. The higher the water-exchange rate, the more often the water in the tank can be renewed. The two types differ not only in their design but also in the realisable water-exchange rates. However, irrespective of the design (which is often the result of compromise), nearly all farming tanks can be divided into two basic types: channels, also known as raceways or flow-through systems, and round tanks. If sturdier materials are needed, farmers should choose steel or concrete (coated or non-coated).īasins and tanks are available in all sizes, in a wide range of designs and for various applications. Because plastics lack natural stability, however, they are best used for smaller tanks measuring up to ca. This category also includes tanks made of PVC or PE film that are suspended on stable frames. In practice, plastics are used, such as polyethylene, fibreglass, or polyresin, a sturdy resin compound made of sand or ground stone mixed with synthetic resin. The surface of the material should not cause skin abrasion if fish rub against it. When choosing tank materials, however, there are some areas where compromises are not possible, because the material has to be watertight, rustproof, non-toxic, and should keep its shape when filled. Farmers are often forced to find an acceptable balance between what they would like and what is actually possible. Local energy costs can also influence tank construction. Anyone planning to use salt water in their facility should note that the materials for tank construction are not the same as those required for freshwater tanks. The decision for or against any of these solutions depends on the fish species as well as on specific production regulations, climatic conditions, concrete environmental requirements, and of course on the financial scope of the investor. Or they can be partly sunk in the ground, which sometimes makes work easier. There are also “hanging” funnel-shaped tanks, which can stand either on supports or on the ground. The tank floor can be flat or slope conically towards the centre. They can have rectangular or round bases they can be cylindrical or cone shaped and stackable in one another. The shapes of the containers are no less varied than their applications. They are used for the production of live feed and as grow-out tanks, as transport and quarantine containers, and for holding, presentation, or short-term fish storage. They serve as storage tanks for adult fish and as hatchery tanks for young fish. These basins make land-based farms largely independent of the local aquatic conditions.īasins and tanks are used not only here, however, but in all of the different aquacultural processes. The water flows into basins or tanks, which then become “mini water bodies” in which fish live and grow. They get their water supply from rivers and small streams, or springs and subterranean water that is pumped from the earth. More and more products are produced in land-based facilities that operate independently of the sea or open inland waters. Although this is not incorrect, it is only one of the many options for farming fish and seafood today. When people think of aquaculture, the first things that come to mind are ponds or net cages, like those used in salmon farming in Norway. Every model has certain advantages and disadvantages, and no universal solution meets all aquacultural needs. Tank design and construction depends heavily on their intended application. They are available in various shapes and sizes and can be made from different materials. Proportionately the dosages should be calculated and administered.Many aquacultural tanks are made of plastic with relatively low stability, which limits the size of the tanks.Īll aquacultural facilities need tanks, basins, or other containers to hold the water and the fish. In an approximation, one acre equates to 0.4 hectares and 4047 Square Meters. The dosage of aquaculture products if prescribed in acres or hectares, it needs to be converted to the relevant unit of measurement, as applicable per the local system.

For e.g., a Square Meter for the Surface Area and Meter for the Depth. The tank volume equates to the product (i.e., multiplication) of the tank’s Surface Area and its Depth, while both factors will have the same measurement unit. The need to do the volume calculation is to estimate the dosage of aquaculture products like OZPOLISH Bio-Cure Professional, OZPOLISH De Ammo, and OZPOLISH De Nitra. Volume calculation for any aquaculture or biofloc tank could be a little tricky. HOW TO calculate the volume of any aquacultural tank. HOW TO calculate the volume of any aquacultural tank
