Any entrepreneur engaged in fish farming, tries to use every liter of the reservoir as useful as possible, getting the maximum yield of the product. But for this insufficient natural development on natural nutrition. For fast and efficient fish farming, a properly balanced and nutritious food is very important. In modern commercial fish farming, at all stages of cultivation they use special compound feed for fish.
Pond and industrial fish farming
Fish farming in pond fish farming is carried out in natural or artificial reservoirs. In order to maximize efficiency and significantly increase the fish yield per hectare of water, an intensive form of fish farming is used, in which the carp and other herbivorous species (units / ha) are densely planted and fully fed with fish feed.
Industrial fish farming involves the cultivation of fish in cages and pools with a dense landing. With this method, the cultivation is carried out at a high speed of water circulation and full feeding with compound feed for fish. In industrial fish farming, the largest increase in output.
Combined feed groups for fish
For feeding with different methods of cultivation, there are three groups of animal feed:
- Compound feed for fish can serve as a mixture of grain cereals and legumes, bran. This is the most affordable type of feed. Most often used for feeding cyprinids in ponds without pre-treatment. The main disadvantage is poor balance. It is heard from the shore.
- Feed mixtures or granular feed. Well balanced in nutrients, vitamins and minerals. The degree of balance depends on the choice of raw materials. Such feed for pond fish is suitable for use in pneumatic feeders and feeders.
- Extruded feed. Produced by specialized enterprises. Complete feed of high quality and with appropriate value. They are used exclusively in industrial fish farming.
Compound feed for fish: composition and requirements
The balance of feed by nutrients and minerals not only ensures rapid growth of fish, but also prevents various diseases. The composition of modern feed can include up to 40 components. The recipe is selected for a specific type of fish, taking into account its age. The composition of the feed includes minerals, elements of animal origin, cereals, legumes, meal, etc. Compound feed should be:
- Durable, do not crumble during overload and transportation.
- Water resistant. If it gets into water for some time, keep in shape.
- Valuable in batteries.
According to the chemical composition of the feed in different percentages, depending on the formulation, must be present:
- Protein. Valuable in its amino acids. Especially useful for young animals.
- Fats of various origins are a source of energy.
- Carbohydrates (fiber).
- Minerals.
- Vitamins, water and fat soluble.
- Biologically active substances - premixes and enzyme preparations.
