Prospective type of use:

For the arrangements of fish farms.

Fish farms are a stable and fast-growing business  which show profit not only from the sale of fish or caviar, but also from tourist destination.

Fish farms can be located along the banks of rivers where passing fish make spawning migrations.

On the way to the rivers, they are caught and delivered to fish hatcheries for final maturation and getting reproductive products (caviar and sperm).

In incubation shops, eggs are fertilized, pre-larvae are obtained, larvae are grown, and then young fish are ready. When young fish reach some mass when they can actively migrate to the sea, they are released into rivers or taken directly to the sea by motor vehicles or ships to avoid being eaten by predators.

The technological scheme of fish hatcheries includes: getting and aging of producers, obtaining fish-productive caviar and its incubation, growing of young fish.

All fish farms use clean natural water.
