The fish reproduction takes place around the year in separate hatcheries, that provide the highest hygienic standard to avoid any danger of infection. Here not only the parental fish is kept in aquaria for better control, the fertilized eggs and larvae too.

A few days after the hypophyses of the chosen adults, the fish is singularly tranquilized and after that they are carefully prepared for the collection of gametes.

The collection of the female`s eggs has to be repeated several times, since the eggs are not mature all at the same time. It is important to work completely dry, otherwise the eggs would glue together instantly and you couldn`t remove it from the collection bowl.

Following the mixing of sperm and eggs in exact proportions they are divided into the single aquaria.

After a few days the larvae are hatching, they firstly adhere, but then they start freely. After using up the yogbag the fish are fed with Artemia and then bit by bit with dry feed.

The bigger the fish, the more space is needed for most advantageous development. To fit this need hatchery basins of different sizes had to be constructed.

The Koi-carp is sorted and selected in specific time intervals to have fish of different quality and size in different basins.
