Throughout the year, Riboteks offers to customers juvenile fish of all age groups from both its own reproduction material and from imports. For the production of eggs, female fish are separated into special ponds, from which the eggs are taken after harvesting and their transport to the hatchery pond, and they are fertilised with the milt of the male fish. In addition, with the purpose of improving the genetic potential and the quality of the juvenile trout juvenile, eggs are purchased from the world’s foremost centres for the production of fish eggs. In this segment, the suppliers of Riboteks are the US-based Troutlodge and the Denmark-based Troutex companies. Specially selected fish eggs are transported to Ljubovija, the most advanced hatchery in Southeast Europe.
