The employees of the “RPC of Fishery” LLP, within the the “Artificial reproduction and cultivation of fish stock of Eurasian carp (sazan) for the purpose of its further sale for stocking natural reservoirs of the Republic of Kazakhstan” commercialization project, provide scientific support for reproduction of sazan on the base of a private partner, “Kapshagai NVH-1973” LLP.

Currently, work has been carried out on the selection of gender products from the producers of sazan. After fertilization, the caviar were transferred to the hatchery for further incubation.

During the work, the larvae will be reared under controlled conditions of RAS and then they will be released into ponds for further cultivation and sale of sazan stock for fish stocking of natural reservoirs.

At this stage, the employees of the “RPC of Fisheries” LLP observe the process of sazan embryogenesis.

In the photo – the stage of the beginning of pigmentation of the eye of the fish:

The body of the embryo makes weak movements. At the age of a little more than two days, segmentation of the caudal region is observed. By this time, body segmentation is almost complete. Black pigment appears in the eyes. The parts of the brain now look different. Otoliths are formed in the ear capsules.
