Pike-perch (Sander Lucioperca L.) is considered as one of the most valuable food fishes native to Europe. Low fat content (1 – 2%), highly assimilable protein and a delicate flavour makes pike - perch meat is highly valued by dieticians. Currently, pike - perch available on the market are usually caught by fishers, mainly from Eastern Europe. However, breeding technology is still low, only a few countries (such as Denmark and the Netherlands) have established production. According to predictions of increasing consumption and environmental degradation it’ll be necessary to develop reliable technology of pike - perch reproduction as a potential for aquaculture development. Nowadays, in the EU is actively developing aquaculture in fully "recirculating" systems where water is largely reused. It is known as Recirculating Aquaculture Systems (RAS). In the EU, only the fish which is reared in the RAS may be considered as an eco - friendly product. And food safety concerns are led to the fact that some consumers are willing to pay a premium prices for safe and eco - friendly products, making such cultivation technology more profitable. The objective of this article is to provide an overview of the current status of pike - perch farming in the Russian Federation with a focus on quality of fish, which is produced in environmentally friendly way by using the RAS technology. We researched the growth features of various pike - perch generations reared experimentally in a local fish hatchery and established the possibility of introducing this species t o the market in the Kaliningrad Region.
