Project description: Cylindrical and tubular structures of artificial nets-hatchers for salmon spawn, which make it possible to eliminate costly factory cycle of young fish breeding, have been worked out. Testing of nest-hatchers for salmon spawn in different rivers by terms of hygrology: Umba, Indera (Kolsky peninsula), Lososinka, Sunna (Karelia), and Oulunyoki (Finland), proved efficiency in reproducing high quantity of wild (viable) young salmon, in waters where natural population had been small or completely lost.
 Basic characteristics of the project: Artificial nest-hatchers are made out of fiber-glass plastic and polymers. For the first time silicone carrying base for underdispersion of spawn and alevins was used. Constructions are made for multiple usages, self-cleaning from sand and silt, and use of naturally cleaned stream underflow for wash-off of spawn. Nests are meant for long term usage (8-9 months) in rivers with long period of freezing, do not need upkeep.
Field of application: Fish breeding, river recultivation after wood floating and construction of hydro power stations, recreation and reproduction of population of salmon in rivers with small or completely lost population.
Marketing forecast: Users: regions with developing recreational fishing tourism (the North-West of Russia, the Far East, Scandinavian countries), implementing programs for preserving and rational exploitation of salmon.
Development stage: Successful appraisement of utility model and its modifications for rivers of different types, development of models for simplified use, search for partners for setting up a production. Utility patents ¹ 38532 (2004), ¹ 46626 (2005) and ¹ 71509 (2008) have been obtained.
Requirements of the project: Financing accounts for 1 million RUR. Technological design for different rivers’ hydrological conditions, mass testing and introduction are underway.
