The analysis of current scientific, technological, regulatory and methodical literature concerning cultivation and biotechnology of non-traditional species of fish (arctic charr) and valuable species of marine invertebrates (red king crab and sea urchin), as well as technology for complex processing of aquatic organisms has been carried out. The modern trends and problems of cultivation and use of these objects have been described. It has been shown that the freshwater form of Arctic charr has been successfully used in aquaculture in many countries while the aquaculture of anadromous (migratory) charr as an object of mariculture is still poorly developed and using this fish in mariculture is still too early. It is possible that in the near future as a result of breeding selection or interspecific crosses some forms with the required properties will be obtained. An analysis of published data suggests that there were no regular maintenance work in Russia on cultivation of sea urchins for obtaining their high-quality products to establish a basis (ingredients) of production for therapeutic and prophylactic purposes. The main efforts of previous studies on aquaculture of red king crab were aimed at the cultivation of larvae and postlarvae and rearing of mature males to reach an appropriate commercial quality. However, it should be noted that the methods of cultivation of crabs aged 3–5 years have not yet been well developed. There is also no information on the availability of accessible and relatively cheap ways to accelerate the molting process in crab, and it is known that just a long period of growing this crustacean (the commercial size is reached at age of 9–10 years) prevents the development of the red king crab aquaculture in a commercial scale. Modern processing of marine aquatic organisms should be based on a comprehensive, non-waste approach of producing traditional foods, therapeutic and prophylactic means and feed for aquaculture. The establishment of such a united technological cycle for processing red ...
