Red king crab (Paralithodes camtschaticus)

    Red king crab Paralithodes camtschaticus Tilesius, 1815.Red king crab belong to the order Decapoda, suborder Anomura, family Lithodidae (craboids).
    Red king crab is the most studied of commercial crabs. The biology of the red king crab is described in detail in the works of L.G. Vinogradova (1941, 1946, 1947). The literature on red king crab until the beginning of the 20th century is mostly descriptive (Kovacheva, 2008). The female red king crab breeds annually (Stevens 2006b, Stevens and Swiney 2007).

    For artificial reproduction, two methods were developed: collector and factory.
   The collector method is based on the collection of fry on cages and collectors with a view to further the growth of juveniles at sea (Maslennikov, 1996, 1998; Maslennikov et al., 1999; Grigoryeva, Fedoseev, 2000; Fedoseev, Grigoryeva, 2001, 2002a).

In Alaska, an analysis was made of the intestinal contents of red king larvae crab in vivo and as a result in the digestive tract of larvae microalgae of the genus were observed Chaetoceros, Skeletonema, and Thalassiosira (Paul et al., 1989, 1990). Laboratory king crab cultivation held in Norway (Mortensen, Damsgard, 1996). The study was conducted growth, mortality, and food artificially is grown preferences crab. (Stevens et al., 2008).

    The successful experience of the artificial reproduction of red king crab on the coast of the Barents Sea (Kovacheva et al., 2010). As a result, it was obtained and successfully 200 thousand individuals of king crab fry were released into the sea.
    Adaptation of biotechnology for artificial reproduction and cultivation of larvae and juveniles of red king crab to the conditions of the scientific and experimental module Marine Bio station “West” (Borisov et al., 2012). As a result of the experiment, the authors obtained a viable larva in the amount of 1,450 thousand individuals. The NSCMB FEB RAS employees are actively studying the development of the early stages of the larvae and fry of the red king crab on the basis of the scientific and experimental module Marine Bio station “West”.

Questions such as studies of the effect of feed composition on red king crab larvae survival Paralithodes camtschaticus when grown in controlled conditions. (T.A. Gevorgyan, S.I. Maslennikov 2017). Research the influence of environmental factors during cultivation king crab paralithodes camtschaticus in the period of development of zoea 1 to glaucoma in controlled conditions (T.A. Gevorgyan 2018). Studies influence the landing density of king king crab Paralithodes camtschaticus when grown under controlled conditions (T.A. Gevorgyan, S.I. Maslennikov 2018). Research On Hatching And Development Of Red King Crab Larvae Under Controlled Conditions (Gevorgyan T.A. Maslennikov S.I., Botsun L.A., 2019)

The impact is currently being studied. Probiotics for survival and growth king crab larvae. And the influence of the so-called "Green Water" on growth and survival of crab larvae. It is planned to study the influence of these factors for growth and survival of fry crab.
