Technologies for artificial reproduction of the Azov-Black Sea shemaya Alburnus leobergi
Analysis of reproduction techniques for the Azov-Black Sea shemaya Alburnus leobergi from the simplest, developed in 1929, to the present ones, which control all the life cycle stages, is carried out. The first technology in use involved a minimum number of life cycle stages of the cultured species: capture of mature breeders on their spawning grounds during their spawning season, obtaining of reproductive products, egg incubation on besoms, wicker baskets and Seth Green incubators in the river environment, and release of embryos and larvae in rivers. Modern technologies of shemaya reproduction involve control over all the life cycle stages, from collection of breeders during autumn and spring anadromous migrations, through their domestication, obtainment of eggs with or without hormonal stimulation, incubation of eggs and retaining of embryos, rearing of juveniles and their release into a natural water body, and down to composition of industrial broodstocks and commercial rearing. All technologies for shemaya reproduction are described with regard to their differences between each other, reproduction techniques standards and their efficiency.
