Abstract
A brief analysis of the available technologies for growing Artemia in the world and in Russia is given in the paper. The conditions for production of Artemia in natural reservoirs with a local Artemia population are shown. The results of laboratory experiments on reducing the incubation time of cysts to 2-23 hours (instead of the standard 24-48 hours) and the inoculation of nauplii and non-hatched cysts into the brine of natural lakes with salinity of 101, 125, 225 and 333‰ are given in details. The following indicators are analyzed: the rate of hatching during incubation, the rate of hydration of cysts during incubation and dehydration in brine; the survival rate of nauplii in brine, the possibility of hatching nauplii from cysts in brine with different salinity. The results of long-term observations of the survival of Artemia crustaceans in the brine of the lake in the absence of feeding are also presented. It is possible to reduce the incubation time to 6-20 hours is concluded in the paper. The dependence of the duration of incubation of cysts on the temperature, quality of cysts and salinity of natural brine was noted. To determine the optimal incubation time of cysts the formulas for calculating T90 according to the temperature and salinity of brine for cysts of different quality are given.
