“…In Kazakhstan, in such lakes as Maraldy, Tuz, Kazy, Kalatuz, salinity reaches 250-300 g/l, and the survival threshold is 360 g/l concentrations [2,6]. Externally, artemia, living with a high salt content, differ from those living in reservoirs with a low level of salinity by the color of skin [9].…”

“…Most often, artemia nauplii are used in feeding [1], but decapsulated eggs are also among the valuable feeds, the biomass of juvenile and adult stages of artemia crustaceans is used to feed juveniles and grown-up fish [2,3]. Artemia (at the stage of nauplia) contain a large amount of vitamins, essential polyunsaturated fatty acids, amino acids, biogenic and microelements.…”

“…According to the literature data, water mineralization affects both the morphometric parameters of crustaceans and, in general, the quantity and biomass of artemia, for which the optimal salinity values lie in the range of 100-200 g/dm3 [2,6]. Also, water salinity has a great influence on the growth and reproduction of artemia crustaceans, both in the natural environment and in aquaculture [7,8].…”

The work is devoted to the study of influence of salinity level at the rate of hatching, productivity and morphometric parameters of artemia in aquaculture. The cultivation technology of Artemia salina in aquaculture for obtaining live starter feeds has been used in practice for a long time, but it is still far from perfect, since it is developed for a certain averaged artemia, and in practice we have to deal with specific species and their ecomorphs (ecological morphotypes), the optimal conditions of cultivation of which differ in many ways. One of the most important factors determining the development of artemia is the salinity of the environment. The aim of our study was to assess the effect of the salinity level of culture medium at the rate of hatching, productivity and morphometric parameters of artemia grown in industrial aquaculture. The results of the study showed that with an increase in the concentration of salt in the solution for cultivation of artemia, metamorphosis of the free embryo in nauplia is prolonged and the percentage of their yield decreases. Differences in the average population indicators of length and body weight of nauplia were found, which tended to decrease with an increase in water salt concentration. When studying the absolute fertility of female artemia grown at different concentrations of salt, it was found that an increase in water salinity in reproductive age of females makes it possible to increase their absolute fertility when breeding in artificial conditions.

The content of nutrients and biogenic elements in enriched artemia salina

et al. 2023

The work is devoted to the development of technology for enriching artemia with biologically active substances. The development of technology for enriching artemia with biologically active substances is important as an opportunity to obtain starter feeds for aquaculture with the desired properties. High content of high-grade protein, vitamins, amino acids, fatty acids, biogenic elements is of great importance. During artificial cultivation of artemia in a closed cycle in the conditions of aquaculture, there is a problem of sufficient accumulation of substances in its body that provide high nutritional and biological value. To solve this problem, we have developed a technology for enriching artemia with biologically active substances at the nauplium stage. The enrichment of artemia with vitamins, amino acids, probiotics, adaptogens, essential lipids allows us to create a new generation of bio-feeds containing a living symbiotic microbiota and ingredients capable of forming balanced complex of functional nutrition for fish. The aim of the study was to evaluate the biological and energy value, the content of proteins, fats, carbohydrates, moisture, ash, micro- and macroelements, heavy metals in artemia at different stages of ontogenesis against the background of its enrichment with a complex of biologically active substances. Intact and enriched cysts, intact and enriched decapsulated artemia eggs, enriched artemia nauplii were analyzed. It was found that against the background of enrichment with biologically active substances, the indicators of metabolic energy increased, the mass fraction of crude protein, the mass fraction of fat and the content of minerals and biogenic elements increased.

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.
