“…These values are higher than the values recorded in the parthenogenetic population of Aral Lake (1-190 ind. m -3 ) (Arashkevich et al, 2009;Marden et al, 2012) and quite lower than the values recorded in southwestern Siberia (100-10,000 ind. m -3 ), Urmia (3000 ind.…”

“…The Acıgöl population was consistently more productive per unit volume than the other lakes. In this study, the Artemia population size and ontogenetic structure in all lakes showed monthly variations; this is quite typical for Artemia populations in the temperate zone, such as the Great Salt Lake (Wurtsbaugh and Gliwicz, 2001), Urmiah Lake (Van Stappen et al, 2001), and the Aral Sea (Marden et al, 2012). Survival and reproductive success of Artemia are influenced by multiple biological, physiological, chemical, and physical factors but the most important variables that control the life cycle of populations and affect the density are temperature and salinity (Vanhaecke et al, 1984;Lenz and Browne, 1991;Browne and Wanigasekara, 2000).…”

“…Our brood size data for these three lakes in the range of 14-98 are not extremely low or high when compared to the field values of other populations. For example, in the Artemia populations from southwestern Siberia, brood size values fluctuated in the range of 10-35 (Van Stappen et al, 2009), while Marden et al (2012) reported field values in the range of 20-45 for the Aral Sea. In other research on A. franciscana from the Great Salt Lake average brood sizes were recorded as 64-81, whereas Wurtsbaugh and Gliwicz (2001) reported a lower brood size of 15-30 for the Great Salt Lake population.…”

The objective of this study is to provide information on the parthenogenetic Artemia populations in some hypersaline lakes of Anatolia (Tuz, Bolluk, Tersakan, and Acıgöl). Sampling studies were performed for abiotic factors and population parameters between November 2009 and October 2010. During the survey we focused on the local Artemia populations to investigate population dynamics, reproduction, brood size, and cyst and naupliar biometrics. Generally, the Artemia habitats in Anatolia were relatively shallow, and thus they were subject to major seasonal fluctuations. Dramatic declines in population size in Tuz and Acıgöl Lakes were found during this study. All Artemia populations were parthenogenetic and brood sizes of females showed significant differences among the populations (P < 0.05). The largest brood size was observed in the Acıgöl population and it may be concluded that local conditions for reproductive success were more adequate in this population. Substantial differences among populations were revealed during the studies on cyst and naupliar biometry. Cyst diameter mean values ranged from 231.8 to 266.9 µm. The cyst diameters for the Acıgöl population are determined as the smallest in these populations and among the smallest values recorded in parthenogenetic populations. The total length of newly hatched nauplii ranged from 484 to 512 µm for these populations.

“…The Aral Sea, formerly the 4th largest lake in the world, is such case. Currently, there is a new large population of Artemia in the South Aral Sea, which is a separated part of the former Aral Sea (Arashkevich, Sapozhnikov, Soloviov, Kudyshkin, & Zavialov, ; Marden et al, ). This paper is about Bay Sivash, another such case.…”

Bay Sivash was a hypersaline lagoon but after construction of the North Crimean canal, it shifted to a brackish water state. In 2014, the canal was closed; a salinity increase started. In 2018 and 2019, plankton sampling was conducted in the bay at salinity from 30 to 100 g/L. A decrease in taxonomic diversity and total abundance was observed. Before November of 2018, Harpacticoida and chironomid larvae were the most common and abundant groups. Different stages of Artemia were consumed by invertebrate predators and fish at that time. In November 2018, Artemia stages contributed more than 90% to total zooplankton abundance at all sites excepting with salinity lower than 55 g/L. In June–July 2019, adult Artemia were at all sites with salinity higher than 82 g/L when there was no suppression by predators. A self‐sustaining Artemia population in the bay may recover in 2 or 3 years, when the average salinity would reach 80–90 g/L; total abundance of the active Artemia stages may reach 3000–5000 ind. M−3 between April and August. The lagoon may become one of the world main habitats of Artemia having a significant impact to provide world's supply by its cysts.

“…The conditions for the formation of a stable population of Artemia became favorable when with salinization of the Large Aral Sea its competitor C. aquaedulcis, which was dominant in the zooplankton, and fish finally disappeared from the fauna of the sea. As a result, by the beginning of the 2000s, Artemia had become a dominant form of free-living plankton invertebrates (Mirabdullayev et al, 2004;Marden 2012) in the fauna of hyperhaline residual water bodies of the Large Aral Sea.…”

Based on the literature and studies carried out by the authors over more than 30 years, an analysis of the fauna of crustaceans of the Aral Sea is presented. The faunal composition, the changes that have taken place since the 1950s, and the relations to the salinity factor are considered. Crustaceans in the Aral Sea make up about one-quarter of the species diversity of Metazoa. They are represented by freshwater, brackish water, and marine species, as well as halophiles from saline continental waters of the arid zone. The first changes in the composition of the crustacean fauna of the Aral Sea started even before its modern regression. They were the result of deliberate, as well as accidental, introductions of a number of initially absent species of invertebrates and fish. Since the 1960s, the main cause has become the rapid change in salinity. As the salinity has increased, the species diversity of the crustaceans has sharply decreased due to extinction, first of freshwater and then of brackish water species. After the level of the Aral Sea fell and it was divided into two parts, the Small Aral and the Large Aral, further evolution of these residual water bodies proceeded in different directions. As a result of the construction of the dam in the former Berg Strait, it became possible to decrease the salinity of the Small Aral Sea and gradually restore the crustacean fauna. The Large Aral has now turned into a hyperhaline water body inhabited by only a few species of crustaceans.
