“…There are no field or experimental studies that showed predation of Corixidae, Copepopda and animals from other taxa on Artemia in the Crimean waters. However, such pieces of evidence are available from other regions (De Los Rios & Gajardo, ; Dimentman & Spira, ; Hammer & Hurlbert, ; Hurlbert et al, ; Sultana et al, ; Wurtsbaugh, ). As an example, Corixidae Trichocorixa verticalis (Fieber, 1851) appeared and reached a large number in the Great Salt Lake (Utah, USA) after a salinity decrease (Wurtsbaugh, ).…”

“…Artemia can live in the broad salinity range, from 10 to 340 g/L, but in water bodies, where salinity is between 10 and 100 g/L, Artemia may be absent (Herbst, ; Shadrin, Anufriieva, & Galagovets, ; Williams, Carrick, Bayly, Green, & Herbst, ). Hammer and Hurlbert () asked: “Is the absence of Artemia determined by the presence of predators or by salinity in some saline waters?” Several studies have shown that predatory invertebrates (beetles, true bugs, mysids, copepods) and fish eating Artemia eggs, nauplii and adults can lead to the complete disappearance of Artemia in lakes–ponds or reduce their number by an order of magnitude (Anufriyeva & Shadrin, ; De Los Rios & Gajardo, ; Dimentman & Spira, ; Hammer & Hurlbert, ; Hurlbert, Loayza, & Moreno, ; Sultana et al, ; Wurtsbaugh, ).…”

Artemia spp. play a key role in hypersaline ecosystems. Artemia can live in a salinity range from 10 to 300-340 g/L, but in water bodies where salinity is between 10 and 100 g/L, it may be absent. Is the absence of Artemia in some Crimean lakes determined by the presence of predators or by salinity? To answer this question field long-term and experimental data collected in the Crimean lakes were used. With the least probability, the populations of Artemia existed in the lakes with a salinity of up to 50 g/L or above 300 g/L. Self-reproducing Artemia populations (all age stages) were most likely (≥80% of occurrence) noted in the salinity range of 150-200 g/L. Longterm monitoring in two lakes showed that in different years, a significant negative correlation of Artemia abundance with the numbers of amphipod Gammarus aequicauda and ostracod Eucypris mareotica was found in both lakes. This correlation can be explained by ostracod and amphipod predation on Artemia. In years without predator populations, the number of Artemia was higher by several times.Experiments showed that these amphipods and ostracods consume brine shrimps of different developmental stages. There are at least 12 crustacean species, 5 insect species, and 2 fish species, all listed in this paper, which inhabit Crimean hypersaline waters and can eat Artemia. Their predation on Artemia often is a main cause of its absence in the salinity range from 10 to 150 g/L.

“…Such knowledge is also important to develop effective technologies to cultivate Artemia in ponds. That predation by different animal species may suppress Artemia population development has been shown in many studies (Y. V. Anufriyeva & Shadrin, 2016; de Los Rios & Gajardo, 2010; Dimentman & Spira, 1982; Hammer & Hurlbert, 1992; Hurlbert, Loayza, & Moreno, 1986; Shadrin et al, 2019; Sultana et al, 2011; Wurtsbaugh, 1992). Gammarus aequicauda (Martynov, 1931) is a widespread and abundant amphipod species in estuaries, marine lakes, lagoons, and brackish waters of the Mediterranean and the Black Sea (E. V. Anufriieva & Shadrin, 2020; Balushkina, Golubkov, Golubkov, Litvinchuk, & Shadrin, 2009; Delgado, Guerao, & Ribera, 2011; Greze, 1977).…”

Gammarus aequicauda and Artemia spp. are abundant crustacean species in Crimean hypersaline lakes. G. aequicauda preys on Artemia but there was no quantitative data on this before the current study. Predation of G. aequicauda on adult Artemia was studied in experiments with two different approaches evaluating (a) the time balance of the feeding process and (b) the grazing intensity. The threshold prey concentration, when consumption began to increase with increasing concentration, was approximately 15 ind./L in 200-ml vessels and about 5 ind./L in 500-ml vessels. When the Artemia abundance reached 20-25 ind./L, there was no further influence on the gammarid consumption rate. There was a significant negative correlation between the consumption rate of gammarids and Artemia abundance. According to study results, an individual G. aequicauda may eat up to 20-24 Artemia/day. Our study suggests that (a) G. aequicauda is an omnivorous species and can significantly suppress populations of its prey. (b) The two experimental approaches used to study the feeding of gammarids on Artemia produced similar results, and both may be used to quantitatively assess relations in a "prey-predator" system. (c) The abundance of predators and prey, as well as the experimental vessel volume, may influence the feeding rate. (d) The presence of plant food resources such as the leaves of Ruppia does not influence on the predatory feeding rate of G. aequicauda. (e) The rate of prey consumption by G. aequicauda is not constant and depends nonlinearly on prey and predator abundance. (f) Cannibalism occurs in the presence of plant resources only, but not in the presence of Artemia. (g) Other gammarids react to the capture of Artemia by one of them. They swim up to the successful individual and try to take some part of the prey.

Predation of Arternia cysts by water-tiger larvae of the genus Anacaena (Coleoptera, Hydrophilidae)

Abstract: Artemia cysts are preyed upon by the larvae of Anacaena (Coleoptera, Hydrophilidae) in the wet supralittoral of the hypersaline Solar Lake near Elat . The larvae are specialized feeders of the cysts, as shown by laboratory experiments .
