“…No such decrease of chironomid abundance was observed in the Ruppia thickets. Previously, it was shown that G. aequicauda consumes both Ruppia leaves and planktonic crustaceans in the lake (Shadrin et al., 2020a,2020b). Probably, in Ruppia thickets, their leaves with epibionts, both living and dead, play the main role in the composition of the gammarus diet.…”

“…In the absence of predatory animals, their role can be effectively performed by omnivorous species (Shadrin, Yakovenko et al., 2019). Several species of gammarids live in hypersaline waterbodies of different regions (Bayly, 1972; Hammer, 1986; Por, 1980; Shadrin et al., 2020b). For a long time, gammarids have been mentioned as belonging to the feeding group of the ‘shredding’, consuming plant and algal biomass, detritus and associated microbes (Friberg & Jacobsen, 1994; Gayte & Fontvieille, 1997; Greze, 1968).…”

Recently, based on results of experiments and gut content analyses, different gammarid species are regarded as omnivores or predators with a broad spectrum of consuming prey organisms (Krisp & Maier, 2005; Maier et al., 2011; Pellan et al., 2016; Shadrin et al., 2020a,2020b; Shadrin, Yakovenko et al., 2019; Syrovatka et al., 2020). In the Crimean hypersaline waterbodies, the gammarid Gammarus aequicauda (Martynov, 1931) lives, often in great numbers, and is promising to use in aquaculture (Biandolino & Prato, 2006; Guerra‐García et al., 2017; Harlioğlu & Farhadi, 2018; Shadrin et al., 2020b).…”

The ecosystems of hypersaline waters are characterized by the simplified trophic webs with the ‘loss’ of predators. In the absence of predators, their role can be effectively performed by omnivorous as Gammaridae species. In Lake Moynaki, a small hypersaline lake, Gammarus aequicauda is one of the most abundant animal species along with chironomid larvae Baeotendipes noctivagus. Both these species are promising objects to use in polyaquaculture, and this adds an importance to know their trophic relations. To analyse G. aequicauda feeding on B. noctivagus, the field and experimental studies were conducted in 2018 and 2019. In two habitats (Ruppia thickets and free water), the abundance of both species significantly differed, and in the thickets of Ruppia, the Gammarus abundance was higher, and of chironomid larvae was less. Taking into account our experimental results and chironomid larvae abundance in the lake during the study period (from 460 to 3,200 ind./m2), the authors conclude that larvae abundance did not limit the rate of their consumption in the lake by G. aequicauda, and one can consume up to 4 larvae per day. Thus, G. aequicauda could receive a diet of about 45% of their weight consuming about 2% of the available larvae daily in areas without the marine grass Ruppia thickets. In Ruppia thickets, chironomid larvae are not important food of G. aequicauda because the Ruppia leaves play a more important role in gammarid diet. With sufficient plant food resources, G. aequicauda can be successfully cultivated together with chironomid larvae.

The behavior of Gammarus aequicauda (crustacea, amphipoda) during predation on chironomid larvae: Sex differences and changes in precopulatory mate‐guarding state

The foraging behavior determines the diet size influencing the growth and reproduction of a predator and its prey populations. Amphipods play a key role in various aquatic ecosystems. Gammarus aequicauda is an abundant widespread omnivorous species and the only known amphipod species of hypersaline waters. Its predation can suppress the populations of planktonic and benthic invertebrates. Males of G. aequicauda actively eat chironomid larvae but there is no data on predatory females. Experiments were conducted to study sex‐related differences in feeding behavior including during precopulatory mate guarding (PCMG). There were significant sex differences in feeding characteristics. For females, calculations showed that maximum consumption could be 3–4 chironomid larvae per day and for males about 9–10 larvae per day. During PCMG, males did not feed and females fed as efficiently as single females. Males transported females and alone carrying the energetic costs of swimming during PCMG. Less expenditure of energy on swimming means more energy for reproduction for females. This allows more energy‐efficient use of food resources and increases the reproductive success of the population. There are currently two alternative views on PCMG among crustaceans. 1. It is a sexual conflict between males and females serving as a male adaptive strategy to achieve a female during strong male competition, while females bear many costs during the long guarding period. 2. There is also the opposite view that pairs get energetic benefits from long PCMG. Obtained data suggest that PCMG is likely to be intersexual cooperation and not intersexual conflict.
