“…Because D. birgei also grew well with the limnetic seston, the fact that this species was not found in the limnetic zone may be related to a greater abundance of pelagic predators, mainly Chaoborus larvae, which feed on microcrustaceans (Arcifa, 2000;Castilho-Noll and Arcifa, 2007), including all stages of D. birgei (TCS Ferreira et al unpublished data). Species of Diaphanosoma are known as thermophilic that adapt to higher temperatures and prefer warmer areas (Lazareva, 2012;Choi et al, 2015), but the lack of temperature difference between the littoral and limnetic zones of the lake does not support this hypothesis.…”

The occupation of the littoral and limnetic zones by planktonic species has led to questions about whether littoral macrophytes would be a suitable habitat or refuge. These questions guided our field and laboratory studies on the spatial occupation and the food suitability for microcrustaceans of a shallow tropical lake. Replicated zooplankton samples were collected over 18 days, at intervals of 3 days, at three zones (the middle and edge of the stands of the emergent macrophyte, Ludwigia sp., and the limnetic zone). Some species, such as the cladocerans Diaphanosoma birgei and Daphnia ambigua, showed preference for the littoral zone and the limnetic zone, respectively. Copepodites, and adult copepods Thermocyclops decipiens and Tropocyclops prasinus meridionalis are mainly limnetic dwellers. The size of the cladocerans Ceriodaphnia richardi and Daphnia gessneri did not differ between the zones, nor did the clutch size of the former species; smaller individuals of D. ambigua were found within macrophyte stands. In laboratory experiments, the seston of the three zones did not negatively affect the development of the cladocerans C. richardi and D. birgei. On the contrary, the seston of the middle of the macrophyte stands promoted better growth rates of both cladocerans and some of the life table parameters of D. birgei than the seston of the other two zones. Food quantity and quality are not negative factors to microcrustaceans in the littoral and limnetic zones. The preference or indifference of microcrustaceans to habitats may be part of their adaptive strategies regarding other factors, including predation.

“…The bottom layer is not suitable for the foraging activities of fish because there is little light coming in. As the bottom layer is avoided by fish, it can act as a refuge for the survival and stable population growth of the prey cladoceran species [46,47]. The food activity of fish is concentrated in the upper layers during the day when there is enough light [48]; therefore, the cladoceran communities can maintain their population by moving to the bottom layer to avoid predation [49].…”

As cladocerans are a primary food source for fish, predator avoidance is important to sustain cladoceran populations. We hypothesized that Bosmina longirostris and Daphniaobtusa would show different vertical distributions that depend on environmental variables and their life cycle phase. Quarterly monitoring was implemented in three water column layers (upper, middle, and bottom) in the Nakdong River Estuary. Cladocerans were mostly observed during summer; B. longirostris and D.obtusa were most abundant and exhibited different vertical distributions. Large (>600 μm) D.obtusa individuals were mainly distributed in the bottom layer (9–11 m) during the daytime and in the upper layer (1–3 m) at night. Utilization of the bottom layer by large D. obtusa was possibly a defense strategy to avoid fish predation. Although the bottom layer was not supported by lower water temperatures and dissolved oxygen than the upper or middle layers, as suggested in the previous study, we assumed that high turbidity replaced this role as a place shunned by fish (and thus a refuge for Daphnia obtusa). In contrast, smaller individuals remained in the upper layer at all times because of the low predation risk. The consumption of B. longirostris by fish was low, as the largest B. longirostris (411 μm) was smaller than the small-sized Daphnia. From this finding, we suggest that the vertical distribution of cladocerans likely depends on selectivity feeding based on fish size rather than the presence/absence of fish. We considered that these results are an important advance in understanding distribution patterns of cladocerans related to environmental features, as well as their key predators.

Zooplankton are the heterotroph aquatic organisms and has a week swimming. Zooplankton acts as the first consumer in the waters, which utilize phytoplankton as their food. This research located in Telaga Tunjung reservoir, Timpag Village, Kerambitan Subdistrict, Tabanan Regency. The reservoir is used for industry, irrigation and tourism development. The aim of the research was to determine the community structure of zooplankton in Telaga Tunjung reservoir. This research was conducted from January to February 2016. Water sampling was conducted twice with a sampling interval of 2 weeks in 4 stations. There was a total of 23 species of zooplankton found, consisting of 6 classes: Eurotatoria (8 genera), Ciliatea (1 genera), Branchiopoda (4 genera), Monogononta (1 genera), Tubulinea (1 genera) and Maxillopoda (3 genera). The most common species of zooplankton found in the sampling station were Polyarthra vulgaris (3.04 ind/l), Anuraeopsis coelata (1.28 ind/l), Keratella valga (0.43 ind/l), Vorticella sp. (0.49 ind/l), Diaphanosoma brachyurum (0.28 ind/l), Nauplius sp. (0.16 ind/l) and Megacyclops viridis (1.16 ind/l). The average abundance of zooplankton was 9.38 ind/l. Based on the abundance of zooplankton, the trophic status of Telaga Tunjung reservoir is mesotrophic.
