“…In the Malye Chany Lake-Kargat Estuary, R. rutilus fry mainly preyed on benthic chironomid larvae and chrysalids from dipterans, whereas detritus and algae were also important items in their diet. Carassius auratus gibelio are generalist feeders, incorporating a variety of plant, animal and detrital material into their diets (Penttinen & Holopainen, 1992). In this study, C. a. gibelio fry mainly consumed chironomid larvae and cladocerans, although the importance of cladocerans in the diet decreased at stages G 2 and G 3 in comparison with earlier stages, whereas that of detritus progressively increased, as described in juvenile and adult specimens (Penttinen & Holopainen, 1992).…”

Feeding habits of P. fluviatilis fry from the Malye Chany Lake-Kargat Estuary were similar to those reported in other limnetic environments at similar stages of development (Popova & Sytina, 1977;Guma'a, 1978;Whiteside et al, 1985).…”

Feeding habits and the activity of digestive enzymes (total alkaline proteases, α-amylase and lipase) from dace Leuciscus leuciscus, roach Rutilus rutilus, Prussian carp Carassius auratus gibelio, perch Perca fluviatilis and pikeperch Sander lucioperca fry were studied in the Malye Chany Lake-Kargat Estuary (western Siberia, Russia). The diet of fry from all studied species was mainly composed of chironomid larvae and zooplanktonic organisms (i.e. cladocera and copepoda), whereas carnivorous species such as P. fluviatilis and S. lucioperca also preyed on fry from other fishes while detritus and microalgae were also important in the diet of ommivorous species. When comparing diet similarity (Sørensen-Dice index, Q(S)) among fry at different stages of development, both omnivorous and carnivorous species showed a high level of similarity (0.67 < Q(S) < 0.89 and 0.73 < Q(S)< 0.89, respectively). Diet similarity values were in agreement with the overall digestive activity profile analysed by cluster analysis. Diet similarity suggested potential trophic competition when zooplanktonic and benthic prey began to decline towards autumn. The analysis of pancreatic digestive enzymes revealed a correlation among their activities and fry feeding habits with α-amylase:total proteases (A:P) values higher than 1 in omnivorous species and lower (A:P ≤ 1) in carnivorous species.

“…Our mesocosm facility was set-up in Lake Erken (59°51′N, 18°36′E) in Central Sweden, which is a meso-eutrophic lake with ambient concentrations of TP at On 4 July 2017, the mesocosms were filled with lake water and a sediment layer of about 10 cm sediment was collected from the profundal area of the lake, and added to each mesocosm. Crucian carp is an omnivorous fish species with a mixed diet of macroinvertebrates (especially Chironomidae) and zooplankton (Penttinen & Holopainen, 1992) and we aimed for a biomass that is within the range of naturally occurring carp biomass (Holopainen & Pitkänen, 1985). Recruitment of Chironomidae to the mesocosms was possible via the addition of the sediments or through oviposition from the populations occurring naturally in Lake Erken.…”

The emergence of fatty acids—Aquatic insects as vectors along a productivity gradient

et al. 2019

1. Aquatic and terrestrial ecosystems differ fundamentally in the abundance of longchained polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA; 20:5n-3), which are produced by aquatic algae, but only in low quantities by terrestrial plants. Aquatic insects, such as Chironomidae (non-biting midges) feed on algae during their larval stage, making them rich in EPA and therefore high-quality prey for insectivores after emergence. However, the magnitude of EPA subsidies from aquatic insects may be different among water bodies in response to abiotic (e.g. nutrient load) as well as biotic factors (e.g. food web structure).2. To test the predation effects of crucian carp (Carassius carassius), nutrient concentrations, and Chironomidae community composition on the fatty acid export from aquatic ecosystems, we conducted a 25-day experiment across 20 1,500-L mesocosms covering a total phosphorus (TP) gradient of 20-1,000 µg/L.3. Twice a week, we collected adult emerging Chironomidae and found differences in fatty acid composition in the two most abundant chironomid species emerging from the mesocosms. Two PUFAs, α-linolenic acid and EPA, contributed to most of the variation in Chironomidae fatty acid content across the nutrient gradient.Whereas the proportions of α-linolenic acid were positively correlated to the mesocosm TP concentration, we found a negative correlation for the proportions of Chironomidae EPA and mesocosm TP concentration. However, despite lower biomass-specific EPA content at higher TP, higher biomass of emerging Chironomidae at intermediate TP concentrations resulted in higher total export of PUFAs from water to land. 4. Predation pressure from carp decreased the biomass of emerging Chironomidae on average 8-fold. Chironomidae biomass showed a hump-shaped relationship along the TP-gradient and was strongly influenced by periphyton biomass. 5. Export rates of EPA and fatty acids in general responded in a quadratic manner along the nutrient gradient, reaching a maximum value at a TP of 400 µg/L and decreasing thereafter.

“…In many lake ecosystems, chironomid larvae play an important role as prey for cyprinid fishes, including Carassius (e.g. Penttinen and Holopainen 1992;Specziár et al 1997;Jones and Waldron 2003). However, at our study site, chironomid larvae constitute only a small dietary fraction because they exhibited distinctively low δ 15 N values relative to those of fish muscle.…”

Although omnivorous cyprinid fish often dominate fish communities in shallow eutrophic lakes, their role in the food web is poorly known. In the present study, carbon sources of six cyprinid species were examined in a littoral freshwater habitat in a saline lake complex (Lake Chany, western Siberia, Russia) using stable isotope analyses (SIA). In this habitat, microalgae (phytoplankton and epiphytes), macrophytes and riparian vegetation comprised the major producer groups with distinctive δ 13 C values. Zooplankton and most benthic invertebrates functioned primarily as microalgae-based consumers, whereas the amphipod Gammarus lacustris depended largely on macrophytes or macrophyte-derived detritus. Cyprinids, Carassius carassius L., Car. auratus gibelio Bloch. and Abramis brama L., mainly utilised microalgae-derived carbon (δ 13 C-based isotope mixing model: 66-97%) via zooplanktonic trophic mediations. In contrast, Cyprinus carpio L., Leuciscus idus L. and Rutilus rutilus L. depended more on macrophytic and/or riparian production (52-80%) than on microalgal production. Observations and SIA of foregut contents indicated highly opportunistic feeding habits of R. rutilus and L. idus and preference for macrophytes. These results suggested that cyprinid fishes link pelagic, benthic and riparian food webs in this shallow, eutrophic lake ecosystem.Additional keywords: δ 13 C and δ 15 N, food sources, isotopic mixing model, macrophytes, omnivorous fish, phytoplankton.
