“…Phytoplankton sedimenting onto a reservoir bottom is a favorite food for Chironomus. The diatoms that, in spring, constitute a major proportion of the phytoplankton in rivers feeding Zegrzyński Reservoir (Bubień 1989) exhibit a very high nutritive value, because of high concentrations of unsaturated fatty acids (Johannson and Beaver 1983, Rasmussen 1984, Goedkoop and Johnson 1996, Ahlgren et al 1997, Goedkoop et al 2000. A continuous supply of sedimenting tripton, rich in diatoms, is probably the main cause of the high numbers of Chironomus observed during the spring peak.…”

Chironomus f. l. plumosus larvae, a valuable food of bream (Abramis brama (L.)), dominate in the benthos of the extra-littoral zone of the shallow, lowland, eutrophic Zegrzyński Reservoir. Bream is the dominant fish species in this reservoir, making up to 80% of total net catches. During eight years of studies, very regular Chironomus population dynamics were noted in the lotic part of the central, broad basin of the reservoir. There were usually two peaks of the abundance: the higher one in spring, and the much lower one in late summer. reservoir in particular years. The total bream catch per year in the reservoir studied also correlated positively with the average yearly abundance of Chironomus. The correlation between Chironomus abundance and bream occurrence (measured by commercial net catches) in the reservoir studied suggests that this environment is used by bream mainly as a feeding ground. In the years with a low spring Chironomus peak of abundance, the bream leave the reservoir, searching for food in its inflows -two large, lowland rivers. This corresponds to much lower catches noted in the reservoir in the years of low Chironomus abundance.

“…Similarly to Lake Balaton, contemporary winter cohorts were found in Procladius spp. in Lake Erken (Goedkoop & Johnson 1996). (7) In T. punctipennis two generations per year with two parallel winter cohorts were found in the Neusiedler See (Wolfram 1996), two to three generations in Lake Banyoles (Prat & Rieradevall 1995) and one to two in Essendon ponds (Learner & Potter 1974).…”

Life history patterns of the three most abundant chironomids were analysed in Lake Balaton by monitoring the population dynamics of larvae and the presence of pupal exuviae. Procladius choreus had two generations per year with at least two parallel cohorts during 1996-1999. Tanypus punctipennis had a trivoltine life cycle with occasional parallel cohorts, overlapping generations and long, interrupted emergence periods between 1997 and 1999. At Tihany, Chironomus balatonicus had only one detectable generation between 1995 and 2002. Meanwhile at Keszthely, the abundance of C. balatonicus larvae peaked from autumn to the beginning of summer in

“…However, benthic and pelagic energy flows and processes can be coupled in a variety of ways (Goedkoop and Johnson 1996, Schindler and Scheuerell 2002, Vander Zanden et al 2006. Fish often play an important role in combining benthic and pelagic food webs due to their high mobility and flexible foraging tactics that lead to inter-habitat omnivory (Diehl 1995, Jeppesen et al 1997, Post et al 2000.…”

“…A possible explanation is that profundal zoobenthos and zooplankton have a unique d 13 C value that reflect their diet of settling phytoplankton, though they can not easily be differentiated using d 15 N (Vander Zanden et al 2006). However, under oxic conditions, sedimented organic matter produced in surface habitats and allochthonous organic inputs also allow the consistent development and high productivity of benthos in the profundal region (Lindegaard 1994, Goedkoop and Johnson 1996, Vander Zanden et al 2006. The energetic link of pelagic fish with the profundal food web may be important to the maintenance of pelagic trophic cascades, especially in deep lakes, because profundal prey provides pelagic predators with an additional energy source (Polis et al 1997, Vander Zanden and.…”

Benthic–pelagic coupling in lake ecosystems: the key role of chironomid pupae as prey of pelagic fish

Citation: Wagner, A., S. Volkmann, and P. M. A. Dettinger-Klemm. 2012. Benthic-pelagic coupling in lake ecosystems: the key role of chironomid pupae as prey of pelagic fish. Ecosphere 3(2):14. http://dx.doi.org/10.1890/ES11-00181.1Abstract. Studies of lake ecosystems have often treated benthic and pelagic habitats as discrete food chains with parallel, separated compartments. A limited number of studies on the importance of fish feeding for benthic-pelagic coupling have been conducted with a food-web perspective of lakes. We hypothesize that pelagic fish couple benthic and pelagic food webs by feeding on chironomid pupae ascending from the sediment to the surface. Over a two-year period, an analysis of the stomach contents of Eurasian perch (Perca fluviatilis L.) was combined with simultaneous catches of chironomids in near-bottom pupal traps and floating emergence traps exposed in the littoral and profundal region of a deep temperate reservoir. Chironomid larvae rarely served as prey for perch. While chironomid pupae from the littoral region were of minor importance as perch prey, we determined a substantial vertical trophic biomass transfer from the profundal to the pelagic food web for the pupation peak of profundal chironomids from May through June. During this period, chironomid pupae represented approximately 20-48% of the ingested biomass of all size classes of perch (70-340 mm). The pupae of only three large profundal species out of 84 chironomid taxa detected in the reservoir represented approximately 80% of the chironomids consumed by perch, indicating a key role for these taxa in benthic-pelagic coupling. The strong influences of species, habitat and size on the consumption of chironomid pupae by the pelagic perch provide the importance of detecting key benthic species that substantially contribute to the pelagic food web. The phenology of profundal species results in a seasonal shift in the feeding behavior of pelagic fish, which thereby influences the trophic dynamics of lake ecosystems. Therefore, we argue for a more integrated view of lake ecosystems that recognizes not only the littoral but also the complementarity of profundal and pelagic production pathways crucial for ecosystem functioning.
