“…It therefore seems likely that Bythotrephes were having a strong direct effect on these overlapping epilimnetic-metalimnetic prey, as well as contributing indirectly to energetic costs to species like D. mendotae that vertically migrate into cool, suboptimal feeding habitats to avoid high concentrations of Bythotrephes (Pangle and Peacor, 2006). This study and the study of Makarewicz et al (1995), which examined August data from U.S. EPA summer cruises during 1983-1992, a period of highly variable abundance of forage fish and the initial invasion of Bythotrephes, both point to the potential importance of fishes and Bythotrephes as important controllers of zooplankton in Lake Michigan. In fact, Bythotrephes can be even more important controllers of zooplankton than fish because of Bythotrephes' high abundance and high weight-specific feeding rate relative to fish, as evidenced by a 2007 study in Lake Huron in 2007 .…”

“…In the past, knowledge of changes in Lake Michigan zooplankton in the offshore region came from two kinds of studies: (1) documentation of dramatic changes during summer in response to stressors such as non-indigenous species and weather (e.g., Lehman, 1991;Scavia et al, 1986;Wells, 1970) examined over a few years, or (2) long-term EPA surveys of offshore stations during early spring and late summer cruises (e.g., Barbiero et al, 2009a;Makarewicz et al, 1995). Both may miss important seasonal patterns, and the highly dynamic plankton succession may not be in any seasonal steady state during the surveys.…”

Fahnenstiel, Gary L.; Cavaletto, Joann F.; Liebig, James R.; Stow, Craig A.; Nalepa, Thomas F.; Madenjian, Charles P.; and Bunnell, David B., "Seasonal zooplankton dynamics in Lake Michigan: Disentangling impacts of resource limitation, ecosystem engineering, and predation during a critical ecosystem transition" (2012 We examined seasonal dynamics of zooplankton at an offshore station in Lake Michigan from 1994 to 2003 and 2007 to 2008. This period saw variable weather, declines in planktivorous fish abundance, the introduction and expansion of dreissenid mussels, and a slow decline in total phosphorus concentrations. After the major expansion of mussels into deep water (2007)(2008), chlorophyll in spring declined sharply, Secchi depth increased markedly in all seasons, and planktivorous fish biomass declined to record-low levels. Overlaying these dramatic ecosystem-level changes, the zooplankton community exhibited complex seasonal dynamics between 1994-2003 and 2007-2008. Phenology of the zooplankton maximum was affected by onset of thermal stratification, but there was no other discernable effect due to temperature. Interannual variability in zooplankton biomass during 1994 and 2003 was strongly driven by planktivorous fish abundance, particularly age-0 and age-1 alewives. In 2007-2008, there were large decreases in Diacyclops thomasi and Daphnia mendotae possibly caused by food limitation as well as increased predation and indirect negative effects from increases in Bythotrephes longimanus abundance and in foraging efficiency associated with increased light penetration. The Bythotrephes increase was likely driven in part by decreased predation from yearling and older alewife. While there was a major decrease in epilimnetic-metalimnetic herbivorous cladocerans in 2007-2008, there was an increase in large omnivorous and predacious calanoid copepods, especially those in the hypolimnion. Thus, changes to the zooplankton community are the result of cascading, synergistic interactions, including a shift from vertebrate to invertebrate planktivory and mussel ecosystem impacts on light climate and chlorophyll.

“…High dissolved oxygen concentrations in the spring correlated with low phytoplankton biovolume, which presumably resulted from low temperatures. Herbivory at this time of the year is thought to be negligible given typically low zooplankton biomass (Makarewicz et al, 1995), although we did not measure this in Mona Lake. Similar to other studies (Freedman et al, 1979;Huszar and Caraco, 1998), high total phosphorus concentrations and high temperatures correlated with the highest phytoplankton biovolumes, which were measured in the summer of 2003.…”

“…All prey were cultured in the laboratory, with the exception of H. gibberum, which was collected from Fletcher Lake every second day. H. gibberum was included in this experiment because there is some support that Bythotrephes may consume this jelly-clad cladoceran (Makarewicz et al 1995;Schulz and Yurista 1998;Wahlström and Westman 1999), although it is one of the species that thrives in the invaded lakes of our study region (Yan and Pawson 1997;Boudreau and Yan 2003). All prey provided were barren to the naked eye, and only mid-size B. freyii were selected on the assumption that they would not release neonates within 24 h. We elected not to starve Bythotrephes before experimentation, as this would likely result in overestimates of feeding rates.…”

The invasive spiny water flea's (Bythotrephes longimanus) current North American distribution encompasses the Laurentian Great Lakes as well as a number of inland lakes, particularly on the Canadian Shield. In the past, poor survival in the laboratory has precluded controlled long-term studies on Bythotrephes. Here we investigated field collection techniques and choices of culture media, temperature, and diet that led to the successful maintenance of Bythotrephes from birth to reproduction. Gravid parthenogenic females were collected from invaded lakes. Resulting offspring were reared in source lake water filtered through 20 or 80 µm, or a fully defined artificial culture medium, FLAMES. Individuals raised in FLAMES produced significantly larger broods than those in lake water, indicating that it is an appropriate culture medium. We next conducted a 96-h temperature bioassay on juvenile Bythotrephes. Survival was comparable at 16°C, 20°C, and 24°C but decreased after 48 h at 28°C, and most animals died after 24 h at 32°C. We also reared Bythotrephes at 16°C, 19°C, 22°C, and 25°C. Corresponding intrinsic rates of natural increase (r) for animals maintained to first brood release were 0.02, 0.05, 0.06, and 0.03 d -1 , suggesting that Bythotrephes should be reared at ~22°C to benefit from maximum population increases. Feeding trials confirmed that young Bythotrephes prefer small, slow-moving prey. Finally, we devised a protocol for rearing Bythotrephes that yielded 100% survival to reproduction and r = 0.10 d -1 (for animals maintained to first brood release). Given these results, it is now possible to conduct long-term laboratory studies on this invader.
