The model results were compared with conditions in Lake Erie from the recent past to determine when and how often different fish species would be affected. Lake Erie hypoxia negatively affected habitat quality for all species, as related to lower dissolved oxygen and higher water temperatures, but to varying degrees.
Whether bottom hypoxia has long-lasting consequences for pelagic fish populations remains speculative for most ecosystems. We explored hypoxia’s influence on two pelagic zooplanktivores in Lake Erie that have different thermal preferences: cold-water rainbow smelt (Osmerus mordax) and warm-water emerald shiners (Notropis atherinoides). To assess acute effects, we combined predictive ...

egative efects on fish can be dificult to understand. The most significant way hypoxic zones afect fish is by d. creasing the amount and quality of habitat available. For habitat to be of good quality, it must m. et the oxygen and temperature requirements of a fish. The habitat must also provide a fish with enough light to detect prey and enough.
Hypolimnetic hypoxia has been hypothesized to influence the structure of central Lake Erie’s fish populations and fisheries by altering access to prey resources and physicochemical habitat, including optimal thermal habitat (e.g., cold water) and prey resources (e.g., benthic macroinvertebrates) (10, 57–59). Indeed, negative effects of hypoxia on the movement, foraging, and growth of ...
Oct 28, 2024 · At present, the level of nutrient inputs is beneficial to yellow perch and walleye but limiting bottom habitat for whitefish. Finding the right balance between fishery and water quality ...
May 7, 2016 · The effects of hypoxia on fish and other aquatic organisms have been well-studied, but most research examines the negative aspects of hypoxia development on habitats and the effect of severe ...
Oct 28, 2024 · Hypoxia is bad news for lake whitefish that prefer the cold bottom water of Lake Erie, said Stuart Ludsin, a professor in the Aquatic Ecology Laboratory at Ohio State University. But, while the cyanobacteria in algal blooms thrive in fertile, nutrient-rich waters, so too do the plankton that feed the lake’s larger fish.
