   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.

These low oxygen areas are often referred to as “dead zones,” because many mobile organisms leave the hypoxic zone, a. d many sessile organisms die without adequate oxygen. Fish are forced to leave the cooler, deeper waters to inhabit new areas with more oxygen, but p.

   Utilization of the bloom by prey-fishes led to high levels of microcystin toxin accumulation, offering a potential mechanism for transfer of microcystins up the food web to economically important sportfishes in Lake Erie (e.g. walleye and yellow perch).

   In recent findings, researchers at Purdue University used bioenergetic growth rate models, which use data about conditions that each species needs in order to survive, to determine when and at what depth fish species' habitats were affected by hypoxia.

   Oct 28, 2024 · Hypoxia is bad news for lake whitefish that prefer the cold bottom water of Lake Erie. 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. And not all of those fish live at depths where hypoxia is a problem.

   Does hypoxia affect mobile fish species in Lake Erie?

   • Additionally, the growth and survival rates of some preferred benthic prey (e.g., Chironomidae) are largely unaffected by low DO conditions ( Armitage et al., 1995 ). Potential in situ impacts of hypoxia on mobile fish species in Lake Erie appear to be indirect and vary among species.

   Why did the ecofore-Lake Erie project focus on CB hypoxia?

   • The EcoFore-Lake Erie project focused on CB hypoxia because of uncertainty about the mechanisms underlying its return to levels commensurate with the height of eutrophication during the mid-20th century ( Hawley et al., 2006) and because of its great potential to harm Lake Erie's valued fisheries (sensu Ludsin et al., 2001 ).

   Are anthropogenic stressors affecting Lake Erie?

   • Reductions to these levels are also protective of fish habitat. Several anthropogenic stressors have impacted Lake Erie since European settlement. However, phosphorus (P) loading has been particularly influential ( Ludsin et al., 2001 ).

   How does hypoxia affect fish growth?

   • Several ecological processes that are influenced by hypoxia have the potential to negatively affect individual fish growth, survival, reproductive success and, ultimately, population growth (e.g., Breitburg, 2002, Coutant, 1985, Ludsin et al., 2009, Wu, 2009 ).

   Can wind-driven mass movement of hypoxic water cause fish deaths?

   • In fact, there is recent evidence of such events in nearshore Lake Erie, whereby wind-driven mass movement of hypoxic waters into nearshore zones appears to have led to localized fish mortalities (J. Casselman, Queen's University personal communication).
