Below is the general result of an experiment done on Emerald Shiners in relation to Lake Erie. Remember this is one experiment, so the results shouldn't be taken as proof positive, just a probable effect of the recent larger algae blooms. The experiment was done in 2018.

Undergraduate Honors Thesis by Harrison S. Fried

"Since survival is directly affected by Ucrit and aerobic capacity (Brett 1964), the results of
this study suggest possible deleterious effects of turbidity on fitness. Emerald Shiner exhibited
significantly lower swimming performance in algal turbidity compared to clear-water. Such a
decrease in swimming ability suggests that algal turbidity particles had a negative impact on
Emerald Shiner. One possibility is that mucous build-up on the gills in response to algal particles
inhibited aerobic respiration

My study suggests that algal turbidity has strong effects on the swimming ability of
Emerald Shiner, filling in a previous gap in knowledge on the effects of turbidity on Emerald
Shiner swimming performance. In fact, a significant decline in swimming ability from clear to
algal conditions, as shown by my study, may insinuate a bleak prognosis for the Emerald Shiner
in Lake Erie. As algal blooms in the western basin of Lake Erie recur each year (Steffen et al.,
2014), Emerald Shiners will repeatedly experience conditions detrimental to survival and
physiological fitness. "
