Prevent Fish Kills in Lakes and Ponds
Unfortunately, as water warms, the cold-blooded fish become more active and require more oxygen. Larger fish of any species are usually the first to die when oxygen concentrations become too low. Desirable fish species, such as grass carp, bass, channel catfish and bluegill, are more susceptible to low oxygen levels than bullheads, carp ...

An Introduction to Eutrophication in the UK
Large fluctuations in dissolved oxygen concentrations can occur between day and night. Low oxygen levels, the result of plant respiration, may lead to the death ... fish. This process can be compounded when algal blooms, through their decay, further reduce the oxygen content of water. The growth or decay of benthic (bottom-dwelling) mats of macro- ...
