Causes

Effects

Damagecausedto fish by too much dissolved oxygen in water

Rainy conditionscan causeoxygen problems ( for fish

organic matterresultingin a low dissolved oxygen environment for the fish

The late wintercausedoxygen stress on the fish

chokes out aquatic vegetationresultingin lower dissolved oxygen necessary for fish to survive

to decomposeresultingin a low - dissolved - oxygen ( DO ) fish kill

the harmful substances they produceleadsto lower oxygen for fish

that untreated waste water and industrial effluents had been discharged upstreamresultingin fish dying of oxygen depletion

These conditionscan causedissolved oxygen levels in the water

that the deaths may be caused by the high salinity concentration and the high temperature of the sea water during the extreme low tidesresultingin less oxygen for the fish

the level of replacement and consumption(passive) is influenced byThe amount of dissolved oxygen in the water

warm watercan ... causefish to need more dissolved oxygen

excessive phytoplankton bloomscould leadto dissolved oxygen depletions ... resulting in fish kills

The presence of the organismscan causea depletion of dissolved oxygen in the water

the processesleadto oxygenation and de - oxygenation in the aquarium - " Aeration and dissolved oxygen

the surface of a pondwill causedissolved oxygen depletions and fish kills

Nitrogen and _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _can contributeto low levels of dissolved oxygen ( fish kills

Avoidoverdose : although this does not have toxic effects , might promote excessive bacterial growthcausinga decrease in dissolved oxygen in the aquarium
