Is too much oxygen bad for fish

Answered By: Timothy Morgan Date: created: Nov 21 2022

Too much oxygen in water can lead to the potentially lethal gas bubble disease, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes.

(Excess nitrogen, however, is a far more common cause of this disease.).

Does boiled water contain oxygen

Answered By: Herbert Foster Date: created: Sep 26 2022

As you can see in the oxygen solubility in water curve below, water looses oxygen in small amounts as you raise the temperature. At 40°C (104ºF) the presence of oxygen dissolved in the water is already so low that there is almost no difference between oxygen levels at that temperature and at the boiling point.

Is water a oxygen

Answered By: Norman Hernandez Date: created: Nov 13 2021

Although water molecules contain an oxygen atom, this oxygen is not what is needed by aquatic organisms living in natural waters. A small amount of oxygen, up to about ten molecules of oxygen per million of water, is actually dissolved in water.

Asked By: Gregory Rodriguez Date: created: Dec 04 2021

What is the minimum dissolved oxygen required for aquatic life

Answered By: Leonars Washington Date: created: Dec 05 2021

The generally accepted minimum amount of DO that will support a large population of various fishes is from 4 to 5 mg/l. When the DO drops below 3 mg/l, even the hardy fish die.

How can water be more than 100% saturated

Answered By: Horace Simmons Date: created: Aug 24 2022

Dissolved oxygen readings of greater than 100% air saturation can occur in environmental water because of the production of pure oxygen by photosynthetically-active organisms and/or because of non-ideal equilibration of dissolved oxygen between the water and the air above it.

Asked By: Jordan Russell Date: created: May 22 2022

How much oxygen is in the water

Answered By: Oswald Griffin Date: created: May 24 2022

Oxygen concentrations are much higher in air, which is about 21% oxygen, than in water, which is a tiny fraction of 1 percent oxygen. Where the air and water meet, this tremendous difference in concentration causes oxygen molecules in the air to dissolve into the water.

Asked By: Isaiah Lewis Date: created: Dec 18 2021

How much dissolved oxygen do fish need in ppm

Answered By: Lucas Bennett Date: created: Dec 18 2021

Fish growth and activity usually require 5-6 ppm of dissolved oxygen. Dissolved oxygen levels below 3 ppm are stressful to most aquatic organisms. Levels below 2 ppm will not support fish at all.

Asked By: Jordan Torres Date: created: Feb 27 2022

How do you calculate oxygen saturation in water

Answered By: Brandon Martin Date: created: Feb 27 2022

Example: Determine the % saturation of dissolved oxygen in a stream given the following information: Temperature (13 C); DO (7.6 mg/L). Using the monogram above your answer would be about 72 – 75 depending on your line. Another method is to divide 7.6 by 10.6, which is the 100% solubility at 13 C, then multiply by 100.

Asked By: Fred Long Date: created: Apr 27 2022

Do fish breathe in oxygen

Answered By: Gavin Rivera Date: created: Apr 27 2022

Fish breathe with their gills, and they need a constant supply of oxygen. Gills sit under the operculum.

Asked By: Cody Bryant Date: created: Feb 28 2022

How fast does oxygen dissolve in water

Answered By: Angel James Date: created: Mar 01 2022

Oxygen is absorbed in water by direct diffusion and by surface-water agitation. Solubility of oxygen in water is so small and by diffusion process alone in still water, it was culculated that it would take 6 years for oxygen to diffuse from surface to a depth of 6 meters in quiet water.

Asked By: Julian James Date: created: Sep 24 2022

What is the maximum dissolved oxygen in water

Answered By: Lewis Lewis Date: created: Sep 26 2022

While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these factors interact.

Asked By: Howard Cox Date: created: Oct 12 2022

What is the formula for dissolved oxygen

Answered By: Kevin Richardson Date: created: Oct 13 2022

Remember that in 200 mL sample, 1 mL of sodium thiosulfate of 0.025N equals to 1 mg/L dissolved oxygen: =>Dissolved oxygen (DO) (in mg/L) = mL of sodium thiosulfate (0.025N) consumed.

Asked By: Brandon Jackson Date: created: Mar 21 2022

What happens if dissolved oxygen is too high

Answered By: Alan Davis Date: created: Mar 24 2022

Too much dissolved oxygen is not healthy, either. Extremely high levels of dissolved oxygen usually result from photosynthesis by a large amount of plants. Great uncontrolled plant growth, especially algal blooms, is often the result of fertilizer runoff. This phenomenon is called cultural eutrophication.

Asked By: Dennis Walker Date: created: Jan 13 2022

Can humans get oxygen from water

Answered By: Daniel Nelson Date: created: Jan 16 2022

Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don’t breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.

Asked By: Brian Butler Date: created: Aug 15 2021

What happens if oxygen is removed from water

Answered By: Anthony Garcia Date: created: Aug 18 2021

Water is one third oxygen; without it, the hydrogen turns into gaseous state and expands in volume. The oceans would evaporate and bleed into space. As oxygen disappears from the oceans’ water, the hydrogen component becomes an unbound free gas.
