How does temperature affect goldfish respiration rate?

I found that when fish are put in warmer water their breathing speeds up and when fish are put in cooler water their breathing slows down. The average breaths for 50 degrees is 82, the average for 60 degrees is 90 breaths per minute and the average for 70 degrees is 110 breaths per minute.

What is the dependent variable in the goldfish experiment?

The dependent variable in the lab is the growth or length of the fish. 12. Identify the control in the lab. The control in the lab is the goldfish that were fed regular fish food.

How does light affect fish respiration?

Light conditions significantly increased euphausiid respiration. These two factors provide insight into the metabolic effects of diel migration and changing ocean temperatures. Additionally, the zooplankton follows the trend of larger size having a lower metabolic rate.

Will the temperature of water affect how much goldfish will eat control?

Instead, they rely on the temperature of their environment to regulate their metabolisms and activity levels. When it’s too cold, they’re less active, their appetite is reduced and their immune systems are compromised, making them more susceptible to disease.

Why do goldfish breathe slower in cold water?

the rate of respiration decreases in cold water—even though the water may contain higher concentrations of dissolved oxygen. This is because fish require less oxygen as their metabolism slows in cold water and as a result, they don’t need to work as hard to pass water over their gills to get the oxygen they need.

Why do goldfish breathe more in hot water?

You can see how fast a fish is breathing by watching the gill cover(operculum) move. You will see that they breathe faster in warm water. One reason is that warm water holds less oxygen. Another is that the warmer water will speed up the metabolism of the fish, which means they need more oxygen.

How does water temperature affect goldfish?

As water temperature moves from the 50s to the 70s, the speed of digestion increases, the rate of oxygen consumption goes up, and the immune response quickens. Goldfish in aquariums kept at 75 degrees will probably eat five to 10 times more fish food per month than goldfish kept at 58 degrees.

What is the factor being tested or changed on purpose?

The part that is changed on purpose is called the independent variable.

What happens to fish respiration if the temperature of the water is too high or too low?

However, as water temperature rises, the oxygen in the water is decreased. This makes warmer water less habitable for fish. If the temperature reaches critical levels, the fish can no longer breathe.

How hot is too hot for goldfish?

What water temp is too hot for goldfish? Your goldfish will become very stressed if kept in water that is warmer than 27°C / 80°F. What is this? Avoid placing your tank in direct sunlight or near radiators so that your water temperature stays below this level.

Can goldfish live in heated water?

Basically, goldfish can survive in a wide range of temperatures. They can thrive in a heated tank as they can do in normal room temperatures. However, for fancy goldfish the water should not be heated over 75 degrees F. this is because they thrive in temperatures between 60-72 degrees F.

Do fish like hot water?

Warm Water Important for Cold-water Fish Like Salmon and Trout, Study Finds. Cold-water fish need both warm and cold water habitats at different parts of their life cycle. Warm river habitats appear to play a larger-than-expected role in supporting the survival of cold-water fish, such as salmon and trout.

How many times does a goldfish breathe in 1 minute?

The average respiration rate for all six control goldfish ranged from 120 to 99 breaths per minute (not a significant change). The average results for all groups that experimented using a control fish showed that water temperature did promote changes in the goldfish‟s respiration rate.

What is the pH level for goldfish?

between 7.0 and 8.4
Goldfish Water Requirements pH is not critical, but ideally should be between 7.0 and 8.4. Rapid changes in temperature or water chemistry can be harmful, if not fatal to goldfish. A tablespoon of aquarium or sea salt per 5 gallons can also be used to help keep goldfish in good health.

Do goldfish survive freezing?

Goldfish survive below-freezing temperatures by going into hibernation, but only if they receive plenty of oxygen. Keeping ice off part of your pond is crucial.

What is the summary at the end of an experiment that explains the results?

CONCLUSION. The final step in the scientific method is the conclusion. This is a summary of the experiment’s results, and how those results match up to your hypothesis.

What variable was purposely changed in the experiment?

Independent Variables (What is being tested) An independent variable is the variable that the experimenter purposely changes or manipulates. The independent variable is the cause, input, or what is being done during the experiment.

Can fish be too cold water?

In particular, the water temperature has a direct effect on your fish’s metabolism. If your tank temperature is too cold, then your fish’s metabolism will slow down, which leads to your fish becoming sluggish and sleepy. On the flipside, water that is too warm causes your fish’s metabolism to speed up.
