I am doing a science fair on fish and i have a question....?

Question

My project will be = Does the temperature affect the respiration rate of a fish?

I ned to use a fish with a wide range of tempertaure like a fish that can be 75-85 degrees. Please help suggest a fish.

I need some info on that topic! Thanks!

Answer 1

do it with a crayfish. they are interesting easy to keep and eat pretty much everything. just feed them pellets and other random stuff like shelled peas. it would be interesting because you could see something about their shells, or if they hibernate. hope I helped

Answer 2

A goldfish or a cat fish would be the best fish for you to use.  While colder water holds more oxygen and warmer water less, the respitory rate in short is affected.  The warmer the water and less oxygen the harder the fish has to work to remove what dissolved oxygen is in the water.

Goldfish can go from freezing cold water to 90's (the later not for long periods of time).  In the colder water respiratory rates slow to a hybernation state (under 50)

However temperature is not the only thing that taxes a fish's respiration.  Toxins in the water do as well.  It all boils down to oxygen levels.

Temperatures also affect the "body" of fish.  The colder the body the more dense the fish, the warmer the water the softer the body of the fish is.

Answer 3

Betta fish can handle those temperatures, but I'd hope you aren't trying to torture the little guy by buying a bunch in little bowls, heating there temperatures at random and then just leaving them ignored and to die.

Answer 4

Instead of using a live fish for this experiment, create a 3-D image of a fish in a bowl, and use this as your presentation. Young kids should know how to do this if they pay attention in school.....research on the web on how to do this. It would be cruel to the fish to experiment on it...

Answer 5

the most durable fish that i would go with are either a goldfish cuz they can take temps from 68- 82 degrees F. Maybe a betta cuz they are extremly durable as well. Anyhting other than that I would avoid cuz they are way too sensitive. By the way the experiment may kill the fish. It may get ich which is a fish desease that looks like they have salt grains stuck to their body and then they die.

Answer 6

Bettas can do ok at those temps for a short period of time, but I would change your project to a certain type of fish, b/c thet varieys between fish. Once yuo are done with your betta, make sure you acclimate him to the new temps and keep his normaltank at 80F.

NO GOLDFISH! They die at high temps and need HUGE tanks!
