Does water temperature effects the movement of goldfish hypothesis?

Answer 1

Goldfish are cold blooded creatures. The speed of their metabolism depends upon the temperature of the water they are in. They are essentially Carp and so they have evolved to perform and do best in temperate conditions. Their best temperature range is from around 50F up to 70F. At 70F their metabolism is going full pelt and this is the temperature they breed at. Any warmer than around 73F and they can suffer burn out and shortage of breath because their gills are not efficient enough to collect sufficient oxygen from the oxygen depeted warm water. Below 50F their internal organs begin to slow down as the fish too slows down. They eat less and do less until the water gets cold enough for them to stop doing anything . They can then survive just above freezing (32F) by going into a kind of trance 'hibernation'.

Answer 2

The warmer the water the faster the metabolism. Beyond a certain point the fish can no longer breathe because the higher metabolic rate demands for Oxygen exceeds the fishes capacity/ability to gain sufficient Oxygen from the depleted warmer water and the fish dies from asphyxiation. As the water gets cooler the opposite occurs and the fishes metabolism slows down. As the temperature approaches freezing the fish comes to a standstill. The fish no longer moves and its breathing is reduced to an absolute minimum. Any colder and the fish will not have the energy (heat) to enable it to breath and it will die.

Answer 3

I am doing my science fair project on this. I have tested some and since goldfish are cold blooded, the warm water has been effectign them the most.

Answer 4

Goldfish being coldblooded creatures react to cold the same way most other creatures do. The colder it gets the slower the movement and the metabolism.

Answer 5

Over 70F goldfish start to breath a bit heavily. Over 80F they are in major trouble. They are cold water fish and should be kept below 70F and above 50F if possible.
