How do fish stay warm in the winter time outdoors?

Answer 1

Fish are Cold-blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warm-blooded animals. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal

Answer 2

Fish don't need to keep warm during winter, but they do need to avoid becoming frozen. Fish deal with freezing temperatures in two ways: some fish contain a protein antifreeze in their blood, but most fish take refuge in locations where the water doesn't freeze. In places like the Arctic Ocean, the seawater is below freezing and there isn't anywhere fish can go to find warmer water, so they produce a glycoprotein that does not freeze. In freshwater environments, waters don't usually freeze at the bottom of lakes, or in rivers where there is groundwater seepage into the water column, so fish seek these types of places during winter.

Answer 3

Fish don't need warmth; they need food and oxygen. As long as they are not literally frozen solid, they will survive. Sunlight shines through the ice and shines on the underwater plants, which are both an oxygen source for the fish and a food source for underwater insects (that also survive the super cold temps) which are in turn eaten by the fish. As long as there is a balance of sunlight, plants, and insects then all will be well when the ice melts. Blessings!!

Cassie, I'm not sure what you are calling the foam barriers? I assume you mean the air chutes that keep the insulation from blocking of the soffit ventilation. The attic itself needs to be properly ventilated to let moisture escape. Make sure you have proper soffit and ridge ventilation. The amount of ventilation required per code is increased if the ceiling does not have a vapor barrier installed. The vapor barrier should be on the warm side of the ceiling if you live in a cold climate.

Answer 5

They do not hibernate, although their activity is diminished. They dive down to waters that do not freeze. They are cold blooded. Water at the bottom of a lake is 4 degrees Celcius . It freezes at 0. Water is at its densest at 4 C so it sinks.

Answer 6

Fish are coldblooded and do not have to stay warm as we do.

Answer 7

fish go in the mud and thier body slows down in the winter months

Answer 8

they don't their metabolism slows way down. I don't think any fish truly hibernates.

Answer 9

they hybernate in a aquatic manner
