Question

Do fish survive the winter if they've become completely frozen in solid ice?

Answer 1

Not the freshwater fish of North America.  But that would not happen anyway.  The ice never forms top to bottom, only on the surface.  So that usually leaves lots of free water in which the fish can survive in.

A fish metabolism is regulated by the temperature of the surrounding water.  So in winter, in ice covered lakes, the water temperature below the ice is just above freezing.  Warm enough to keep the water from freezing but cold enough to reduce the fish metabolism to almost nothing.  A fish usually makes it through winter on fat reserves.

whatch ice age 2... and you will get your answer...

Answer 3

It is true that some fish can spend the winter frozen in ice and come out swimming once the ice melts.

Like all cells, fish cells contain saline, or salt water. Since salt water has a lower freezing point than pure water, even when encased in ice at thirty-two degrees Fahrenheit, cold-water fish are not technically frozen. Moreover, some fish contain a kind of antifreeze substance that allows them to survive very cold conditions.

The Notothenioids are a group of more than 120 marine fish species, most of which are native to Antarctic waters. Antarctic Notothenioids have remarkable proteins in their bloodstream that prevent them from freezing. These "antifreeze proteins", as they are commonly known, bind to tiny ice crystals in their bodies, inhibiting further growth.

Answer 4

no..thats called a "freeze off"

if they freeze they die
