if it is a cosmetic pond put your fish in an aquarium and drain your pump so it doesn't freeze and break drain your pond
Yes
Lake freezes first at the surface is convection involved
It explodes and the apocalypse happens.... What do you think happens? it freezes
It freezes.
If the water freezes but the pond is deep enough for the fish to still be in water at the bottom there is a good chance they will survive. If all of the water freezes however and the fish become frozen solid then I'm afraid they are unlikely to survive.
You must drain the lake and find the fish before they drown.
It freezes
It has to do with their blood. The same happens with humans. When fish blood freezes it crystallizes, like water. When this happens the crystals can damage the tissue of the fishes vital organs. Making it impossible to revive them after they have been cryo-preserved.
You dry dock it.
Fish go further down than the ice. The ice usually doesn't freeze all the way to the bottom. If the fish are trapped in shallow water or if the lake or stream freezes to the bottom, they will freeze.
As water freezes, it expands, becoming less dense. This means that the ice is on the TOP of the lake, and the fish are below the ice, in unfrozen water. If it were not for this property of water, lakes would freeze from the bottom up, killing the fish. Most things do NOT expand when they freeze.
Lake Erie is the lake with the highest fish population
