Ponds and lakes freeze from the top down, meaning that beneath the icy surface there is usually a layer of liquid water where fish swim. But what about fish that are caught in the ice? It stands to reason that the extreme cold would damage the fishâs tissue, effectively killing it. 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.
