ALIVE IN ICE

I FROZEN FISH WHICH THAW j AND SWIM. I The director of a new Chicago aquarium is investigating t the possibilities, says Reutcr, of importing live Alaskan blackfish in blocks of ice with the idea of thawing them out for • exhibition in the show tanks. Such a scheme has already been considered by the aquarium authorities at the London Zoo, for there arc many fish which will stand being frozen solid and still revive when carefully restored to normal conditions. At the temperature of freezing water these fish go to sleep. An Ordinary goldfish which jumped out of its tank lay for IS hours on \ a conservatory floor dried up like a bloater, yet came to life when restored to the aquarium. It was freezing hard at the time and this fact saved its life; in warm weather it would have gasped out its life in a few minutes instead of becoming comatose. In Siberia, -where the streams freeze solid, fish are actually quarried out for market. They are sold in the crystal casings, and cbme to life in the kitchen only to die in the frying-pan. A pet trout in a Cumberland household was frozen solid during one winter and could be seen for some time in the middle of a block of ice. The thaw cume and it once more swam about. In the process which is' being considered in the Chicago case mentioned above the fish are slowly chilled in tanks until they become sleepy. Then, in highly aerated water, they are slipped inside a hollow in a. block of ice and frozen stiff. There they sleep until scientifically thawed.
