Summary

GOLDFISH SKELETAL MUSCLE WAS EXAMINED WITH THE ELECTRON MICROSCOPE TO INVESTIGATE THE ULTRASTRUCTURAL CHANGES PRODUCED BY FREEZING. AQUARIUM FISH WERE USED TO CIRCUMVENT THE VARIABLES ASSOCIATED WITH CATCHING AND KILLING LARGE FOOD FISH. THE RESULTS CONFIRM THE CONCLUSIONS IN THE LITERATURE THAT FAST FREEZING (IN LIQUID NITROGEN) PRODUCES MANY SMALL ICE CRYSTALS WHICH CAUSE MINIMUM DISLOCATION OF TISSUE ULTRASTRUCTURAL COMPONENTS, WHEREAS SLOW FREEZING GENERATES FEWER LARGE ICE CRYSTALS WHICH DISTORT CELLS AND CRUSH MYOFIBRILS.
