Summary

Gape and heave of fish are usually caused by the internal pressure during comparatively low temperature calcium chloride brine immersion-spray freezing of a round type or a semidressed type tuna. Thermal equalize freezing is a method of freezing to prevent these defects; it is done in 3 steps: freezing, thermal equalizing and second freezing. The freezing times are the sums of these three steps: 10.1 hours for yellow-fin tuna, 13.7 hours for big-eye tuna. No gape was found.
