Water-Thawing of Frozen Cod Blocks
Thawing time for frozen blocks of dressed cod (Gadus morhua) was investigated. Observations were made on the effect of size of individual fish, water recirculation rates, water temperature, block height, thickness and orientation, separation of individuals from the block at some intermediate time, a...
