Fish do shrink on ice. Research shows shrinkage can average 1/4 to 1/2 inch. The size decrease varies by species and time on ice. Proper storage methods, like keeping fish in ice, can help reduce shrinkage. In contrast, live wells often maintain fish size better than ice storage. Additionally, fish are composed mainly of water. … Read more
