Why does frozen fish shrink?
Fish is about 70 percent water, and the longer it takes for that water to freeze, the larger the ice crystals become, eventually piercing and bursting cells in the flesh. When slowly frozen fish is thawed and cooked, the cell damage may cause moisture loss, shrinkage, and dryness in the flesh.
Why do fish shrink?
In the coming decades, warming ocean temperatures could stunt the growth of fish by as much as 30 percent, according to a new study in the journal Global Change Biology. The main driver behind this decline in size is that warmer water contains less oxygen.
