What It Means When You See Gaps In The Flesh Of The Fish You're Buying
Gaps in the flesh of store-bought fish, often seen as splits or pits in the muscle fibers, are a telltale sign that the fish was not handled with care.
Fish flesh is delicate, and rough handling during catching, processing, or transportation can cause the muscles to tear apart, creating these gaps.
When cooked, fish with this type of damage tends to become mushy, losing the firm, flaky texture that is characteristic of fresh, well-handled fish.
