If frozen fish thaws can it be again?

No, frozen fish should not be refrozen as it can compromise its quality and safety. When fish is frozen, the ice crystals formed can damage the cell structure, and refreezing can further exacerbate this damage, resulting in a mushy texture and loss of flavour. Additionally, refreezing can increase the growth of bacteria and compromise the safety of the fish. It is recommended to thaw frozen fish only once and cook it immediately without refreezing to ensure optimal quality and food safety.
