How long does your catch keep frozen?
Search your species below for its freezer quality window, how to pack it, and how to thaw it safely. The big rule: oily fish keep far less time than lean fish, because the oils go rancid. These are quality guidelines from USDA FSIS home-storage guidance. See cooking your catch for what to do next.

⚠️ Times assume a freezer held steadily at 0 F, fish bled, cleaned and chilled quickly after the catch, and airtight packaging. Air is the enemy - a vacuum sealer or a good ice glaze roughly doubles quality life over loose wrap. Always thaw in the refrigerator or a sealed bag in cold water, never on the counter, where the surface warms into the bacteria danger zone. Freezing does not make fish safe to eat raw; that needs specific commercial freezing standards.
