Tilapia is a lean, mild-flavored freshwater fish, and like other lean fish on this site (cod, halibut), its low fat content lets it freeze considerably longer (6-8 months) than a fattier fish like salmon or tuna, since there's less fat present to slowly oxidize and turn rancid over a long freezer stay.
Because tilapia is one of the most widely farm-raised fish globally, most of what's sold in US grocery stores has been previously frozen at some point during processing and shipping, even when displayed as "fresh" at the seafood counter — worth knowing if you're deciding whether to freeze a "fresh" purchase yourself, since it may have already been through one freeze-thaw cycle.
Tilapia's mild flavor and firm, flaky texture make it a common substitute in recipes calling for a more expensive white fish, and its storage and cooking behavior track closely with other lean white fish like cod, following the same general fridge (1-2 days) and safe-cooking guidance.
A fillet that releases an unusual amount of liquid when thawed may have been previously frozen and thawed once already before your purchase, which is common but worth accounting for by cooking it promptly rather than refreezing.
Farm-raised tilapia's mild flavor means it picks up marinade flavors quickly, so a short marinating time before cooking is usually enough compared to a more strongly flavored fish.
Storing tilapia fillets in a single layer, rather than stacked, in the fridge helps them chill more evenly before cooking.
A fillet that's been sitting in its original packaging for close to its use-by date is worth smelling before cooking, even if it looks fine, since smell is a more reliable early indicator than appearance.
Freezing tilapia in a small amount of water, essentially a mini ice block, is a technique sometimes used to protect delicate fillets from freezer burn during longer storage.
Farmed tilapia fillets are typically thin and mild, with little fat to slow spoilage, so packing them on ice rather than just refrigerating extends their short window before cooking noticeably.
Patting a thawed fillet dry before cooking helps it sear properly rather than steam, since thawed fish often releases a bit of surface moisture.

Frequently asked questions
How long does raw tilapia last in the fridge?
1-2 days, the standard window for fresh fish generally.
Why does tilapia freeze longer than salmon?
It's a much leaner fish, with far less fat to slowly oxidize and turn rancid during a long freezer stay — the same reason lean fish generally (cod, halibut) outlast fattier fish (salmon, tuna) in the freezer.
Has store-bought 'fresh' tilapia usually been frozen before?
Often, yes — tilapia is predominantly farm-raised and shipped internationally, so much of what's sold as fresh at a seafood counter has already been through a freeze-thaw cycle during processing, worth knowing before freezing it again yourself.
What are the signs raw tilapia has spoiled?
Tilapia's naturally mild fillets should smell like almost nothing at all when fresh, so any sharp ammonia note, a graying or yellowing tinge to the flesh, or a slick, slippery surface are clear signals it's turned.
