How do you know when fish is spoil?
How do you know when fish is spoil? The best way to determine if fish has gone bad is to smell it. If the fish smells sour or spoiled, throw it out. If the fish has a mild ocean smell, it’s likely safe to eat—but if you aren’t certain, there are other signs you can look for. For example, it’s bad fish if it appears or feels slimy and/or has a dull color.
