Can you reuse oil after frying fish?

Chef's answer
Generally, it's fine to reuse deep-fry oil. In a lot of restaurants, fryer oil only gets changed when it starts to smoke or make food taste "off". It is not necessary to refrigerate used oil. Assuming it's only used for safe food, oil will taste bad long before it will become unsafe (if it ever really does).

Although many of us grew up with relatives who stored their bacon grease in a jar or can set on the counter or on the back of the stovetop, food safety experts don't recommend storing it that way now. Instead, store the grease in the refrigerator (up to 3 months) or freezer (indefinitely).
