Fish doesn't stay fresh for long, and experts say it's best to eat it on the day you buy it for the best taste.
But if you can't cook it until one or two days after you've bought it, there is a way to keep fish as fresh as the day it was caught, reports the Daily Mail.
So if you've been putting fish straight into the fridge before now, you've been storing it wrong.
Keeping fish fresh is all to do with the temperature that you store it at.
Fridges are on average about 3 to 4 C, which is simply not cool enough to keep the quality of fish from degrading significantly within 24 hours.
