If you can, make sure you ask the vendor to help you remove the scales when you buy the fish, as tiger garoupa is very strong and the scales are very close to the body, so it's harder to remove them by yourself.

If you can only remove the fish scales by yourself, you can refer to the following method: put the bought tiger spotted fish on the top of the board and smear a layer of salt, so that the mucus on its surface can be cleaned up, and then the hacksaw blade with a rope all tied together, the reverse of the fish scales can be scraped. If you don't have a hacksaw blade at home, take a few beer bottle caps and nail them to the board and then hammer them against the grouper to remove the scales.
