The big red-eyed fish scales are tight, it is really difficult to scrape, and it can't be scraped, but the taste is ok.

The big-eyed fish has a special knife for scraping scales, and then it can completely remove the scales and scrape them off little by little.

It's really no good. Generally, places that sell fish can help you clean the fish and scrape off the scales, so you don't need to do it yourself. If you do it yourself, you need to scrape off the back of that kitchen knife a little bit, but it's too troublesome and unskilled.
