First, put the grouper on the chopping board, put a layer of salt on its body surface, clean the mucus on its body surface, then tie several steel saw blades together with a rope, and finally scrape the scales reversely.

The scales of grouper are hard, so they need to be cleaned in a special way. First, put the bought grouper on the chopping board, coat a layer of salt on its body surface and clean the mucus on its surface. You can also use several beer bottle caps to nail on the board for scaling.

Then tie several steel saw blades together with a rope, and then you can scrape scales in the opposite direction. If you don't have hacksaw blades at home, you can nail a few beer bottle caps on the board and then beat the grouper with the board to remove the scales.

How to kill grouper

1. Hold the head and tail of the grouper with both hands, and then lay it flat on the chopping board or on the ground (or put the grouper into a larger bag, and then beat it hard until the grouper is knocked out or knocked down) to ensure that it can be killed or knocked down.

2. Put the grouper on the chopping block (the right side of the fish is facing down and the left side is facing up), then press the left side of the grouper's head with your left hand, and cut it with a knife from the left cheek with your right hand until the fish belly is completely cut open.

3. Take out the internal organs of the grouper (whether to keep gills can be decided according to personal preference, and if the grouper is large, the liver can also be kept), and then wash the fish thoroughly.
