There are many ways to euthanize a fish, but one of the most popular methods is using baking soda. This is because baking soda is a very effective and humane way to kill a fish. Here is a step-by-step guide on how to euthanize a fish with baking soda:
Fill a bucket or bowl with water and add baking soda to it. The ratio of baking soda to water should be 1:1.
Place the fish in the bucket or bowl of water and baking soda.
The fish will start to experience respiratory distress and will eventually die.
Once the fish is dead, you can dispose of it in whatever way you see fit.
While this method is considered to be one of the most humane ways to kill a fish, it is important to note that some people may find it upsetting. If you are someone who does not want to see the fish suffer, then this may not be the method for you.
