There have been quite a few questions on how to “fizz” a fish. Below are some videos that show two techniques, through the mouth and through the side. Its all of our responsibilites (boaters and nonboaters) to know how to perform this fish saving technique.
You will also need a needle to perform the fizzing procedure.
If you choose not to use an off the shelf “fizzer”/deflater, a standard 1.5” 18 gauge hypodermic needle will also work.
