The article below about making your own fish emulsion says to use fresh fish, but I saw another article that said you can use canned fish. When you open the can, if it smells or looks like it has gone bad, I would not use it. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/fish-emulsion-fertilizer.htm
