Fish oil is often used when going hunting for small mammals. When the fish oil is applied to your body, the animals will smell it and will naturally follow the smell. There are also many health benefits from consuming fish oil capsules, especially when it comes from salmon. Making your own fish oil can save a lot of money in the long run. Continue reading to learn how to make fish oil.

Cut the meat of a fish into 1-inch pieces. A fish that is high in fat will produce a better oil. Try using trout or salmon. The belly of the fish has the highest fat content, so use all of the belly meat.

Put the fish chunks into the glass jar, filling it about halfway full. Put the washcloths over the top of the jar, and secure it in place with the rubber band. The washcloth will let gases escape from the jar and prevent insects from getting inside. If a fly or other type of insect were to lay eggs inside the jar, the oil would be ruined.

Let the jar sit in the sun for 4 weeks. There will be liquid sitting on top of the fish. You will see fluid produced from decomposition and a thick yellow substance floating on top of the fluid. The yellow substance is the fish oil.

Take the washcloths off the jar so you can get to the oil. Skim the oil off the top of the liquid using a spoon. You can put the oil into a small plastic container of your choice. Whatever type of container you use, make sure it can be sealed.

Dispose of the contents in the jar. You can simply dump the remains on the ground or bury it in a small hole. Fish will not harm your soil or the environment.


  • Make sure the jar is in a spot that animals cannot reach.
