Fish emulsion fertilisers is made with fish remains. It is extremely nutrient-rich when used on houseplants and vegetable gardens. While you can purchase the fish remains by the bottle in speciality stores and online, you can also catch a fresh fish to eat and save the remains or purchase a fresh fish at the butcher counter in your local supermarket. After you have the remains, making the fish emulsion fertiliser is simple.

  1. 1

    Place all available fish remains into a 5-gallon bucket. There isn't a required amount, so don't worry if you only have the remains of a single fish available. However, the more fish remains you add to the bucket, the more nutrient-rich the emulsion will be.

  2. 2

    Fill the bucket with water until it is 3/4 full. Stir the fish remains around in the water well.

  3. 3

    Allow the bucket to sit for a few days -- at least two, and more if you have the time. Stir the mixture periodically throughout the days.

  4. 4

    Pull a piece of cheesecloth tight over the top of the bucket and secure it by tying a string around the rim.

  5. 5

    Carefully tip the bucket over and strain all the water into your preferred watering cans. You can then pour the fish emulsion fertiliser into the soil around the plants you wish to enrich.
