Types of Fish Fertilizers

Fish Blood and Bone – Fish Meal

Fish meal is made up of the blood and bones of small oceanic fish like anchovies, sardines, and herring. 

To do this, the fish are pulverized, and then the oil and water leftover is pressed out, leaving just the remaining solids from their blood and bones.

Fish Emulsion

Fish emulsion is a combined and broken-down mixture of all the leftovers that remain from fish processing plants. This includes parts or whole fish left behind. It turns into a dark brown and highly concentrated liquid that can be mixed with water to dilute the concentration and then either used to water plants or to spray or add to the soil as fertilizer.

  • High Nitrogen – This is especially helpful to lawns or leafy green plants that require this high nitrogen content
