This recipe comes from the Korean Natural Farming tradition where it is referred to a Fish Amino Acid (FAA).
What makes this recipe so special is that unlike most commercial fish fertilisers it is fermented and not cooked. This retains the fats and microorganisms that would otherwise be eliminated through boiling. The final product also smells far better and not at all offensive. Blue-Backed, fish such as sardines, mackerel and tommy ruff are ideal because they have high levels of omega oils. However, you can use any fish and/or fish scraps in this recipe. There is no need to gut or scale the fish either. The microorganisms will eat through all but the toughest scale and bone.
Fish (Blue Backed Preferred)
Method: Chop Fish into thumb sized cubes. Mix in equal weight Raw Sugar and a splash of Lactobacillus Serum. Ferment for 6 months for optimal results, although it is usable after 3 months in warmer conditions.
