Composting Fish
Composting Fish
  • When composting such waste as fish parts, the fish waste is mixed with plant waste like wood chips, leaves, bark, branches, peat or even sawdust. As microorganisms break the fish down, they generate lots of heat, which serves to pasteurize the resulting fish compost, in turn eliminating any odor and killing disease organisms and weed seeds. After several months, the resultant product is rich humus lauded as a nutrient wealthy fertilizer for soil amendment.
  • Composting fish has long been used by Native Americans when planting fish with corn seeds to encourage maximum yields. As such, composting fish does not need to be a complex operation. The basic requirements for composting fish are a source of carbon (wood chips, bark, sawdust, etc) and nitrogen, which is where the fish scraps come in to play. A simple recipe is 3 parts carbon to 1 part nitrogen.
  • Other integral factors for composting fish are water and air, about 60% water to 20% oxygen, so aeration is necessary. A pH of 6-8.5 is needed and a temperature of 130-150 degrees F. during the decomposition process (at least 130 degrees F. for 3 successive days to kill any pathogens).
  • The size of your compost pile will vary in accordance to available space; however, a minimum recommendation for productive decomposition is 10 cubic feet, or 3 feet x 3 feet x 3 feet. A slight odor may accompany the decomposition process, but generally occurs toward the bottom of the pile.
  • For fish composting use a half inch wire mesh.
