Can We Use the Bones of Fish to Make Bone Meal
Certified GKH Gardening Expert
Fish bones will not have the same nutrients as traditional bone meal because fish have cartilage and mammals have calcium based skeletons. That being said, fish have long been used as fertilizer in gardens so it would still be very beneficial.
You can dry the bones without an over by laying them out on newspaper in a single layer in a dry location. A sunny location would work best. You can also just put the bones as is directly into the soil without drying and they will decompose quickly there.
