Great fertilizer. I tried it, but our dogs would dig up the remains and they were house dogs which got me in instant trouble with the boss as they needed multiple baths to remove the smell after they rolled in the rotten carcasses. Even had staked cages around them that they dug under.A retired guy nearby plants 125 tomato plants, potatoes, green beans, squash, and corn. He is very fair in prices. He will even give me vegetables if I bring the remains by after cleaning fish. He has a furrow dug that allows him to quickly cover up the fish.
Don't know why dogs to that but ours did, so I was banned from using fish guts.
