I saw a few dead large tilapia about 15-18 inches long near the lake bank on my morning walk. I decided to use a skimmer net to scoop them up one by one and bury them in a woodchip pile next to my loquat, mango, avocado, star fruit, and fig fruit trees.
What a nice combination of a free source of carbon (wood chips) and nitrogen (fish) to make perfect plant food! I can feel these fruit plants are getting very excited when I bury the fish next to them :)
Dead fish stink! Yet, there is no smell at all when dead fish is buried in the wood chips. The carbon in the wood chips absorbs the odor of decaying dead fish. Together they will make perfect compost!
