I recently joined a Community Supported Fishery Program. Once a week I receive fresh caught local fish that I get to take home and prepare. Did I mention it’s a whole fish? The fish is gutted, but I’m in charge of filleting. This got me thinking about what to do with those fishy leftovers.
Following are some ideas for what to do with the remainder of the fish after you fillet it.
Compost: Fish can safely be composted but the smell may attract critters. Use an enclosed style bin (like a tumbler) or keep your compost heap secure. Add plenty of fibrous material like peat moss, grass clippings, and leaves. Stir the pile often, keep it moist, and make sure it’s hot (104 to 160 degrees Fahrenheit).
Fertilizer: Consider making your own organic fish emulsion fertilizer. It is an amazing fertilizer for outdoor plants and vegetables. It does have an odor, so use inside on houseplants with caution. Google “how to make fish emulsion” on the Internet for directions.
Pet Food: Consider feeding the fish head raw to your dog or cat. Raw diet feeders do this all the time. It is a healthy and natural way to feed a pet. Alternatively, you could cook it lightly.
Eat It: Fish heads have a fair bit of meat inside. There are many recipes that use all of the fish. Do an Internet search for fish head soup or fish head curry. If neither appeal to you, make a fish stock by simmering water, fish remains, and any herbs and vegetables that appeal to you. Strain and use as a base for soup.
Any other ideas? I’d love to hear them!

Hi Ruth, that’s pretty amazing what you can do with whole fish. Never knew you could get so much out of a fish. I guess it is a good habit not to waste anything as http://climatarians.org also shows. It prevents unnecessary items in the trash can as well. The amount of waste produced can be drastically reduced if we can find effective ways to utilize the things better.
Cheers,

Thanks Joost for stopping by. I agree-between composting and recycling our trash here is minimized!
