    Uses for Duckweed

    This list of over seventy uses for duckweed is by no means final, but is meant to give you an inkling of what is possible. I can’t lay claim to developing all of them. A big thank you goes out to all my fellow duckweed enthusiasts from around the world who have been kind enough to share their experiences with me.

    Disclaimer: As this is only a list, please exercise common sense and safe practices in any application.

    Aquaponics, use Duckweed for fodder.

    Duckweed is considered a noxious pond weed in many states

    I've had more than one individual call me by that name.
    Oh, Duckweed. Never mind.

    A friend of mine was working on a project for a company that was growing algae, an extract of which was used in cosmetics. Don't know much in the way of details.

    the big thing is cheap fish, chicken and rabbit fodder for animals. It grows fast and is cheap with 40% protein content

    And will foul props like it's nobody's business.

    I guess it's similar to bamboo...lots of uses, but don't let it go in the wild.

    I had duckweed growing in one of the AP beds last summer. My rabbits would not touch it. Maybe it smelled fishy, I dunno, but they refused to eat it. The chickens were meh about it, though I suppose they'd enjoy it more in the winter when there's not an abundance of green stuff around. Planning to set up another grow bed for it next year, just to feed the fish with.

    @techsar we removed it from ponds every year it's smelly but great compost
    @ditch witch so you did not find it at all useful?

    It did a good job of keeping the sunlight out of the bed so the algae didn't take over. We had some baby bluegill in the tank underneath them and had problems in the past with algae smothering everything, so it was helpful there. Like I said, it smelled fishy, may be why the rabbits weren't fans.
