The pond with no fish is the worst affected, the pond with a few fish has some duckweed and the pond with loads of fish has none. Thank you, Donna.

"Sacha" wrote Any chance that frogs and/or tadpoles eat duckweed?! It's taken me years to get rid of the stuff on our pond, had to buy a skimmer (Oase SwimSkim) in the end and that has worked so far. Never seen any of our fish eat it, indeed when they gulp down a mouthful of pellets and accidentally get some Duckweed too they spit it out. Maybe it's not carp that eat it. -- Regards Bob Hobden |

"Pete C" wrote Koi don't, I beg to differ Bob..........but hey, what's a bit of duckweed between friends ;') Funny that 'cause in the 30+ years I've kept Koi I've never seen them eat it, they always spit it out if taken by mistake with a mouthful of pellets and I've certainly never seen them deliberately eat any.

I would guess that the OP would know the difference. We had huge problems on the shoot with a pond being covered with a thick carpet of duckweed and despite a serious effort to remove it during which we scooped off around 60-80 kilos a week over a month or more it came back within days. Arable land nearby? That growth could be due to fertilisers leaching into the pond.

I'm told - but haven't tried it - that duckweed is very nutritious and makes good a soup ingredient. The odd water snail amongst it should provide a little body... Common Koi and Grass Carp do eat duckweed and I did a little research and found freshwater shrimp also do . The shrimp will eat anything, but you'd need a lot of them.
