Duckweed

[Mike Burn]

Help ! First timer on this group, with a problem - Duckweed. I have never
knowingly introduced it to my pond, but now it is taking over, and the three
fish are no longer seen (Ghost Carp and goldfish). What ferocious fish can I
introduce to devour the duckweed ? (But not the other fish.

Many Thanks

Mike

Hmmm, that's a new one, usually the fish you have are suggested to eat it.
Stop feeding them, I assume you are? They will eat the duckweed. If that
doesn't work, get a Japanese Koi over 6" (course all fish should go thru a
minimum 6 week quarantine, especially koi, before going in your pond).

Many thanks - I'll go for some more fish - wasn't sure whether duckweed was
a preferred dietary item, though ! Don't know about 6" Koi, though - a bit
pricey !

==============
There is a duckweed that GF and koi will not eat no matter how hungry they
are. It doesn't have the smooth round edges or shiny surface of the one
they will eat. If you have that type infesting your pond you need to net it
out. Spread it around your yard as it will enrich the soil.

It's not a plant it's an infestation. I have it everywhere and hate it. You
CAN remove it manualy with a net. Do it every day till it's gone. You'll
get quite sick of doing this vut eventually you'll win out.

Yiou muct remove EVERY spec. One stupid lousy leaf and it can all come back
from that.

well.... if the fish wont eat it then try a protein skimmer. gradually it will float
along and get sucked into the skimmer where it can be removed. Ingrid

I think you just mean "skimmer". Duckweed would clog the venturi in a
protein skimmer pretty effectively.

Yes, you're very right! We could have a misidentification here.

Look up Azolla & Duckweed and compare the pictures.

Ingrid mentioned skimmers. There are skimmers that don't have to be built
in, work on a small pump w/spray bar that push surface debris into a net.
This might work very well for you, if what you have is Azolla not Duckweed.
Re: Japanese Koi, go for the cheaper pond quality ones, locally we can get
them under $25. ;o) ~ jan

I can't keep duckweed in my ponds. It's eaten within minutes of my dumping
it in. I raise it for them in a large tub behind the outbuilding and
harvest it weekly.

I'm starting to see young locally raised koi and GF selling for as little as
50¢ to $3 each in our PennySaver papers. I'll be advertising to give some
away for free soon if I can't find a shop to take the rest of them. I know
this competes with the stores but I have no choice. We put the plants from
the diamondscale butterfly koi pond in 2 kiddy pools so we could pump down
the pond to fix the berm. The plants were loaded with eggs. Now I have
another few hundred koi to raise and sell next year. Thankfully these are
the butterfly type and should go fast next spring.

Thanks to everyone responding here - I used to net the duckweed and keep it
under control, but what I didn't mention was that the pond is now full of
newt, frog and toad tadpoles .... raking the blanket algae out took me ages
to release the entrapped taddies, skimming the duckweed could take even
longer - don't want to be responsible for multi million deaths - I'm just a
big softie, you see ! I will look for a couple of hungry Koi.
