The Wonders of Feeding Duckweed

Recommended Posts

Hi all,

Sharing a quick vid of the orandas snacking on duck weed & lol....excuse my sister's singing in the background.

They usually get a handful of duckweed one or twice a week which is netted up from one of my outdoor tubs

Some benefits of duckweed:

-fast growing & easy to cultivate

-high protein source

-efficiently used by goldfishes & highly digestible

-FREE & you'll have an unlimited supply - all you need is a tub or bucket

-natural laxative - clears digestive tract preventing constipation & swim bladder problems

duckweed is 5 star stuff...just that and some protein of some source (in the wild it would be insects,etc)and goldies would be big healthy guys..notice most fish who are vegetarian or omnivore dig the weed :pop2::pop2: see tropheus etc...and I like tanks that look more natural and duckweed and bannana lillies,etc do this and make goldy tanks look great...nice collection of goldies too mate :hail: great little vid...that little chu da fella(at end of video) is a chunk !:pop2:

I hear what your saying Netty! My rainbows love duckweed!

They all get a weekly feed. I find another bonus of feeding duckweed is that my fish don't eat it all at once. It usually floats around the tank for a couple of days allowing my fish to have a snack every now and then between their daily feedings. It allows them to have a bit more of a natural feeding pattern I guess.

Yeah the stuff never lasts long with my goldies. When I had rainbows they all devoured it quick smart.

Forgot to mention any uneaten duckweed also becomes a natural filter and absorbs nitrates/other nutrients in the water.

I've tried freezing it to make duckweed blocks but unfortunately I think the cold temperature kills the cells within the duckweed so it just turns into mush =\

My friends, we have a problem.

We are heavily out numbered by an aggressive militant horde of duckweed haters.

I have used duckweed as a recovery food for sick goldfish.

The high vitamin content, as well as the extra fibre is a good tonic.

Its also valuable as an occasional suplimental food, to a diet of otherwise processed food.

You can use it for herbivores the same way you use brineshrimp or krill for larger fish.

Silver dollars are also big fans.

Duckweeds are small aquatic plants that float on or near the surface of slow moving or still waters. They are common around the world in lakes, ponds, swamps, and river backwaters. All duckweed species reproduce very quickly and can cover entire bodies of water in thick mats of vegetation during warm summer months.

Common Duckweed (lemna minor)

Common Duckweed is by far the most widespread species of duckweed throughout the world. Also known as lesser duckweed in some places. Common duckweed is native to every continent except Antarctica and is able to survive in waters ranging from 40 – 90 degrees Fahrenheit (5-33 C). This allows this species of duckweed to thrive in a wide range of environments around the world. It is generally light green colored, though different climates and water types have slight color variations.

Common duckweed floats on the surface of water and has between one and three leaves, which each have their own small stem. As more leaves grow they split off into new plants. This is what allows duckweed cover a pond or small lake in a short amount of time. Like most species of duckweed, lemna minor can reproduce rapidly and double in surface area in as little as 36 hours in lakes and ponds with high nutrient levels.

Common Duckweed can spread quickly to cover large areas

Many animals and fish will eat duckweed and can sometimes be used to help control growth in ponds. This species of duckweed is also commonly grown in aquariums and ponds where it can be used as a supplemental food source. Even with fish or other animals feeding on it, duckweed usually needs to be cut back to prevent it from completely covering the surface of small ponds.

Oh looks like frozen duckweed does work, I added water to mine so that must have been the problem doh! :econf:

Just the usual Phil, planted tanks, native shrimps & goldfishes. How about yourself?
