*Gaigher, et al. (1984) compared the growth of hybrid tilapia fish on commercial pellets vs. duckweed. The fish were cultured at high densities in an experimental recirculating unit for 89 days with duckweed (Lemna gibba) or a combination of duckweed and commercial pellets. They conclude that a combination of pellets and Lemna gave the best performance:

#Christian Brown you have to add fish water to the trays if you want the duckweed to grow properly.

Thanks for the video there is not enough information on growing duckweed. I want to make my aquaponics self sufficient and duck weed is a big part of that.

Great shot of duckweed growth containers. Your duckweed is looking healthy. What is the length of your roots? If more than an inch and a half, your protein levels will be low. Optimal nitrogen is approx 50 mg/l total nitrogen to get 42% protein. I'm a huge advocate of duckweed for fish, poultry, compost and green mulch in sustainable urban farms. It's been great to run across your video.

you genetically splice the flower or bud with the new developing cell's of the duckweed and continue to do this at lest 50-100 times and you'll get a cross breed that well reproduce on it own and become smoke able :)

Would somesone help me what is wrong with my duckweed? Growing condition: 1) water temp less 30 degree C 2) sunlight cover: 30-50 percent. 3) Algea not seen, however a cloudy thin film is floating on water. 4) Nutrition not known, but roots longest are 20mm. average is 12mm. Last time it happened I add in a bit NPK fertilizer but it did not help. 5) First turning white then yellow then die 6) PH 6-6.5
@nathanaelspecht26167 жыл бұрын
For all photosynthetic organisms that I know of, turning yellow is a strong symptom of nitrogen deficiency. I suggest you keep adding more and more nitrogen. High-nitrogen compost will do, but manure is better/more concentrated. Duckweed, aka watermeal, thrives in very-high nitrogen environments. Its now being used in some waste-treatment plants (essentially vats of fertilizer-water). Here is a good link with more info: www.mobot.org/jwcross/duckweed/practical_duckweed.htm

Does the duckweed spread through an Aquaponic Grow Bed system in any way if it is not all eaten by the fish, or is it only for fish farming.

How do you aerate the shallow culture tanks? Does duckweed need oxygen? Is this plain water or with some aditive?
@Potatodude22310 жыл бұрын
you should aerate it with a bubbler at least. You can use guppies or larger fish to put into the duckweed tank, but they may eat the duckweed, so its best to use the fish water from your tanks. The duckweed need nutrients too, and will take that from the water from the fish tank, the waste that is in the water.

anil SINAM - Pure water alone is not enough. Usually aquatic plants make for a fantastic "cleaning" system. Particularly for water contaminated with large amounts of organic matter (polluted). That's an added benefit. On the other hand for growing solely with clean water, adding earth and manure will "pollute" the water enough for them to thrive. Dissolve some manure in the water and see the difference. ;-) Fish aquaculture can also benefit. Cleaning the water from the fish dejects, while raising Bio mass at the same time.
