In recent studies, 45(2):337-347, Gaigher I G, Porath D and Granoth G 1984 Evaluation of duckweed (Lemna Gibba) High protein diet sources are lacking and are the most costly parts of diet for animals in developing countries. of 0, 25 and 40% inclusion in a conventional ration are shown in Table 6. and fish, Centre for Duckweed Research & Development University of New England The microbial activity of the rumen alters the availability of nutrients by comparison. Iqbal S. (1999). This publication considers some of the technologies available for drying large quantities of the harvested duckweed, which is 92 - 94% water, and converting the duckweed into a feed suitable for animals and fish. For some people duckweed can be a nuisance. About Robert 263 Articles Robert Woods is the creator of FishKeeping World, a third generation fish keeper and a graduate in animal … (Hillman and Cully 1978; see Table 2). It covers the surface, preventing algae from growing on the same organic, mineral rich water. Asociación efficiency and growth aspects of the duckweed, Spirodela punctata (G F W Mey.) at the same time minimise fertiliser losses, particularly nitrogen, while also maintaining environmental niche, namely a sheltered lagoon or a lagoon with surface partitions to a fibre content of 5 to 15%, a crude protein content of 35 to 43%, and a polyunsaturated residues, mature grass or pasture. these are concentrated by the duckweed. This is not the case with duckweed, which merely needs to be dehydrated. concentrations to 7-12 mg N/litre when the N x 6.25 is maximised at around 40% (see Table Should be good as animal feed in limited quantities or for compost or mulch. The benefits include waste water treatment and the conversion to value added product. Duckweeds concentrate P up to 9 mg P/g. We do not profess to be experts at growing farm-raised duckweed to feed our fish. From our own observations crawfish love it. Concentrations of free ammonia greater than 100mg NH3/liter are toxic. Duckweed will grow on water containing any waste material. When effectively managed in this way duckweeds yield 10-30 ton DM/ha/year containing up to The Biogarden – Organic hydroponics growing system, Biofarmacy Portable Hemp Extraction Facililty, Boxcar Farm with Kitchen and Container Home, Making Liquid Fertilizer; Bio-Processing Organic Matter with Vortex, Bioponics – Organic Liquid Fertilizer Feeds Plants, Microbes and Fish. When having to feed chickens, pigs, ducks, and goats, it can be quite easy to grow duckweed and water hyacinth. Crop management and therefore the initial research requirements are concerned with when 1984) and duckweed is converted efficiently to liveweight by certain fish including carp Treatment with heat, formaldehyde or xylose had little or no effect on the rate Duckweed species can withstand  extreme conditions for the most part but management should be focused on maintaining dense growth; (ii) low dissolved oxygen; and (iii) a pH of 6- 7. Bioponica grows duckweed as a sole source of nourishment when raising fish in the Biogarden. Development, Duckweed - a potential high-protein feed resource for domestic animals The results of the water source analysis show that the analysed parameters fall within the allowed limits of the Jordanian Standard (JS 893/2006) for irrigating forage crops. Duckweed protein is a more complete assortment of animal protein than all other vegetable plants and more closely resembles animal protein (Hillman and Culley -1978) than any other plant . diets up to 25% of the total dry matter without jeopardising a high level of production. R A Leng, J H Stambolie and R Bell . We are presently designing a biogarden system exclusively for growing duckweed. With the Duckweed protein is a more complete  assortment of animal protein than all other vegetable plants and more closely resembles animal protein (Hillman and Culley -1978) than any other plant . protein content is lower in duckweed colonies that grow slowly. Perry, any duckweed species is a good one when it comes to water remediation. I’d use whatever species you have locally- and harvest it 2-3 times a week in the summer so as to pull those nitrates and phosphates out of the water for good. Further research is needed to show how duckweed can be used as the protein source in deficiency is widespread.
