But there are also many other types of food to feed tilapia. This plant biomass, in turn, becomes a high protein food for the tilapias. Nile tilapia requires the same ten essential amino acids as other finfishes. Duckweed is often mentioned in this context, as it is relatively high in protein, rich in Vitamin C and provides roughage. However, variable responses are often reported depending on the source of is the levels of minerals in water that are needed, how often to harvest and the density is, however, highly sensitive to the major nutrient balances in the water. Tilapia will consume duckweed but are a warm water species that cannot survive in temperatures below 55 F. Therefore, tilapia usually cannot be stocked before mid-April or May and will die in November or December.

Note that, there are two verities of tilapias, the blue one and the red belly one. Because tilapia feed on troublesome floating aquatic plant life, such as duckweed and algae, they are gaining popularity as a natural form of biological control for aquatic plant problems. In fact, quite the opposite is true. . This agglutinates the small, numerous cells, which are then raked back into the alimentary canal by the action of the pharyngeal teeth. What do tilapia eat? This can be achieved by planting on the south side of the pond. This extremely successful exploitation of the environment has enabled them to live together and to feed at different, non-competitive trophic levels ranging from species feeding on detritus to the swiftly moving carnivorous forms preying on other living organisms like mosquito larvae. That is also why it is being considered for biodiesel because it has five to six times the amount of starch as corn.

It is said that this screen filter can remove algae of 10 µm (1000 µm = 1 mm) in diameter from the water. Also, starch that comes from duckweed can quickly be changed into ethanol, which it can used instead of corn for ethanol. A series of fine protrusions, the micro-gill rakers, situated on the gill arches may act as a sieve. Tilapia don't do well in cold weather, so this is an option best used in warm-weather ponds. You can simply give them your leftover food and these fishes will be fine. If the tilapia eat all the duckweed start again with a larger supply. With such high reproduction rate duckweed can cover the surface of ponds in just a few weeks.

Tilapia feeding is one of the easiest aspects of farming this fish. The formula feed for tilapia should contain 27% to 40% protein. It tastes like watercress. In the integrated tilapia and duckweed recirculating system, the fish and the waters of the tilapia growout ponds provide the nutrients upon which the duckweed will thrive. Tilapia rendalli feed predominantly on aquatic plants found around the margins of lakes and dams. Duckweed can provide all the protein needs of tilapia and carp — which is why it works great for aquaponics. Please share this article with your friends!

Combining duckweed and commercial fish feed is good, but tilapia grow ok on duckweed alone. As the tilapia sector expands and technology development continues, traditional extensive culture is being replaced by semi-intensive and intensive production systems.

In the integrated tilapia and duckweed recirculating system, the fish and the waters of the tilapia growout ponds provide the nutrients upon which the duckweed will thrive. Here are some of them. Data on nutrient requirements, among other information, are needed for least-cost feed formulation. Protein requirements for optimum growth are dependent on dietary protein quality/source, fish size or age and the energy contents of the diets and have been reported to vary from as high as 45-50 percent for first feeding larvae, 35-40 percent for fry and fingerlings (0.02-10 g), 30-35 percent for juveniles (10.0-25.0 g) to 28-30 percent for on-growing (>25.0 g). When feeding on this algal flora, the fish rasp the algae off the substratum using their chisel shaped mandibular teeth and the food is then processed in a similar manner to that previously described.

They get along well with other fish, and help make the water cleaner thanks to the wide range of plant life that they eat. If the Tilapia prove effective at some control of the issue, its a piece of understanding the whole flow of energy and nutrients. Planktonic algae would appear to be the preferred food of Oreochromis mossambicus and Oreochromis niloticus and are removed from the water by extracting the algae from the respiratory water brought in through the mouth to oxygenate the gills. Some fish would be quite happy with this diet, but a larger number of fish in the world would not do well with this diet. While tilapia nibbles on algae, they might also feed on water plants. Herbivorous tilapia can also feed extensively on periphyton (the algal mats that grow attached to submerged objects) when this is available.

The gill rakers proper are probably too widely spaced to trap any algae but only the very large particles and therefore serve only to prevent damage to the delicate gill lamellae by debris and sand taken in with the respiratory water. In intensive culture systems such as in ponds, raceways, cages, and tanks, feed is the most expensive item, often ranging from 30 to 60 percent of the total variable expenses, depending on the intensity of the culture operation.
