How Do You control Duckweed in a Pond?

Duckweed is a tiny floating aquatic plant with many uses in the Pond Industry. Duckweed is extremely fast growing, and can double its habitancy in just a few days under ideal circumstances. Duckweed is used as nutrient operate in larger aquaculture applications. The fast growing plant utilizes excess nutrients such as nitrogen and phosphorus, thereby creating a healthier environment for the livestock. They are also a high protein plant, and make an exquisite supplemental diet for aquacultures species such as Tilapia and Grass Carp. Duckweed also has a place in the Aquarium industry. They supply security for timid species, and even supply a breeding medium for some species. For all these benefits, this small plant species can also fast become a nuisance to pond owners. It can overtake a small pond in a matter of weeks, or sometimes, days. Duckweed blooms can deplete the pond of oxygen, resulting in stressful conditions for the livestock. Although propagating can be fairly easy, eradicating a habitancy can be quite difficult.

There are three basic discharge methods; Mechanical, Chemical, and Biological. Although each has its advantages and disadvantages, the style of each pond will dictate the permissible formula to be utilized. The most tasteless coming is Mechanical removal. The most tasteless coming is to simply net the excess plant from the pond. While this may be efficient in smaller ponds, it is often tedious or impossible in larger bodies of water. Surface skimming can be a very efficient way to take off excess plants. This involves construction a face skimmer as the intake for the filtration system. The duckweed will flow into the skimmer, preventing an epidemic. The tasteless downside is the duckweed will consistently clog the skimmer. If cleaned regularly, face skimmers are very efficient in small to medium sized ponds.

Chemical discharge can be very effective, but can also contribute to supplementary issues. Herbicides used to operate live plants can be very detrimental to a living ecosystem, and should be used very sparingly in any natural living environment. In addition to controlling duckweed, these chemicals can also damage more desirable attractive plants, and will badly damage the biological filtration system. This can lead to nuisance algae or even livestock death.

Biological operate can be the safest and easiest to deploy. Grass Carp and Tilapia are two favorite choices for duckweed control. Tilapia in single are often cultured with duckweed as a food source. While these fish may suffice for long-term control, other measures may have to be tried in addition to this. Natural operate is often too slow to operate overgrown populations, but may very well be able to vocalize low levels once the duckweed is under control.

Small to medium ponds tend to fare very well with a blend of face skimming and biological control, while larger bodies of water may want a more involved approach. In the end, Duckweed, like all other pests should be controlled early. Once an epidemic habitancy is established, it can be very difficult, and very time consuming, to defeat.
