Aquatic Weed Harvesting

Aquatic Plant Harvesters offer an environmentally sound method of controlling excessive aquatic plant growth and unwanted vegetation in waterways of all sizes. These heavy duty work boats are highly efficient in the management of submerged, emergent and free floating vegetation.

Like an underwater lawn mower, an aquatic weed harvester cuts the vegetation, collecting and storing the weeds on board. Aquatic weed harvesters are fitted with a pick up conveyor at the forward end of the machine, which can be lowered under water to cut weeds. One horizontal and two vertical cutter bars sever the vegetation as the machine moves forward through the water and when the storage hold becomes full the weed harvester returns to shore to unload.

Depending on the size of your lake, the type of your weeds, the percentage of weeds you would like to remove and how quickly you would like to harvest them, we will work with you to design a fully customizable weed harvester to meet your specific needs.

EFFECT OF AQUATIC WEEDS ON THE ENVIRONMENT

Spread of Disease

Aquatic weeds create situations which are ideal for mosquito growth. The mosquitoes are sheltered and protected from their predators by aquatic weed roots and leafy growth and are responsible for the spread of Malaria, Yellow fever, river blindness and encephalitis. Snails are able to multiply, playing a crucial role in the life-cycle of blood and liver flukes (parasitic worms) as they shelter and find sustenance among the root zones. Schistosomiasis and fuscioliasis diseases spread as the floating weeds carry the snails to new locations.

 

Life of the lake

Water bodies which are places of recreational and aesthetic use are badly affected by unwanted growth of aquatic weeds. They hinder the movement of boats and affect other aquatic activities. The decomposition of weeds causes silicious material and other insoluble salts to settle at the bottom of the water body. Dense weed growth slows the flow of water in rivers, canals and drainage ditches allowing silt to settle and be deposited on the bed of the water body. This increase in silt deposition raises the bed level and finally affects the life of lakes.

 

Extinction of Fish

Fish production is greatly affected by the presence of floating and submerged aquatic weeds. Isolated weed beds may be tolerated, providing shelter and shade for fish, but when the growth becomes thick and covers the entire water body, it can be lethal for fish growth. Fish may suffocate from a lack of oxygen which may cause their death. When floating and submerged aquatic weeds become extremely dense, many fish species are unable to exist in such environments and gradually become extinct.
