Riese aquatic Seaweed removal

Riese Aquatics specializes in seaweed removal and dredging. We remove plants by the root by using Diver Assisted Suction Harvesting (DASH) allowing for invasive plant control without the use of chemicals. This seaweed removal technique is the most effective for aquatic invasive plant management, while improving the ecosystem’s health. 

We also offer a variety of dredging options!

We remove nuisance seaweed like these lily pads from boating areas. Our service manually removes the plants by the root, ensuring the longest lasting treatment! Seaweed removal greatly reduces the build-up of sediment over time. 

Before and after photos of our shoreline cleaning, once we have removed the submergent vegetation from your waterfront, we will clean the debris from your shoreline! We also offer pond cleaning!

Truxor T30 Doro Digger

Our Truxor T30 equipped with our new Doro Digger allows us to perform hydraulic dredging where most excavators cannot! We can excavate in up to 9 feet of water.
