Our Relationships

‘The Soil Beneath’

We were featured on Country Calendar Episode 26 on Sunday 13th of August 2017 at 7pm on TV One.

Our vision is to enhance the health of our freshwater environment through providing the most affordable, sustainable and effective solutions for the control of aquatic pest weeds, toxic algae’s, and pest fish.

Our environmentally friendly bio-control have proven results right across New Zealand. By using herbivore species of fish known as White Amur (Grass Carp) & Silver Amur (Silver Carp) we can achieve full and effective aquatic restoration and management for Weed & Algae control in Lakes, Rivers, Dams, Ponds, Storm-Water Sites, Recreational Waterways, and Farm Drains.

White & Silver Amur classified as a restricted fish, not pest fish. As they cannot breed in NZ waterways and only eat aquatic vegetation they pose no risk. White & Silver Amur are not like Koi Carp, there is often confusion but our carp are herbivorous, cannot breed & are very useful in the management of aquatic weed.
