Triploid Grass Carp - Nature's aquatic weed control!

Triploid Grass CarpEarth Friendly Many aquatic weeds including hydrilla cause serious problems in water systems throughout Florida. Triploid Grass Carp are a safe and effective biological method that is often used in conjunction with other methods to bring about both short and long term control of weeds.

Triploid Grass Carp, also known as the White Amur, are a fish native to Asia that we introduce into ponds for aquatic weed control. The difference between these, and the grass carp that are a problem throughout the US, is that these have been genetically altered to have an extra set of chromosomes at hatcheries. This makes them sterile, ensuring that their populations do not increase.


Advantages of using Triploid Grass Carp for weed and algae control includes:

  • Longevity – they live an average of 5-9 years
  • Consistency – they never stop eating
  • Cost – once established the lake provides for all their needs
  • Effectiveness – they prefer some of the most unfavorable weeds (or the worst)

Unlike other control methods which are determined by the area of water, fish stocking for vegetation control is based on the amount of weeds present. Additionally, because a variety of factors can influence the feeding rate of grass carp, your lake will be evaluated by our specialists to determine the best stocking rate.

Florida requires a permit for use or possession of grass carp, and only certified triploid grass carp can be used for aquatic weed management - our team has the experience you need to help with obtaining all necessary permits.
