Triploid Grass Carp are available in Texas and are tightly regulated by the TPWD, so you need a permit to purchase.  Grass carp are a tool for management of  submerged aquatic weeds  like hydrilla, bushy pondweed, coontail, etc.

Mozambique Tilapia are available for lake and pond stocking in Texas without the need for any special permits.  Mozambique tilapia are a useful tool for the management of filamentous algae and other potentially nuisance vegetation species.  


Triploid Grass Carp

Triploid grass carp have been imported to the United States and are raised here for the  purpose of aquatic weed control. Triploids are sterile, and each fish has been individually tested before final sale.

Grass carp are a great tool for management of submerged aquatic weeds like hydrilla, bushy pondweed, coontail, and other soft-tissue species.

They are not a good choice for most floating weeds, shoreline emergent weeds, or filamentous algae.  
Stocking of grass carp requires a permit from the Texas Parks & Wildlife.

The TPWD currently allows the stocking of up to 10 grass carp per surface acre. We stock the 12"+ size triploid grass  carp, but smaller grass carp are also available.


Mozambique Tilapia

Mozambique Tilapia are the only species of tilapia that are legal to stock in private impoundments in Texas without a permit. These fish are  a control option for several types of nuisance aquatic vegetation.  

They will help to control the following species at adequate stocking rates:

  • Duckweed
  • Watermeal
  • Mosquito Fern
  • Filamentous Algae (Pond Scum)

The beauty of these fish is that they will essentially convert nuisance aquatic growth to fish weight and become part of the food chain for top-end predators like largemouth bass, catfish, etc.
