Dams on constant-flowing streams or those that overflow frequently should not be populated with triploid grass carp unless they can be effectively sifted. This means that at least one 2-inch square mesh material is used on pipes or earth overflows. Leak prevention helps protect beneficial aquatic vegetation in our public waters. Although triploid grass carp cannot reproduce, it can live for years, potentially migrate to sensitive areas and consume a lot of vegetation. Triploid grass carp are available in Texas and are strictly regulated by the TPWD, so you`ll need a purchase permit. Grass carp is a tool for managing submerged aquatic weeds such as hydrilla, bushy pond grass, coontail tail, etc. Facts: Grass carp may be an effective biological control agent for some varieties of soft-stemmed submerged aquatic vascular plants and branched algae. In some cases, aquatic plant control has been carried out for periods of 5 to 10 years. Under the right conditions, grass carp in ponds can perform more sustainable, economical and less labour-intensive aquatic plant control than chemical or mechanical control methods. To add grass carp to a Texas lake, the landowner must obtain a permit from the Texas Parks and Wildlife Department.
Grass carp, Ctenopharyngodon idella, is another invasive carp species found in the United States and is one of the largest members of the Minnow family. The body is elongated with moderately large scales, while the head has no scales. There are three single rays and seven branched rays on the dorsal fin. Herbivorous carp are silvery to olive, do not have the golden hue of carp and do not have barbels. This species typically reaches sizes of 65 to 80 pounds in its natural habitat, but a few larger individuals have been caught. In good ponds, grass carp is a cost-effective tool for managing your pond and can really improve the quality of fishing. However, it is important to know how much you need and whether the vegetation is suitable for sowing grass carp. Bushy pond grass, American pond grass and hydrilla are favorite foods. Grass carp is not effective for rushes, filiform algae (pond moss or moss), water primroses, coontail, Eurasian watermilfoil or cane vial.
Grass carp is a subtropical to temperate species native to the great rivers and lakes of East Asia. Its original range extends from southern Russia to northern Vietnam and coastal waters inland. Grass carp was first imported into the United States in 1963 to control macrophytes in aquaculture facilities in Alabama and Arkansas, and quickly escaped into the open waters of Arkansas. In the early 1970s, numerous reports of grass carp were captured in Missouri and Mississippi. Since then, grass carp has spread rapidly due to widely dispersed research projects, government stocking, unauthorized releases, interstate transportation, escapes from agricultural ponds and aquaculture facilities, natural spread of introduction sites, and widespread stocking of grass carp as a biological control of aquatic plant interference in ponds and lakes.

(1987). Triploid grass carp: status and impact on management. Fishing, 12(4), 20-24 grass carp are potentially harmful to native resources. Currently, only triploid (sterile) grass carp are legal in Texas, and a permit is required to obtain them. Since grass carp is a potentially invasive species, a fisherman who catches one must immediately remove the intestines, except in waters where a valid triploid carp permit applies. In these waters, any herbivorous carp caught must be returned to the water immediately intact. Although triploid herbivorous carp are still used in macrophyte care, they do not pose a threat to reproduction. However, diploid and viable herbivorous carp are still widely used in the United States and culling their numbers may prove difficult to do. In Texas, there are parameters involved in the extraction of grass carp.
These fish are considered invasive species and are illegal without permission. The permit can be obtained from the Texas Parks and Wildlife Department with a quick assessment of your lake. This process went fully live towards the end of 2020 and can take 4-6 weeks – you may want to visit the TPWD website at the end of January to make sure you have your approval for the coming summer. Grass carp must be triploid (or sterile) to be legal to buy. We know what you are thinking: « If the fish must be sterile, why do I need a licence? » These fish are allowed so that TPWD can track the location and number of grass carp in the environment. Mozambican tilapia is the only species of tilapia that can be legally populated in private reservoirs in Texas without a permit.
