Quantity: 5 fish per box
Size: 10–12 inches
Species: Grass Carp (Triploid – Sterile)
Certification: Federal Triploid Verification Included
Certified Sterile Vegetation Control
This listing includes five (5) certified triploid grass carp in the 10–12" size class, structured for controlled vegetation management in small to mid-sized ponds.
These fish are not rushed parcel shipments. They are scheduled in alignment with federal certification cycles to ensure sterility verification and regulatory compliance.
Federal Triploid Certification
Every batch of triploid grass carp is tested for sterility under protocols overseen by the U.S. Fish and Wildlife Service.
Certification frequency:
Each order includes an official certificate with a raised seal issued in the customer’s name.
You should retain this certificate for your records, as many states require proof of triploid status for legal stocking.
Why 10–12 Inches?
At 10–12", grass carp are:
This size class offers strong survival and predictable vegetation engagement.
What They Control
Triploid grass carp are most effective on:
They are not effective on filamentous algae or surface scum. Correct plant identification is critical before stocking.
Delivery & Scheduling
Because certification occurs on a set schedule, deliveries are coordinated around testing dates. This ensures:
Delivery timing is confirmed directly with you once certification is complete.
Stocking Considerations
Before ordering, evaluate:
-
Pond acreage
-
Vegetation density
-
Predator population
-
Long-term habitat goals
Understocking may delay results. Overstocking may remove too much vegetation and reduce habitat structure.
Triploid grass carp are a long-horizon biological tool designed for sustained vegetation suppression — not an immediate chemical substitute.
