Triploid Grass Carp

What are triploid grass carp?

Grass carp are plant-eaters, consuming 30 to 100% of their body weight daily in vegetation. They can grow to 65 to 80 pounds, gaining 3 to 10 pounds per season based on available vegetation. Triploid grass carp have three sets of chromosomes instead of the usual two (diploid), achieved through heat or pressure in the egg stage. This makes them functionally sterile, ensuring they won’t reproduce.

How many triploid grass carp do I need and what size should they be?

To address vegetation issues, stock 3 – 7 grass carp per acre, with 7 per acre recommended by Texas Parks & Wildlife for most cases. Avoid excessive stocking. Ensure grass carp are at least 8″ long, and if big bass are present, they should be 11″ or longer.
