Grass Carp

Grass Carp

Grass carp in Oklahoma are large, invasive fish imported from eastern Asia in 1963 for aquatic vegetation control. Currently found in most Oklahoma reservoirs, grass carp reproduction has been verified in Lake Texoma by ODWC biologists.

Physical Characteristics:
  • They have torpedo-shaped bodies with blunt heads, moderately large scales with dark edges creating a cross-hatched appearance, and olive-brown coloring with silver sides and white bellies.
  • These powerful fish can reach impressive sizes, with Oklahoma's state record at nearly 69 pounds, though most pond fish won't exceed 20-30 pounds.

Grass Carp FAQ

Answers from onWater's species guide.

What flies work for Grass Carp in Oklahoma?

Size 12-16 beadhead woolly buggers in black, beadhead hares ears (sizes 14-18), smokejumper midges (sizes 18-22), and CDC caddis patterns (sizes 12-14). Tie flies in three weights: heavy for deep water, medium for slow sinking, and light for suspension.

When is the best time to fish for Grass Carp in Oklahoma?

During spawning periods (April-July in similar latitudes), fishing pressure should be avoided to prevent disturbing reproductive activities.

How do you catch Grass Carp in Oklahoma?

For fly fishing, lead grass carp by 10-15 feet and slowly strip flies in front of their face - never cast directly at them. When they take the fly, don't set the hook; instead, slowly lift the rod to noon and let the fish hook itself.

What do Grass Carp eat?

Grass carp are primarily herbivorous, consuming up to three times their body weight daily in aquatic plants, though they also eat invertebrates like crayfish and occasionally small fish when vegetation is scarce.
