Ever wondered how we harvest paddlefish?

Our team recently seined one of our paddlefish ponds and harvested approximately 75 healthy, six-month-old paddlefish, each measuring around 12 inches long.

We intentionally left hundreds more in the pond so they can continue to grow and thrive.

In the photo, you'll see Amelia, our animal scientist, carefully handling these unique and fascinating fish to ensure they're treated with the utmost care.

These incredible paddlefish are now available for purchase!
