Paddlefish
Missouri’s largest fish feeds on some of the smallest prey: it swims open water with a cavernous mouth filtering zooplankton while its paddle-shaped snout senses the river ahead.

Paddlefish are scaleless bluish-gray fish with a cartilaginous skeleton, tiny eyes, deeply forked tail, immense toothless adult mouth, and elongated rostrum containing electroreceptors. They filter zooplankton with dense gill rakers rather than hunting ordinary bait, and can live for decades while making long spawning movements.
Missouri supports paddlefish through stocking and manages harvest with specialized snagging seasons. Most waters traditionally open March 15–April 30, while Mississippi River seasons differ. Length is measured from the eye to the fork of the tail; closures and 32- or 34-inch minimums depend on the named water, so carry the current MDC regulation card.
- Feeding
- Filters zooplankton through gill rakers while swimming
- Sensory organ
- Electroreceptors fill the paddle-shaped rostrum
- Fishing rules
- Season, minimum length, closures, and allowed methods vary by water
Quick guide
- Learn the living fish first
- Use a hatchery program, legal observation, or a safely handled catch to connect rostrum, mouth, gills, and tail
- Choose the exact regulation page
- Identify the water before reading season, length, method, limit, and closed zone
Connect Paddlefish biology with Missouri’s water-specific rules
- Read the Missouri filter-feeder’s body
- At a hatchery program, legal boat encounter, or safely handled catch.
- Trace the Osage River movement
- Connect Lake of the Ozarks or Truman Reservoir deep water with spring movement toward flowing tributaries and dam tailwaters.
- Carry the current MDC regulation card
- Name the exact Missouri water before writing its season, permit, allowed method, daily limit, eye-to-fork minimum, possession rule, and no-fishing or no-possession zones.
- Measure and decide without delay
- Keep the Paddlefish supported and wet, measure from eye to tail fork, and apply the water-specific retain-or-release rule immediately.
Good to know
Missouri snagging seasons exist because a zooplankton-filtering Paddlefish rarely takes conventional bait. At Lake of the Ozarks, Truman Lake, Table Rock Lake, the Osage River, and the Mississippi River, unusual fishing method never overrides water-specific closures, lengths, limits, or permits.
Notice these
- Paddle-shaped sensory rostrum
- Huge toothless filter-feeding mouth
- Smooth scaleless body
- Forked tail with longer upper lobe
