Silver Carp
Silver Carp (Hypophthalmichthys molitrix) are invasive filter-feeding fish that have established populations throughout Louisiana's river systems.
Scientific Name: Hypophthalmichthys molitrix
- These deep-bodied, laterally compressed fish are highly silvery when young, fading to greenish on the back and silver on the belly as they age.
- Their eyes sit far forward on the head, below an upturned, toothless mouth, and they lack the dark blotches of Bighead Carp.

What to know
Habitat Distribution
- They prefer open areas and eutrophic zones of standing or slow-flowing waters, occupying the upper and middle layers of the water column.
- Silver Carp favor contiguous backwaters, tributary streams, main-channel borders, side-channel borders, and slow-flowing portions of large rivers where water pools, while avoiding main-channel habitat.
Key Locations
- In Louisiana, they're found in the Mississippi, Atchafalaya, Red, Ouachita, Barataria, Teche/Vermilion, Sabine, and Terrebonne river systems.
- The shallow floodplain lakes of the Atchafalaya Basin are known hotspots where jumping Silver Carp are commonly reported.
Specific Spots
- Focus on contiguous backwaters, tributary streams, side-channel borders, and slow-flowing river sections where water pools - avoid main channel areas.
- Target depths in the upper and middle water column where they typically feed, particularly in shallow areas of the Atchafalaya system and other backwater habitats throughout Louisiana's major river drainages.

Since they can tolerate a wide range of conditions, they may be catchable year-round except during extreme temperature periods.
How do you catch Silver Carp in Louisiana?
Gill netting and electrofishing have proven most effective for capturing larger specimens in research settings, though these methods aren't available to recreational anglers.
What do Silver Carp eat?
These plankton-eating fish primarily consume phytoplankton through filter feeding, though they also ingest zooplankton.
