What eels are and why they work as live bait
Eels are long, snake-like fish that live in freshwater and saltwater across North America. They are one of the most effective live baits for large predatory fish — catfish, pike, musky, stripers, and saltwater species like tarpon and large sharks all hunt them aggressively. An eel's natural movement in the water triggers strikes that other baits often do not.
Eels stay alive longer than most live baits when handled correctly, and they are hardy enough to survive being cast repeatedly without injury. A single eel can produce multiple fish in a single outing, which makes them economical despite their higher initial cost compared to shiners or crawfish.
The downside is that eels require more care than other live baits. They need cool water, proper aeration, and careful handling to prevent escape. They are also regulated differently than other baits in many states, and some waters prohibit them entirely because they can establish populations if released.
Key Takeaways
- Eels are most effective for catfish, pike, musky, stripers, and large saltwater species, and they stay alive longer than shiners or crawfish when kept cool and aerated.
- Check your state's fishing regulations before using eels, because some states ban them as live bait in certain waters to prevent invasive populations.
- Keep eels in a cooler with ice packs or a bait aerator, change the water regularly, and handle them with wet hands to prevent them from drying out or escaping.
- Rig eels by hooking them through the lips or just behind the gills so they can swim naturally and trigger strikes from large predators.
- Eels are most productive at night and in low-light conditions, especially in rivers, lakes with structure, and saltwater estuaries.
Where to buy eels and what to expect
Most full-service bait shops in coastal areas and regions with strong catfish or pike fishing carry live eels year-round or seasonally. Inland bait shops may stock them only during peak season — typically spring through fall — or may need to order them a day or two in advance. Call ahead rather than assuming they have them in stock.
Eels are sold by the pound or by the individual, depending on the shop. Prices vary widely by region and season, but expect to pay more than you would for shiners or crawfish. Size ranges from 6 inches to over 2 feet; smaller eels (6 to 12 inches) work well for catfish and pike, while larger eels (14 to 24 inches) are better for musky, stripers, and saltwater species.
When you buy eels, inspect them for injury or disease. They should be active and move quickly when handled. Avoid any with visible sores, fungus, or a dull appearance. Ask the shop how they have been storing them — they should be in cool water with aeration, not in a dry container or warm tank.
Keeping eels alive and healthy
Eels are sensitive to temperature and oxygen. The ideal storage temperature is between 50 and 60 degrees Fahrenheit. In warm weather, keep them in a cooler with ice packs or frozen water bottles, replacing the ice as it melts. Change the water in the cooler every two to three hours to maintain oxygen levels, or use a battery-powered aerator designed for bait.
Do not store eels in a regular bucket without aeration — they will suffocate within hours. If you are fishing for an extended period, bring a small aerator or plan to change the water frequently. Some anglers use a mesh bag suspended in the water at the fishing location, which keeps eels cool and oxygenated without requiring a cooler.
Handle eels with wet hands or a wet cloth. Their skin is sensitive and dries out quickly, which stresses them and makes them more likely to escape. Never grab an eel by the tail or squeeze it hard — they are surprisingly strong and can slip out of your grip. Wet your hands before each handling.
How to rig and fish with eels
The most common rig is a single hook through the lips or just behind the gills. Use a hook size matched to the eel — typically a 2/0 to 5/0 for smaller eels, and 6/0 to 8/0 for larger ones. Hook placement matters: through the lips keeps the eel's head up and lets it swim naturally, which triggers more strikes than a eel that is pinned and cannot move.
For catfish, use a simple slip sinker rig with the eel on the bottom or suspended just above it. For pike and musky, cast the eel near structure — fallen trees, weed beds, rocky points — and let it swim. For stripers and saltwater species, fish the eel on a three-way rig or a simple weighted line that lets it move freely in the current.
Eels are most productive at night and during low-light periods — dawn, dusk, and overcast days. Fish them slowly and deliberately; do not cast repeatedly or work them like a lure. Let the eel do the work. Set the hook firmly when you feel a strike, because large fish often take an eel and run, and a solid hookset prevents the fish from throwing the bait.
Regulations and restrictions on eel bait
Before you use eels, check your state's fishing regulations. Many states allow eels as live bait in most waters, but some restrict or ban them in certain lakes, rivers, or regions. The reason is that eels can establish invasive populations if they escape or are released, and some states are trying to prevent that spread.
Saltwater regulations vary by state and region. Coastal states generally allow eels, but some have seasonal restrictions or limits on the number you can possess. Check your state's saltwater fishing guide or call the fish and wildlife agency before you fish.
Never release unused eels into the water. Kill them humanely or return them to the bait shop if they are still alive. Releasing them, even with good intentions, can introduce them to waters where they do not belong and create ecological problems.
Eels versus other live baits for large fish
Eels outperform shiners and crawfish for very large catfish, pike, and musky because of their size, durability, and the predatory response they trigger. A big catfish or pike will often ignore a 4-inch shiner but strike a 12-inch eel immediately. Eels also stay alive longer in a cooler, which matters on long fishing days.
The trade-off is cost and convenience. Eels are more expensive, require more careful storage, and are not available everywhere. If you are fishing for smaller catfish or bass, shiners or crawfish are usually sufficient and easier to manage. Reserve eels for situations where you are specifically targeting large predators or fishing waters where eels are known to be effective.
In saltwater, eels are often the best choice for stripers, large catfish, and sharks because they are tougher than mullet or mackerel and stay on the hook through multiple casts. For tarpon and permit, eels are a proven option, though live crabs and mullet are also productive.
Common mistakes when using eel bait
The most common mistake is not keeping eels cool enough. Eels die quickly in warm water or without aeration. If your cooler is sitting in the sun, they will be dead within a few hours. Keep them in shade, use ice packs, and change the water regularly.
Another mistake is hooking the eel in a way that prevents it from swimming. If you pin the eel through the body or tail, it cannot move naturally and will not trigger strikes. Hook through the lips or just behind the gills so the eel can swim and create the vibration that attracts fish.
A third mistake is fishing eels too actively. Eels work best when you let them swim and move on their own. Casting repeatedly, jerking the line, or working them like a lure reduces their effectiveness. Set the rod in a holder and let the eel do the work.
Frequently Asked Questions
Can I use eels in saltwater and freshwater?
Yes, eels work in both. Freshwater eels are effective for catfish, pike, and musky in lakes and rivers. Saltwater eels are productive for stripers, tarpon, sharks, and large catfish in estuaries and coastal waters. Some bait shops sell saltwater eels specifically, which are often larger and tougher than freshwater eels.
How long can eels stay alive in a cooler?
With proper care — ice packs, regular water changes, and aeration — eels can stay alive for 24 to 48 hours. Without aeration or in warm conditions, they will die within a few hours. Check them frequently and replace ice as it melts.
What size eel should I use?
For catfish and pike, 6 to 12 inches is ideal. For musky, stripers, and large saltwater species, use 14 to 24 inches. Larger eels attract larger fish but are harder to cast and more expensive. Match the eel size to the species you are targeting.
Do I need a special hook for eels?
No, but use a hook size matched to the eel. A 2/0 to 5/0 works for smaller eels, and 6/0 to 8/0 for larger ones. Circle hooks are popular because they hook the fish in the corner of the mouth, but J-hooks work fine if you set the hook firmly.
What if my state bans eels in certain waters?
Respect the regulation and use a different bait in those waters. The ban exists to prevent invasive eel populations. Check your state's fishing guide or call the fish and wildlife agency to confirm which waters allow eels before you fish.
