Flounder are among the most popular targets for coastal anglers. They offer a unique challenge and provide excellent table fare. These flatfish are masters of camouflage. They lie on the bottom and wait to ambush passing prey. To be successful, you must understand their behavior and use the right techniques. This guide covers everything you need to know to catch more flounder.
Understanding Flounder Behavior
Flounder are ambush predators. They spend most of their time lying flat on the sandy or muddy bottom. Their bodies are perfectly adapted for this lifestyle. Both eyes are located on one side of their head. This allows them to watch the water column while staying hidden. They often bury themselves in the sand to remain invisible to prey.
These fish are highly dependent on the current. They position themselves facing into the tide. This helps them stay stable and lets the water bring food directly to them. They rarely chase prey over long distances. Instead, they wait for a shrimp or small fish to drift within reach. When the moment is right, they strike with surprising speed.
Where to Find Flounder
Locating flounder starts with finding the right structure. They prefer areas where the current funnels food into a small space. Creek mouths and tidal inlets are prime locations. As the tide moves out, it pulls baitfish from the marshes into the main channels. Flounder will wait at the edge of these channels to intercept the bait.
Docks and bridge pilings are also excellent spots. The pilings create eddies and provide cover for smaller creatures. Flounder often sit right against the base of these structures. If you are fishing from a boat, look for sandy potholes in the middle of grass flats. These clear patches are perfect hiding spots for a hungry flatfish.
Jetties and rock piles provide another great habitat. The rocks attract crabs and shrimp. Flounder will tuck themselves into the crevices or sit on the sandy bottom nearby. Always look for drop-offs or ledges. A sudden change in depth is a natural highway for moving bait.
Essential Gear and Tackle
You do not need heavy equipment for flounder fishing. A 7-foot medium-action spinning rod is the standard choice. This rod provides enough sensitivity to feel a light bite. It also has the strength to pull a fish away from structure. Pair this with a 2500 to 4000 series spinning reel.
Your line choice is very important. Many anglers prefer 10-to-20-pound braided line. Braid has very little stretch. This allows you to feel the bottom clearly. Use a 15-to-20-pound fluorocarbon leader. Fluorocarbon is nearly invisible underwater. Flounder have keen eyesight and can be easily spooked by thick lines.
For hooks, use a size #2 to 4/0 circle hook or Kahle hook. These shapes are designed to catch in the corner of the mouth. This is especially helpful because flounder often hold the bait before swallowing it.
Best Baits and Lures
Live bait is often the most effective way to catch flounder. Mud minnows and finger mullet are top choices. These small fish are part of the flounder’s natural diet. Live shrimp are also very productive. When using live bait, hook the fish through the lips. This allows it to swim naturally as you move it through the water.
Artificial lures can be just as successful. Scented soft plastics are a favorite among professionals. Lures like the Berkley Gulp! Shrimp or Swimming Mullet are highly effective. These lures release a scent trail that attracts fish from a distance.
Pair your soft plastics with a jig head. A 1/4-ounce to 1/2-ounce jig head is usually sufficient. Use enough weight to keep the lure on the bottom. If the current is strong, you may need to go heavier. Popular colors include white, chartreuse, and pink.
Effective Fishing Techniques
The most important rule is to keep your bait on the bottom. Flounder will rarely swim up to the surface to feed. You must present your offering within 12 inches of the seafloor.
Drift Fishing
If you are in a boat, drifting is a great way to cover water. Let the current move the boat slowly across a flat or along a channel. Keep your line taut and let your bait bounce along the bottom. This technique allows you to find where the fish are concentrated.
The Slow Retrieve
When fishing from a pier or the shore, use a slow retrieve. Cast your bait out and let it sink. Drag it back toward you with small twitches of the rod. Pause for a few seconds every few feet. Flounder often strike during the pause.
Jigging
Vertical jigging works well around deep structures like bridge pilings. Drop your lure straight down. Lift the rod tip about six inches and let it fall back. Ensure the jig hits the bottom on every drop. This movement mimics a dying baitfish or a hopping shrimp.
Mastering the Hookset
The hookset is the hardest part of flounder fishing. Flounder do not usually strike aggressively. Instead, you will feel a dull “thump” or a sudden weight on the line. They like to grab the bait and hold it in their mouth before eating it.
If you set the hook immediately, you will likely pull the bait away. Instead, wait for a few seconds. Most experienced anglers count to five or even ten before setting the hook. This gives the fish time to fully inhale the bait. Once you feel steady pressure, lift the rod firmly to secure the hook.
Best Tides and Times
The best time to fish is during a moving tide. Flounder are most active when the water is flowing. The outgoing tide is generally considered the best. It flushes prey out of shallow marshes and into the waiting mouths of the fish.
Incoming tides are also productive. They bring cooler, oxygen-rich water into the estuaries. High tide allows flounder to move into very shallow areas that are usually dry. Fishing during slack tide is often difficult. When the water stops moving, the fish stop feeding.
Early morning and late afternoon are the best times of day. Low-light conditions make flounder feel more secure. They are also more likely to move into shallow water during these times. On overcast days, the fishing can be good all day long.
Frequently Asked Questions
-
What is a doormat flounder? A doormat is a term used by anglers to describe an exceptionally large flounder. These fish are usually over 20 inches long and look like a small rug or doormat when pulled from the water.
-
Do I need a sinker for flounder fishing? Yes, you usually need a sinker or a weighted jig head. Flounder live on the bottom, so your bait must stay down there. A Carolina rig with an egg sinker is one of the most popular setups.
-
Can you catch flounder at night? Yes, flounder can be caught at night. Many people use a technique called gigging, which involves using a light and a spear in shallow water. You can also catch them with traditional gear near lighted docks.
-
What is the best color lure for flounder? White and chartreuse are the most popular colors. These bright colors are easy for the fish to see against the dark, sandy bottom. In clear water, natural colors like brown or silver also work well.
-
How do I tell the difference between a fluke and a flounder? In many regions, the terms are used interchangeably. Generally, “fluke” refers to the Summer Flounder, which has teeth and its eyes on the left side. Winter Flounder have smaller mouths and eyes on the right side.
