How to Catch Blue Cats

To catch big blue catfish, or blue cats, it’s crucial to understand their behavior, habits, and preferred environments. Blue catfish are opportunistic feeders, often hunting in deeper waters, near river channels, drop-offs, and submerged structures. They are also known to have large home ranges and tend to be more active at night, making fishing for them a little more challenging, but highly rewarding.

Types of Catfish and Identification

Catfish are a diverse group of fish, with over 3,000 species worldwide. In North America, anglers primarily target three main species: Blue Catfish, Channel Catfish, and Flathead Catfish. Each species has distinct physical characteristics that make them easily identifiable.

• Blue Catfish: Known for their distinctive blue-gray color, blue catfish have a flat anal fin with 30-35 rays. These big fish can grow up to a staggering 143 pounds and are typically found in deeper waters of lakes and main river sections. Their impressive size and strength make them a prized catch for many anglers.

• Channel Catfish: Channel catfish are characterized by their olive-brown to gray color and a curved anal fin with 25-28 rays. They usually grow up to 20 pounds and inhabit a wide range of waters, including lakes, rivers, and streams. Their adaptability and abundance make them a popular target for catfish fishing.

• Flathead Catfish: Flathead catfish are easily recognized by their flat tail and underbite, along with a brown or yellowish-brown color. These big cats can reach up to 100 pounds and prefer rivers and streams with rocky or sandy bottoms. Their unique appearance and size make them a fascinating species for anglers to pursue.

Habitat Preferences

• Deep Water: Blue catfish prefer deeper waters where they can find both shelter and food. They are often found in the lower parts of rivers and lakes, particularly around channels, deep holes, and submerged structures like fallen trees and rocks. To effectively catch blue catfish, target specific structures in lakes and focus on key locations like bends and deep holes in rivers to improve fishing success.

• Tidal Influence: In rivers, blue catfish can be heavily influenced by tidal movements, especially in the spring and fall. The movement of the tide can bring in fresh bait and increase their feeding activity.

Feeding Behavior and Catfish Bait

• Night Feeders: While blue catfish can be caught during the day, they are often most active at night when they come out to hunt. This is especially true in the warmer months when they can be found feeding closer to the surface at night.

• Bottom Feeders: Blue catfish primarily feed on fish, crustaceans, and other aquatic animals found near the bottom of their habitat. They have an exceptional sense of smell and are capable of detecting bait from great distances. Using fresh, native bait fish like threadfin shad or gizzard shad can significantly increase your chances of success, as it matches the natural forage available in their environment.

Blue Catfish Social Structure

Blue catfish are not solitary creatures; they often gather in large schools, displaying a complex social structure. These fish are known to form long-term pair bonds, with males and females working together to build and defend their nests. In the wild, blue catfish exhibit intricate social hierarchies, where dominant individuals lead subordinate fish to food sources and shelter. This social behavior not only aids in their survival but also makes catching catfish a more intriguing challenge for anglers.

Blue Catfish Migration Patterns

Blue catfish are migratory fish, moving between different habitats throughout the year. In the spring, they migrate upstream to spawn in shallow waters, taking advantage of the warmer temperatures and abundant food supply. As fall approaches, they move downstream to deeper waters to overwinter, seeking the stability and protection these areas offer. During the summer, blue catfish can be found in a variety of habitats, including lakes, rivers, and streams, making them accessible to anglers using different catfish fishing techniques.

Blue Catfish Communication

Blue catfish have a sophisticated communication system that includes sound, vibration, and visual cues. They use their lateral line to detect vibrations in the water, which helps them locate prey and avoid predators. During the spawning season, blue catfish use sound to communicate with each other, coordinating their movements and activities. This ability to communicate effectively is a key factor in their success as a species and adds another layer of complexity to the challenge of catching these big fish.

Advanced Gear for Catching Big Blue Catfish

Catching big blue catfish requires catfish rods and other heavy-duty equipment capable of handling their size and strength. Your gear should be able to withstand long runs and powerful surges.

Catfish Rods and Reel

• Rod: When selecting catfish rods for big blue catfish, a 7-10 foot, heavy-action rod is ideal. The rod should be strong enough to handle a large fish, but sensitive enough to detect light bites, especially when using live or cut bait.

• Reel: Choose a high-quality reel with a strong drag system and a high line capacity. A baitcaster or a large spinning reel with at least 200 yards of 30-50 lb test braided line will give you the strength needed for big catfish.

Fishing Line

• Braided Line: Braided fishing line is preferred for blue catfish due to its strength and sensitivity. It has a smaller diameter than monofilament, allowing for longer casts and better sensitivity to bites.

• Leader Line: Use a heavy fluorocarbon leader (50-80 lb test) to avoid abrasion from sharp teeth, rocks, or submerged structures. Fluorocarbon also has low visibility in the water, which is ideal when fishing for wary fish like big blue catfish.

Hooks

• Circle Hooks: Circle hooks in the 6/0 to 10/0 range are ideal for blue catfish. They are designed to hook fish in the corner of the mouth, reducing the risk of deep-hooking and increasing the chances of a successful catch-and-release.

• J-Hooks: Larger J-hooks can be used for heavier baits, but circle hooks are often preferred for their reliability.

Weight and Sinker

Blue catfish are bottom feeders, so using the right weight or sinker to keep your bait near the bottom is critical. A 3-8 oz egg sinker or no-roll sinker works well depending on the current and water depth.

Advanced Techniques for Catching Big Blue Catfish

Once you have the right gear, employing the right fishing techniques to catch catfish is key to landing big blue catfish. These fish are smart and can be elusive, requiring a strategic approach.

1. Night Fishing

Big blue catfish are more active at night, particularly during the warmer months. The darkness and cooler water temperatures make them more willing to feed near the surface or closer to the shoreline.

• How to Do It: Fish during the evening and through the night, especially during new or full moons when the fish are more likely to be feeding actively. Use lights or glow sticks to attract baitfish and create a feeding zone that attracts blue catfish.

• Tip: For successful catching fish, set up around areas with deep holes, drop-offs, or submerged structures, where catfish are likely to be feeding at night. Selecting proper bait and understanding fishing locations are crucial for increasing your chances.

2. Drifting with Cut Bait

Drifting is an effective technique for covering more ground and targeting big blue catfish. By drifting bait, you can find where the fish are feeding and adjust your position accordingly.

• How to Do It: To catch fish effectively, use cut bait, such as shad or herring, and drift it across deeper parts of the river or lake, keeping the bait near the bottom. You can attach a slip sinker to your line, allowing the bait to flow naturally with the current while remaining close to the bottom.

• Tip: Pay attention to your depth sounder to identify where the fish are located. Drift across different depths to find the optimal feeding zone.

3. Anchored Fishing with Live Bait

When you know where blue catfish are likely to be, anchoring in the right location and using live bait is a powerful method to target big fish.

• How to Do It: Use catfish bait like large shad, skipjack, or live bluegill. Anchor your boat or set up on the bank in areas with deeper channels or near submerged structures. Cast the live bait into the current or just off the bottom to attract the fish.

• Tip: Use a large circle hook to ensure a solid hookset when the catfish strikes. Make sure your bait is lively and positioned where the catfish are most likely to hunt.

4. Targeting the Right Structure

Big blue catfish are often found near structure, where they can ambush prey. Look for submerged structures such as fallen trees, rocky outcroppings, or deep river channels where catfish can hide and feed.

• How to Do It: Cast your bait near submerged structures or set up your rig to drift through areas with structures at the bottom. Catfish will often stay close to these structures to avoid predators and hunt for prey.

• Tip: Focus on areas with both deep water and structure, such as river bends, submerged islands, or drop-offs. These locations provide a mix of food and shelter for blue catfish. To target bigger fish, use appropriate bait that attracts larger catfish, as they shift from scavenging to actively hunting for larger prey.

5. Using Tackle and Rigging for Heavy Fish

For blue catfish, especially larger ones, it’s important to use tackle that can handle the weight and power of these fish. Use stronger rods, reels, and line to ensure your gear holds up during the fight. While stink bait is effective for catching smaller Channel Catfish, more experienced anglers targeting larger species should opt for meatier options like fresh or live bait.

• How to Do It: Use a heavy-duty rod with a strong backbone, a reel with a high drag system, and a 50-80 lb test braided line. Set up your rig with a slip sinker, a circle hook, and a heavy fluorocarbon leader to minimize the risk of line breakage.

• Tip: When reeling in a big catfish, let it run if needed, but keep tension on the line to avoid slack. Once the fish tires, gently reel it in and secure it with a net.

6. Fishing During Spawning Seasons

Blue catfish are known to spawn during warmer months, particularly in the late spring to early summer. During this time, they are more likely to be found near their spawning areas, which are often shallow and rich in food.

• How to Do It: Fish during the spawning season when blue catfish are more concentrated. Focus on shallow flats or areas near the river’s mouth or tributaries, where the fish come to spawn.

• Tip: Use live bait or fresh cut bait during spawning to attract fish to your area, and focus on early mornings and evenings when the fish are most active.
