Status: Available (557 KB) Download

As a lifelong angler and outdoor writer, I’ve spent countless hours on the water, and I can tell you one thing: when it comes to attracting fish, especially panfish like perch and crappie, water dogs bait and leeches for bait consistently deliver. Whether you call them water dogs, leeches, or simply live bait, understanding how to effectively use these wriggling wonders can dramatically improve your fishing success. This guide will cover everything from finding and catching your own live bait leeches to keeping leeches alive and the best techniques for fishing with leeches. We’ll even explore homemade leech traps and where to buy leeches for fishing if you prefer not to harvest them yourself.

Why Use Water Dogs and Leeches as Bait?

Leeches and water dogs (which are actually the larval stage of certain aquatic insects, often horsefly or deer fly larvae) are incredibly effective because of their natural movement and scent. Fish are instinctively drawn to these creatures. Here’s a breakdown of why they work so well:

  • Natural Presentation: Their wriggling action mimics the movement of other aquatic insects and small invertebrates that fish feed on.
  • Scent: Leeches and water dogs release a scent that attracts fish from a distance.
  • Versatility: They can be used in a variety of fishing techniques, from simple hook presentations to slip bobber rigs.
  • Species Specificity: They are particularly effective for panfish (perch, crappie, bluegill), but also work well for bass, walleye, and even catfish.

Catching Your Own: How to Trap Leeches and Water Dogs

While you can buy live leeches near me at most bait shops, catching your own can be a rewarding and cost-effective experience. Here's how to build a homemade leech trap and find waterdog fish bait:

Building a Simple Leech Trap

A simple leech trap can be made from a plastic bottle or a small container. Here’s what you’ll need:

  • A plastic bottle (2-liter soda bottle works well) or a small plastic container.
  • Raw liver (beef or pork) – this is the primary attractant.
  • Small holes drilled in the sides of the container.
  • Weight to keep the trap submerged (rocks or a small weight).

Instructions:

  1. Drill small holes around the sides of the bottle/container, allowing water to circulate but preventing leeches from escaping easily.
  2. Place a small amount of raw liver inside the trap.
  3. Weight the trap and submerge it in a slow-moving stream, pond, or lake, preferably near vegetation or muddy bottoms.
  4. Check the trap after 24-48 hours.

Important Note: Always check local regulations regarding bait harvesting. Some areas may have restrictions. (National Park Service)

Finding and Collecting Water Dogs

How to catch mud leeches, or water dogs, is a bit different. They typically burrow in muddy or silty bottoms. You can find them by feeling around with your feet (wear water shoes!) or using a long-handled tool to stir up the sediment. They’ll often cling to your feet or the tool. Look for areas with decaying vegetation, as they feed on organic matter.

Keeping Leeches and Water Dogs Alive

Successfully keeping leeches alive is crucial for maximizing their effectiveness. Here’s a detailed guide:

Water Quality

Leeches and water dogs need clean, cool, and oxygenated water. Here’s what to do:

  • Temperature: Keep the water between 50-65°F (10-18°C). Avoid direct sunlight.
  • Aeration: Use an air pump and air stone (like those used in aquariums) to provide oxygen. Change the water frequently.
  • Water Changes: Change 50% of the water every 1-2 days. Use dechlorinated water.
  • Container: A plastic container with a lid (with air holes) works well. Avoid metal containers.

Feeding

Leeches don’t need to be fed frequently, especially if you’re using them within a few days. However, if you need to keep them for a longer period, you can offer small pieces of liver or fish. Water dogs benefit from a bit of decaying vegetation in their water.

Storage Tips

Keeping leeches alive for extended periods requires diligence. Here are some extra tips:

  • Avoid overcrowding.
  • Remove any dead leeches immediately.
  • Keep the container in a cool, dark place.

Fishing Techniques with Leeches and Water Dogs

Now that you have your leeches fishing bait, let’s talk about how to use them effectively. Here are some popular techniques:

Slip Bobber Rig

This is a classic and highly effective method for panfish. The slip bobber allows you to adjust the depth of your bait, targeting fish at various levels. Use a small hook (size 6-10) and thread the leech or water dog onto the hook, leaving a small portion exposed.

Jigging

Attach a leech or water dog to a small jig head (1/32 oz - 1/16 oz) and jig it slowly near weed beds or submerged structure. This technique is great for bass and crappie.

Hook and Split Shot

A simple but effective rig. Use a small hook, add a few split shot weights to get the bait down to the desired depth, and fish it slowly along the bottom.

Leech on a Spinner

Thread a leech onto a spinnerbait or in-line spinner for added attraction. This is a great way to cover more water and target active fish.

How Many Leeches in a Pound?

This is a common question! The number of leeches in a pound varies depending on the size of the leeches. Generally, you can expect around 300-500 small to medium-sized leeches per pound. Larger leeches will weigh more, so you’ll have fewer per pound.

Where to Buy Leeches for Fishing

If you don’t want to catch your own, there are plenty of places to where to buy leeches for fishing:

  • Local Bait Shops: This is the most convenient option.
  • Sporting Goods Stores: Stores like Bass Pro Shops and Cabela’s typically carry live bait.
  • Online Retailers: Several online retailers ship live bait, but shipping costs can be significant.

Raising Leeches: A More Involved Option

How to raise leeches is a complex process that requires specialized knowledge and equipment. It involves creating a controlled environment with specific water parameters and providing a suitable food source. It’s generally not recommended for beginners. The USDA Forest Service provides information on aquatic ecosystems, which can be helpful in understanding leech habitats: USDA Forest Service

Leeches as Bait: Best Perch Trap Bait

When it comes to best perch trap bait, leeches are consistently ranked among the top choices. Their scent and movement are irresistible to perch. Combine leeches with a small amount of cornmeal or fish attractant to further enhance the trap’s effectiveness.

Safety and Ethical Considerations

Always practice responsible bait harvesting and handling. Be mindful of the environment and avoid disturbing sensitive habitats. Follow all local regulations and guidelines. Leave No Trace principles apply to bait collection as well. (Leave No Trace)

Using water dogs bait and leeches for bait is a time-honored tradition among anglers. By following the tips and techniques outlined in this guide, you’ll be well-equipped to maximize your fishing success and enjoy the thrill of catching fish with these natural and effective baits.
