Guide: Choosing the Right Fishing Flies for Bonefish
When planning a tropical fishing trip to the flats, where bonefish often move close to the bottom, the weight of the fly plays a crucial role. It's not just about patterns, but about how quickly the fly sinks. The correct weight determines if the fish has time to see the fly and if the presentation feels natural.
Here we go through three weight classes that should always be in your fly box for a serious tropical fishing adventure.
1. Light Weight – for Really Shallow Water
On very shallow flats, when fish are skittish, flies with minimal weight are suitable. They sink slowly and land softly, reducing the risk of scaring the fish.
- Choose flies with small bead chain eyes or plastic eyes
- Land the fly gently
- Preferably tie flies with a wider profile so they don't splash on the surface
2. Medium Weight – Balance for Normal-Depth Flats
For flats about 40–100 cm deep, especially with a bit of water movement, medium-weight flies are suitable. The goal is for the fly to quickly reach the bottom and stay there during calm retrieves.
- Cast in front of the fish and let the fly sink
- Use slow retrieves with pauses
- Match color with the bottom: sand, grass, or light mud
3. Heavy Weight – When Fishing Deeper Flats
When the water is deeper or when several bonefish are hunting simultaneously, a heavier fly with lead or brass eyes is needed. It sinks quickly to the correct level and stays there during retrieves.
- Give the fly a few seconds to sink before you start retrieving
- Aim for edges and transitions on the flats
- Preferably make slightly longer casts to avoid scaring the fish
How to Build Your Bonefish Box
A good basic setup is to have at least three to four flies in each weight category. Always choose hooks and materials that can withstand saltwater.
| Weight | Eyes | Rec. hook size |
|---|---|---|
| Light | Plastic or small bead chains | #6–#8 |
| Medium | Larger bead chains or light metal | #4–#6 |
| Heavy | Lead or brass | #4–#6 |
Why Weight is Important
Bonefish often feed near the bottom. A fly therefore needs to sink to the correct level and move naturally. If the fly is too light, it floats above the fish. If it's too heavy, it can land hard and scare the fish away.
- Better presentation on the bottom
- Clear contact during retrieves
- Less risk of the fish detecting the line
Ready for Your Tropical Fishing Adventure?
When you travel abroad for a fishing trip and target bonefish, variation in fly weights is at least as important as patterns and materials. Adapt the fly to depth, bottom, and current to increase your chances of a bite.
