Catching trout is a difficult task since this type of fish is fast and one can spook them easily. It’s a great relief for a fisherman when they manage to hook trout. You can find this freshwater fish in rivers, ponds, lakes, and streams. The Rainbow, Brown, and Brook are the most common types of trout caught by fishing enthusiasts.

Therefore, you must equip yourself with the right gear before going out to fish for trout. Among the equipment you need are a good reel, rod, and line. While there is a wide variety of fishing lines available on the market, not all are ideal for catching trout. This guide and review will help you select the best fishing line for trout.

What to Look Out for When Getting the Best Fishing Line for Trout

When looking for the best fishing line for trout, you need to take into consideration several important factors. The critical factors include weight, size, material, durability, memory, and color.

Material Used

The different types of materials used to make fishing lines deliver different performance and capabilities. Some of the commonly used fishing line materials include monofilament, fluorocarbon, braided, and lead core. Monofilament fishing lines are versatile and less costly. They also come in a variety of colors but have a high memory, meaning they can bend easily.

Fluorocarbon fishing lines are smooth and durable. The fact that they can resist abrasion means they can sustain any damages that come from scraping the seafloor.

The strongest material ideal for spinning reels is the braided fishing line. Due to its low memory, this type of fishing line doesn’t kink or curl up. However, it will cost you more to acquire the braided fishing line.

The lead core fishing line is suitable for deep-sea or lake fishing but not ideal for angling in streams and rivers. This material features a lead core at its center making it heavy and very sturdy.

Weight and Size

There are different thicknesses available for fishing lines so that they can handle a wide range of weight when trout angling. The fishing line’s size refers to its diameter and this measurement often comes in millimeters.

The diameter of the fishing line will affect its visibility, casting ability, and depth. Thinner lines are ideal since they have reduced visibility to fish, giving the bait a more realistic look.

To improve the durability of your fishing line, it's vital to select a heavy one. A heavy line should come with heavier bait. A lighter line will be more suitable if durability isn’t something you’re worried about.


The fishing line color will influence its visibility to the fish once you cast it. You should be able to see the fishing line move when you successfully hook trout. Nonetheless, the fishing line mustn't be visible to the fish as it may spook them.

The location and time of fishing are key to choosing the type of fishing line color you select. When fishing in clear water, a low visibility color will be the best option. Alternatively, brightly colored fishing lines are suitable when fishing at night or in low light conditions.

Fishing Line Memory

The memory of a fishing line refers to its ability to retain its shape when wound in the reel. With lines having several kinks and curls, there’s a significant effect on the overall length. Selecting a low memory fishing line will depend on the location of fishing.

A low memory fishing line will provide the longest line possible. This means that a low memory fishing line won’t be ideal for trout angling in rivers and streams. However, in a lake or sea, low memory fishing lines will be very important if you want to catch trout.

Durability and Sensitivity of the Fishing Line

These two features are different but vital in determining the quality of the fishing line. A great indicator of the durability of your fishing line is in its strength. A very strong fishing line won’t snap under pressure. Thick lines won’t succumb to the strains of angling heavy trout from the water.

How much you feel the line when fishing will determine its sensitivity. A very sensitive line will allow you to feel even the slightest pull, improving your fishing experience. Such lines will help you to increase the ratio of catching fish. Conversely, lines that aren’t very sensitive will reduce the chance of getting some catch.

This fishing line sinks faster than a similar fishing line, is sturdy and very flexible when it comes to the range and tensile strength. It's also resistant to abrasion meaning that it isn't easily damaged when it collides with hard objects in the water.

Depending on your personal preferences, you can use this line as the mainline. The small diameter of this fluorocarbon line makes it perfect for angling trout regardless of the fishing season. It’s also quite affordable compared to other fluorocarbon fishing lines. Nonetheless, the silicone comes off easily as pointed out by many anglers.

Choosing the Best Fishing Line for Trout

As mentioned above, there are different types of materials used to make fishing lines. These include monofilament, fluorocarbon, lead core, and braided fishing lines. These materials differ in terms of strength, memory, and durability. The fluorocarbon fishing line is the most popular fishing line for trout for several reasons.

Since trout are very shy fish and highly visible fishing lines will spook them easily. These fish also have better eyesight than any other fish and can see ultraviolet frequencies. Fluorocarbon fishing lines are ideal since they're hard to see when underwater making it hard for trout to see.

Due to their amazing sight, trout can spot fishing lines easily. Monofilament fishing lines won’t be suitable for angling trout for this reason. Trout can view different directions at the same time making it difficult to use highly visible fishing lines.

Why Fluorocarbon Fishing Line is Better for Trout Fishing

Most experienced anglers recommend fluorocarbon fishing lines since they work better than the other types of fishing lines. As aforementioned, trout are very shy fish and will take flight as soon as they see the fishing line. The fluorocarbon is transparent and will increase your odds of catching more trout.

Can Trout Spot Fishing Line?

Trout have monocular and binocular vision meaning their eyes work independently. They can view the opposite direction while swimming. Their advanced vision makes it easier for them to spot a fishing line, regardless of the type of bait you’ve placed.

Select a transparent line to ensure that you won’t spook the trout easily. Most fishing lines made for freshwater angling are transparent. Along with the appropriate bait, you can catch as many trout as you want.


It shouldn’t be an uphill task for one to choose the best fishing line for trout. Each fishing line has specific features that make it stand out from the rest. The fishing lines have different memories, sizes, strength, material, and durability. Understanding these features will allow you to select the best fishing line for catching trout.

It’s also important to understand the type of fish you intend to catch. Trout fish are shy and have amazing vision. Therefore, the fishing line you select should be virtually invisible to help improve your catch. That said, the fluorocarbon fishing line is the most suitable for catching trout.
