How Long Does Fishing Line Last?

Fishing Reels Filled With Fishing Line

Your fishing line is probably one of the most overlooked items in your tackle. Most anglers will replace their hooks, swivels, and even rods before thinking twice about their fishing line. Visually you can spot rust and damage on most of your tackle and gear but fishing line this is not so easy.

So how long does fishing line last? All fishing lines will break down over time if they are used or not. Typically fishing lines will last between 2 – 4 years before they should be replaced. The exact lifespan of fishing lines is affected by different factors such as time, fishing conditions, fishing styles, and storage.

My Personal Rule of Thumb: If you can’t remember the last time you replaced your fishing line then it is time to replace the line.

To understand how you can properly store and maintain your fishing line, we first need to know what causes fishing line to break down in the first place.

How Long Does Fishing Line Last?

How Long Does Monofilament Fishing Line Last?

The lifespan of monofilament fishing lines depends on many different factors, such as:

  • Time
  • Fishing Conditions
  • Fishing Style
  • Storage

Typically, monofilament fishing line can last up to two years, but replacing your monofilament fishing line after one year is recommended.

If you’re fishing line is constantly exposed to sunlight or fish around rocky areas you should expect your mono’s lifespan to be reduced.

How Long Does Fluorocarbon Fishing Line Last?

The lifespan of fluorocarbon fishing lines depends on many different factors, such as:

  • Time
  • Fishing Conditions
  • Fishing Style

Typically, fluorocarbon fishing lines can last up to five years, but replacing your fluorocarbon fishing line after 3 years is recommended.

Excessive loads near or past the line’s pound rating will cause damage to the line causing it to be weaker much faster and reducing its lifespan.

How Long Does Braided Fishing Line Last?

The lifespan of braided fishing lines depends on many different factors, such as:

  • Time
  • Fishing Conditions
  • Fishing Style

Typically, braided fishing lines can last up to seven years, but replacing your braided fishing line after 4 years is recommended.

Excessive loads near or past the line’s pound rating and subject to abrasive conditions such as rocks and sharp teeth can cause line damage thus weakening the line and reducing its lifespan.

How Does Fishing Line Degrade?

How Does Monofilament Fishing Line Degrade:

These lines are manufactured from a type of plastic but like with any plastic they tend to break down when exposed to heat and sunlight.

Monofilament lines can also absorb water which is another factor to causes these lines to break down. Since these lines are able to absorb water then the rate to which these lines degrade is increased when they are used in saltwater.

As the line absorbs saltwater it will also absorb superfine salts particles. Over time as the water in the line evaporates out of the fishing line the superfine particles of salt will be left behind in the line.

The salt particles will affect how the monofilament line will stretch when under load, eventually causing the line to be slightly brittle over a long time. There are various studies that show that monofilament lines can eventually lose up to 20% of its strength.

How Does Fluorocarbon Fishing Line Degrade:

These fishing lines are manufactured from a particular type of plastic generically called “Fluoropolymer“. Because of the different types of plastic used to manufacture the fishing, it offers a completely different set of properties.

Even though these lines are manufactured from plastic, these lines do not degrade the same way like monofilament fishing lines. Fluorocarbon lines do not break down by heat, sunlight, and do not absorb water.

However, unlike the monofilament fishing lines, these lines do not stretch under load, which causes an effect known as “necking” to occur in the fishing line.

Necking is when a material that is under high loads causes the material to stretch. Think about stretching a rubber band where the band becomes thinner as you stretch it. However, unlike the rubber back once the load is released from the fishing line the line will not return to its original shape.

As the fishing line begins to start necking the material becomes progressively weaker. Necking tends to occur at localized weak points such as scratches or external damage on your line.

How Does Braided Fishing Line Degrade

Manufactured from multiple strands that are tightly wounded together using multiple fibres made from Spectra or Micro-Dyneema materials.

When large loads are applied repeatedly over time can cause the braided fibres to become loose which can weaken the fishing line and allows the fishing line to get tangled and easily damaged.

Braided fishing lines have poor abrasion resistance, making the fibres easily damaged if the fishing line rubs against a sharp object. The strength of braided fishing lines comes from ALL the fibres working together but if any of these fibres are damaged or cut through will put more stress on the fibre not damaged.

Properly Storing Your Fishing Line

Keep It Tidy, Keep It Tight: Storing your fishing line for the offseason it is important to keep your fishing line organized. If you are storing loose fishing in a bag or container it can result in the line being damaged. Make sure to keep your line spooled tightly and stored in a well protected to avoid having objects placed on top.

Cool and Dark: Keep your fishing line in a dark and cool spot to protect it from sunlight and heat. You can use a cloth bag to provide protection against scratches and to store reels and spools of line.

Rinse It Off: Rinse off your fishing reel to remove any organic bacteria and salts from the fishing line. Removing these bacteria and salts ensure that the fishing line will not break down when stored. Organic bacteria can break down the fishing line and the salts will cause micro scratches on the line which will reduce its strength.

Rinse-Off The Tackle Box: Storing your fishing line in your tackle box is a very convenient place. However, before you do that you need to make sure you give your tackle box a good wash.

Your tackle box can contain the same bacteria and salts that you just rinsed off from your fishing line. By placing your clean fishing line in a tackle box that could contain these bacteria and salts could result in the fishing line breaking down.

So take the extra 5 minutes to clean out your tackle box. It could save your fishing line.

Examine Your Fishing Line If It Needs Replacing

Before the start of every season, you will need to examine your fishing line to see if you need to replace it.

The easiest way to check if your fishing line is in good condition is what I call the pinch method.

Pinch the fishing line between your thumb and index finger. Slide your hand along the fishing line. The smoother the line feels the better the condition. If you feel kinks or roughness this is generally signs that the line needs to be replaced. Also, visually inspect the line for any discolouration which can be related to damage from excessive sunlight exposure.

If you want to confirm the strength of your fishing line, then the best way is to physically lift weights using the fishing line. There is no one right way to do this. Just pay attention to using a proper knot for your particular setup. Knots are typically a weak point for the fishing line to make sure you use a knot that has good knot strength.

Example, if the fishing line is a 20lb pound test then try to lift 20lbs of weight. If the line snaps then reduce the weight again and try again. Repeat until you find a weight that does not cause the fishing to snap. This will determine your new fishing line test.

Check to see where the line break occurs. If the break occurred at or near a knot then try again using a different knot to see where the break occurs again. If the break occurred away from the knot then the knot was in good condition.

To determine if the line needs replacing after doing these tests depends on your experience and comfort level. Generally speaking, fishing line is one of the cheapest components when fishing. So take the time to play it safe and buy some new line … it will save you tons of headaches.

Dispose of Your Fishing Line

Fishing Line Recycling Station

Not all fishing line can be recycled. Monofilament fishing line is the only fishing line that can be recycled. As a matter of fact, there are a number of programs out there that are geared towards recycling monofilament fishing line.

When recycling monofilament fishing line it must be clean from excessive growth and not made from plant-based material. Organic growth and plant-based material cannot be processed in the recycling plants, therefore, it will not be accepted.

As responsible anglers, we need to do our part to protect the environment and to protect the sport that we all love. So I came up with 3 ways to dispose of your fishing line:

Drop It Off: Once again, monofilament fishing line can be recycled. The best way to dispose of your fishing line is to send it to a recycling depot. Even your local fishing tackle location will be able to handle this for you.

Do not recycle any type of fishing line with your home recycling bin. The chemicals used to manufacture the fishing line cannot be processed in recycling plants designed to handle household products. There is a special recycling process that needs to be done to break down the fishing line properly.

Reuse It: Reusing fishing line is a great way to repurpose the line for other things around the house. Using the line as string or for arts and crafts to making bracelets and necklaces.

Trash: Cut the line into 6-inch segments. Wildlife at the landfill such as birds can use the cut fishing line to build nests. If the segments are too long wildlife can get entangled in the line and if the segments are too short then wildlife will try to consume the line which will not break down in their stomach.

How long does unopened fishing line last?

Fishing line does not come with an expiry date on them. However, if you are properly storing your fishing line then expect your fishing line to last for a while.

  • Monofilament: 1-2 years
  • Fluorocarbon: 2-5 years
  • Braided: 4-7 years

How long does fishing line take to decompose?

The reason why recycling used fishing line is so important is because it takes a long time for fishing line to decompose. Monofilament fishing lines can take up to 500 years before it starts to show evidence of it breaking down. Fluorocarbon and braided lines can take much longer. This is why we need to do our best to recycle and protect the environment.
