Saltwater vs Freshwater Fly Fishing- What’s the Difference

Freshwater fly fishing is by far the most popular type of fly fishing.

My Bestie is a veteran saltwater fly-fisherman and guide, and he can attest to the sport’s rising popularity.

Frequently asked questions address the distinctions between saltwater and freshwater fly fishing.

I’ve learned a great deal about fly-fishing from him, and I’ve gained a great deal of knowledge about this sport.

This is the information I wish to convey in this writing.

The fundamental distinction between saltwater and freshwater fly fishing is in the equipment used, the fishing environment, and the methods utilised to catch the fish. While there is considerable overlap between the two sports, they are essentially unique.

If you’re considering switching from one to the other, understanding these contrasts will save you time, money, and frustration. 

I’ll go into depth about each of these characteristics in this essay, as well as give recommendations on how to prevent frequent blunders.

The majority of people associate fly fishing with going up mountains and casting along little streams.

This statement is not totally accurate. While this is still a widespread practise, the sport of fly-fishing has advanced to the point that individuals are now targeting fish on flies in a number of different bodies of water.

Understanding the fundamental distinctions between freshwater and saltwater habitats can help you prepare for any situation that may arise.

The line and the leader 

( Salt Vs.Fresh)

Saltwater, as you can expect, demands thicker fly lines and stronger leads. This is because the target species is larger, your rod is heavier, and you need to cast larger flies.

Saltwater line and leader.

The bulk of tropical or subtropical holiday resorts are located in seawater. By using a tropical fly line, particularly one tailored for the species being sought, you may avoid tangles and line memory.

While a floating line is most usually used, an intermediate sinking line may be necessary when fishing in deep canals or water deeper than 6 feet.

You should have leader material ranging from 11lb to 80lb test on hand for saltwater situations.

A saltwater leader is typically 9 feet long, although it is not unusual to lengthen it up to 12 feet for frightened fish.

Saltwater leaders feature a heavier butt section, often between 40 and 50 pounds, and taper down to various tippet sizes.

Tippets may be as light as 11lb test for tiny species but are normally in the 14-20lb range for larger species.

Class leaders will include bite portions for bigger species, such as tarpon.

These bite parts will weigh between 31 lb and 80 lb. Tippet and bite sizes will be modified to account for water clarity and the leader shyness of the target species.

Freshwater line and leader

The bulk of freshwater fly fishing takes place in colder waters. Included in this group are alpine streams, Alaskan rivers, and the Great Lakes. In these instances, it makes sense to utilise cold-water fly lines.

Cold-water fly lines are often softer, as they do not stiffen or lose memory in cold water.

Freshwater lines, like saltwater lines, can be purchased to target certain fish species. For the great majority of freshwater fishing, a floating line is essential. You’ll require an intermediate or sink-tip line when casting huge streamer flies to deeper fish.

Trout, particularly wild ones, have a remarkable ability to see. This requires a large reduction in the size of the leaders. Tippet sizes of 3x (8lb), 4x (6lb), and even 8x are relatively uncommon (1.75lb).

Additionally, freshwater leads tend to be longer in length. A freshwater leader is typically 10′ in length, but can be as long as 15′. When targeting more active freshwater species, such as bass, a shorter leader of 7.5′ might be employed.

Additionally, the diameter of the leader is proportionate to the size of the flies cast.

Due of their similarity to insects, freshwater flies are generally smaller in size and hence more readily thrown using thinner leader material.

Freshwater fishing tactics vary considerably, necessitating the usage of a unique leader for each application.


We’ll go into great detail on the many types of flies because there are so many of them. In the end, freshwater and saltwater flies are fundamentally different because of the bait accessible in their respective environments.

Insects and tiny baitfish are the principal food sources in freshwater settings. There are several predator species that are constantly examining the ground for insects that have landed. These insects include, but are not limited to, mayflies, caddis, drakes, grasshoppers, and ants.

Trout fishing flies, for example, imitate these insects and are thrown during the times when they are most active. Due of their small size, the flies employed for these insects must likewise be small.

Freshwater fish have a built-in tendency to eat bigger prey as they grow in size. Sculpins and leeches have been added to the menu at the restaurant. If you want to catch fish, you’ll need to use bigger freshwater flies such as streamers.

As humans move to saltwater areas, our food sources will shift. Prey in seawater includes crabs, shrimp, and other crustaceans.

Saltwater flies tend to be bigger in the wild because they feed on larger food than insects. In order to catch a larger prey species, you may use a quarter-sized crab or an 8-inch baitfish.

When it comes to fishing, it is always best to match the flies to the fish. Throwing flies that look like local bait will help you catch more fish.

Distinction between Rod and Reel

Freshwater fly fishing will be dominated by species between 1 and 15 pounds. In addition to brown trout, rainbow and Brook Trout are also included. 

It is best to use a fly rod that is between 4wt and 7wt to capture these species.

Unsealed drag mechanisms are common on reels that are matched to the weight of the rod. 

In general, freshwater reels are less expensive than saltwater reels because of the lesser quality of the construction components and the lower demands on the drag. This can be related to their incapability to deal with freshwater organisms.

When compared to freshwater game fish, saltwater species tend to be bigger. Fly gear will have to be beefed up to handle this situation.

Saltwater fish such as tarpon, permit, striped bass, bonefish, and redfish are all prevalent. 

The weight of this fish can range from 3 to 200 pounds. Due to the size and fighting ability of these fish, fly rods ranging from an 8wt to a 12wt will be necessary.

Drag systems must be sturdy and sealed because reels will be utilised most of the time. Saltwater anglers place a far higher value on reel quality than those fishing freshwater. Use a saltwater resistant reel while making the conversion from freshwater fishing to saltwater fishing.

Wherever gear overlaps, there is a problem.

At times, the equipment that is being utilised is going to be employed in conjunction with each other. 

Freshwater anglers who want to catch larger fish like steelhead or salmon will use the same type of gear as those who are targeting smaller saltwater species like redfish and bonefish.

Those who fish in saltwater with a 6 or 7-weight rod and reel for smaller fish may use what they’ve learned to catching medium to large freshwater species with the same gear they use in the sea.

What are the distinctions between freshwater and saltwater environments?

Area of Freshwater

There is a freshwater body of water nearby for most fisherman. Rivers, lakes, and other waterways are included in this category.

When fly fishing in these places, you’ll encounter two recurring themes:

Fish naturally congregate in these tiny waterways.
Making a fly cast isn’t always the best option.

Compared to an ocean or a sea, these places are little in comparison. Since these fish prefer to stay in the same places and follow similar eating routines, they tend to stick to the same habits.

Despite the fact that this makes it simpler for freshwater species to be targeted, it increases their vulnerability to overfishing. It is impossible for the fish to breed and reproduce quickly due of the pressure and harvesting of the fish.

Hence the requirement for freshwater storage lakes and streams by animal management authorities.

You’ll have to put in more effort and be more discrete if you want to locate native trout species in the wild. For freshwater anglers, catching a wild fish is like finding the “holy grail.” As a result, anglers have had to hike greater distances, up higher hillsides, or go deeper into the forest to find undisturbed fish.

As you may guess, getting to these streams, rivers, or hidden lakes can be dangerous. Looking at this terrain, a decent pair of hiking shoes and an organised supply bag are essential.

When you venture into these locations, you’ll be able to discover that fish in some tricky conditions. To show off the fly, it isn’t unusual for your fly to dangle from a cliff.

You’ll also notice that most of these locations don’t allow for proper casts because of the trees and other obstructions behind you. This is a major problem in the realm of freshwater fishing. If you know how to load the rod with water and do various casts, you’ll be successful in these scenarios.

Freshwater fishing isn’t for everyone who ventures into the woods. On larger lakes and rivers, boats are used. Many rivers offer guided rafting trips from the banks, where a guide takes you down the river with them at your side.

When fishing from a boat, you may throw farther and cover more land in less time. If you’re new to fly-fishing or aren’t familiar with the region, I highly recommend hiring a guide.

The environment of salt water

The quantity of available space varies dramatically between freshwater and saltwater habitats. 

These places are usually huge and need more time and effort due to the difficulty in locating fish in those areas. 

There are no restrictions on where you may cast in these places, however they aren’t usually viewed as other freshwater fishing obstacles.

It’s not uncommon for fishing to be tough in estuaries, flats, and bays. 

You’ll be able to explore more regions if you have a boat. The boat’s height also makes it easier to view fish at a distance.

When fishing in these wide open spaces, you’re more at risk from wind. Learn to cast directly into strong gusts when fishing in saltwater.

In fact, the best way to deal with certain types of skittish fish is to approach them with wind. Too much calm will prevent you from reaching the distance.

Finally, with the presence of saltwater, tides will be present. 

A single hour’s difference in the salinity of a river or lake’s water level might last months or even years depending on rainfall.

Navigation is made more difficult by the ebb and flow of the tides, which also determine where fish will be found. 

Fish in a particular flat region tend to travel when the tide goes out and back in.. Saltwater anglers now have even another useful variable at their disposal.

Changing your methods – Fresh vs. Salt
Techniques for freshwater

It is necessary to adapt your strategy while transitioning from one to the other because of the different environments. The main difference between fresh and salt water fly fishing is in the casting and presentation of the fly.

Moving water will be the primary location for freshwater fishing in the near future. Rocks and other structures create eddies in which freshwater creatures tend to cluster.

Fish can preserve energy while waiting for prey to flush down a river or creek by resting in an eddy. Fish typically scan the surface of the water for a variety of floating insects while they wait.

It is important that the fly shown to the audience seems as natural as possible. Changing the fly’s downstream movement will alert the fish to the notion that anything is amiss.

The fly will drift at an abnormal velocity or angle as a result of the drag caused by the fly line in the water. In these cases, a repair is required.

In fly fishing, what is a mend?

An upstream mend is when a bow is placed into the fly line to lessen drag. As a result, the fly is allowed to float naturally downstream. 

When a fly drifts naturally, it’s known as a dead drift.

When fishing with dry flies or nymphs, you may want to try dead drifting. This style of fishing does not need you to move the fly at all. 

The drift takes care of the majority of the effort, making it an ideal method for those just starting out in the sport of fly fishing.

For example, while fishing streamers, the fly will be twitched more often. 

In order to induce movement, you must manually strip the fly.

With a double haul cast, streamers are cast in the same manner as saltwater flies. 

If you’re using a streamer fly, allow it to sink for a few seconds after you land it by adding a mend to your line.

Slowly proceed to remove the fly from the fly box. 

The fly should be able to move freely in the current during streamer fishing. If a drift has stopped, this is the exact opposite.

The swing’s baitfish impersonation is regularly devoured by hungry fish. It’s hard to beat a streamer strike while freshwater fishing, and it’s a particular favourite of mine. 

Switching to streamers when fish aren’t aggressively eating dries generally results in a bite.

Casting in freshwater

Freshwater casting is more of an art form than saltwater casting, which necessitates the use of physical force to be successful. 

According to the preceding paragraph, casting movement is usually restricted, forcing some ingenious manoeuvring.

You will be able to present the fly in regions where backcasting is not feasible if you are familiar with how to conduct a simple roll cast.

How is roll casting defined?

In order to allow the line to spread out at your feet, a roll cast includes making the letter “D” with your rod and line above the surface of water. 

The straight line of the letter “D” symbolises your rod, while the curved section indicates the construction of the line itself.

Once you’ve gotten into position, make a forwards cast. Due to the drag caused by the line in the water, a load is placed on the rod, allowing the line to roll out in front of you. 

This is how the phrase “Roll Cast” came to be used in this context.

Being able to roll cast will save you a great deal of time and irritation when you’re casting. Fresh water fishing, on the other hand, does not demand lengthy casts, thus any capacity to get the fly into the water is typically beneficial.

Casting in the steeple

The steeple cast is another popular variation. 

While this cast is occasionally used in salt water on windy days, it is more prevalent in freshwater.

The steeple cast is performed by starting in a horizontal back cast and then raising your arm straight up in the air. You then complete the forwards cast normally from this position.

This cast is intended to lift the line straight up in the air on the back cast in order to avoid any trees or other snags behind. While this cast is effective, I must admit that proficiency requires considerable practise.

In either scenario, when a fish strikes, the hook is set by lifting the rod straight up in the air. 

This is known as the “Trout set.” When fishing in freshwater, there is frequently slack in the line, which can be quickly removed by lifting the rod tip when setting the hook.

Learning to roll cast and mend is the quickest way to gain an immediate advantage when freshwater fishing.

 Salt water methods:

Swimming in saltwater requires that you maintain a safe distance from the water. 

Due to the fact that freshwater fishermen do not have adequate distance in their cast, they have a tough time casting in saltwater.

When compared to freshwater fish, which may remain immobile for lengthy periods of time, saltwater fish can be found continually moving.

Their natural predators, like as sharks, are continuously on the prowl, and they have a boat-like appearance, which makes them seem even more dangerous.

 This causes them to become more agitated and more prone to escape the scene. To put it another way, your ability to get near to them is highly uncommon.

In fly fishing, what exactly is double hauling?

Knowing how to double haul will be the most important skill to have when fly casting in saltwater.

Double hauling is a technique in which you pull on the line with your non-casting hand in order to increase the load on the back and forwards casts. 

This additional load enables you to make more casts and punch the cast into the wind, allowing you to increase your efficiency.

When presenting a fly in saltwater, it is your responsibility to ensure that the fly is alive and swimming around. 

Rather than being startled by something dead drifting across their path, predators in the saltwater are accustomed to fleeing bait. Different types of flies will necessitate the use of different stripping methods.

A short tick strip is usually used when fishing a crustacean pattern, such as shrimp or crab, because of the short ticks. 

This is intended to give the impression that a shrimp is popping or that a crab is shuffling across the bottom.

When presenting these flies to a fish, the angle at which they are presented will be critical. Unlike in the wild, where prey is unlikely to swim towards a predator, making a shot that allows you to cross a fish or pull the fly away from the fish will frequently result in an eat.

When you strip a fly towards a fish, this is referred to as a negative angle, and it should be avoided if at all possible.

Fishing bait patterns are created by using a constant strip to simulate the movement of a swimming fish.

A long, steady strip should be used for this strip, with the speed of the strip increasing as the fish locks onto it.

Several anglers will place the rod under their arm and use both hands, one after the other, to strip the fly more frequently in order to make the fly swim more naturally. 

The double hand strip is the term used to describe this technique, which is most commonly used when tarpon fishing.

When you get a strike while fishing in saltwater, your natural instinct will be to lift the rod and set the hook right away. This should be avoided at all costs, and stripping should continue.

It is always necessary to continue stripping until the fish is completely tight. A technique known as ” Strip setting” is used to accomplish this. The majority of the time, lifting your rod tip will result in a missed fish.

Common mistakes when transitioning between Fresh and Saltwater

When migrating from freshwater to saltwater, there are three frequent mistakes that fishermen make that should be avoided.

After catching a fish, you should adjust your “set.”

Nothing will make your guide or fishing companion more enraged than witnessing you miss a fish when you should have been strip setting rather than trout setting, or vice versa, when you should have been strip setting rather than trout setting.

By making a deliberate effort to break free from a bad habit in the current moment, you will be less likely to make the same mistake again. Do not berate yourself; this is something that occurs to anyone.

Although it may seem counter-intuitive, consistently reminding oneself and thinking through the procedure will almost always result in less snafus.

The fly moves too little or too much, depending on the situation.

Those who fish saltwater will benefit from this tip more than those who fish freshwater. This is something I am particularly guilty of. In order to make the transition from a saltwater to a freshwater habitat, the natural impulse is to strip the fly rather than letting it float naturally.

Just before you start fishing, take a time to look around you, paying close attention to how the bait moves in the water. By imitating this behaviour, you can enhance your chances of being bitten significantly.

When fishing in unfamiliar locations, there is a lot of uncertainty.

The internet is a fantastic piece of technology. It is jam-packed with knowledge on virtually every subject conceivable. Make use of it to familiarise yourself with a certain place or kind of fishing before you travel there to fish.

Although you will be fishing with a guide, it is a good idea to become familiar with the fishery and the strategies you will be applying before you begin fishing. If you don’t know what you’re doing, don’t expect the guide to lead you through the process.

If you’re not sure what you should look into, talk to a local fly shop or guide. Any bit of local expertise will be beneficial to your campaign.
