Catch and Release Fishing Practice: What is it?

The fish you catch is yours to keep. Most people don’t go so far as to remove hooks and gaffs from their fish. So that means, most likely, that those fish are caught legally.

That being said, you should always ask yourself, “Do I want to eat this fish?” When you do so, you’re making the decision to release the fish back into the wild.

The problem is that some people believe that catching fish is the same as killing fish or that it doesn’t matter if you let them go or not. These people may not be aware that there’s a growing movement to protect fish populations from overfishing.

When you’re out on the lake or ocean, you should consider the best catch and release fishing practices. If you choose not to follow these best practices, you could likely break the law.

The following guidelines can help you determine if you’re allowed to keep a fish and, if so, what to do with it.

What is catch and release fishing?

“Catch and release” is a term used to describe an angler’s approach to fish management. It’s a practice of releasing hooked fish rather than killing them.

In the sport of fishing, this practice is commonly referred to as “catch and release.” A catch and release fishing practice can involve catching and releasing both fresh and saltwater fish.

There are several reasons why this practice is beneficial.

The first is that killing fish will remove food resources from the area, disrupting the food chain and leading to disease in other species.

The second reason is that humans could eat it if the fish is kept.

Catch and release fishing can also help the environment. Many fish species live in freshwater streams and rivers, and their survival depends on their ability to reproduce and feed. If the fish is released back into the environment, they can continue contributing to the ecosystem. 

History of practice

The history of the catch and release fishing practice is a long one, dating back to ancient times. Even the name itself comes from a specific fish species, the yellowtail kingfish. However, catch and release are far more complicated than their name suggests and have grown in popularity over time.

One of the most common explanations for the catch and release practice is the belief that if you kill the fish, it has a chance to escape if released alive.

Another theory suggests that since the fish is alive, it has the potential to reproduce, thus creating a second-generation population. This theory is disputed by many because it contradicts the notion that the fish’s mortality rate would be high enough to make such a second generation.

When fish are caught, their blood pressure drops, which causes stress that can lead to organ damage or even death. It’s a similar situation to that of a physically restrained human.

The American Humane Association found that “a fish, while not as big as a human, is actually larger than a chicken, and therefore, not significantly less capable of suffering.”

Regardless of the reasoning, the practice is still used today and is now legal in some states, depending on the caught fish type.

The fish itself is the one determining the fate of the fish.

Over the past century, the United Kingdom has been performing catch and release for years by its fishers to prevent target species from becoming extinct in heavily fished waters.

When they first were introduced in the United States around 1952, catch and release was used as a management tool to reduce the cost of stocking hatchery-raised trout.

Some pioneers practiced catch and release fishing in the 1960s in Australia, but it wasn’t until the 1970s and 1980s that it took off.

“Catch and release” has been used by fish managers in Ireland as a conservation tool for the Atlantic salmon and sea trout fisheries since 2003. Many fisheries now have mandatory catch and release regulations.

In Switzerland and Germany, it’s illegal to catch and kill fish for sport.

The idea of “catch and release” has evolved over the years. As it has, so has the fishing industry. In the beginning, people were releasing fish into the ocean for bait. Then there was the development of artificial lures that could catch fish and still do so effectively. Nowadays, anglers are catching fish, releasing them, and catching more.

There are now four primary methods used to catch and release fish today:

1. Live-bait angling – using live bait to catch live fish

2. Trap-and-release angling – using traps to capture fish and releasing them unharmed

3. Artificial lure fishing – using artificial lures to catch fish

4. Fly-fishing – using flies to catch fish

It’s important to understand these methods because they are all used to varying degrees by various anglers. There are even different types of fly-fishing, as each has its own set of rules and other practices. For example, fly-fishing for trout may have additional regulations than fly-fishing for bass.


You can help conserve the fishing resources of North America, avoiding injury to fish from netting, by using only barbless hooks and an adequately sized theme to hold the fish without injuring them since suspending fish from their jaws or gills is very important for preventing damage to jaw ligaments and vertebrae.

Keep a tight line while fighting fish, and use lures without split rings to get the best hookups. Equip your lures with Triple Grip hooks to achieve high catch rates.

There is no evidence that bait fishing with any method is significantly more dangerous than a sport fishing trip without bait.

The effects of catch and release vary from species to species. A study on the impact of angling in North Carolina, the home of catch and release, showed that catch and release of largemouth bass (Micropterus salmoides) did not affect adult survival of the species. However, in this case, juvenile survival increased.

Catch and release have been shown to have the following effects on largemouth bass (Micropterus salmoides):

  • Juvenile fish released earlier in the season had higher survival and growth rates, but survival and growth decreased over time.
  • Young fish released later in the season had lower survival and growth rates than those caught and released earlier.
  • There was no difference in the number of fish caught and released compared to those captured and held. 

The Debate over pain in released fish

Fish caught and held before being released have experienced “pain.” This may mean that the fish are suffering and are dying in the wild because the fish have not had the opportunity to feed yet.

When fish are not fed, they lose weight and become stressed. This stress often leads to increased mortality (the rate at which the fish die).

In commercial fishing, though, fish can be handled multiple times in a short period. These fish are not usually fed but are held in pens for weeks or months.

During this time, fish are exposed to cold, hot, and wet conditions. Often, they are treated with medications to prevent disease, but these drugs can cause harm.

In these circumstances, fish experience “catch and release” stress.

Fish in catch and release practices are typically released alive, so the pain is acceptable.

Injury and mortality in released fish

Over 500 million fish are caught and released annually in the US alone, mainly in the spring and summer months. The National Fisheries Institute reports that between 1994 and 2004, recreational anglers accounted for about 15% of the total freshwater and saltwater fish mortality.

Most of this mortality occurs due to being hooked in the mouth or gills and is known as “catch and release” fishing. In the case of “catch and release” fishing, anglers can choose which parts of the fish to remove and either keep as a trophy or release. This practice is often viewed as a less efficient method of fishing, especially for fish that are young or smaller in size.

However, many released fish end up back in the water, possibly to be caught again by another angler. In the US, this can be particularly concerning with the rising number of recreational anglers and the increase in the popularity of freshwater fishing. As of 2016, an estimated 2.4 million anglers were registered with the US Fish and Wildlife Service.

The issue isn’t just limited to the US. In Canada, for example, recreational anglers account for 16% of the total catch and release mortality. However, there are no regulations governing catch and release. A lack of clear guidelines on what constitutes a legal catch makes it difficult for anglers to determine if they are releasing fish or keeping them.

Catch and release fishing laws

Some anglers may release some fish they catch back into the water to avoid harming the environment. Others may release all fish caught.

However, there are a few rules that anglers should follow to make sure they are releasing safe and legal fish. Here are the catch and release fishing laws for Minnesota:

1. Anglers must use a live baitfish such as a minnow, crayfish, or mosquito larva.

2. Fish must be released within 30 minutes of capture.

3. Fish must be immediately returned to the water, not taken to the shoreline or shoreside pier.

4. Fish must be released at least five feet from the shoreline.

5. Anglers may keep only two fish per day, of which only one may be held in possession.

6. No angler may keep more than one fish per day.

7. Minnows must be kept in a container of clean freshwater.

8. Freshwater fish are considered a nuisance and may be killed by any means other than an anesthetic.

9. Anesthetizing fish is against the law.

10. Minnows, crayfish, and mosquito larvae are not considered baitfish.

How to properly release a fish?

To properly release the fish, you need to know how to remove the hook from the fish. If the hook is still embedded in the fish’s mouth, you can yank the hook from the fish’s mouth.

However, the easiest and most recommended method is cutting the line and pulling the fish back into the water. This is because cutting the line immediately after capture allows the fish to swim away naturally, which keeps it from being harmed or entangled in other objects.

Of course, many of you are familiar with the phrase “don’t throw your baby out with the bathwater,” so let’s talk about what happens when you don’t follow that advice.

When we don’t properly handle a fish, the chances are good that the fish’s mouth and jaw may be damaged or broken. In extreme cases, if a fish is damaged, we may not be able to release it at all.

If you’re on the bank of a lake or stream, you’ll want a long net to cover both your angler and the fishing spot.

Use a pair of scissors to cut the line around the mouth of the net. This is usually where the leader ends.

Then, flip the net over.

Now, you’re ready to take out your catch.

Do fish survive catch and release? (What percent of catch and release fish die?)

Yes, fish survive catch and release. Between 84 – 98% of anglers who use this method of fishing are successful in catching and releasing.

When fishing for trout and other freshwater species, they can only be caught during specific times. For instance, salmon are only caught during spring and only in certain areas. So if you catch them, they won’t die. However, you should only be able to catch them once every two weeks or so.

On the other hand, the catch and release process isn’t essential for saltwater fish like tuna. Tuna can easily sustain itself by eating various plankton and smaller fish and can even eat themselves if left to starve. But if you catch them, you should kill them immediately.

Is catch and release ethical?

Catch and release is the practice of catching fish and releasing them back into the water to keep their population healthy. It’s completely ethical as long as you follow the laws and regulations of the region you are fishing in.

Catch and release Summary

The good news is that it is straightforward to catch and release fish.

The bad news is that there is a chance that you will catch something else.

That’s why you need to practice learning how to identify what kind of fish you are catching and how to let them go.
