Fishing structure

Fishing structures

Drag the window from left to right to see both types of fishing structures.

Structure 1 and Structure 2

 

 

 

 

 

 

 

 

 

There are many structures at different places on this model map, and fishing will be done in a stationary boat or in boat in motion.

The example below shows structures for fishing on a stationnary boat. Starting from the top, you have the following fishing spots:

 

1. At a river exit

2. On the tip of a gravely point

3. In front af lake grass

4. At a rocky river exit

5. On both sides of a narrow passage

6. And again at a small river exit

 

 

On the second map, there is only one fishing structure and the boat is in motion. Around and close to this fishing structure, starting from the top, you will see a gravelly point, a river, a gravelly shore, another river and a bit further, lake grass and an island of which half the shore is gravelly. Overall, this site represents a habitat that is likely to contain several small populations of brook trout. During the hot water season, they may live in the deeper zone of the body of water, but they are always as close as possible to the structures near the shore. They will have access to colder water and to food at all levels of the water column.

 What is a fishing structure?

Any site that is likely to promote the grouping of a species of fish at any given time during the fishing season can be considered a fishing structure.

A lake is not a fishing structure, neither is a river. A structure is formed by the presence of various natural elements that offer some benefits to a fish species. This species will be protected from predators and will easily find food in abundance, the water temperature will be adequate and the amount of oxygen dissolved in water will be sufficient.

The natural elements necessary for a structure to attract fish are:

  • River mouths
  • Bays
  • Lake grass
  • Rocky islets
  • Islands and groups of islands
  • Gravelly points
  • Escarpments
  • Narrow passages
  • Underwater talus
  • Underwater islands
  • Submerged rocks
  • Thermocline
  • Various strata of the water column

Therefore, a structure is a specific site on a lake or river. Some fishing structures are only about twenty feet in diameter, while others can extend over a mile. Several structures can be found on the same body of water, from a few to several tens. In some cases, the fisherman will prospect only a small, well-defined fishing structure such as a river mouth, where a large quantity of fish can be found. The craft will then be anchored and the fisherman will use fishing techniques and lures adapted to the structure in order to prospect it effectively. In other situations, fishing will be done slowly over long distances along the shore in search of small groups of fish. In that case, the fishing structure will actually consist of several small sites following one another along the shore. There may be a first small structure shaped by a beaver hut, a little farther down it’s a small stream that would form the structure and so on and so forth over more than a mile. The fisherman will use different techniques depending on what he sees while fishing along the shore.

Yield

The various fishing structures that a body of water can offer will never be productive all at the same time. Some will be productive only at the opening of the season and others, only in summer. Most of the time though, the fish will approach structures near the shore at the opening of the season and will gradually move away from it as the water warms up during the summer. The water temperature is most often the determining factor for fish to be present in the fishing sites. Other elements, such as the level of brightness, will cause the fish to move up and down in the water column over very short periods of time. This shift of the school of fish may occur several times during the same day, while a change in water temperature will cause its permanent displacement until the next season.

Fish Location

Obviously, if you wish to catch fish, you must first locate them in the body of water. The practice of fishing on a site where there are no fish is the first reason why many fishermen catch very little fish or none at all.

The application contains different model maps for a given species. Since it is impossible to reproduce all North American bodies of water in the database, the map samples contained in the application represent virtually all types of bodies of water on which you would be likely to fish. Some maps only represent part of a very large body of water, while the entire body of water can be seen on other maps. Some bodies of water are deep and others are shallow. We have made this choice to help you become familiar with the different fishing structures that can be found on any kind of body of water.

When you make a selection of the fishing conditions, you will see two maps. One of them will show the stationary fishing structures in which the boat is usually anchored, while on the other map you will find larger structures in which fishing while the boat is in motion is mainly practiced. 

Configuration

If you are familiar with a body of water on which you have already fished, you can easily identify the sites that resemble those you see in the application. Do not only consider the general configuration of a structure, but look at it in detail. Pay special attention to the following elements by looking at the water, underwater and around the site. Get used to analyzing a fishing structure in this order:

  1. The shore profile (bays, mouths, points, talus, rocky capes, narrow passages, etc.)
  2. What is the shore composition
    1. Coarse gravel
    2. Coarse rocks
    3. A mixture of gravel and rocks
    4. Fine gravel or sand
    5. The average slope of the shore                                                                        
      1. A gentle slope (2in / 12in)
      2. An average slope (4in / 12in)
      3. The bottom of the structure, where the same elements as those observed on the shore should ideally be present
      4. The presence of the following elements in front of the fishing site once the water has warmed up:
        1. A river mouth
        2. A shore with a gentle to medium slope
        3. Gravel or rocks on the shores and on the bottom
        4. Lake grass
        5. Small islands or a group of islands
        6. Birds that feed on fish (cormorant, tern, loon, mergansers, kingfisher)

Careful observation of the composition of a fishing site is the most important aspect of fishing. It’s the fish habitat and it’s unnecessary to concentrate your fishing efforts on a site in which there are no fish. When the presence of fish is difficult to determine with certainty on a fishing site, either by seeing jumps or broth on the surface or with the help of a sonar, you will have to expect having to probe several different sites for short periods of time. However, you must not rely on luck or chance to get results — it is far better to apply a systematic and thoughtful approach, especially on large body of water. Once you have spotted the fish, you will be able to stop on this structure longer.

Take time to thoroughly analyze the body of water on which you are fishing in order to discover all the structures it contains, and make a new selection of fishing conditions as soon as the weather changes. Some fishing structures are very small and are only productive for a few days during the season, sometimes for only a few hours a day. However, it’s not because there are no fish at any given time that a fishing structure has to be abandoned. Return early in the morning, when thick clouds darken the sky or when the wind comes from the south. Use the application in various fishing conditions, as each one of them can make a structure productive at one time or another during the day.

In the Fishing Structures page, a “+” sign appears on the top right-hand band where you can read various relevant information concerning the period during which you fish.
