Brown trout on the Kola Peninsula are special. It’s hard to even remember how many times I had to watch a look full of hope and excitement - the expression on the fisherman’s face, from which, without any words, you could read everything that it expresses. Hunting for big fish here for a short time turns into the meaning of life. Try to answer the question - where, when, with what fly, in what weather, and at what time of day is there the greatest chance of catching a real trophy. Over many years of guiding the brown trout program, I have learned to answer these questions and give practical recommendations that work.
There can be no trifles here
To begin with, it’s worth understanding one thing that can be called key – there are and cannot be trifles in trout fishing. Once you decide that “this will do” because there is no other rod, line or, for example, leader material, you are on the road to failure. The same thing happens to those who believe that they already know everything and the only task is to get to a fresh place where no one has been for a long time. The most interesting thing is when someone who is not in a very good mood perceives all your advice and recommendations as a distraction and an excuse for the lack of the proper amount of fish in the river.
One of the conditions for catching trout is compactness.
So, first things first, let's start with the right equipment. Trout fishing is always a popular fishing activity. Therefore, the compactness and practicality of all components of your uniform is one of the necessary conditions. A small, compact waterproof backpack should be one that you don't feel on your shoulders, and that you can comfortably fish in without removing it from your shoulders. The need to leave your backpack on the shore and return for it creates a nuisance and interferes with the correct fishing process. You should not take heavy and bulky cameras, a large number of flyboxes, food and additional clothing. The optimal number of boxes with flies is 2 or 3.
Spikes - pros and cons when fishing for brown trout
It’s hard to imagine more comfortable and convenient waders for such fishing than the SIMMS G3 Stockingfoot. A good compact folding staff, SIMMS Wading Staff, will also be an indispensable assistant for you when moving and wading fishing. You should choose lightweight wader boots, and in most cases the sole on them is made of felt without spikes. However, if the water is “blooming” and there is a lot of algae on the underwater rocks, then you cannot do without thorns. It should be remembered that at low water levels when wading fishing, the spikes create additional noise, which scares away cautious fish.
Don't be tempted!
The chances of catching large trout increase when using delicate gear. Class 4-5 rods with a classic length of 9 feet (2.7 m) are what you need. Do not use rods of higher classes, do not fall into the temptation of having a rod with a margin of strength and power. Without proper technique, this will not help you make longer casts or help you deal with larger fish. But splashing a larger cord through the water will help scare it away. Coarser shock absorption will not allow the use of thin leashes and the pleasure of landing large fish will sharply decrease. For me personally, the ideal rod for this type of fishing is the Redington Crux 590-4 single-handed rod. Digressing somewhat from the topic, I want to say that fly fishing equipment is something that must always be selected very precisely. Therefore, if you don’t have what you really need, then don’t buy anything. Just keep looking for what you need.
Fishing for brown trout using a spinning rod
Spinning trout fishing has a very dynamic and uneven retrieve as its main feature. Brown trout are particularly nimble and agile, as well as “love” for sharp and strong jerks.
In this regard, during the retrieving process, you should make sharp movements with the rod, while stopping the reeling of the fishing line. Although brown trout is a very shy fish, bites are often observed close to the shore, which is why it is advisable to closely monitor the bait until the very end.
Tackle for catching brown trout
The tackle must satisfy two main conditions: to be balanced, and also to provide the fisherman with the ability to cast long distances. Other characteristics are less important and therefore are selected individually. Most often, a medium action rod and a spinning reel are used. The length of the rod should be quite large, around 2.7-3 m. Both monofilament and braid are used.
Don't get carried away with tapered leaders!
The main qualities of a fly line are its ability to break through the wind, make long casts and work with large streamers. It is difficult to find a cord that would satisfy all these qualities. The most suitable one can be considered RIO OutBond Streamer WF5F. Sinking leaders are used extremely rarely, so you don’t have to have them in your arsenal at all. Conical leaders and nylon leader material are only needed when fishing with dry flies using the dead swim method. In all other cases, it is better to use a fluorocarbon tippet in the size of 0.2–0.25 mm.
Float rod
For those who like to “sit with a fishing rod,” we advise you to take the telescopic version, which has good sensitivity.
The unbridled nature of brown trout places certain demands on the rod:
- length not less than 5 meters;
- it is desirable that it be made of carbon fiber (even better, with the addition of composite materials, for example, boron-containing fibers). This rod is very light, has high flexibility, which allows you to make sharp casts over fairly long distances;
- varnished rather than painted (gives additional strength).
If you plan to hunt for a trophy specimen, a braid of nickel threads will not be superfluous. The cost of such fishing rods is high, but there is a little secret here: serious manufacturers, releasing the latest models to the market, reduce the price of collections from previous years.
The rod is equipped with a spinning reel, monofilament fishing line 0.2–0.3 mm, a large hook No. 6–8 and a sliding float. Suitable baits include a worm, caddis fly larvae, and live bait (it’s good if it comes from the same body of water).
Best synthetic baits: nymphs, wet flies or fancy flies. They are also used when fly fishing for brown trout and trout. With this method, the easiest way is to let the artificial bait go with the flow (“drift” wiring). Additional movement is given to the fly by twitching the rod tip.
The bite of brown trout is very sharp. The float instantly goes to the side or under the water. It is important to make the cut quickly. Otherwise, the brown trout will spit out the hook.
About the radius of invisibility of the line when fishing for brown trout
In some cases, in sunny weather and low water levels, you can use a 0.18 mm leash, but this immediately sharply increases the risk of breakage when fishing for a trophy. The length of the leash when fishing with streamers, skaters, “Chernobyl ants” and any dry flies drawing on the surface is 2.5-3 meters. This leader simply attaches to the loop on the tip of your fly line! And nothing more - everything ingenious is simple! Of course, you won't always have the perfect fly presentation as you would with a tapered leader. Sometimes a “wind-knot” will form. But the radius of the “invisibility of the cord” and the conical leash (which is visible to the fish in the same way as a fly cord) with a long retrieve will be very large. Large fish are very careful and this factor is very important when fishing for brown trout.
Tackle
The choice of gear is always influenced by several key factors:
- expected/priority size of brown trout for fishing;
- water level and temperature;
- type of planned baits;
- size of the reservoir (river/lake).
But in any case, spinning rods will be the most powerful within the test for the baits that you plan to use for catching brown trout. For example, if your bait is in the weight range of 3 - 15 g, then it is better to focus on spinning rods with a test weight of 8 - 15 g. After all, you will have to look for fish throughout the entire thickness of the water, both in the lake and in the river. And more often, heavier baits will be appropriate for this than during the rest of the spinning season.
In recent years, I’ve been taking two sets of gear with me when fishing – river and lake. The difference between them is not only the length/test combination. The lake version is a rather long classic “salmon fish” with a medium-fast action, equipped with a reel with a gear ratio of 4.8:1 – 5.2:1.
When fishing on a lake, you need to cast the bait as far as possible and keep the blank working throughout the entire fishing. It is logical that the river set is shorter, while the spinning rod will be faster in action, and the reel will have a higher gear ratio. If for some reason I have to choose between these two sets in favor of only one, then I will almost always choose the lake one - the power reserve and better control over the fish when playing will, with a high degree of probability, decide in my favor the fight with a large specimen.
The casting distance on lakes, which I wrote about above, is achieved through the use of braided fishing line. I prefer 8-strand “braids” in the diameter range ##0.6 – 1.0 (according to the Japanese classification). The specific diameter from this range depends on the weight of the baits used.
Size #0.8 can be considered the “golden mean” - the strength of the cord is enough to cope with calm water and large specimens, and the reach of lures weighing over five grams can be called excellent. I consider it mandatory to have a leash made of fluorocarbon (or, in extreme cases, regular thick fishing line) with a length of a meter or more - to prevent the cord from being cut on the sharp edges of stones when retrieving and playing.
For fishing on rivers and streams, I reel in a classic fishing line. Its abrasive resistance and ability to stretch, helping to absorb the short jerks of the fish, are key points when choosing. For visual control of the bait and fish at the time of fishing, brightly colored fishing lines are simply ideal, while they remain practically invisible to the fish.
The history of extreme trout fishing
In addition, it is worth talking separately about fishing techniques and tactics, the use of flies, the rules for tying them and the correct landing of spotted monsters. But I will talk about this in the next article. And now I want to talk about one extreme fishing for a very large brown trout on the Kola.
It was the month of August and a very dry summer, low water levels and a half-dried riverbed in the upper reaches of the Vostochnaya Litsa River. It would seem that large fish should go into the lakes, into deeper and more familiar places. There was only half an hour left before the end of fishing and boarding the helicopter to fly to the camp. The water level is so low that the river flows as if between stones.
And now, there is a small hole on our way. The second cast is on a fly called “Kola Killer” and the surface of the water boils after hooking. One, second, third candle of unrealistically large fish for such a place. The splashes from the fish falling into the water after jumping fly to the shore and make the coastal stones wet. And then the fish rushes upstream, swims between several huge stones and entangles the cord between them. In this case, a cliff is inevitable, but it was at this moment that the monster got tired and stopped for a short break. These seconds were enough for the guide to rush into the water and free the caught cord.
Next, the fisherman jumped over the stones like a real acrobat, trying to be at a minimum distance from the fish. When the fish was almost tired and was close to the landing net, it still had enough strength to rush into the underwater grotto between the stones adjacent to each other. And at this moment, logically, there should also be a break, but the resourceful fisherman, who had all this happening right under his feet, grabbed the end of the cord with his hand. Fortunately, the brown trout was very tired, and he managed to pull it out of this ill-fated grotto by hand by the cord. When the fish was in the guide’s landing net, the cry of joy was heard by all the deer within a radius of a couple of kilometers. This is what it is like, extreme fishing and true fishing happiness. By the way, this brown trout turned out to weigh 5.5 kg and was caught with a 0.24 mm leader.
Brown trout
Brown trout - Salmo trutta
Salmon family - Salmonidae An anadromous and freshwater species of the northern Atlantic Ocean. The marine life period lasts up to seven years. Trout that linger in lakes and streams turns into lake or brook trout, and vice versa, trout that go out to sea turns into migratory brown trout. There are “spring” and “winter” forms.
In Russia, it lives in the basins of the Barents, White, Baltic, Black and Caspian seas. Forms several subspecies, of which four are found in Russia: Salmo trutta trutta
– common brown trout (anadromous) and trout (freshwater), in the basins of the Baltic, White and Barents seas east to Pechora;
Salmo trutta labrax
- Black Sea trout, in the basins of the Black and Azov Seas, forms freshwater forms of trout;
Salmo trutta ciscaucasicus
- Cis-Caucasian trout, in the Caspian Sea basin, goes to spawn in the rivers of the western coast (except for the Kura), forms freshwater forms of trout everywhere;
Salmo trutta ezenami
- Eizenam trout, lives only in Lake Kezenoyam (on the border of Chechnya and Dagestan).
The length of the head is no more than a quarter of the length of the body, the mouth is large, the upper jaw extends noticeably beyond the posterior edge of the eye. The caudal peduncle is higher and the caudal fin has a smaller notch than that of salmon. There are numerous black spots above and below the lateral line. There are red spots on the sides of the body. In rivers, the color is brownish on the back with a silvery tint on the sides. The size of fish varies depending on habitat conditions. In small rivers, residential brown trout can be no more than 25 cm, in large lakes - up to 1 m, weighing up to 8–13 kg. Migratory brown trout are larger – up to 1.4 m and weighing several tens of kilograms.
The juveniles feed in the river on small crustaceans and insect larvae, and partly on small fish. Adult fish are predators. Unlike salmon, trout going to spawn also feed in the river, but when entering fresh water the feeding intensity decreases, increasing again after spawning.
Like salmon, it comes to spawn with a different state of reproductive products; depending on this, it spawns either in the year of entry or a year later.
Spawning usually occurs in September - November in the upper reaches of rivers on sandy and pebbly soils. Spawned individuals partly immediately migrate to the sea in the same autumn, partly overwinter in fresh water and migrate the following spring. The fry go through the parr stage (spotted coloration). Before sloping into the sea, the color changes. Migration occurs at different ages depending on feeding conditions. Typically, juveniles spend in the river from one to six (and even seven) years. Some males participate in breeding for the first time before going to sea. Literature
