In spring, fish recover from a winter dormancy, spend cold and hunger, and need to replenish their physical strength urgently. Salt will be of great use at this time. What is the specific function of salt in fishing? I wonder how much do you know about this? The following is an introduction to the role of salt in fishing, I hope it will help you.

The role of salt in fishing

Fish need bait with high protein content, and protein contains a large number of polar molecules, which can easily combine with water to form hydrogen bonds, so that water molecules can be firmly adsorbed on the surfaces of these polymer chains and form water films. In order to make protein dissolve more, salt should be properly added to the bait containing protein to combine the anion of salt with the cation of protein, so that the solubility of protein will increase, which is more conducive to the absorption of fish and can increase the energy provided by the bait itself for fish. Although we can't see much change, the fish in the water will react greatly to small changes. They eat the bait on the principle that the fittest comes first. Of course, they eat bait that is easy to absorb and digest first. But we must pay attention to the new amount, which is about 0.5% of the feed ratio. Once too much salt is put into the water, the salt will dissolve and the electrolyte concentration will be too high. At this time, high-intensity ions will squeeze protein with a certain pressure, which will make the protein chain taut and affect the solubility. And it's too salty, and freshwater fish won't like it too much.

In summer and autumn, it is the time when fish need the most salt. First of all, the water temperature is very high in summer, and fish need to consume a lot of physical energy when they are active, so the oxygen capacity in the water is low. Fish are in a negative oxygen state most of the time, so it is urgent to supplement a certain amount of salt. In fact, we humans are also like this. Drinking normal saline in summer will greatly relieve the fatigue of the body. So is the fish. Their own foraging activities will consume a lot of physical strength, plus the huge physical strength consumed by chasing courtship and spawning in summer and autumn, which will make them feel exhausted. Salt can promote them to absorb nutrients from foods with low physical strength, enhance their ability to carry and transport oxygen in their blood, and also have a good disinfection effect on the bodies of fish after spawning. At this time, put the salty bait into the water, and the fish will bite wildly. Secondly, summer and autumn are also frequent seasons for parasites and germs. Salt can clean fish gills and inhibit the growth of bacteria, which has a good preventive and therapeutic effect on fish congestion, poisoning and enteritis in summer. Generally, the increase this season can be around 1%.

The reason why salt is added to the bait for fishing in winter is because fish are not very active in winter and their metabolism slows down; The low temperature of the external environment or the freezing of the water surface make the exchange of organic substances between the water and the outside world scarce, so that harmful bacteria in the water can not be decomposed and eliminated in time. Therefore, most fish are infected with many germs in spring, and some are visible to the naked eye, such as white defects and panel ulceration. Some of them are invisible to us. At this time, the water is short of food, so it is difficult for fish to find food to improve their immunity. Because there are no doctors in the fish world, they all eat food and get corresponding ingredients from it to prevent diseases or destroy infected bacteria in advance. At this time, we add a certain amount of salt to the bait, throw the rod for a period of time to make a nest when fishing, and the bait is constantly sprinkled into the water. The salt in the bait is easily soluble in water, and it has a strong osmotic effect in water, which can change the osmotic pressure of pathogenic microorganisms in water, inhibit the growth of pathogenic microorganisms or directly kill pathogenic microorganisms. The water near the Bird's Nest is relatively "clean", so there will be relatively few bacteria near the Bird's Nest. When fish feel this, they will gather here quickly, and even if the bait selection is incorrect, they will have better harvest.

Fishing skills of crucian carp

1. Pay attention to making a nest. According to the different time, terrain and waters, measures should be taken to make nests or feed them. For example, the bait nest of "spring fishing shoal" mentioned above is better than nesting on the spot. If a pond is overgrown with weeds and it is difficult to get out, but there are many crucian carp there, not far from home, or convenient transportation, don't let go. After choosing the fishing position, open a "hole" of about 1 square meter to completely remove weeds or other obstacles. Feeding the bait on the first day and fishing the next day is far better than the new "hole". If we can find the rotting corpses of small animals such as dead cats and rotten dogs, and tie up 1 stone and sink into the nest, we can get a bumper harvest for 4-5 days. If you are close to home, you can pour leftovers and cow dung into the nest, and the effect is good.

Make a three-dimensional nest. Suitable for deep water under steep slopes or levees. Bait preparation: stir-fry the crushed bean cake residue, add 1/5 sheep bone powder, and bag for later use. After reaching the fishing position, add 60% wet soil to the shore, mix well and rub it fine, and sprinkle it into the fishing area to form a three-dimensional nest. Tie three hooks with a hand lever flush with the pole line, and cooperate with the float to make the lower hook just sink to the bottom, with the upper hook hanging about 8 cm from the bottom and the other hook hanging between the upper hook and the lower hook. As the bait is continuously put into the fishing area, more and more people will catch fish. In the first half hour, there may be few fish, and later, there may be more fish. Even before the hook landed, it was caught by the fish halfway. It is common to catch two fish in one pole, and occasionally catch three fish in one pole. In order to save bait loading time, red earthworm can catch 3 ~ 5 fish at a time without changing bait by dipping in essence. Bait mixed with sediment will inevitably "brush" like rain when thrown into the fishing area, but as long as it is sprinkled for a few times, the fish will not be afraid. Not only crucian carp love to bite hooks, but carp also love to bite hooks.

When fish compete for food on the surface of the water, it shows that the bait throwing rate decreases because of too frequent and too many baits. It is necessary not only to stop feeding, but also to lift the bottom hook to make it close to the water surface and pull it into the fish, which will lead to horizontal drift. Use the method of throwing the rod or lifting it up and down to lure the fish into the bait. After the bait is suspended, the fish will sink to the bottom again for food.

2. Master the characteristics of big crucian carp. In the backwater vortex of the river in rainy season, near the sluice of the reservoir and at the backwater inlet of the pier, it is often the gathering place of the big crucian carp. In the pond densely covered with duckweed, there is a "snap" sound, or duckweed arches, or the head is exposed to oxygen, mostly the whereabouts of big crucian carp. If the bait hook hasn't sunk to the bottom, it stops halfway and is swallowed by the fish, and the fish slowly floats up or lies still, mostly because of the big crucian carp. The smaller the drift, or the slower the drift speed, the larger the individual of crucian carp. When observing the small bubbles of the fish star after making a nest, we can see that there are larger bubbles in the dense bubbles, which is the signal that the big crucian carp enters the nest.

The benefits of fishing for the elderly

1, the fishing environment is conducive to health care.

Fishing in rivers, lakes and seas is a good environment for health care with fresh air, abundant sunshine and low noise. There is plenty of oxygen in the seaside air of rivers and lakes, and breathing fresh air often can cause various corresponding good physiological reactions of human body; Sunlight can make people get a strong and handsome panel and a ruddy and healthy face. After the human body is irradiated by ultraviolet rays from the sun, it can enhance the blood circulation of the panel and viscera and promote metabolism in the body; Urban noise has seriously polluted the environment, and people often go fishing in open and quiet waters. Quiet environment can eliminate the fatigue of both ears and help to maintain good hearing function.

2. Regulate emotions and maintain mental health.

Fishing can control and eliminate all kinds of negative emotions. Taking part in fishing activities is helpful to improve the interest of life and activate various physiological functions. It is a good way to maintain mental health and prevent depression, mental depression, anxiety and irritability. Fishing makes people feel comfortable, emotionally stable and energetic.

3. It is beneficial to exercise the mind and improve memory.

Fishing is also composed of brain, hands and eyes, as well as static, intentional and dynamic AIDS. When fishing, the eyes, brain and mind focus on the movement of the buoy, quietly, with the intention of showing the sky and moving in silence, which has played a positive role in improving people's vision and sensitive response function.

Frequent fishing is also good for enhancing people's memory. Fishing needs to constantly sum up experience, such as under what circumstances, what pond mouth, what season, how many rice nests to play, what fishing skills to use, what fish to catch and so on. It is also a good exercise for a person's memory to record it after summing up or put it in his mind.

It is understood that fishing can also play a good therapeutic role in hypertension and neurasthenia of middle-aged and elderly people. Especially for patients with hypertension, they often can't do strenuous exercise, are afraid of falling, and are prone to impatience. When they are impatient, their heart beats faster and their blood pressure suddenly rises. Through fishing, many people feel good about themselves and their blood pressure gradually becomes normal.
