The highest temperature is 23 degrees Celsius, the lowest temperature is 8 degrees, is it better to

The choice of water depth is very important for fishing, and I have always believed that the first factor to consider when choosing a fishing position is the depth of the water. The main factors affected by water depth are: pressure, oxygen content, and water temperature.

In addition, for fish, shallow water has high oxygen content, a large number of microorganisms, and abundant food, while deep water areas are relatively safer and conducive to fish hiding although they have low oxygen content and strong pressure. Regardless of safety and water temperature, fish will prefer to move in shallow waters, as oxygen content and food are always necessary for fish to survive.

However, affected by the change of water temperature, the depth area of fish activity will continue to change, and the influence of water temperature on the law of fish activity is very obvious, different water depths will produce different water temperatures, and water temperature is affected by air temperature, so today we will take a look at the correlation and law between the three factors of air temperature, water temperature and water depth.

For most of the freshwater fish in our country.

Species, when the water temperature reaches 25 -28, the fish are most active and have the most appetite, so the fish will try to choose the best water temperature area to move and feed. For anglers, only by choosing the right water depth can you ensure that you can catch more fish. How do you find the right water depth?

For the sake of demonstration, we will roughly divide it into shallow water, middle water, and deep water.

Regularity: Shallow water areas heat up quickly and cool down quickly; Deep water heats up slowly and cools down slowly.

The shallow water area is in direct contact with the air temperature layer, so the influence of air temperature is also the most obvious, that is to say, the reason why the water temperature changes is because the temperature change first affects the shallow water area, and then passes from the shallow water area to the middle area, and finally affects the deep water area. Deep water is the most insulated, because it is not directly affected by air temperature, so it heats up slowly and cools down slowly.

In other words, when the air temperature is higher than the water temperature in the shallow water, the water temperature in the shallow water will first increase with the air temperature, and then the heat will be transferred to the middle zone, and finally the heat will be transferred from the middle zone to the deep water zone. The heat will gradually decay in the process of transfer, so the water temperature in the shallow water area will be the highest, and the water temperature in the deep water area will be the lowest.

On the contrary, when the air temperature is lower than the water temperature in the shallow water area, the water temperature in the shallow water area will first decrease with the air temperature, and then gradually absorb the heat in the middle and deep water areas, resulting in the water temperature in the middle and deep water areas decreasing, and finally the water temperature in the shallow water area will be the lowest and the water temperature in the deep water area will be the highest.

Now that we understand the relationship between temperature, water temperature, and water depth, let's take a closer look at some common climate changes to learn more about how to choose the right water depth for fishing.

Practical skills 1: the selection and change of water depth for summer fishing.

The most striking feature of summer is the heat and high temperature, under the influence of strong sunlight, the water temperature in the shallow water will quickly rise to more than 28, due to the high water temperature in the shallow water, the fish will be more concentrated in the middle or deep water. So, fishing in the summer when the sun is strong, you can choose it in the morning.

Deep water fishing is recommended. In fact, fishing is not only based on the temperature, but also on your own equipment, fishing methods, and of course, when the water temperature is high, you can fish in deep water.

Fishing is possible when the maximum temperature reaches 33°C. The high temperature is suitable for bighead carp, tilapia and dace fishing. Precautions for fishing for fish species (crucian carp, carp, etc.) at room temperature when the maximum temperature reaches 33°C:

1. Choose deep water as the fishing spot, there will be a temperature difference of more than 7 ° between the deep water and the air temperature, which is suitable for fishing crucian carp, carp and other normal temperature fish at high temperatures.

2. Choose shaded waters such as tree shade or the back of buildings as fishing spots, suitable for fishing crucian carp, carp and other fish at room temperature at high temperatures.

3. Choose the water area with new water inflow as the fishing spot, which is suitable for fishing crucian carp, carp and other fish at room temperature at high temperatures.

Yes. Fish for deep water. So, in the summer fishing pool, you have to find a place to fish in deep water.

Fishing at 16 degrees Celsius is shallow, but if the temperature is unstable at this time, you need to fish deep. When the temperature is around 16, many fish are already in good shape. At this time, when the shallow water temperature rises under the light, you can fish in the shallow water, which can be selected as a shallow water with more oxygen and food.

However, sometimes the temperature has just risen and is not stable, and the fish are generally still active at a deep level, so you can try to fish deeper.

Fishing needs to be decided whether to fish deep or shallow depending on the specific situation of the fishing, that is, whether to fish in deep water or shallow water. Temperature is a factor that has an important impact on the depth of fishing, and it is necessary to take into account the specific temperature conditions at the time. When the temperature is 16, the temperature is neither high nor low.

In this case, most of the fish have already spoken. Moreover, when the light comes out, the shallow water temperature rises faster, and the fish will move to a shallower place, so the number of fish distributed in the shallow layer at this time is relatively large, so you can consider fishing shallow.

In general, it is possible to fish in shallow waters, but when choosing a specific location, in addition to the depth, you also have to consider the amount of oxygen and the amount of food.

Fishing in waters with more food and more oxygen. However, shallow fishing is not an absolute option, and sometimes you have to fish deep. Because it's 16, it's not a particularly hot time.

If the temperature is not stable at this time, or it has just risen to about 16, then many fish are still living in a deeper position, and the fishing depth is relatively more suitable at this time.

As mentioned above, when the temperature is around 16, you can try to fish shallow, but if the temperature is not stable, you need to fish deep. Whether fishing near or far is similar to fishing deep and shallow. Generally speaking, if the temperature can be stable at about 16, you can fish closely, that is, in the shallow position close to the shore.

However, sometimes the temperature is unstable and just rises to around 16, so you need to fish a little farther away. At this time, many fish like to live in the middle of the water, and it is relatively more suitable to fish far away.

When the temperature is 14 degrees Celsius, it is better to fish in deep or shallow water.

14-degree fishing generally involves deep water, but sometimes shallow water is also required. The temperature will affect the distribution of the fish, and when the temperature is in this condition, it is generally not particularly suitable, and the fish are still in relatively deep water, so it is generally fishing in deep water at this time. However, sometimes the air pressure is low and the fish will float, so it is better to fish in shallow waters.

In addition, some fish are pelagic and pelagic and need to be fished in shallow water when fishing for them.

Large temperature difference between day and night: If the temperature difference is relatively large, you should choose whether to fish deep or shallow water according to the temperature at that time. If the temperature is high, the fish like to move close to the surface, so fish shallow, and if the temperature is low, fish a little deeper.

1. Fishing skills in shallow water.

When the temperature is too high, it is necessary to judge the situation to find a suitable fishing spot, but generally speaking, we can choose to fish on the surface of the water with aquatic plants on the bottom and a relatively flat bottom. Waters that are too clear or muddy are not suitable for fishing.

When fishing in shallow water, you can use the Xinyu method of forced fishing, that is, after the bait enters the water for a period of time, if there is no fish to eat the bait, you can gently lift the rod to attract the attention of the fish. We can nest near the fishing spot of our choice to gather the fish together and increase the likelihood of catching fish.

2. Techniques for fishing deep water.

When the temperature is too low, the temperature in the shallow water near the shore is no longer suitable for the fish, and it begins to gradually move to the deep water area, and the fish mouth weakens. For deep-water fishing, and tandou should be fished in the morning or evening in spring and autumn, because the sun is weak at this time, and the temperature in the deep-water area is more suitable.

Choose a long, stiff rod. Deep-water fishing is generally more than 2 meters deep, so it will be very powerful when fishing for deep-water fish with a long rod and a hard rod. Also choose a float with a heavy lead content, so that the float can bear a wide range of weights and the hook will quickly reach the deep water.

In temperatures between 23 and 8 degrees, it is generally possible to achieve good results in both shallow and deep waters, depending on the target species and the environment in which the water area is served. Here are some common suggestions:

Target species: If your target species is fish that prefer to move in deep water, such as demersal fish or large fish, it may be more advantageous to fish in deep water. If your target species is fish that prefer to move in shallow water, such as grass carp, crucian carp, herring, etc., then it is more advantageous to choose to fish in shallow water.

Water environment: If you are in a relatively flat water with relatively shallow depths, it may be easier to find and catch fish in shallow water. If the topography of the water is complex and the water depth is relatively deep, it may be easier to find and catch fish by fishing in deep water.

Weather conditions: When the temperature is high, fish generally prefer to be active near the bottom or in deep water, and it may be more advantageous to fish in deep water at this time. When the temperature is cold, fish tend to congregate in shallow waters, and it may be more advantageous to fish in shallow water.

In general, with temperatures between 23 and 8 degrees Celsius, it is possible to achieve good results in shallow or deep hidden water, depending on factors such as the target species, the water environment and the weather conditions.

The temperature is low, and the fishing is generally deep.

The temperature is low, and the fishing is generally deep. Fish in the water will live in different water layers depending on the temperature, so the depth of fishing will be different depending on the temperature or situation.

When the temperature is relatively low, the temperature in the shallow layer is too low, which is not suitable for fish to survive, while the deep layer of Wanxingzui is more suitable for activities, and the fish are basically concentrated in the deep layer, and the fishing depth is more suitable. However, it is also necessary to take into account the air pressure, if the air pressure is low at this time, the fish may float up to breathe, and you can consider fishing shallow. In fact, you can also look at the mouth of the fish, as long as you can catch the fish.

When it comes to fishing, anglers will encounter different specific situations. For example, from the perspective of fishing depth, if fishing is carried out under different temperature conditions, the fishing depth will be different.

Sometimes, the temperature is not particularly suitable, but a little lower, and if this is the case, the depth of the fishing is generally chosen because of the habits of the fish.

When the temperature is suitable, fish are more willing to move in shallow waters, but as the temperature decreases, the temperature in shallow waters is relatively unsuitable, but the temperature in deep waters is higher, which is relatively more suitable for most fish species. With this in mind, it is appropriate to fish deep at a deep level.

Of course, when fishing, other conditions may be different, such as air pressure. In such an environment, the depth of choice can also be different. For example, when the air pressure is very low, the fish may also move shallow due to the air permeability, so you can consider fishing shallow.
