How to observe the water situation and fish situation in the river?

Fishing Observing Water Situation and Fish Situation Fishing Observing Water Situation and Fish Situation Fishing Fishing Fish live in water, so fishing must first deal with all kinds of water bodies that protect and hide fish-ditches, rivers, reservoirs, lakes, rivers and even oceans. Whether the fish situation in a certain water area is suitable for fishing depends on the observation of the water situation in the fishing water area, so as to know whether there are fish in the water area, what fish there are and how many fish there are, so as to correctly choose the fishing water area and fishing place and determine the bait and fishing method. The water regime mainly includes the changes of water color, water movement, water smell, water temperature, water depth and its flow. The water movement is a sensitive reflection of fish's movement in water and their foraging. So according to the situation of water, we can judge the situation of fish in water by looking at the face and color. This is an important preparation before fishing, just as important as choosing favorable terrain in battle. First, observe the color of water. Water color refers to the color and turbidity of fishing waters. Water is a colorless and odorless transparent liquid. Due to the application of various feeds and fertilizers, a large number of plankton, dissolved substances and suspended solids, or the pollution of factory wastewater and domestic sewage, as well as the agitation of fish when eating, the water body presents various colors. Water color has a lot to do with fishing, an experienced fisherman. According to the color of water, we can judge the situation of fish and the type of bait, so as to choose the appropriate fishing method. The common colors of fishing water surface are: light yellow water.

Pale yellow water with transparency of 30-40cm. There are many yellow silk grass, algae-free, Chlorella and Synechococcus in the water, and the water quality is thin. Under normal circumstances, the fish in this water have a great appetite and like to eat animal bait. Yellow and green water

That is, yellow-green water, the transparency is about 20-30 cm. The water is rich in green algae, dinoflagellate, gymnosperms, brown algae and yellow algae, and the water quality is neither fat nor thin, which is suitable for fish growth. Fish and animal and plant bait in this kind of water like to eat. Dark green water

Dark green water, the transparency is about 10 cm. Green algae, Chlorella, etc. It thrives in water, with more gymnosperms and Chlorella. The water quality is rich, but there is no wind and the temperature is low. In rainy days, fish easily float their heads due to lack of oxygen, which is not suitable for fishing. For example, if the wind blows in the second or third grade, the temperature is about 20C, and the sunshine is good, the fish will have a bigger appetite, so they can fish, and the intermediate fishing or towing fishing is better. Light brown water is light brown water with a transparency of about 20 cm. There are many dinoflagellates, brown algae, green algae and some humus in the water, so the water quality is thin. Under normal circumstances, the fish in this water have a great appetite and love to eat plant bait. Dark brown water with transparency less than 10 cm. There are too many brown algae and dinoflagellate in the water, and some of them also contain too many minerals and humus, so the water quality is fat. In case of abnormal weather such as rainy and depressed weather, fish will float their heads due to lack of oxygen. When the weather is clear, fish eat more vigorously, but they eat more plant bait and don't like animal bait. Some dark brown water is caused by pollution, fish don't eat it, and some even die of poisoning. Tonglushui

In this water area, ANABAENA, Nostoc commune and other cyanobacteria multiply in large numbers, which makes the water green and turbid, especially in summer. In case of abnormal weather, algae died in large numbers. Decomposition will not only consume oxygen in water, but also produce toxic substances, which will affect the growth of fish and even kill them by poisoning. Not suitable for fishing, but the water turns slightly blue, with high transparency and active fish, indicating that there are fewer cyanobacteria in the water and oxygen is released under photosynthesis. Fish often eat very fierce, and the fishing effect is quite good. The clear water area is crystal clear, and the transparency is above 1 m. There are basically no algae, zooplankton and other organisms in this water area, and there are no or few fish, which is not suitable for fishing. So there is a proverb: "Clear water means no fish." Abundant water

This kind of water is dark green, yellow, brown or grass blue, with a transparency of 20-30 cm, rich in plankton and abundant in oxygen. The fish in this kind of water have a big appetite, grow fast and have a high rate of eating hooks. Generally, there is no such fertilizer in natural water bodies, and it is mostly obtained through fertilization and fish pond culture. However, in case of abnormal weather such as thunderstorm, rainy day and low pressure, algae are easy to die, which leads to deterioration of fertilizer and water, lack of oxygen in water, and fish are not suitable for fishing. muddy water

This kind of water contains a lot of sediment and humus. The water is yellow-brown, and the visibility is within 5 cm. Most of them are caused by sediment rushing into rivers, ponds and reservoirs after heavy rain. In addition to pollution, muddy water generally contains a lot of oxygen and food, but too much sediment makes it difficult for fish to breathe and escape into clear water. Only small fish like catfish take the initiative to eat, and most of them feed on running water. Therefore, it is difficult to catch fish such as Fushou, crucian carp, carp and green grass in muddy water. sewage

The water polluted by industrial wastewater or domestic wastewater is generally black, soy sauce color, brown, dark blue and red, and a few of them are very clear, but the smell is pungent. These waters contain too much acid, alkali or chemical harmful substances, such as mercury and industrial oxides. In severe cases, there is no living thing in the water, and in light cases, there are few fish. Abnormal growth, strange color, peculiar smell, no fishing. In addition, turbidity is also closely related to literary sentiment. The place with suitable turbidity is the place where fish "feel comfortable" and are happy to feed. If the turbidity of water is divided into 1 1 grades from 0 0- 10/degree, the water with clear water is 0 degree and saturated mud is 10 degree, then the turbidity of the most suitable water for fishing should be between 4-6 degrees, that is, it is not clear or mixed. In such turbid water, aquatic plants can be seen faintly at 0. 15-0.3 meters below the water surface. But it should be noted that even in the same water area, the water color is often different from place to place. To fish in such waters, you should choose a fishing position with ideal water color and turbidity. Second, observe the blisters.
