Method 1: Throw the dough mixed with Kaempferia Kaempferia powder (as big as longan) into another place underwater (preferably downwind, not too far away). Because the smell of Kaempferia kaempferia is very attractive to prawns (the bait used for fishing can't be mixed with it, otherwise it will attract prawns), when the prawns smell this smell, they will soon swim to the dough to nibble. This method has been tried and tested repeatedly.

method 2: you can buy trichlorfon for flowers in the flower market, put a piece the size of a tablet in the nest and throw it into the den, which can also ensure that the shrimps will not make nests. Because the fish ponds are all disinfected with flowers and trichlorfon, there is no need to worry about any harm to fish and people who eat them.

Fishing skills:

Low-pressure weather is a very important factor that affects fish's eating, and it is also often encountered by fishermen. Its main formation and forms are as follows:

1) The weather is sultry, there is no wind, the water surface is still, the fish languish in the water, and they don't want to eat. As the fishing proverb says, "Water is not enough."

2) It rains in spring and clears up in winter. The fog lingers for a long time, resulting in no wind and low air pressure, and the fish sink to the bottom of the water and rarely move.

3) The southeasterly wind makes the moisture in the atmosphere increase and the air pressure decrease, so the water body can't absorb oxygen from the atmosphere, and the water is seriously deprived of oxygen. The fish feel extremely uncomfortable at the bottom of the water and have to float their heads to breathe.

After understanding the reasons why fish don't bite the hook in low-pressure weather, there are countermeasures:

1) Find a place with water flow (such as the inlet and outlet in a pool or pond) to get off the hook, which can increase the oxygen content in the water.

2) When fishing in shallow water or where there are aquatic plants and trees, the water in shallow water has a fast convection and high oxygen content, and the dissolved oxygen in aquatic plants and trees is higher than that in other waters due to photosynthesis.

3) The flowing water body is rich in oxygen, which is the first choice for fishing in low-pressure weather.

the bait is not right for the fish? The importance of bait in fishing is self-evident. There are several reasons why baited fish don't eat it:

1) In some fish ponds, fish have formed a certain deviation due to artificial long-term feeding of certain fish feed or food (this is the most common in fish ponds fed with granular bait). If fish are used to fishy, if you use fragrant bait to fish, the fish will not bite. 2) Fish in some natural waters are restricted by food sources, and they also tend to be partial to certain foods. You can't get what you want, and it's hard to get anything.

3) The composition, taste and state of the bait used in the fishing competition are not suitable for the fish to eat, which will also cause the fish not to eat. 4) Fishing with contaminated bait (if your hands come into contact with something that smells like gasoline, it will directly pollute the bait) or deteriorated bait will cause fish to refuse to eat.

Countermeasures:

1) When fishing in the fed fish pond, try to fish with the original pond granules. If the original pond granules can't be found, the taste of the commercial bait should be close to that of the fed fish.

2) When going out fishing or going to a competition, you should bring more baits with different properties (it is best to bring all kinds of meat and vegetables), and then find out the bait suitable for fish feeding according to the trial fishing.

3) Pay attention to details to avoid bait pollution. When fishing, the bait is now in use, and the deteriorated bait is not needed.

the change of water level has a great influence on fish feeding, and the fluctuation of water body has obvious influence on fish feeding. In the rainy season in rivers, reservoirs and other waters, fresh water is constantly injected into the water body, and at the same time, it brings a lot of organic food to the water body. In addition, the dissolved oxygen in the water increases, and fish move frequently, foraging everywhere, and the food intake increases greatly.

when retreating or discharging water, due to the change of the food chain in the water, some of the original food is lost, and the intermediate food is interrupted, which causes the fish to panic, and they will swim to the deep water without any intention to find food.

another thing that deserves our attention is that in high-density intensive fish ponds, the water remains stable for a long time, and the dissolved oxygen in the water is getting lower and lower due to the continuous consumption of oxygen by fish breathing, or the water quality in natural waters has not changed for a long time, resulting in "stagnant water", which will cause hypoxia in the water and fish will not eat.

because the change of water body affects the fish's feeding, we can use the two fishing proverbs "It is better to fish before rising, not after falling into the water" and "fishing while rising, fishing while retreating" to deal with it.

fish don't eat water after disinfection? Usually, in order to treat fish diseases, or fish in what we call a "black hole" where the fee is charged by the sky, and the fish pond owner does something, chemicals such as ammonium chloride, bleaching powder and quicklime will be put into it, which is decisive to affect the fish's intake.

1) Ammonium chloride is a kind of chemical fertilizer, mainly a disinfectant. As long as all the fish choked by it float on the water surface, they don't eat at all and jump on the water surface from time to time. 2) Bleaching powder, the scientific name of which is "calcium hypochlorite", is used for water purification and fish disinfectant. When it enters the water, the fish will not eat, and the water quality will become clear. At the same time, the fish can't stand the large amount of chlorine gas in the water, which makes the fish fidgety and disorderly.

2) bleaching powder, the scientific name of which is "calcium hypochlorite", is used for water purification and fish disinfectant. When it enters the water, the fish will not eat, and the water quality will become clear. At the same time, the fish can't stand the large amount of chlorine gas in the water, which makes the fish fidgety and disorderly.

3) quicklime, whose scientific name is calcium oxide, is also a water purification agent and disinfectant, and also a water quality neutralizer. It is used to adjust the PH value of water, that is, the pH value. If it is put into water, fish will not eat it.

do fish refuse to eat when they are breeding or sick? Every year, fish have a reproductive incubation period, during which they are busy laying eggs and reproducing their offspring, and have no intention of foraging. However, some time before and after the breeding period, fish will consume a lot of food to maintain or supplement the energy consumed by spawning, and there will be a feeding peak. ?

However, once fish get sick, their appetite will decrease, especially gill diseases, which can make fish have difficulty breathing, greatly reduce their food intake or hunger strike. There is nothing to be done about fish not eating because of illness.
