How to prevent birds in loach farming? How to prevent loaches from escaping

Bird repellent devices, bird repellent sticks, bird repellent agents, laser bird repellent and bird net can be used to prevent birds.

1. Bird repellent.

The intelligent bird repellent device is an ultra-low power intelligent bird repellent device made by using imported single-chip microcomputer design, integrating Doppler radar detection bird proximity technology, pickup detection bird call, ultrasonic bird repellent technology, simulated eagle sound source bird repellent, simulated shotgun gun repellent bird, night strobe strong light repellent bird repellent and other technologies.

2. Anti-bird sticks.

The anti-bird rod is generally a long spiral, covered with a coating layer, which rotates under the blowing of the wind, and then the coating reflects the sunlight, thereby preventing bird damage. Bird sticks are very popular in areas with high plant coverage and environmental friendliness to prevent bird damage without harming birds, and they are also very aesthetically pleasing to rotate themselves.

3. Bird repellent.

Bird repellent is generally made of pure natural raw materials (or equivalent to natural raw materials), processed into a biological agent, after the use of distribution, slowly and persistently release a special fragrance that affects the nervous system and respiratory system of birds, and the birds will fly away after smelling, and will not come back during their memory period.

4. Laser bird repellent.

Laser bird repellent is a green laser with a wavelength of 532nm and a power of 500MW to repel birds. The laser bird repellent works at dusk, night, and until early morning, and theoretically tests that the laser bird repellent is still effective when the outside light is lower than 15,000 lux.

5. Anti-bird netting.

Anti-bird net is a kind of mesh fabric made of polyethylene and healds with chemical additives such as anti-aging and anti-ultraviolet rays as the main raw materials, which is made of wire drawing, which is covered on the scaffolding to build an artificial isolation barrier to keep birds out of the net, cut off the breeding route of birds, effectively control the spread of various birds and prevent the spread of viral diseases.

There are several ways to prevent birds,1The overall net over the pond is pulled over, which is a bit expensive and inconvenient to operate the pond; 2.Set up an anti-bird net on the edge of the pond, a few trees can be used, and birds such as egrets can be hung, but it seems to have little effect on some birds living near the water; 3.

Pull a fishing line over the pond, with an interval of about 1m, so as not to harm the bird and help protect wild animals; 4.Watching CCTV, a friend tied firecrackers with mosquito coils, and when they burned somewhere, they could ignite the fuse and fall down** to scare the birds; 5.Scarecrows, geese, shouting, etc. all have a certain effect.

Loach breeding should have pond conditions, water quality conditions and other conditionsRaising loaches should be clearedSilt disinfection, feed selection, daily management and other aspects to raise.

1. The conditions for raising loaches.

Pond conditions: the seedling cultivation pond area is about 600, the pond Nianchun oak depth is about 50, the cultivation pond is best to be an earthen pond, the soil at the bottom of the pond should be tamped, and some grasses (such as ryegrass, reeds, etc.) can be planted around the shore around the shore about 1 for shading. Before the seedlings are planted in the pond, the whole pond is splashed with Shengsen clear lime (150kg mu), and when the pond water is green, the seedlings can be put in.

Water quality conditions: When breeding loaches, although the requirements for water source are not very high, the water source should not be polluted. Therefore, the water quality should be clean, and the pond should be close to the water source, so that it can be convenient to add water to it later.

The depth of the pond water does not need to be much, almost 40 to 50 centimeters.

2. How to raise loaches.

Dredging and disinfection: The pond must be cleaned of silt, and then exposed to the sun after cleaning. Generally, 30 days before the loach seedlings enter the pond, they should be exposed to the sun, and the bottom of the pond should be dried into a turtle back shape, which can destroy the microorganisms in the pond.

About a week before stocking loach seedlings, quicklime can be used for disinfection.

Feed selection: loach is omnivorous small fish, feed ** is very wide, daphnia, earthworm, fly maggot, etc. are natural bait organisms of loach, under artificial breeding conditions can be fed rice bran, soybean cake, bean dregs, blood meal, wheat bran, etc. The daily feeding amount of loaches was 1% of the total weight of loaches in March, 4% of the total weight of loaches from April to June, 1% of the total weight of loaches from July to August, and 4% of the total weight of loaches from September to October.

Daily management: to achieve "two prevention, two diligence, three morning, four looks", that is, to prevent escape, disease prevention, diligent patrol, diligent diary, early pond clearing, early food, early stocking (prolonging the loach growth period), look at loach activities and feeding, look at weather changes, see water quality changes, look at seasonal changes and so on to determine the amount of feeding.

Morphological characteristics of loaches

The body is elongated, cylindrical, and the caudal peduncle is flattened and thin. Small head. Snout tip.

Lower mouth, horseshoe-shaped. 5 pairs of whiskers (1 pair of snout whiskers, 2 pairs of maxillary whiskers, 2 pairs of mandibular whiskers). The eyes are small, laterally superior, covered by paraepithelium, without infraocular spines.

The gill aperture is small, and the gill slit terminates at the base of the pectoral fin. The scales are very small and deeply embedded in the skin. The siding line is complete.

Lateral line scales are more than 150. The swim bladder is small and enclosed in a hard bony sac. The dorsal fin is short, the starting point is opposite to the beginning of the pelvic fin, with unbranched fin bars 2 and branched fin bars 7.

The pectoral fin is distantly from the pelvic fin, with unbranched fin bars 1 and branched fin bars 10. The pelvic fin does not reach the anal fin, with unbranched fin rays 1, branched fins 5-6. Anal fin with unbranched fin 2 and branched fin 5. The caudal fin is rounded.

The upper part of the body is grayish-brown, the lower part is white, and there are irregular black spots on the sides of the body. There are also spots on the dorsal and caudal fins. There is a large black spot above the base of the caudal fin. The other fins are grayish-white.

Loaches are good at escaping, when the fish stopping equipment is damaged, the pond ridge collapses or there are small holes and cracks open to the outside, and when there is overflow during the flood season or heavy rain, the loaches will escape with the water or burrowing. In particular, loaches are kept at high densities in ponds, and even if only a small flow of water flows into the ponds, the loaches can escape against the current, often half or more overnight. Therefore, pond-raised loaches should pay attention to the prevention of escape, and the following points need to be paid attention to to prevent loaches from escaping.

1. When cleaning the pond, remove the weeds on the pond ridge, tamp and strengthen the pond ridge to avoid collapse and cracking due to pond water immersion.

2. Strengthen pond patrols. During the feeding period, the weeds on the ridge should be cut frequently, so as to check whether the ridge has a small hole or crack to pass out, and if there is, it should be blocked immediately; Whether the fish stopping equipment at the inlet and drainage outlet is damaged, once it is damaged, it should be repaired or replaced in time.

3. In the flood season or heavy rain, it is necessary to take the initiative to discharge the pond water, fix the pond ridge, dredge the inlet and drainage outlets and channels, and avoid overflow and escape from fish.

Fourth, the rice field breeding loach anti-escape measures:

An 80-centimeter-high escape wall was built around the paddy fields with cement or plastic sheets, films, screens, etc. (30 cm into the mud). Build a 20 cm wide step along the ridge, 15 cm from the top of the ridge. Around the field and ** dig a "field" shaped ditch, ditch width, depth of 50 cm.

The inlet, drain pipe and overflow pipe each have one mouthpiece, and the nozzles are intercepted with fine barbed wire, and the drainage pipes are usually sealed with cement.

Cover the lid and seal it.

Before putting seedlings, the pond should be thoroughly cleared with quicklime or bleaching powder, and after 1 week the water toxicity completely disappears, the seedlings can be released, and several loach seedlings are put into the water test in advance before the seedlings, there is no abnormal reaction within 4 8 hours, and the loach seedlings can be officially put into the pond, and the water depth of the pond is generally kept at 30 50 cm. In particular, in ponds with high breeding density, water pollution needs to be changed, and cannot be directly discharged. It should be concentrated in the pond purification treatment prepared in advance, and the purification pond should be properly put with silver carp and silver carp, planted with aquatic vegetables or aquatic plants, combined with disinfection and microbial purification, and recycled for production after the water quality is qualified.

There are many natural enemies of loaches, some large wild trash fish, centipedes, snakes, mice, water birds, etc. in the water are very harmful to loaches, so if you want to breed loaches, these hazards must be prevented, for the water swimming, running on the ground This good prevention, at most is the fish pond is thoroughly disinfected, surrounded by nets, after the purchase of loach seedlings should be put into the pond in time, 10 to 15 days after stocking do not need to be fed, corn flour, wheat bran, egg yolk, bone meal, shell powder and other small particle shape of feed can be fed, Feeding is mainly done at night.

Fertilizer can be manually applied to supplement, the depth of the pool is about one meter, and the water depth is kept at about 50cm. In the early stage of breeding, the pond should be disinfected with quicklime or bleaching powder, and it is best to place some supported planks and branches in the pond to facilitate the gathering and fishing of loaches in the future.

The depth of water in loach ponds should be controlled between meters. This water depth is the most suitable water depth for loaches to grow. Loaches belong to the bottom fish in terms of living habits, and almost all the nutrients needed for growth come from the soil, so they need to be fertilized with water!

It mainly occurs between the splash and 2 3 cm, and the high chance of mortality is that there is no cure, and the manifestation is that the belly is upward, and the main ** is that the dissolved oxygen is too high. 2.Insects, the main damage is the wheel worm, mainly occurs in more than 3 cm.

When stocking loach seedlings, pay attention to sealing the edge of the field, otherwise the loaches may burrow into other places. In addition, it is also necessary to pay attention to the sufficient nutrition in the field so that the loaches can grow quickly.

First, buy loach seedlings of the right size, generally 3 to 4 cm is more suitable; second, place an oxygen generator in each pond to ensure that oxygen is sufficient; Third, choose the right time for stocking, generally mid-May is the most suitable.

It is necessary to observe the condition of loach seedlings every morning, noon and evening, to prevent wheel diseases and insects with drugs in advance, and to ensure that the water quality is fertile and clean.

Stocking management needs to pay attention to the density of stocking, and in this process should also pay attention to feeding in time, so that the loach can grow better, and must pay attention to the density.

When breeding loaches, we must control the quality of water quality, do not have pollutants, the appropriate amount of new water and fertilizer will reproduce faster, and the pond should be cleaned regularly, the best time for breeding is in mid-May, and 10,000 fish fry can be put per mu.

Be sure to pay attention to the density of stocking, and the time of stocking must be noted, and the feeding during the breeding period also needs to be matched according to the situation, and must pay attention to disinfection.

When breeding, it is necessary to keep the water surface clean, and the management of feed must be strengthened, and guardrails must be set up to prevent loaches from escaping.

Always inspect the fish ponds. Pay attention to the temperature of the water. Watch out for other predators. Pay attention to the oxygen in the water. Give him medication promptly**.

The water temperature should never be too different. Wait for the loach seedlings to get used to it before putting it in the tank. Be sure to spread the loach seedlings when they go into the water, and don't clump them together. Be sure to spray and disinfect the inside of the sink regularly. Feed some suitable feed.

Pay attention to the selection of ponds, as well as the management technology of fish fry, but also pay attention to the feeding of feed, but also pay attention to the selection of water quality, and combine scientific methods for management.

It is necessary to pay attention to the water temperature, and also to often clear the enemy, harm and frequent patrols, must do a good job of these three tasks, the best patrol is once in the morning, once at noon and once in the evening, and then to observe the change of water color. If there are some floating heads, then the water should be overfertilized and should be stopped immediately. Fertilization should not be continued.

Avoid such a hot season in the summer. Try to control the temperature of the water, and control the temperature, about 30 degrees to 32 degrees. And there are many natural predators, such as dragonfly larvae, water snakes, rat water, centipedes, and so on.

It is necessary to regulate the water temperature of the breeding ponds, to do a good job of removing predators, and to carry out patrols three times a day.

Be sure to pay attention to the cleanliness of the water quality, and be sure to remove some bacteria and impurities frequently, and be sure to pay attention to the water temperature, the water temperature must be kept above 10.

First of all, the land should be managed in a planned manner, and secondly, some things should also be controlled, otherwise it is easy for the loaches to run around and affect others.

These loaches should be observed every day, and the water temperature should be adjusted to remove their natural predators, and care should be made that the water does not contain too much fertilizer.

To prepare for seedlings, the environment and bait requirements are higher, the water temperature should be appropriate, lower than the water temperature of the seedlings, and the seedlings must be put slowly and gently.

Loach breeding is everywhere, including ** or something, putting 200,000 tails per mu, deceiving you to buy seedlings, and then promising **price of about 15 yuan**, and finally losing all your money.

Pond breeding loach, can be selected close to the water source area, the area is 200-400 is appropriate, the pond water depth is 40-50 cm, the water quality is acidic, the bottom of the pond is flat and the silt is less. Before the seedlings are planted in the pond, it is good to use quicklime and bleaching powder to mix the pond for disinfection, and the water depth is about 10 cm, and 50 kg of quicklime plus 15 kg of bleaching powder are used to dissolve the whole pond and splash it.

There are these points that need to be paid attention to in the cultivation of loaches: when farming in ponds, loaches like to move at the bottom of the pond, and only float to the surface of the water to breathe air when the air pressure is low and the dissolved oxygen in the water is insufficient; The suitable water temperature of the loach is 15 to 30 degrees Celsius, when the temperature is higher than 30 degrees Celsius or below 10 degrees, when the pool water dries up in winter, the loach will burrow into the soft mud, rely on a small amount of water to keep it moist, and rely on constant breathing to maintain life; The stocking amount of loach is 20,000 to 30,000 per mu, if it is a loach seed pond with deep water and fertilizer, you can also mix a small amount of silver carp, in the process of feeding, you should put manure, vegetable scraps and grass, and if you have the conditions, you can feed rice bran, bran fishmeal or bait. Its advantages are that loach has strong adaptability, wide bait, convenient management, and is suitable for rural family breeding.
