What are the reasonable feeding methods for fish feed?

First, the choice of feed grade.

It is suggested that fish farmers should take the break-even analysis of feeding as the key basis, and when the price of a single catty of fish does not exceed the cost of a single catty of fish feeding, it is advisable to choose low-grade feed; When the price of a single catty of fish is higher than the cost of a single catty of feeding, it is advisable to choose high-end feed, and the higher the grade, the more cost-effective it is.

Second, the selection of feed pellet diameter.

The size of the diameter of the feed pellet is generally 1 4 2 3 of the vertical length of the fish species, and then the actual selection is based on the original size of the fish. For example, carp with a large mouth fissure can choose a slightly larger vertical mouth fissure, accounting for 1 2 2 3;White fish, bream, crucian carp, etc. are slightly smaller, accounting for 1 4 1 3. The height and diameter of the feed also depends on the actual species, generally in:

1。Therefore, before purchasing aquatic feed, we must first figure out the size of the fish, and according to the size of the fish body, effectively clarify the suitable feed particle diameter. In this way, it is not easy to cause feed consumption and does not harm the feeding of the fish.

Third, the choice of feeding method.

1. The necessity of domestication.

Fingerlings are generally required to be domesticated to the river surface and adjusted for centralized feeding, and then gradually feed normally. The taming method can be flexible and varied, and most of the time is 3 10 days, and the maximum is not more than half a month, that is, the taming can be successful. Many people find it inconvenient to tame food or even unwilling to tame, or lack of care, and fail to tame.

I don't know what the growth of the fish is, the production cost budget, etc. The benefits of domesticated fish feeding include: the ability to immediately observe the growth and development of the fish, the size of the size, the selection of commonly used feed types, the diameter of the particles and the effective grasp of the amount of feeding; According to the market trend and economic benefit cost budget, flexibly manipulate the growth and development rate of fish, and sell moderately to get good profit income.

From this, the need for domestication is obvious.

2. Pay attention to feeding methods.

There are many aspects of feeding methods, such as: feeding speed, feeding area, feeding frequency, and the placement position of the automatic feeding machine. The feeding method should be flexibly mastered and adjusted according to the specific situation.

For example, under the group culture method of large grass carp, bream and crucian carp, carp compete for food quickly and have a large appetite, and bream and crucian carp eat "Sven", if you do not pay attention to the improvement of feeding methods (feeding rate increase, feeding time reduction, etc.), bream and crucian carp will not grow much. Fish farmers should always think about the feeding method and the actual effect of feeding, so as to take certain effective measures immediately to adjust the unreasonable feeding method to improve the economic benefits of feeding.

When feeding, it is necessary to eat less and feed more, one time should be slightly less, but you should pay attention to feeding several times, you should choose a fixed time every day, and you should also choose some feed that is in line with their growth, as far as possible to have some higher nutritional value.

It is necessary to pay attention to a time when feeding, it is best to feed regularly every day, and at the same time, when choosing dietary therapy, you should still choose some higher nutrition, feed less each time, and feed more times a day, so that he can grow particularly well and be able to lay eggs.

The reasonable feeding method of fish feed is to choose the right feed, each kind of fish needs different feed, we have to choose a suitable fish feed, so that the fish will grow healthily.

It is necessary to pay attention to the quality of feed, but also to pay attention to the collocation, but also to pay attention to the choice of methods, should also pay attention to the skills of breeding, to master the method of feeding feed.

<> "Buy feed to choose good reputation, good technical services, suitable and stable company bench containing food, these companies have strong financial and technical strength, to ensure that the feed production formula and nutrition balance, is conducive to the digestion and absorption of breeding objects, promote the growth and development of breeding objects, and ensure the company's technical services. However, they also offer technical breeding services to provide scientific guidance on animal feed in order to get the most out of the economics of fish feed.

When selecting granular materials, it should be noted that the diameter of the particles containing the intention should be consistent with the size of the opening of the breeding object, so as to facilitate the normal feeding and intake of the breeding object; Secondly, the amount of spraying of granular material should not be too high, which indicates that the adhesive is insufficient and the processing is not very good. Particulate matter is easy to release in water, poor stability, not conducive to fish feeding, fish feed particle size is generally between, basically two-thirds of the longitudinal length of the crack in the mouth of aquatic fish. If the longitudinal length of the crack in the mouth of the breeding object is 9-mm, it is suitable for feeding animals with a particle size of 6-mm, which does not cause waste and does not affect food.

In general, the best features have bright brightness and consistent colors. The sensory index reflects that the crushing strength of the compound feed is good, the processing technology is reasonable, and the fineness of the feed raw materials is high. Good crushing thickness is good for the digestion and absorption of fish and shrimp, which is different from animal feed and poultry.

All types of feed have specific smells and tastes. For example, due to the use of fishmeal, good fish feed usually has a very normal fishy smell, which is more pleasant. If it is a bad diet, because some fishmeal substitutes are used, then whether the fishy smell is weak.

Fish feed is fed with water, which is different from animal feed. Water-fed food needs to have a certain time stability to prevent nutrients from dissolving in the water, which is conducive to concentrating fish feed, improving food efficiency, reducing feed costs, and preventing water quality from deteriorating. Once the splash enters the pond, feeding usually begins the next day.

Due to the low active feeding capacity of the splashes, they are usually sprayed with soy milk. Some thin soy milk can be fed directly through water splashes, and most of them are used to fatten jujube old laughing water. With water and fertilizer, abundant algae and daily life can provide adequate nutrients for fried fish, especially rotifers are suitable for the opening of fried fish, which is a nutritious food.

The reasonable selection and feeding of fish feed should pay attention to the color, smell, particle shape, feed grade, feed composition, and feed dosage.

It is necessary to pay attention to the amount of feed, pay attention to the composition of the feed, try to choose compound feed, and add some nutrients.

It is very important to pay attention to the problem of balanced nutrition and choose the right feed, so that the fish can grow better and avoid many diseases.

1. The diameter of pellet feed fish pellet feed is usually 8 mm and 5 mm 10 mm long, which can be directly cast in the fishing pond for feeding. Do not feed the feed directly when it is damp, but dry it or dry it before feeding; If the feed is spoiled, it should not be fed again to prevent fish poisoning after eating.

2. Cake feed, cake feed feeding small fish should be crushed, soaked, ground and fed, and fed to large fish to soak them.

3. Grains such as corn with large grains should be processed and crushed to feed fish; Small grains such as grains, can be germinated and fed to fish, young grains white buds have high nutritional value, fish eat easy to digest, fast absorption, fast weight gain.

4. Green feed for medium to large fish, generally after removing the soil, the green feed can be fed directly; To feed small fish, they should be chopped or pulped, mixed with salt, and sprinkled with feeding. Chop the green fodder and cook it, mix in an appropriate amount of bran and soda, and small fish prefer to eat it.

5. The bran feed should be soaked and ground when feeding small fish; If you feed medium to large fish, it is advisable to ferment them until they have the aroma of wine. At the beginning of feeding, a small amount of feeding, and then gradually increase the amount, but should not exceed 30 of the total amount of feeding per day.

6. Protein feed earthworms, maggots, insects, etc. are the best animal protein feed for fish, which can be fed directly, or dried and processed into powder and fed to fish with other feeds. For lumpy animal feed lead ears, they should be chopped and ground finely, and a binder should be added to make small balls to feed.

There are three types of feed that can be fed to fish farming, which are animal feed, plant feed and synthetic feed. Among them, animal feed includes water, rotifers, daphnia, earthworms, maggots, etc., and plant feed in addition to aquatic weeds and algae, you can also choose some vegetables, but you can only feed them after scalding and cutting them into cubes. Synthetic feeds are flakes and pellets, the former for upper and middle pelagic fish, and the latter for demersal fish.

Animal feed is preferred for fish farming. This feed has a high protein content, which not only the fish love to eat, but also helps to grow. The usual animal feeds include water flow, rotifers, daphnia, water earthworms, fly maggots, harvest shrimp, silkworm pupae and so on.

Some of these foods do not need to be processed and can be fed directly, while others should be broken and fed, and the amount should not be too large, otherwise it is easy to spoil the water.

Plant-based feeds are more suitable for some herbivorous fish, and for omnivorous fish, it is also an optional food. In addition to aquatic plants and algae, common plant-based feeds also include vegetables, but they cannot be fed directly to the fish, so they need to be processed and diced after they are blanched, and the size should be controlled to ensure that the fish can swallow. It should be noted that this kind of feed cannot be fed alone, and it is best to use it with some animal feed.

Synthetic feed is a variety of fish food that can be bought on the market, and generally has a detailed ingredient list, which is very helpful for the development of fish, and some can also promote their color. It should be noted that synthetic feed is divided into flakes and pellets, the former will float on the surface of the water and is very suitable for some upper and middle pelagic fish, and the latter will sink and be suitable for some fish that live on the bottom.

There are many types of fish feed in <>, and generally all the feed that can be used as livestock and poultry can be used for fish feeding.

1) Plant-based feed. There are 3 categories: one is energy feed such as corn, bran, fine bran, barley, wheat, etc.

The other category is protein feed such as soybean cake, peanut cake, cottonseed cake, rapeseed cake, sesame cake, beans, etc., as well as by-products. There is also a variety of green fodder such as alfalfa, ryegrass, Sudan grass, various wild weeds, aquatic fodder, etc.

2) Animal feed. Animal feed is mostly high-quality protein feed, which has a high cost of use, but a better effect. Such as fish meal, blood meal, silkworm chrysalis powder, meat and bone meal and zooplankton.

3) Mineral feed. Mineral feed is mainly to provide macromineral elements. Such as dicalcium phosphate, stone powder, bone meal, zeolite powder, maifan stone, etc.

4) Additive feed. Provide a variety of trace ingredients such as trace element additives, vitamin additives, binders, attractants, Shichong colorants and some drugs, in addition to the above feed, can also use fly maggots, earthworms, insects and by-products of food factories such as vermicelli factories, starch factory scraps and processed saccharified fermented feed.

<> specific polyculture fish feed preparation needs to be determined according to the actual breeding scale and breeding species, the general formula can choose to use rice bran 40%, bran 38%, soybean cake 10%, fish meal 10%, yeast powder 2%, feed coefficient of feed, and add some green feed, feed coefficient can be.

1. Polyculture fish feed formula

Generally, you can use 40% of rice bran, 38% of bran, 10% of soybean cake, 10% of fish meal, 2% of yeast powder, the feed coefficient is, at the same time, you can also add some green fodder, the feed coefficient is appropriate, you can root the root rot according to the actual breeding situation to carry out the reasonable preparation of the clear base, such as the size of the breeding scale and the different breeds of breeding to decide, generally this formula is suitable for most polyculture fish.

Second, the amount of feeding is appropriate

1. Annual feeding amount: to be calculated according to the net weight gain multiple of the fish and the feed coefficient, the general net weight multiple of the fish is 4-5 times, and the feed coefficient of the full price compound feed is the multiple, and the mixed feed is the multiple.

2. Monthly feeding: Usually in March, the feeding amount is 1% of the annual feeding amount, the annual feeding amount is 4% in April, the annual feeding amount is 8% in May, the annual feeding amount is 15 months in June, the annual feeding amount is 20% of the annual feeding amount in July and September, the annual feeding amount is 9% in October, and the annual feeding amount is 3% in November.

3. Daily feeding amount: 80% of the daily average of feeding in the first half of each month from March to August, the average daily feeding in the middle of the month, 120% of the average daily feeding in the second half of the month, starting from September, 120 of the average daily feeding in the first half of the month, the daily average in the middle of the month, and 80% of the daily average in the second half of the month.

Aquarium fish Some fish lovers often die because they love fish and feed them a variety of excessive bait. As everyone knows, fish are not easy to starve to death and are prone to swelling to death, or fish death due to excessive bait causing water quality to deteriorate.

First, the focus of feeding bait.

Generally, compound feed is more suitable to be fed twice a day from 9:00 a.m. to 10:00 a.m. and from 4:00 p.m. to 5:00 p.m. Feed fish insects.

The live bait can be cast at one time in the morning, and the larvae should ensure that there are rotifers and paramecium in the tank.

or egg yolks and other open baits.

Suggestions: Investment must follow the four principles of timing, fixed-point, qualitative and quantitative.

Second, the basis of the daily bait.

The daily amount of bait can be about 2-4 of the total body weight of the fish or 30-60 minutes after the bait is eaten as the standard for comprehensive judgment.

3. Environmental impact of feeding.

When specific bait, it should also be appropriately increased or decreased according to the season, climatic characteristics, water temperature, water quality differences, and fish feeding intensity.

Fourth, it is recommended to go out for bait.

If you can't feed every day when you go out, just feed and change the water before going out to ensure that the water quality is clear and the oxygen is sufficient, and the hunger for a few days has no effect on the health of the fish.
