How can fish farming be used to maximize fish production? Is there any advanced method?

Farming is the first step for many farmers to increase their income, after all, many farmers have more fields at home, so through farming can bring better income to themselves and their families, and now the good thing to do in farming is to raise fish, shrimp, and livestock, which we often see in farmers waiting for these things. There are several suggestions for improving the efficiency of farming, especially fish farming.

1. Original ecological fish farming.

In fact, it is best to raise fish in the original ecological environment, after all, the growth process of fish still likes to be in the most primitive environment, such as digging the ground at the edge of their own fields can expand the scope of fish farming, and then there is the most primitive soil infiltration to revise the edge of the field slightly, the fish raised in this environment is the most lively and ecological and primitive, and many merchants in other regions like to buy the original ecological fish, the taste of such fish is very good, and the effect is not unique, At present, many farmers will choose the original ecological fish farming, after all, the yield is high, and the fish is the best.

2. Freshwater fish farming.

Freshwater fish farming is also more suitable for improving the yield method, according to the life characteristics of different fish will be the fish species in proportion to make full use of the water in the fish pond, so that the water is more abundant, at the same time the fish in the water body, if the living habits are different, can make full use of young children, reduce the cost of feeding, improve economic benefits, freshwater fish farming is generally necessary to keep the water clear, not too salty, to have a freshwater effect, The main technical feature is that the freshwater fish are polycultured according to the upper, middle and lower or bottom three kinds of fish, so that all kinds of fish are clearly cultured, and the material will be too large when placed in each layer, and if the polyculture will appear to be somewhat unadaptable, the fish will die.

3. Fish farming in greenhouses.

Greenhouse fish farming is also a better technology, after all, in recent years, greenhouse fish farming has been one of the methods that many farmers want to choose, because the cost and technology involved in greenhouse fish farming is relatively high, and can provide constant temperature effect, such aquaculture is actually able to improve better yield, after all, the living environment of the fish also needs the temperature and the surrounding environment to cast, only in this way can we improve the better effect of breeding, just say that the cost of your greenhouse fish farming may be a little higher.

When breeding, we should also pay attention to an environmental problem, so we should ensure that the water is particularly clear, and we also need to choose some better varieties, and then choose some good feed, which needs to be replaced regularly, so that the yield can be more, and it can also be put in the way of an aerator.

There are advanced methods, at this time you can choose the method of mechanical breeding, and you must find a particularly good geographical location, and then pay attention to the depth and width of the pool, and then you must choose some fish fry with a relatively high survival rate, and you must pay attention to ensure the oxygen of the soil, you must replace the water resources in time, and you should also choose exquisite feed.

Be sure to choose the right species of fish for breeding, can be polycultured, but must be carried out in accordance with the scientific ratio, pay attention to the breeding density, pay attention to the feeding of feed, pay attention to the situation of the pond.

First of all, we should choose high-quality water sources, and at the same time, we should regularly replace the water to improve the oxygen content of the water quality, and we should choose some excellent bait, learn professional breeding techniques, and we should choose some more high-quality varieties.

As an important part of China's aquaculture industry, fish farming is mainly divided into pond fish farming, rice field fish farming, reservoir or lake fish farming, artesian water fish farming, and open circulation flow aquaculture. Next, let me introduce to you in detail the specific operation of these methods and what are the advantages and disadvantages of each.

First, pond fish farming.

Pond fish farming is a traditional way of fish farming, the main operation is to clean the fish pond before Yang Yuzhen, pay attention to the pond at the beginning of the pond should not have aquatic weeds and silt, because these will affect the water quality of the pond. It is advisable to apply natural bait in subsequent management to promote the circulation of the pond ecosystem. The biggest disadvantage of pond fish farming is that it pollutes the environment, and the sewage in the pond cannot be recycled.

Second, fish farming in rice fields.

The main operation of fish farming in rice fields is to increase the ridge of the rice field, and then add a net at the drainage outlet to prevent the fish from running away, and finally dig a pit in the rice field to increase the space for fish to move. Rice and fish farming also belong to the traditional way of fish farming, which consumes a large amount of environmental resources and does not conform to the development trend of modern aquaculture.

Third, artesian water fish farming.

Artesian water fish farming is the use of water level difference to raise fish, it should be noted that we rely on the water level difference to increase the solubility of water when artesian water fish farming, so the opening should be set up on the shore as much as possible. The main advantage of artesian water fish farming is that it is economical and simple, but it is necessary to pay attention to the prevention and control of fish diseases.

Fourth, open circulating flow aquaculture.

Open recirculating water farming refers to the pumping of water into the pond by relying on external power, and then pumping the water from the pond after raising the fish and allowing it to return to the natural waters. The main advantages of this breeding method are less land occupation, short breeding cycle, high yield per unit area and so on.

Fifth, fish farming in reservoirs or lakes.

Reservoir or lake fish farming refers to large-scale fish farming in natural reservoirs or lakes. The main characteristics of this method are the spaciousness of the water body, the fertile water quality, the high and low water level, and so on.

I have introduced so many ways to farm fish, and I hope I can help you.

The breeding method of fish farming is that it can be cultivated in fish ponds, fish ponds, plastic bottles, fish tanks, or crockpots. The advantage is that the breeding process is relatively simple, the survival rate of fish is relatively high, and the cost of breeding is relatively low, and the disadvantage is that it may lead to a relatively high mortality rate of fish, which will cause fish to have no nutrition, and will cause fish to die more easily.

First of all, we should choose a good breed to feed, learn the technology of breeding, and then we should also give regular replacement of water, keep the oxygen in the water sufficient, be sure to prevent diseases in advance, and clean the fish tank regularly, which is very ornamental. Or it can be farmed on a large scale, which can obtain very good economic benefits.

Through fish tank farming, ancient farming, scientific and technological farming, fish tank aquaculture is better managed and water quality is better determined. The ancient method of farming is healthier, and the fish will be more lively. Science and technology breeding should be more advanced and can better determine the problem.

1.Stocking of instar grass carp fingerlings that had been vaccinated in the previous year was selected.

In order to improve the survival rate of grass carp breeding, in the past few years, they have passed the grass carp immunization injection, the survival rate has risen from about 60 percent to more than 92 percent, and the two-star grass carp species are healthy, neat and tidy, and have strong disease resistance.

2.Use the hill slope land to grow green fodder.

In order to reduce costs and increase efficiency, by planting ryegrass and Sudan grass on the slope of the gang, the herbivorous fish palatable green fodder was solved, and the yield of fresh grass per mu was 10,000 kilograms, which effectively reduced the use of pellet feed and reduced the commercial concentrate per mu. The main grass carp alone by throwing concentrate is absolutely not feasible, must be put a certain amount of palatable green feed every day to solve its natural eating habits to maintain growth, the role of grass is to pull the skeleton of grass carp in order to fertilize in the future, the second is to directly reduce the input to reduce the cost of production, so as to improve the economic benefits per unit area.

3.Adopt scientific water quality management measures.

Fill up new water regularly, at least three times a month, 20 to 750px each time, do not fill too deep at one time, exceeding the above water level may bring disadvantages to production. Turn on the aerator scientifically and reasonably, so that it can be turned on at noon on sunny days from 12 to 14 o'clock for two hours, from 2 o'clock to 10 o'clock in the morning on cloudy days, and around the clock on rainy days. Water quality improvers are used to improve water quality regularly, generally once every 10 to 15 days, and the varieties are EM bacteria and water refreshing.

Add some brown sugar alternately, improve the ecological environment of the pond water, and pay attention to four months to make the aquaculture water body adapt to the needs of the growth of the main grass carp.

4.Prevent fish diseases regularly.

Regular insecticide, grass carp is susceptible to parasitic fish diseases such as anchor head flea and Chinese flea, from the end of March began to use trichlorfon concentration in the whole pool to splash the insecticidal body, every 20 days and then use copper sulfate and ferrous compound concentration to kill insects, alternately use the above drugs so that the parasite can not infect the fish body. In the high temperature season, quicklime is used every half a month to use 10kg per mu, and the slurry is evenly sprinkled throughout the pond to increase the pH concentration, so that the pond water quality is in a weak alkaline to prevent disease.

Enlarge the size of seedlings, reasonable stocking density; From June to August, hot water fish will be produced, and large-sized fish will be produced at the end of the year, matching Haida high-grade extruded material and functional material; Pay attention to the increase of the yield of silver carp, and use algaein to increase the frequency of fertilizer and water.

When breeding grass carp, it is necessary to inspect its growth direction every day, and once it is found that the fish has a floating head, then it is necessary to turn on the aerator to increase oxygen.

Breeding grass carp should remember to carry out daily inspections to check the growth of grass carp, once the tendency of the fish floating head is found, it is necessary to immediately turn on the aerator, and it is recommended to turn on the aeration equipment uninterruptedly in the summer night when the temperature is high. In addition, it is necessary to pay attention to the replacement of water quality, if the water quality is too fertile, it is necessary to replace the new water in time, and regularly spray disinfectant powder to the pond, which can reduce the disease of the fish body.

There are many of them that live on the bottom, such as grass carp, if we all breed pelagic fish such as carp. In this way, we can moderately polyculture crucian carp, which is a demersal fish, and when the carp has uneaten or missed bait and sinks to the bottom of the pond, it provides abundant bait for the bottom fish. In this way, we can not only ensure that the carp have enough food, but also increase the income of the bottom fish with the same amount of bait.

Of course, the use rate of bait will increase, and it can also avoid the residual bait environment from polluting the water body and endangering the growth and development of fish.

In the case of feeding bait, we should pay attention to the specified timing and quantity, so that the fish can develop a better eating habit. When you feed the bait, you must not change the feeding address casually, otherwise it will cause some fish to not be able to eat at all. Then it is necessary to control the amount of feeding, and the amount of feeding should be adjusted within the effective range, to ensure that every fish can be full, and to avoid feeding too much.

Causing the quality of the residual bait will not only damage the water body, but also continue to have a serious impact on the growth and development of the fish if swallowed by mistake, so we must pay more attention.

One of the most common things that many fish farmers overlook is the amount of dissolved oxygen in the water, especially in the areas where the feed is fed. Nowadays, at least 70% of the dissolved oxygen is not enough, and if the dissolved oxygen is not enough, no matter how good the bait is, it will be in vain. If the amount of dissolved oxygen in the pond is less than 3 mg/L, the fish will stop eating.

It should be maintained at least above 5mg to allow the fish to eat normally. Therefore, we must ensure that the dissolved oxygen content of the water quality is above 5mg when breeding, and add aeration equipment in the breeding area to produce oxygen immediately.

When raising fish, we can use some of the leftover fish meat to feed, so that we can improve the utilization rate of bait, and can also be better farmed, which can increase production.

In the process of fish farming. Different bait should be released according to different fish species. In addition, it is necessary to feed on time and in the right amount, so that the bait will be used reasonably.

Depending on how you want to raise it, carp farming is actually very simple, you only need to have a water source with enough food, and of course ensure that it is clean and hygienic.

Carp are farmed mainly by unpolluted water, and are no different from other fish species.

The cultivation of carp is mainly based on fixed breeding, that is, there is a fish pond, and the income is achieved by breeding in the fish pond.

Feeding compound feed is an important way to reduce the cost of fish feed. However, fish with different diets and different stages of development need feed with different nutrients, so in order to make fish grow fast and feed costs low, the nutrients of the feed must meet the physiological needs of the fish. When making feed, it is necessary to choose the appropriate formula according to the nutritional needs of the main fish, which not only meets the nutritional needs of the main fish, but also does not waste feed.

The various raw materials are crushed and mixed to make a particle shape suitable for the main fish to eat, which is conducive to the absorption and utilization of nutrients by the fish, reduces the loss of feed, and improves the utilization rate.

<> belong to the free-range breed, and the main breeding should be highlighted. Fish farming with compound feed should not follow the traditional stocking model, that is, raising a variety of carnivorous fish in the same pond, but should be dominated by one carnivorous fish. In order to improve the water quality of the pond, make full use of the natural feed resources, and develop the potential of water production, other fish can be appropriately polycultured.

Generally speaking, the stocking proportion of staple high-quality fish such as grass carp, cockroach and crucian carp is larger, generally accounting for 80% of the total stocking, while filter-feeding fish such as silver carp and bighead carp can only account for 20%. Fish should be disinfected before stocking and then placed in ponds. Third, the stocking specifications should be neat.

Enough fish of the same size should be stocked at one time, and individual differences should not be too large, preferably no more than 20%.

High-quality fish grow fast and have a high rate of digestion and absorption of feed. In production, attention should be paid to the selection of fish with good appearance, intact body surface and health. In addition, in the stocking method, it is necessary to highlight the main fish and appropriately match other fish, so that you can choose the feed that is suitable for the nutritional needs of the main fish and improve the utilization rate of the feed.

or superphosphate 8 kg 10 kg. Chemical fertilizer can quickly increase the amount of planktonic nutrients in the pond, and has a good effect on silver carp and bighead carp.
