Different models of farming methods are different, what is the Australian lobster farming model?

Australian lobster is now very expensive, farming, the economic benefits of Australian lobster are considerable, but the use of advanced science and technology when farming, so as to obtain benefits.

These animals are breeding in some reservoirs, it is free-range, the water quality is alkaline, the temperature of the water is about 25 degrees, there is a lot of oxygen in the water, there are some organisms, generally in April and June, the seedlings are released, so that the breeding model can have a better harvest.

The Australian lobster farming model is mainly divided into several sections, namely shrimp pond selection and capital construction, shrimp pond sterilization and disinfection, as well as the promotion of seedlings, feed feeding, daily management methods during breeding, etc.

The risk is still relatively large, because this lobster in the process of breeding, the requirements for the environment and feed are relatively high, and the survival rate is not particularly high.

The risk is still very large, and many people dare not raise lobsters because the risk of lobsters is really high. Therefore, there are fewer people.

The risk is very high, because this Australian lobster is suitable for survival in the European region, and it is still quite difficult to breed in the Chinese region.

Farming Australian lobsters is very risky because our waters in China are not very suitable for them to survive.

There are a lot to pay attention to in Australian lobster farming, what are the Australian lobster farming techniques? Australian lobster has a good metabolism and fast growth, so the water quality of the shrimp pond must be kept clean, it is best to add 15 to 20 cm of water a week, so that the water quality of the shrimp pond has enough dissolved oxygen, and the transparency of the shrimp pond water is best controlled at about 35cm. There are many natural predators of Australian lobster, such as rats, frogs, water birds, etc.

Breeders have to pay attention to rodent infestation, exterminate rats in time, and remove frogs in the pond. You can take some precautions, such as putting a fence 30-40 cm around the shrimp pond to prevent frogs and water snakes from invading.

Feed feeding: feed feeding adhere to fixed-point, timed, qualitative, quantitative feeding, in the early stage of feeding to small trash fish, foot meat and artificial compound feed; In the middle and late stages, all crushed snails, mussels and an appropriate amount of plant feed were fed.

Australian freshwater lobsters (crayfish) do not need to be baited; Natural reproduction is at its peak from May to October every year, and it can reproduce automatically after introduction. Therefore, in the process of industrial farming, it is necessary to strictly prevent escape, especially not to allow it to enter the original ecological reservoir that is difficult to reach. Prevention and control can be devastating for native species.

One thing I know is about the cultivation of shrimp seedlings, because shrimp seedlings will directly determine the final result of Australian lobsters, which needs to be strictly controlled, otherwise it is very likely that you will lose all your money.

The suitable water temperature for lobster growth is 24 -30, when the temperature is lower than 20 or higher than 32, the growth rate decreases, and the survival rate of larvae is very low when the water temperature is below 15. The temperature difference between day and night in feeding waters can not be too large, the temperature difference between day and night of young shrimp should not exceed if you use soil pond breeding, if you have economic conditions, you can set up a dragon frame in the middle of the pond, and the pond side is separated by one meter on all sides, and the water pipe is left 20 centimeters, and then the wire rope is paved with adhesive tape, and the cost of one mu is about 3,000 yuan.

Australian freshwater lobsters have two ways to overwinter in the country. The first is the wintering method of the outer pond. It is necessary to add membrane insulation to cover the outer pond, and the water depth is maintained at about 2 meters, which can be used in Guangdong, Guangxi, Fujian, and Hainan.

Most of the rest of the provinces in China use the second way, Australian freshwater lobsters are very easy to die when the water temperature is lower than 12, and the insulation mode of "cement pool + greenhouse" can survive the cold winter smoothly.

Lobsters are more afraid of colder environments, and if the temperature drops, the impact on them is huge, and there are often more things to do during the winter. In recent years, its demand is indeed relatively high, it is a very popular aquatic product, and now there are more and more farmers, and they can be stocked outdoors. When it rains for a long time, the soil is full of water for a long time, which will cause the roots to breathe hard and lack oxygen.

And soak the roots of the tree, you should move the tree to a place and strengthen the water temperature control. Australian freshwater lobsters are very easy to die when the water temperature is lower than 12, and the insulation mode of "cement pool + greenhouse" can survive the cold winter smoothly.

If you use the soil pond to breed, if you have economic conditions, you can set up a dragon frame in the middle of the pond, the pond side is spaced on all sides of one meter to play a meter of water pipe to leave 20 cm, and then pull the wire rope to lay adhesive paper, the cost of one mu is about 3,000 yuan. If you breed in the south, the greenhouse can survive the winter, if it is the north, it is best to cement pool + greenhouse If you count nine days, it is best to add some fuel at night, you can start to build a windshield or cold-proof shed in the northwest corner of the breeding pool, the suitable water temperature for embryonic development is 22 -32, if you keep 28 -30, the incubation time can be greatly shortened to a certain temperature!

It is necessary to pay attention to the environment of lobster farming, the temperature can not be too high and not too low, and it is necessary to choose nutritious feed to feed lobsters, so that lobsters will grow plump, we must pay attention to these points.

Waterproof damage to insects and larvae. Therefore, it is necessary to pay attention to the disinfection and cleaning of the pond before feeding, take certain preventive measures and strengthen the management of feeding. Red crayfish is very susceptible to crayfish diseases, in addition to susceptible to a fungus caused by a shrimp disease called "crayfish plague", as long as the water temperature of shrimp seedlings stocking and fishing is above 21, the occurrence of "crayfish plague" disease can be avoided.

In addition, in the cultivation can be regularly exchanged every 10d1 use: quicklime 20mg l; copper sulphate plus ferrous sulphate; furazolidone 1 2 mg l; Rhubarb 4 5mg l is sprinkled throughout the pool to prevent disease.

Shrimp pond construction. Freshwater lobsters like a water environment with fresh water quality and abundant dissolved oxygen, so it is necessary to choose a place with ventilation and sunshine, quiet environment, sufficient water sources, no pollution sources, and convenient drainage and irrigation.

Shrimp fry stocking. Shrimp seedlings should be stocked in March and May, when the water temperature is kept above 18 for a few days, the seedlings can be planted. Choose a sunny day in the morning or late in the evening.

Bait feeding. The shrimp has a mixed diet, and can eat fresh and tender grass roots, humus, aquatic plankton to small trash fish, snails, soybeans, and also likes to eat shrimp compound feed.

Shrimp pond management. The shrimp pond needs to be managed by a special person, and it is necessary to inspect it frequently, patrol the pond frequently, and replenish the number of aquatic plants at the bottom of the pond in a timely manner.

Daily management during the breeding period: in the daily management should be done diligent inspection, frequent patrol of the pond, timely removal of moss in the pond, keep the water quality of the shrimp pond fresh, there is enough dissolved oxygen, the transparency of the pool water is about 35 cm, often check whether the filter screen of the inlet and drain is damaged, to prevent shrimp from escaping and wild trash fish and other predators to enter, when encountering thunderstorms and sultry days, even cloudy days and other bad weather, to reduce or stop feeding, when the weather is too hot and too cold, should be appropriately deepened pool water to stabilize the water temperature, at the same time, It is also necessary to frequently observe the feeding and activity growth and shelling of freshwater lobsters.

Summary. Hello dear, Australian lobster (scientific name: Australian spiny lobster), also known as Australian freshwater lobster, Australian red crayfish [1], is a genus of arthropod phylum rock lobster, distributed in southern Australia, Tasmania Island, Australia.

Australian lobsters have a mixed diet, fast growth and high yield; Adaptable and able to tolerate harsh weather environments. Its body color is inlaid brownish-green, the cephalothorax and abdomen are evenly connected, and it is covered with a hard shell; There are 5 pairs of thorax and feet, and the first pair is particularly developed into a powerful chela.

The difference between Australian lobster and prawn farming.

Hello dear, Australian lobster (scientific name: Australian spiny lobster), also known as Australian freshwater lobster, Australian red crayfish [1], is a genus of arthropod phylum rock lobster, distributed in southern Australia, Tasmania Island, Australia. Australian lobsters have a mixed diet, fast growth and high yield; Strong adaptability, able to endure bad weather environment.

Its body color is inlaid brownish-green, cephalothorax and abdomen evenly connected, and covered with a hard shell; There are 5 pairs of thorax and feet, and the first pair is particularly developed into a powerful chela.

Shrimp is the common name for small aquatic crustaceans with exoskeletons and ten-legged (i.e., members of the order Hook-footed Crabs), some of which can be eaten as megans. [1] In countries such as the United Kingdom, Ireland, and the Commonwealth, shrimp refers to large swimming crustaceans or shrimps, especially those that are commercially significant in fisheries. Shrimp that fall into this category usually belong to the order Zophrenae.

In North America, the term mill is not commonly used and is usually used for freshwater shrimp. The terms shrimp and prawn themselves lack scientific basis. Over the years, the usage of shrimp and prawn has changed, and now the two words are almost interchangeable.

Lobsters are more afraid of cold environments, and if the temperature drops, the impact on them is huge, and winters tend to be busy. In recent years, it is indeed in high demand, it is a very popular aquatic product, and now there are more and more farmers, but there are also many risks. There are still many problems in aquaculture, how to do better must pay attention to small details, now the temperature drop is indeed outrageous, many aquaculture people do not know how to solve these problems.

First of all, it can be appropriately carried out for a period of intensive cultivation before winter.

Generally speaking, when the water temperature drops to 12 degrees Celsius, it is necessary to start paying attention to increasing the amount of feed. We should let its fat accumulate little by little and store a certain capacity, so that the final growth effect will be better. There will be no more problems in the winter, and some pellet lobster feed is generally chosen when feeding.

Longer feeding times can still be of great help. Some friends may feel that it does not eat much and may choose to stop feeding. In fact, this method is not very good, and it will only stop when the water temperature drops to an octave.

When the temperature is below 20 or above 32, the growth rate decreases. When the temperature is below 15, the survival rate of the larvae is low. The temperature difference between day and night in the feeding waters should not be too large.

The temperature difference between larvae and juvenile shrimp should not exceed 3, and the temperature difference between day and night of adult shrimp should not exceed 5, otherwise it will cause great losses. In the Pearl River Delta and the coastal areas of South China, they can generally overwinter naturally, and in order to prevent large cold waves, the overwintering adult shrimp can be placed in deep ponds, and wind walls or cold shelters can be built in the northwest corner of the ponds. The optimal temperature for embryonic development is 22 -32 , and if the temperature is kept at 28 -30, the incubation time can be greatly reduced.

The pH value of lobsters is suitable for pH range, but the pH value during the incubation period is about and the amount of dissolved oxygen exceeds 3 mg l. But it's so alive that Australian freshwater lobsters have two ways to winter at home.

One is the way of wintering in the outer pond. It needs to be covered with film insulation, with a water depth of about 2 meters, which can be used in Guangdong, Guangxi, Fujian and Hainan. Most of the other provinces in China adopt the second way, that is, thermal insulation greenhouses, cement ponds for wintering.

Wintering in Waitang is more economical, but because Australian freshwater lobsters are a tropical product, winter temperatures in most parts of China are not up to the mark. Greenhouse winter, mostly boiler heating heating, but the cost is a bit high. The water temperature of the pond is kept at about 20 degrees Celsius, and the greenhouse is kept at about 25 degrees, and the dissolved oxygen is sufficient to safely overwinter.

Keeping the water clear, adding about 15 cm of water every week, paying attention to controlling the transparency of the water, paying attention to rodent infestation, putting purse seine nets around the shrimp pond, etc., only by paying attention to these skills can you breed lobsters well.

Australian lobster farming techniques: pond selection, aquatic weed planting, stocking density, bait feeding, water quality management, as follows:

1. Pond selection.

It is best to choose a pond in a place with sufficient water, open ground, and slightly sloping terrain. The area of the pond can be large or small, the water depth is appropriate, the water quality is required to be fresh and pollution-free, the dissolved oxygen in the water is more than 4mg L, the pH value, and it is equipped with all kinds of drainage and irrigation and aeration equipment.

2. Aquatic weed planting.

Aquatic plants are planted along about 20%-50% of the shallow water around the pond, and generally choose to plant Elephyllum nigra and Elophylla. Plants in shallow water and add water gradually after the aquatic plants are gradually surviving. In addition, a small amount of water peanut grass balls and water hyacinth can be transplanted on the surface of the pond.

3. Stocking density.

Shrimp seedling cultivation pond stocking density does not exceed 1000 m2 is appropriate, appropriate thinning and timely feeding is conducive to improving the survival rate, a shout of no general cultivation survival rate can reach 50%-70%, pay attention to do a good job of pond disinfection before releasing seedlings.

4. Bait feeding.

In the early stage, small trash fish, leg meat and artificial compound feed were the mainstay; In the middle and late stages, all the crushed snails, mussels and suitable sails are fed with macro-based plant feed. Bait feeding should follow the principle of timing, fixed point and quantitative, and generally feed once a day in the morning and evening.

5. Water quality management.

Regularly monitor water quality, apply fertilizer on time, replenish beneficial bacteria frequently, and use calcium, magnesium, phosphorus fertilizer or sodium humate fertilizer. In addition, add 10-15cm of water every 10-15d to ensure the transparency of the water body, and sprinkle 3-5mg l of quicklime on rainy days. If a large number of shrimp seedlings molt, it is necessary to pour activated calcium in time.
