I put 3,000 catties of crayfish and shrimp seedlings, but I only received a few dozen catties, what

Inner Mongolia crayfish shrimp seedling breeding technology every morning to collect a dozen hundreds of pounds is also very easy, generally a pound of 50-200 tails on the good, the day to transport back a simple disinfection after putting into the pond, an acre of about 100 pounds, put in a part of the general death, often salvage dead shrimp, dead remember to replenish seedlings, whether you buy from the field or someone else to buy the pond, put back always to die a part, you buy from the local, **low, the cost of dying will not increase much, point: local seedlings, Don't listen to others what artificial reproduction is better, the second year you will breed in the pond yourself, this is the so-called artificial reproduction, the second year survival rate is high, adapt to the environment, the original pond grows, the seedlings will basically not die, so that the seedlings will save a sum, 5, feeding management this point There is a lot of information on the Internet, learn to follow it, in the middle of their own groping 6, about the yield is generally 300 catties, as high as 500-600 catties, the second year's output will be a little bit, because there is the original shrimp breeding, A pair of broodstock can breed hundreds of broodstock a year.

Those mean that the survival rate of the shrimp seedlings you put is too low, and the breeding methods should be learned more, and the shrimp seedlings should be paid more attention to in the growth process. If there is a large number of deaths, it should be dealt with in time, and the water quality, water temperature, and feeding should be paid attention to.

There must be a reason for that, one is the survival rate of shrimp seedlings, the other is that they were fished away, or you didn't catch it, you need to find the reason, what you said is too different!

Most of them died or most of them were stolen.

Well, there is a good raising. The survival rate is too low.

<> how many catties of adult shrimp can be raised from 100 catties of shrimp seedlings depends on the breeding technology, management methods, and breeding mode. If it is a shrimp-rice polyculture model, 100 kg of shrimp seedlings can raise about 240-360 kg of adult shrimp; If it is an intensive pond culture mode, 100 catties of shrimp seedlings can raise about 300-500 catties of adult shrimp.

1. How many catties of adult shrimp can be raised by 100 catties of shrimp seedlings

How many catties of adult shrimp can be raised depends on the breeding technology, management methods, and breeding mode.

2. If it is a shrimp-rice polyculture model, stocking about 100 kg of shrimp seedlings (5g tail), under the premise of proper management, its survival rate is about 60%, that is, only 60 kg of shrimp seedlings can survive (about 6000); The weight of the finished shrimp of each crayfish is about 20-30g, and the total output is about 240-360 catties.

3. If it is an intensive pond culture mode, stocking about 100 kg of shrimp seedlings (5g tail), under the premise of proper management, the survival rate of shrimp seedlings is 95%, and the survival rate from breeding to harvest is 80%, that is, there are only about 7,600 adult shrimp in the end. Because it is specialized in cultivating shrimp, the volume of shrimp produced is slightly larger than that of shrimp in the shrimp-rice polyculture mode, generally about 20-50g, and the final total output is about 532 catties based on an average value of 35g.

4. The above is the output under ideal conditions, under the influence of breeding technology, weather factors, etc., the output of lobster is generally a little less. In the intensive pond culture mode, about 300-350 catties of adult shrimp can be harvested.

2. When is it appropriate to stocking shrimp seedlings?

1. Crayfish are generally stocked in the morning or evening of the eye day in March and April.

2. Breeding technology.

1) Pond treatment: the breeding area is about 1-2 acres, and the water depth is deep. Before stocking, remove the weeds in the pond, and use 150-200kg of quicklime per mu of pond for disinfection, and then plant one-third of the pond area of aquatic plants (bitter grass, black algae, water hyacinth, water floating lotus) on the water surface of the pond, and set up bricks, stones and bamboo tubes and other hidden objects at the bottom of the pond for lobsters to inhabit and burrow.

2) Shrimp seedling stocking: 4000-7000 shrimp seedlings per mu (shrimp seedlings specifications, when the seedlings are released, the plastic bag containing the shrimp seedlings will be placed in the Gaoshi pond for 30 minutes and then opened, so that the shrimp seedlings can adapt to the water temperature in the pond.

3) Feeding: Feeding can be started about 30 minutes after stocking. Hand limb shrimp are fed 20-25% of body weight, medium shrimp are fed 15-20% of body weight, and large prawns are fed 10-15% of body weight, once in the morning and once in the evening.

When feeding, the amount of feeding at a fixed point and at night accounts for about 60-70% of the total amount of food.

4) Water quality: The dissolved oxygen of the water body should be above 4mg L, the transparency of the water body should be 30-40cm, and the pH value should be. The water is changed every 5-7 days in the high temperature season, and the water is changed every 15-20 days, and the water is 20-30% of the pool water each time.

Summary. In response to this question, my answer is: such a ** is unreasonable, because such a ** gap is too large, which is not conducive to the profit of the merchant.

The methods and practical steps to solve this problem are as follows:1First of all, merchants should set reasonable prices according to the market to ensure their own profits.

2.Secondly, merchants should make reasonable adjustments according to market demand to meet the needs of consumers. 3.

Finally, merchants should make reasonable adjustments according to their actual situation to ensure their own profits. The above is the solution and practice steps on how to solve the problem of crayfish buying 30 pounds and selling 98 pounds. When setting prices, merchants should set reasonable prices according to the market, market demand and their own actual situation to ensure their own profits.

The price of crayfish is 30 a catty, and it sells for 98 three catties, how about it.

In response to this question, my answer is: such a ** is unreasonable, because such a ** gap is too large, which is not conducive to the profit of the merchant. The methods and practices to solve this problem are as follows:

1.First of all, merchants should set reasonable prices according to the market to ensure their own profits. 2.

Secondly, businesses should prepare the sedan car according to market demand and make reasonable adjustments to meet the needs of consumers. 3.Finally, merchants should make reasonable adjustments according to their actual situation to ensure their own profits.

The above is the solution and practice steps on how to solve the problem of crayfish buying 30 pounds and selling 98 pounds. When setting prices, merchants should set reasonable prices according to the market, market demand and their own actual situation to ensure their own profits.

Excuse me, but please go into more detail?

In response to this late question, my answer is: This ** is very reasonable, because the purchase price of crayfish is 30 yuan a catty, and it is sold for 98 yuan and three catties, and the price per catty is yuan, which is slightly higher than the purchase price, but it is also within a reasonable range. In addition, the ** of crayfish is also affected by the supply and demand of the market, if the market supply and demand are unbalanced, the ** of crayfish will have **, so that higher profits can be obtained.

In addition, the ** of crayfish is also affected by seasonal factors, if it is the peak season of crayfish, ** will be relatively high, but it is a bridge, if it is the off-season, ** will be relatively low. In short, the ** of crayfish is affected by a variety of factors, and the ** of 98 yuan and three catties is combusting, and you can get a certain profit.

Crayfish farming market prospects**The report mentions that lobster farming is very profitable. About 120 catties of shrimp per mu, each ring rolling breeding and feeding method, the annual yield per mu can reach about 3000 catties, one-time shrimp seeds, no longer buy seeds within 3-5 years, and the descendants are not degraded, do not mutate, and the yield per mu remains unchanged for a long time.

Now based on the estimated budget of 120 catties of shrimp per mu, the number of female shrimp per mu is as follows

The amount of casting, sheltering, trembling, and amplification is 120 catties per mu, 20 catties = 2400 mu.

1140 mu 200 times 2 times a year = 456000 mu per year.

The survival and failure rate of seed shrimp from spawning to growing into juvenile shrimp is 8% to 30%, and the total number of adult shrimp produced per year is calculated according to the minimum 8%.

456,000 8% = 36,480 mu per year.

Spawning 2-3 months can be marketed, each adult shrimp weight to 50 grams (about 10 catties), the total annual yield per mu is: 36480 and 12 catties = 3040 catties per year.

This question is very simple for farmers who specialize in crayfish farming. Crayfish farmers breed crayfish will argue that there are two options: the first option: about 40 catties of shrimp per mu of shrimp ponds, and the second option

80 100 pounds of shrimp seedlings per mu of shrimp ponds From the above situation, a pound of shrimp can leave the state vacancy of 2 pounds of shrimp seedlings, this is not my nonsense, this is my experience summed up by many years of shrimp farming! Hope mine is helpful to you! I am a small rural area, focusing on answering the problem of crayfish farming in the spring.

Thank you for your attention!

Summary. Dear, crayfish farming market prospects**The report mentions that lobster farming profits are very considerable. About 120 catties of shrimp are put into each mu, and the annual yield per mu can reach about 3,000 catties per mu.

Crayfish seedlings are 10,000 catties of shrimp seedlings, how many shrimps can be produced at most?

Dear, crayfish farming market prospects** report Qinghe Tihui closed, lobster farming profits are very pre-cracked and considerable. About 120 catties of shrimp are put into each mu, and the annual yield per mu can reach about 3,000 catties per mu.

Can chicken manure feed lobsters?

Dear, yes. First of all, the feed of crayfish is divided into animal and plant feed, and the animal feed is trash fish, miscellaneous meat, offal, etc. Plant-based feeds are wheat, aquatic weeds, rapeseed cakes, etc.

In fact, chicken manure can also be used as crayfish food, but it can be fed directly without selling pants, because chicken manure contains harmful substances such as roundworm eggs. Direct feeding will pollute the water quality and cause disease at the same time, but you can use fermented chicken manure as feed to feed shrimp in the draft, and the effect is very good.

Summary. Crayfish fry with a water quality of 3000 kg may breed about 300-900 kg of crayfish.

Crayfish fry with a water quality of 3000 kg may breed about 300-900 kg of crayfish.

Fellow, I really didn't understand, I can be more specific.

The reproduction of crayfish is affected by a variety of factors, such as breeding environment, water quality, feed, breeding density, etc. Therefore, it is impossible to accurately determine how much 3000 catties of crayfish can reproduce. Generally speaking, the reproduction rate of crayfish is between 10%-30%, which means that 3000 catties of crayfish fry may breed about 300-900 catties of crayfish.

However, the specific amount of reproduction needs to be assessed according to the actual situation.

According to the size, there are about 39-60 crayfish in general, if it is a crayfish with a larger head, it is estimated that there are about 13 crayfish, and if it is a crayfish with a smaller head, it is estimated that there are about 20 crayfish with a catty. Crayfish is a freshwater economic shrimp that is popular because of its delicious meat. Because of its chaotic and envious nature, fast growth rate and strong adaptability, it has formed an absolute competitive advantage in the local ecological environment.

Stocking of shrimp fingerlings of crayfish:

1. Thoroughly clean the pond: 20-30 days before the shrimp destroyed tung seedlings are stocked, the pond water needs to be drained, too much silt needs to be cleaned up, the pond dam should be repaired, and 75 kg of bleaching powder should be used per mu to thoroughly disinfect the pond.

2. Apply sufficient base fertilizer: apply 500-600 kg of livestock and poultry manure per mu to cultivate insects and cladopera, and provide bait for shrimp seedlings.

3. To plant good aquatic plants: some aquatic plants such as algae are planted in the breeding pond, and the planting area should occupy the shrimp pond area 2 3. At the same time, erect mesh pieces or place some bamboo tubes, plastic buckets, etc., to provide a place for lobsters to rest, molt and hide.

It is recommended to soak lobster in water for 2-3 hours after cooking lobster at home, the head of lobster is easy to absorb heavy metals and bacteria, so it is recommended to remove the head when eating, then brush it clean, and cook it at high temperature before eating, because lobster has high protein content, and after the protein rots, it will be detrimental to human health, so after the lobster is done, it is recommended to eat it all at once, and it is not advisable to eat too much lobster, because excessive protein intake is also easy to cause indigestion.
