Hello everyone! I am Rao Xiaokun, for a long time did not update the article, these two days began to enter the plum, the rainy day came, now there is time to talk to you about a period of time ago many people came to ask a question about the situation of the pond mouth mouth, in the crab breeding process really there are so many water traps? What is Aquamania? Could it be that the water slugs will appear out of thin air? Is there really any miracle medicine that specifically prevents and treats water sickness?
At present, the mainstream definition of water deflector is as follows:
Water crab liver pancreatic necrosis is a common name for river crab liver and pancreatic necrosis, has become one of the main diseases in the late stage of breeding, its etiology is more complex, basically can cause river crab liver pancreatic lesions factors can induce the production of "water crab", the mortality rate is higher, even if not dead will greatly reduce the specifications of commercial crabs, no fat and no paste is difficult to list.
The main symptoms of the water dehydration:
Lying still under the aquatic weeds for a long time, the amount of food intake has decreased sharply, and it is difficult to molt, molt, and even the molting carapace is difficult to harden. Liver and pancreas are whitish, erosion is water-soluble, abdominal cavity is a lot of water, the gill surface is intact, microscopic examination found that the gill filament hairs are seriously damaged, occasionally mixed with a small number of bubbles (bubble disease), muscle atrophy (less water-filled flesh in the appendages), the abdomen is white and partially transparent, and the intestines are basically inedible or full of yellow substances (liver and pancreas excretion).
Many times, when we find that the tangkou appears to eat compared to other people's pond mouth at the same time to eat less, we will pay attention to the beginning of the ground cage to catch crabs up to see, this point in time only to find that most of the crabs in the pond mouth are empty intestines, legs are soft (different from the tangkou crabs that have just shed shells), crab vitality is not too good, began to be anxious, began to according to the major expert pharmacies to start the whole pond disinfection to change the bottom detoxification to a set, and then began to mix what liver protection and bile protection, what three yellow and five yellow dew , food promotion appetizer, multi-dimensional minerals and so on, however, what about the results of the back? People who have experienced it know that it doesn't seem to have much effect!
Now that we have reached this point in time, we should think hard about what the real problem is. Is it the cause of the crab fry? Or is there a leak in the pond mouth management after the crab seedlings go down to the pond? Or are there problems on both sides?
We need to calm down and sort it out well, learn to use the elimination method to consider the problem, first of all, is it because of the crab fry? This is a possible factor, because crab fry occupies a very important position in the whole process of crab breeding, so this is also what we have been stressing to you before the selection of crab fry needs to take some effort, the specific how to choose a good crab fry can see the following related article links:
What do you rely on to choose high-quality crab seedlings? The truth is not hidden, in the next leaning on the Meng!
We are often easy to ignore some seemingly ordinary details, we all know that after the crab seedlings began to cool down years ago, the basic crab seedling pond began to stop feeding, until most of the crab seedling ponds began to produce crab seedlings, this time is about a month! It also means that the crab seedlings you put in the mouth of the spring pond have not eaten for about a month before the seedlings are released, until the spring you put the crab seedlings into the pond, this point in time is interesting, you think about it carefully, you will find that the crab seedlings you take will have three situations:
The first possibility: crab seedlings in the crab seedling pond have a good physique, after the beginning of the spring feeding, there is basically no abnormality, are normal feeding situation;
The second possibility: crab seedlings in the crab pond have better physique, after the beginning of the spring feeding, especially when the spring feeding fish, there is too much food, overeating, this situation is prone to acute enteritis;
The third possibility: crab seedlings in the crab seedling pond due to various reasons caused by poor health, coupled with a month of hunger, appear in the spring feeding time, there is basically not much food anorexia!
The above three possibilities, I talk about many people clearly, will feel that it is indeed such a thing, but I have never thought about it like this, since you know that there are these three possibilities, you need to learn how to avoid such a situation, so that you can understand why choosing a good crab seedling is particularly important, so in addition to the choice of good crab seedlings in the seedlings, what else can we do? How to avoid overeating crabs? How to save an anorexic crab back? Leave that to your own thoughts!
Then the problem comes again, surely some people will say, the crab seedlings placed in my pond mouth are all red-billed, the feeding line is very full, in order to still appear so many watery people ah?
You will think like this to show that you are now beginning to learn to think about the problem, the above focus is on the crab seedlings on the emergence of water deflection factors, and then is the pond mouth management above, will lead to crabs appear in the water deflection factors, what dissolved oxygen is insufficient, what toxin residue, what weather changes, what bacterial infection, water weeds are too dense, etc. These factors may exist, but, the normal management of the pond mouth, regularly change the bottom disinfection and detoxification, but also add that the temperature is generally low in the early stage of breeding, the toxin residue, the dissolved oxygen is insufficient, The possibility of bacterial infection is very small, and the most likely one is the one that everyone is most likely to ignore - the water weeds are too dense, resulting in lazy crabs!
The breeding mode around Xinghua is mainly Ring Gou Il algae, and when planting Elae algae, it likes to plant large aquatic weeds, which has certain advantages when the water grass grows in the early stage, but as the water weed grows bigger and bigger, especially after the water level rises, the Ring Gou Elagae grows water, in this case, many crabs are hiding in this large Elagae, hiding in the grass during the day, climbing the grass at night!
You must think this is very normal, always feel that they will definitely come down to the feeding area to eat, but the actual situation is different from what you think, some crab seedlings have been trapped in this large Ilean algae, and have always felt that their owners have not been fed after the crab seedlings went down to the pond, you are interested in going to the Elastane to catch a few of these crabs, and then go to the beach to catch a few crabs, make a comparison you will find that the same crab pond, the two locations are different, the crabs are also very different, The crab body surface that has been in elafella for a long time looks more ugly, the physique is relatively worse, and the feeding line is naturally worse!
So in the above situation, you should know how you need to deal with it, right?
In fact, there is another factor is the management of feeding on the above serious mistakes, especially when feeding ice fish, a little careless may regret it, due to the limited length of the article, here is not in detail, this I will remind everyone in our crab boss's WeChat group, if you want to know more about this, you can scan the code at the end of the article to add my personal WeChat, specific analysis, and then carry out the corresponding follow-up processing!
For a crab, in fact, not only crabs, all living things are the same, for various reasons, resulting in enteritis, after a long time of not eating, but the individual is still alive and not dead, in this case, the individual is active every day, where does the energy required for activity come from? Definitely consume the individual muscle tissue to provide this part of the energy, after a long time, you will find that the biological individual is skinny, the specific crab above is reflected in the legs are weak, there is no muscle in it is basically water, when the entire muscle tissue is exhausted, and finally consume their own liver, this is what you see as "water deflection"!
Having said all this, you must be wondering how to operate in such a situation at the mouth of Fadang Tangkou?
I'm just going to tell you one story, and it could be said to be an accident! If you eat something bad at home, resulting in stomach discomfort, at this time the family gives you stewed duck soup, old hen soup, rib soup for you to drink, do you think that in this state you drink these nutrient-rich soups can cure your stomach discomfort? Do you have the appetite to drink these soups?
Can you think about what you would do when your stomach is not feeling well? Then think about what is the really effective way to solve this kind of situation?
After that, you then compare this situation to your crab pond, when you find that the crab pond eats a decline, there are more crabs in the jejunum, this time you give it some so-called high-tech nutrition products every day, what liver protection and bile protection, what stomach digestion, etc., the specific nutrition We do not talk about for the time being, when the crab diarrhea, have you considered the feelings of your crabs? Will this really work?
This year I have dealt with three such cases of the pond mouth, analyzed the reasons, and then targeted adjustments, basically achieved very good results, the original 40 acres of feeding 20 pounds of material can not eat, the proportion of jejunum is particularly large, now feed plus corn 120 pounds can basically eat, the original peak period of death of two or three hundred per day, analysis out of the cause of timely adjustment, now every day to damage crabs on individual damage crabs, only the right medicine is possible to stop the crabs of unknown causes of death, the cause can not be found, Blindly using drugs, in the end, it is basically a waste of time, because the reality of the situation really does not exist any magic medicine!
When you have sorted out the above logic, by the way, you can also consider, what kind of mixture is what kind of medicine you need? How many medicines are the so-called health care products, usually can be mixed or not mixed, the real pond mouth problem mixed with the type of white mix, until you want to understand you will know the trade-off!
You should have a certain understanding of the water stammers by now! Do you still think that the water is magical? Suddenly there is a water deflation at the mouth of the pond? Out of thin air?
Anything that has an effect must have a cause!
Raising crabs where there are so many watery deflations, some are just that you did not cure the enteritis in time!
When you have diarrhea, and do not open your mouth to eat anything, your family at this time to prepare a bunch of nutritional supplements, but you do not eat at all, do you have diarrhea can be good? Raising crabs has really fallen to the point where the pond is full of water sacks, and no amount of magic medicine you use to cure the sycamores will have no effect!
Well, I personally like to communicate with you the logic of thinking, according to the logic of scientific thinking to deal with problems, if the logic is not clear, then it will definitely be more difficult to do things.
This is an impetuous society, even far away from the city of river crab farming is difficult to escape the current impetuous state, many people have problems, impatient, never choose to calm down to think about the reasons for the problem, and choose to go around to trial and error, naturally to pay the price of time and money!
