Some loaches were put into the breeding of crayfish, why did not a single loach disappear later?

Now the wild loaches in rural areas are becoming less and less, and even in many places have become extinct, many rural farming uncles have said that in the past, they could often step on the loaches on their feet in the fields, but now they can not catch a loach when they turn the whole field upside down. I believe that this situation is the same in many places now, and I really can't blame anyone else, but we can only blame ourselves for the overuse of herbicides in order to save trouble. The herbicide is very toxic, not only can it directly kill the loach, but even the eggs of the loach can be poisoned.

So now that the eels and loaches are gone, the culprit is ultimately due to the heavy use of herbicides.

In recent years, more and more people are cultivating loaches, and there are more and more people engaged in crayfish farming. If you don't have experience, you may feel that there should be no problems with the two polyculture, and you can grow together without incident. But the truth is far from being as simple as it seems.

As the subject said, when breeding crayfish, a lot of loaches were put in the shrimp pond, but in the end, when the pond was dry, there was not a single loach, which I think should have been expected at the beginning. As a highly vigorous organism and an omnivorous animal, crayfish have a very fast reproductive ability. If the crayfish and loaches are farmed together, then the number of crayfish must exceed the loaches, and the two must compete for living space, and the crayfish have a fierce temperament, if the food is not put in time, it is very likely to catch the loaches to eat.

Although the loach is also good to drill holes, but compared with the crayfish is simply a small thing, even if the loach hides deeper, as long as the breeding density of the crayfish reaches a certain level, then there is no room for loaches to survive. Generally, in the end, the loaches become the food of the crayfish, and half of the loaches live on the soil, which is easy to be preyed upon by the crayfish.

Therefore, the phenomenon of the subject is not thought to be that the loach is eaten by the farmed crayfish. Therefore, when farming crayfish, it is best not to mix loaches, because it is difficult for the two to coexist peacefully. And the growth rate of crayfish is too fast, even if the loaches are raised now, and then the crayfish seedlings are put in, the growth rate of your crayfish will far exceed that of the loach, and eventually the loach will become the food of the crayfish.

So it is recommended not to breed the two together, what do you think?

Because they are all eaten by crayfish, although crayfish eat grass, they still like to eat meat, and they like loaches even more, so they should not be raised together.

"They will eat small water worms, crayfish will not eat in general, but crayfish will eat loaches. ”

The polyculture of loaches and crayfish depends on the breeding method, and the extensive culture type is definitely not good, and the loaches will be eaten by adult shrimp; The intensive culture type is feasible, and the crayfish will not catch loaches for food after being domesticated by artificial regular feeding bait, and they use each other to grow together and complement each other.

The extensive culture method is that the artificial bait is little or irregular, and most of the food depends on the crayfish to find aquatic weeds, algae, and weak aquatic animals for food. Adult loaches are weaker than adult crayfish, and they can't compete with crayfish, but they become the belly of crayfish. Therefore, the extensive breeding method, crayfish are not artificially fed, and live in a state of hunger for a long time, and must look for food everywhere to satisfy hunger, and the more loaches are raised, the less they are raised, especially the young loaches are getting fewer and fewer.

Therefore, in this way of farming, loaches and crayfish should be cultured separately.

Intensive farming methods are the opposite of extensive farming methods. Crayfish rely on their own to find less opportunities for food, mainly artificial timing and fixed quality and quantitative feeding of bait, crayfish in the full stomach, rarely look around for food, waiting for hunger, and start a new round of feeding bait. The long-term domestication process repeats itself, and crayfish have no sexual interest in catching loaches for food.

Therefore, this carefully fed and domesticated crayfish can grow together with the loach for a long time and live in peace with each other. Moreover, the loach can also deal with the bait and excrement left over from the daily eating of crayfish, which avoids the deterioration of water quality, greatly purifies the water quality, and reduces the harm of many harmful bacteria and toxic substances of crayfish. In this farming method, crayfish and loaches coexist, use each other, and complement each other.

In short, in the extensive farming method, crayfish and loaches cannot be co-cultured, and loaches will be harmed, and the number is getting smaller and smaller; In the extensive farming method, crayfish and loaches can be co-cultured, and loaches and crayfish use each other to complement each other.

Loaches can't eat crayfish.

Loaches generally come out at night to live, will come out to prey on some planktonic organisms, aquatic insects, crustaceans, aquatic higher plant detritus and algae and other things, sometimes can also ingest humus or mud residue from the bottom of the water, artificial breeding time, can be fed some fly maggots, fish meal, pig blood meal, silkworm chrysalis powder, rice bran, wheat bran, vegetable cakes and so on as bait.

Loaches don't eat crayfish, crayfish eat pears are about the same, when you kill loaches, the loaches can't bite you, he can't gnaw can't move, unless the crayfish is dead, Xiu may go to the shell of the west crayfish, that is, eat the meat in it, or the crayfish has a wound, that is, it is injured, this toothless fish, may go to suck.

Loaches generally come out at night to live, will come out to prey on some planktonic organisms, aquatic insects, crustaceans, aquatic higher plant detritus and algae and other things, sometimes can also ingest humus or mud residue from the bottom of the water, artificial breeding time, can be fed some fly maggots, fish meal, pig blood meal, silkworm chrysalis powder, rice bran, wheat bran, vegetable cakes and so on as bait.

"They will eat small water worms, crayfish will not eat in general, but crayfish will eat loaches.

Loaches will compete for the bait of crayfish, eat crayfish and shrimp seedlings, the amount of activity is large, affecting the water environment, especially for the shrimp rice field mainly relying on crayfish and shrimp seedlings to make a profit, cleaning miscellaneous is particularly important, generally in the field or release water these low water level, the use of lime or pond products to remove. After the removal, there will be much less reproduction in the second year.

Leave it alone. As long as the shrimp fry are big enough, the loach can't eat the crayfish. Nowadays, crayfish are all cage cultured, and loaches can't eat if they want to. Moreover, it can solve the pollution of the remaining feed to the water body, make the water body cleaner, and benefit the health of crayfish.

After the crayfish grow up, they eat loaches, after May, the crayfish in the shrimp field gradually grow up, and when you fish in the cage at this time, you will find that most of the loaches that enter the cage are caught by the crayfish, and some even eat only one thorn. Every year, when the wild trash fish is cleaned up, these trash fish loaches will be removed, but just like crucian carp, there will still be these trash fish in the shrimp field next year, but in smaller quantities.

Nowadays, many areas are practicing the co-culture model of crayfish and loach, but this model is very difficult to implement in practice. The key is that there are many farmers who don't even know their living habits, let alone their mixed breeding, mainly because they have different growth and feeding cycles. But there are very few things that can really be done, what if there are a lot of loaches in the crayfish?

Normally, if there are many loaches in the rice field, it will be harmful to the growth of crayfish. First of all, the pond water is very turbid, and a loach will compete with crayfish for survival resources, whether it is living space or food survival resources, which is a kind of competition. Crayfish are weaker in molting, and loaches can harm their molting.

In this case, we must first maintain the observation to confirm whether there are a lot of loaches and miscellaneous fish, if it is a small number of loaches, it doesn't matter, usually use the equipment to catch loaches to catch some that can be taken home to eat or can be sold in the market, so as to increase some income. If it is too much, then you need to use tea cakes to disinfect and sterilize, and then add some bottom-changing drugs together will be faster, because the loach itself lives in the silt of the substrate, so it will be better with some bottom-changing drugs.

For loaches, they should be red blood cell organisms with a back, and they can choose to use tea cakes to kill red blood cells, and they can also choose to clear ponds (pesticides have been banned by the state), which are usually rotenone products. Of course, killing loaches will cause some damage to crayfish juveniles, or it is best to be cautious in the case of killing.

Loaches compete for the bait of crayfish, eat crayfish and shrimp seedlings, the amount of activity is large, and the water quality and environment are endangered, especially for the shrimp and rice fields mainly rely on crayfish and shrimp seedlings to make money. After elimination, there will be much less reproduction the following year.

These loaches can be scooped up, and the loaches can be scooped up with nets.

Grab the loaches and eat them yourself, or sell them。In addition to competing with crayfish for oxygen, loaches have no effect on crayfish, and when crayfish grow up, they will also eat loaches.

If there are a lot of loaches in the field, you can go and drain all the water in it, and then clean up all the loaches.

You can choose loach, lobster polyculture mode, this breeding mode is designed by using the different breeding cycles of the growth of the two, can make full use of water space resources and bait resources, do the first half of the lobster culture, the second half of the loach culture, with the advantages of short breeding cycle, less investment, and quick income.

The lobster culture cycle starts from the stocking of shrimp fingerlings in September of the current year and ends in July of the following year. Lobsters enter the burrowing and breeding period from the lower pond, and basically do not move outside the hole, and this is a good time for loaches to grow and develop. When entering the peak growth season of lobsters and the peak fishing season in March and June, loaches are in a state of reproduction and can be cultivated in another pond.

Large-sized loach species can also be rotated in lobster ponds, so that loaches can reach market size within two or three months.

It is not recommended to breed together.

Because loaches are more active in the growth and reproduction of lobsters, the living habits of the three of them are different and cannot help each other, so they are not suitable for breeding together, otherwise it will affect the reproduction and production of the species.

From the perspective of living habits, the two do not conflict, and they can be polycultured, but the space should not be too narrow, otherwise lobsters may cause harm to loaches.

Rice field breeding loach can be mixed with lobster, lobster can be raised in rice field, spring 3 May, first breed and plant early rice, after the seedlings survive, keep the water depth of 20cm mu and put crayfish broodstock 5 75kg and slowly reduce the water level until all drained;

The broodstock that mate and hold eggs enter the cave to ovulate and hatch, and after the rice harvest in autumn, the pond is filled with water, and after about 2 months, some individuals reach the commercial specifications and can be caught and marketed, and most of them reach the commercial specifications in March and May of the following year.

No, you can't....Loaches will eat lobsters....Loaches grow in the soil!

No, the lobster will eat the loaches.
