Many farmers usually like to eat shrimp, and think that the shops are too expensive to sell, so they want to enter this industry by themselves. So today I will talk about how to raise it by the way.
If you want to raise prawns, you must first make a good pond.
Let's take a pond of 0. 13 to 0.2 hectares as an example, and ensure that 1.5 to 2 meters deep. The bottom of the pond should be flat, leaving about half a foot of silt. In addition, a ditch should be dug next to the pond, 4 meters wide and half a meter deep, mainly to enclose the pond, because shrimp can easily jump out. At that time, it jumped into this ditch and fished it back when it patrolled every day. Not without digging ditches. It jumps directly to the ground and easily dies of thirst. Of course, if it loves to jump, you can let it die.
It is common sense that pond water is running water. But before you get the shrimp in, you must kill all kinds of other creatures first. Fish, for example, and some animals that catch shrimps were killed. You can fish seriously once. Sprinkle limewater in the pond half a month before shrimp harvest, with a minimum of 200 kg and a maximum of 300 kg per mu. Depends on how much you want to sprinkle, mainly disinfection. In order to give shrimp food, balance the lime water sprinkled before, and get the same weight of organic fertilizer into it.
A week later, you take water samples and observe whether there are enough plankton and enough shrimp under the microscope. If you think it's ok, you can throw the new prawn seedlings into the pond.
If you don't have a pond, but there are many paddy fields, don't worry. I'm here to introduce you to the method of planting rice and raising Penaeus monodon at the same time
You know, not all rice fields can raise shrimp. The requirements are as follows: 1. Running water. 2. The water quality is good. 3. The area is more than two acres, eight acres at most, and it is not good if it is too big. 4. In order to prevent the shrimp from jumping away, a circle of ditches should be dug around the rice field, and the requirements are the same as above. And whether you use ponds or paddy fields, you must install two nets at the entrance of running water to prevent the shrimp from running away.
Similarly, the paddy field should be treated with lime water, and the dosage is the same as that of the previous pond. The purpose is the same. It is also the same requirement to add organic fertilizer afterwards. In addition, if you want to raise shrimp in rice fields, you should also have certain requirements for rice seeds. After all, if there are many shrimps in it, you must use lodging-resistant varieties. In addition, if you raise shrimp, you must not use pesticides. The ability to resist diseases is also important. As for transplanting rice seedlings, it is just like ordinary rice fields.
At this time, we can talk about how to put shrimps in ponds or fields. Because its original living environment is in the sea, and we are raised inland, we can't always bother to transport seawater. Especially in the field, you know, our high salinity rice cultivation method has not been popularized, so it is impossible for us to introduce seawater into the field.
It is necessary to desalinate Penaeus monodon to adapt to fresh water. Desalination is nothing more than slowly reducing the salt content in water and making it gradually adapt. When it is desalinated, just the day before it is thrown into the pond or field, use two or three centimeters of shrimp seedlings to test the water for a long time to see if it is dead. If you live healthily, it means that these shrimps can adapt to your water here. So how many shrimps can be put in the pond? There are 8 to 65438+ ten thousand birds per mu, and rice fields are half of the former.
So how should we feed these shrimps?
Feeding special bait, of course. Feed 5% of the shrimp you threw at the beginning every day. As the shrimp grow up, slowly throw more. The standard is to let them eat it in two or three hours. Excessive feeding will affect the water quality.
In addition, if it is summer, it will become more edible, and the amount can be appropriately increased by 40%. In terms of food, you can generally throw some smashed miscellaneous fish and snails. When you have time, you can add some vitamins and bone meal to the bait to make them grow stronger. In terms of time, feed one third during the day and the rest at night. If it is a time of rapid development, start a small stove in the middle of the night.
