I. Culture environment

Oysters are creatures that stay in the sea, and they don't really lie motionless in the sea, so this aquaculture environment with the sea is very important. the most important step in the real cultivation of oysters is this sea problem. In fact, they have to filter the sea water. An adult oyster can filter five liters of water in about an hour.

II. Reproductive problems

1. Generally speaking, they need to reach the age of two before they can reproduce, and the reproduction is carried out in the sea. Both male and female oysters need to be put into the sea water of about 25 ℃. The female oysters discharge eggs into the sea water, and the male oysters discharge sperm, and then the fertilization process ends in the sea water.

2. Under normal circumstances, the fertilized eggs that have just been completed cannot be seen directly by the body, and it takes more than two days to be possible. Here is an advantage of breeding oysters, that is, they do not need to feed some food like the sea water. That is to say, oysters can get food on their own, even for newly born oysters. Before allowing them to produce fertilized eggs, they should plan this range. Cover with a cylinder, the natural purpose is to prevent small raw oysters from running out.

3, as big as a month and a half to see some tiny raw oysters, at this time they can be transplanted to a safe area without waves, during this period basically do nothing, just wait for them to grow up, wait for them to grow up, wait until another five months or so can put them into the filter, and then soak in the sea, about three months can grow to the length of 5cm.

4, the basic cultivation in the early stage is here, even if it is completed in the middle, there is only some trouble, but it is not complicated. For farmers, raising oysters is really a way to save time and get rich.

III. Receiving and salvaging

1. Although it is a harvest, some of these oysters are small, so you need to pick them out, take the big ones out and sell them, and put the small ones back into the mud so that they can continue to grow, and don't fall hard in the process of picking. Even if their shells are hard, they are easy to crack directly.

2. After that, they can be salvaged, and after they are transported to some places where the waves are relatively small, they are required to have a certain thickness of silt, and these raw oysters need to be put into the silt so that they can grow in it for about half a year. After half a year, we can begin to harvest.

3. Then the last step is to put these selected oysters in a special sea water with a sterilized environment, let them live in it for two or three days, and clean up all the bacteria and other things inside. Then it can be transported to the market for sale.

All right, the above is the way of oyster farming brought by the editor of Tuliu.com. I hope it will be helpful to you. I'll see you next time.
