Culture method of belt

Scallop is a common aquatic shellfish, which is widely distributed in the coastal areas of China. It tastes soft and smooth, and many people like it very much. It also belongs to a kind of precious seafood in our country, and now our country has gradually begun to breed the scallop. However, because it is shellfish, many people do not know how to raise it, the following editor will give you a brief introduction, let's have a look!

1. Site selection

We should pay attention to observe the growth habits of the tapes before culturing the tapes, which have different growth environment requirements at different growth stages. Therefore, when we choose the site, we should pay attention to the environmental and biological factors of the aquaculture area. For example, water depth, salt temperature, etc., to ensure the suitability of the belt to the farm. Farms are generally divided into different culture areas according to different growth stages of the belt, such as seedling collection area, seedling breeding area and so on. And also to ensure that the farm production is convenient, transportation is convenient, and it is convenient for production and later transportation.

2. Artificial breeding

After a long period of artificial breeding, there are now some artificial seedlings, such as long oysters, European oysters and so on. Compared with wild breeding, artificial breeding is more commonly used now. First of all, we should do a good job in parent shellfish culture, strengthen management, do a good job of artificial insemination of parent shellfish, and improve the success rate of tape fertilization. When the parent shellfish successfully lay eggs, it is necessary to do a good job of raising larvae. The breeding cost of artificial breeding is relatively low. The main purpose is to control the living conditions of the belt, make use of the growth period of the belt, promote the growth of the belt and cultivate excellent varieties.

3. Nurturance management

There are many kinds of tape cultivation and management, generally dominated by the sea floor type. First of all, the seedlings of the belt should be sprinkled on the sand on the bottom of the sea during the tide on the sea floor. Pay attention to density, which can also be understood as the "sowing" of the tape. Before sowing seedlings, we should pay attention to loosen the soil to avoid the existence of enemies, and then dig a good protection ditch. For sectional breeding, the cost of undersea cultivation is very low, and it is the longest method used by major farmers. However, its growth rate is slow, and the threat of being harmed by the enemy is relatively large, so it depends on the actual situation.

4. Fattening management

After the cultivation period, the tapes can actually be harvested and put on the market, but in order to improve the quality of the tapes and increase the output. We should try our best to do fattening work before harvest, first of all, move the belt from the nurturing area to the fattening farm. To promote the growth of the ribbon, the fattening farm should ensure that there is sufficient bait. Under the condition of sufficient bait, even if the management is relatively extensive, the ribbon can reach high quality after growing for about 2 months. And the belt can also be moved near the low tide line to increase the feeding time of the belt and promote the fattening of the belt.

The above is a brief introduction to the methods of belt culture, belt culture is very simple, but we should pay attention to the prevention and control of enemy damage, otherwise the threat to the growth of the belt is very great. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
