Clams are a seafood we often eat. How much does it cost to farm clams?

Chinese clams, commonly known as "yellow clams" and "flying clams", belong to the genus Clam, Cladocera, Bivalvia, Heteropoda, Cladocera and Clam. There are more than 30 species in 8 genera, including clams, otters, clams, clams, clams and clams, clams, clams and clams. Among them, there are three most common economic species, namely stone tongue, square clam and clam. Cladocers are distributed worldwide, mainly distributed in countries and regions such as the west coast of North America, Canada, Australia, France, Indonesia, Thailand, Vietnam, Japan, South Korea, the Philippines, China, especially China, Japan, South Korea and Australia. Chinese clams are mainly distributed along the coasts of the Yellow Sea and Bohai Sea in Liaoning and Shandong. According to the "China Fisheries Statistical Yearbook 2019", the production of clam farming in Liaoning Province in 2018 was 1.264 million tons, 434,000 tons in Fujian Province, and 368,000 tons in Jiangsu Province.

Clam farming has good economic benefits. Clam farming can effectively fix and transfer carbon in seawater, and has a positive impact on the ecological environment. In recent years, due to the influence of the marine environment, the area of ​​clam farming in my country has declined. In 2018, the area of ​​clam farming in China was 383,000 hectares, down 8.9% from 417,000 hectares in 2017. Clam farming in my country is mainly distributed in Liaoning, Shandong and Jiangsu. In 2018, the area of ​​clam farming in Liaoning Province was 139,000 hectares, Shandong Province was 112,000 hectares, and Jiangsu Province was 71,800 hectares. Cultivating swimming crabs: Compared with our brothers who have experienced big winds and waves, our "captive" crabs are not inferior. In the past five years, the price of our crab farming has been relatively stable with little fluctuation. This year, the wholesale price of half a catty of swimming crabs is about 50 yuan per catty, and the market retail price is more than 70 yuan per catty. The price of three or four crabs is slightly lower, with a wholesale price of 30 to 40 yuan and a retail price of about 50 to 60 yuan. The yellow crab is harvested later, usually starting from late October, and the price is slightly higher, with the retail price reaching more than 80 yuan per catty. This price is higher than that of crabs in the south, and we are all top fat!

Farming swimming crabs: Jimo has a history of crab farming for more than 20 years, mainly distributed in coastal mudflats such as Fengcheng and Tianheng, covering an area of ​​about 5,000 acres. It is the main production area for farmed crabs in Qingdao. After spring every year, conservationists will catch wild female crabs from the high seas for breeding. So most of the farmed crabs are seedlings cultivated in local nurseries. Farmers generally start to release seedlings in the first half of May. From the end of September, as the water temperature gradually decreases, our activities will become fatter, the meat will become more and more delicious, and the harvest period can last until November. Compared with catching crabs in the sea, our captive crabs seem to have much less competition for survival, but our nature is aggressive. When we were crab seedlings, we would push and fight each other with crab claws, which could easily cause casualties. Farmers will mix us with husks during transportation to reduce our chances of fighting.

Farming swimming crabs: three meals a day, one in the morning and one in the evening. The menu is very rich: clams the size of rice, mussels, miscellaneous fish, clams, etc., 1.5 yuan per pound. Farmers rarely feed us those ready-made artificial feeds, and we don’t like to eat them. When farmers raised our little crabs, they were only as big as small green beans and looked like babies. If they don’t pay attention, many of them will die. They have to boil the fish, cut them into thin strips one by one, and then feed them to the fish. Taking care of us is no easier than taking care of children. When we can crack the clam shells and eat the meat, the farmers’ breeding began to "lighten the burden".

The cost of breeding clams should be less than 100,000 yuan, and the sales volume is very good. Nowadays, many young people like to eat these things very much.

The cost is generally around tens of thousands of yuan. The investment cost for breeding seafood like this is very high, and some related equipment is also required.

First of all, it depends on how much you want to raise. Generally, around 100,000 yuan is enough. The breeding cost is not particularly high, and the rate of return is still relatively high.

About 10,000 or 20,000 yuan. The specific situation depends on the number of clams that need to be cultivated. Also, there are many procedures required in the cultivation process, and only by mastering them can you raise clams well.

The benefits vary according to the breeding season. When is the best season to start breeding clams?

Clams are a kind of seafood that people often eat nowadays. Its meat is delicious and is known as the best in the world and the best in various flavors. It is also relatively comprehensive in nutrition. It contains vitamins, amino acids, taurine and other ingredients. It also has the characteristics of low calories, high protein, and low fat, which can prevent and treat chronic diseases in middle-aged and elderly people. Clams are one of the four major farmed shellfish in my country and are deeply loved by consumers.

With the increase in market demand, its breeding area has gradually expanded. Clams, also known as Manila clams, are delicious and nutritious, and are the main species of tidal flat farming in my country. Clams grow very fast and are cultivated in coastal areas in northern and southern China. The growth rate of clams is closely related to the season, individual size and living environment. In the coastal areas of Shandong, the breeding period of clams is from June to August. The peak spawning period is from late July to early August. The growth rate of adolescents is faster within one year, and then gradually slows down with age. The shell can grow to about 2.5 cm in one year, more than 3.0 cm in two years, and sexual maturity can be achieved in about two years.

Clams are not only delicious, but also more nutritious, and are a cheap seafood. It is rich in nutrients such as protein, fat, carbohydrates, calcium, iron, phosphorus, iodine, vitamins, amino acids, taurine, etc. It is a high-protein, low-calorie food. Clams are the best food for preventing and treating chronic diseases in the elderly. Clams are cold, and the spleen and stomach are cold, and urination is taboo for diarrhea; people with stomach cold and abdominal pain should not eat, women during menstruation and postpartum diet; people with colds should not eat. Eating clams generally has the effect of nourishing yin, moistening dryness, diuresis and swelling.

It has the effect of nourishing yin and moistening dryness. It can be used to treat yin deficiency, internal heat, and thirst. It has a diuretic and detumescent effect. Clams are cold in nature. Entering the bladder channel, it can dredge the water channel, clear the heat of the bladder, and is conducive to the effect of water detumescence. It can be used to treat edema, metrorrhagia, and dysuria. It contains a kind of cholesterol and 24-methylene cholesterol, which has the effect of lowering serum cholesterol. They have the unique effect of inhibiting the synthesis of cholesterol in the liver, accelerating the excretion of cholesterol, and thus reducing cholesterol in the body. After eating clams and shellfish, people often have a refreshing and pleasant feeling, which is undoubtedly helpful to relieve some symptoms of irritability.

The most suitable time is just after the beginning of autumn, because the feed is more sufficient at this time, so the quality and yield of clams can be improved, and the meat is also particularly good.

Of course, it is in the summer. This season is very suitable for the growth of clams. The clams farmed during this period are very delicious, and many people like to eat clams very much.

Clams can be cultured in the summer because the feeding activity of clams is very strong in the summer and the growth rate of clams is also very fast.

It is most appropriate to start breeding in autumn, because the living environment of this animal is relatively special, so it would be more reasonable to breed it in autumn.
