1. How to raise freshwater clams

River clams, also known as yellow clams, are a kind of freshwater shellfish. Their shells are medium-sized, slightly equilateral triangles, slightly thick and hard, and the length of adult shells is about 40 mm. The color of the shell surface varies greatly, which is often related to the habitat. It is brown, yellow-green or dark brown, and the shell surface has rough ring ribs. River clams usually live in rivers, lakes, ditches or ponds, live in caves at the bottom of the water, and feed on plankton such as diatoms, green algae or rotifers. They can reproduce all year round. The most abundant period of gonads is from May to August, and the best harvesting and utilization period is 1 to 2 years old. River clams have high economic value, delicious meat and rich nutrition. According to analysis, every 100 grams of clam meat contains 15 grams of protein and 3 grams of fat, and it is also rich in vitamins A, B1, B2, B12, C and iron, calcium, magnesium and other nutrients. In addition, it also contains a certain amount of cobalt and taurine. In addition to being stir-fried, fried, deep-fried, and boiled in soup, clam meat can also be processed into dried clams, canned food, and frozen clam meat. In addition to being a dish, river clams also have medicinal value and therapeutic effects. According to the Compendium of Materia Medica, clam meat can warm the qi and promote urination. According to modern medical books, river clam meat has the effect of clearing away heat and detoxifying. Eating clam meat in moderation can treat carbuncle swelling, damp-heat jaundice, inconvenience, and other symptoms. It is also effective in treating night blindness, promoting maternal milk secretion, and accelerating the recovery of the mother's body after childbirth. The rich vitamin B12 in clam meat has a special effect on the treatment of anemia. The cobalt component contained in river clams also has an auxiliary effect on maintaining the body's hematopoietic function and restoring liver function. Folk records say that drinking clam soup and eating clam meat regularly can also make people strong. Due to the nutritional, medicinal and therapeutic value of river clams, they are not only loved by people in many places in China, but also widely welcomed in Japan, South Korea and some Southeast Asian countries. Therefore, river clams are also an export-earning variety. At present, there are three main methods for developing and utilizing river clams: First, organize fishermen and farmers to catch river clams in appropriate quantities in rivers and waters with resources, which can be carried out all year round or in stages. You can use a scoop net or raking net with a mesh of about 2 cm to catch them. If you operate a single boat, you can catch the big ones and leave the small ones. Second, in order to properly protect natural resources and increase production, you can develop artificial breeding in rivers, lakes and reservoirs. The breeding method is: select a water depth of about 2 meters, sandy and muddy bottom, flat terrain, certain fertility, and rich plankton to stock clam seedlings. When stocking, they are evenly scattered at a density of about 15 kg per mu (specifications 0.5 cm to 1 cm). After 4 to 5 months of stocking, they can grow into commercial clams, and they can be harvested in the same year of stocking. The third is to use ponds for breeding. The pond area is more than 2 mu, the water depth is more than 1 meter, and the bottom is preferably sandy. Before stocking, harmful organisms should be removed and the bottom of the pond should be exposed to the sun for more than 15 days, and then water should be added and 150 kg to 200 kg of farmyard manure such as chicken manure should be applied. About 100 kg of clam seedlings should be released per mu. Clam ponds can also be mixed with grass carp, bream, silver carp, bighead carp and other fish (but not silver carp and carp). After 5 to 6 months of pond culture, river clams will reach commercial specifications, and individuals weighing more than 4.5 grams can be harvested and put on the market.

Seafood delicacies - clams

Nantong borders the Yellow Sea to the east. The 130,000 hectares of mudflats are rich in hundreds of species of shallow-water shellfish, especially Manila clams, which account for one-third of China's exports.

Manila clams are known as "the most delicious seafood in the world". They belong to the class of gills and clams. Li Shizhen of the Ming Dynasty said: "Among all the clams, those that are more beneficial than others are collectively called clams. They have white shells and purple lips, or have patterns on their shells, so they are called Manila clams or flower clams." The Song Dynasty poet Mei Yaochen also wrote a poem "Che scorpion and moon clam, sent from Hailing County". When Emperor Qianlong of the Qing Dynasty went to the south of the Yangtze River, he ate Manila clams in Suzhou and named them "the most delicious seafood in the world".

Manila clams live on shallow sea beaches with low salinity. They are dioecious, and their gonads mature from June to July. The sperm and eggs produced are fertilized and hatched in the seawater. The young clams go to the sand bottom to live after three weeks. It takes two to three years for young clams to grow up and be harvested. Young clams are carried by the tide to the mudflats more than ten meters deep. The most suitable water temperature is 15-25 degrees. They feed on algae and plankton. When they grow up, they gradually migrate to the subtidal zone. They usually show their bodies on the sand surface. In winter, they dive to about 20 to 30 centimeters below the sand bottom to hibernate, but they have pores for ventilation.

The shell of the clam is like a colorful fan, and its meat is very tender and nutritious, containing 10% protein, 11.2% fat, 2.5% carbohydrates, and calcium, phosphorus, and amino acids necessary for the human body. It tastes fresh and not vulgar, and you will never get tired of eating it. Eating clams can stimulate appetite, promote lactation, and keep fit. It also has the functions of clearing heat, resolving phlegm, promoting dampness, and dispersing clams. The colorful bakers can be used as exquisite packaging boxes for clam oil, and can also be made into handicrafts for elegant halls.

There are many ways to eat clams. They can be used as a main dish, stir-fried quickly over high heat; or as a side dish to enhance color and flavor; or marinated with seasonings and eaten raw; or chopped into meat paste and fried into cakes. In recent years, Rudong Pharmaceutical Factory has developed it into a powdered product, named "the world's best fresh food", which is famous both at home and abroad.
