Do you like to eat seafood? Especially shellfish, common are red shellfish, salamander shellfish, field snails, conch, clams, clams and so on.
Because it contains B vitamins and calcium, phosphorus, iron and other trace elements, it is favored by consumers.
But have you ever eaten the following shellfish?
Pig ear clam, dorsal tumor clam, giant head wedge mussel, fishtail wedge mussel, dome bead mussel and olive clam mussel. Listening to these names, is there a feeling of "tall"?
Not only do they have a tall name, they also taste good, because they are carefully cultivated.

Successfully broke through the artificial breeding technology of 6 kinds of freshwater shellfish such as pig ear clams
This technology was developed by Anhui Shuiyun Mollusk Breeding Technology Co., Ltd., located in Wuhu.
After long-term careful planning and preparation, on the basis of extensive investigation and collection of seed sources, the joint research team composed of the company's chief engineer Zhan Mingfei team and the team of Professor Shu Fengyue of Qufu Normal University in Shandong Province has realized the artificial breeding of pig ear clams, dorsal tumor clams, giant head wedge mussels, fishtail wedge mussels, dome bead mussels and olive clams, filling the gap in China's artificial breeding technology of freshwater shellfish.
In the shellfish breeding base, a variety of different shellfish breeding ponds are neatly arranged, labeled, pumped to replenish the breeding pond, and workers regularly clean the pond to remove weeds and necrotic shells.
"In particular, the success of artificial breeding of rare and endemic species such as pig ear clams has provided key technical support for the protection of freshwater shellfish species resources and the restoration of ecological environment." Up to now, the company has realized the artificial breeding of 12 kinds of shellfish, with an annual breeding scale of more than 50 million, which has a great impact nationwide. Zhan Mingfei said.

The shellfish market has a broad prospect and there is much to do
Among these shellfish, olive clams are rare species endemic to China, with special breeding conditions, delicious processing taste, and broad industrial prospects.
Olive clams are widely distributed in the waters of the Huai River in Fuyang City, with high economic value, and are known as "Huai River abalone".
In recent years, the endangerment of this species has intensified, and conservation, development and utilization are imminent. In 2017, the National Aquatic Germplasm Resources Conservation Area of the Fuyang Section of the Huai River was approved, and subsequently, the fishing of the olive clam was included in the government management, and individuals were not allowed to fish without authorization.
Now don't worry, the artificial breeding technology of olive clams solves this problem. "Now olive clams have the best sales, the market price is 70 yuan / catty, and the supply is in short supply." We are preparing to expand so that more Wuhu citizens can taste the delicious taste of 'HuaiHe Abalone'. The breeding staff introduced.
Small, large-yielding shellfish can be used as fertilizer for farmland and feed for poultry and livestock. The main ingredient of the shell is calcium carbonate, which is the raw material for firing lime, and can also make paint blenders, shell carvings and other arts and crafts, and pearls are valuable ornaments.
In addition, the cultivation of rare shellfish species, strengthening the protection and development and utilization of characteristic aquatic biological resources, helping to alleviate poverty, promoting rural revitalization, and driving the development of local labor employment and rural tourism service industry have played a great role in promoting.

Water scavengers make the water in Wuhu clearer and greener
Why are freshwater shellfish "water scavengers"? They are a key component of freshwater ecosystems, have great market potential in water purification, ecological restoration and industrialization of economic varieties, play a vital role in maintaining the balance of water ecosystems and biodiversity, and are the preferred varieties for environmental remediation.
At the same time, the life history of mussels is very special, and the larvae need to host to the fish body to complete the metamorphosis process, so fish play a decisive role in their population reproduction.
Freshwater shellfish are hosts of fish pups in specific populations in the waters, and the number of shellfish plays a decisive role in the reproduction of these fish.
Shu Fengyue, a professor at Qufu Normal University in Shandong Province, said, "Wuhu is located in the middle and lower reaches of the Yangtze River, with a dense river network and abundant freshwater resources. In the process of practicing the treatment of black and odorous water bodies, we discovered the unique role of freshwater shellfish, so we began the research and conservation breeding of freshwater shellfish.
