Do you make money by raising river crabs?

As the economic input of raising scallop is relatively large, many farmers do not dare to breed it easily, so what is the market prospect of breeding scallop? Whether it's worth breeding. Let's take a look at the following analysis.

Scallop is a bivalve animal, its shell is fan-shaped, like a fan, hence the name of scallop. It is one of the precious sea treasures, which is distributed along the coast of China. In the past, it mostly depended on fishing for natural resources. In recent years, artificial culture has been developed in various coastal areas. The main cultured species include the original chlamys farreri, the Japanese scallop introduced from Japan and the bay scallop from the United States. Scallops are generally harvested all the year round, but the quality is better in spring.

The shells of scallops are purple-brown, light brown, apricot yellow, reddish brown or gray-white, etc. in the sea, scallops are usually attached to rocks, gravel, shells, coral reefs or other objects, and some of the following shells live on the sandy bottom of the sea. It has its footprints from the shallow sea below the tide line to the deep sea of 5000 meters. It likes to live in groups, often individuals are involved with each other, one by one, can form a natural scallop field. It is observed that it takes about 3 years from spawning to adult scallop, and it takes about 19 months for the scallop to grow rapidly, but the bay scallop with the fastest growth rate can be harvested and put on the market in the same year.

It is understood that at present, the culture techniques and methods of scallop in China have become increasingly mature and easy to master. According to different conditions, floating raft culture (including cage culture, tube culture, ear-piercing culture) and submarine sowing and multiplication are mainly used. According to reports, with the continuous progress of scallop breeding and culture technology, large-scale and industrial culture has become a reality. Take Shanyi scallop as an example, since it was introduced from Japan in the early 1980s, artificial breeding and culture techniques have been mature after cultivation and popularization in recent years, and now it has gradually formed large-scale and industrial culture in the northern part of the Yellow Sea. Among them, Changhai County of Dalian has the largest culture scale, which has created an output value of 1 billion yuan in the past 10 years, and achieved high economic and social benefits. Therefore, the benefit of developing scallop culture is considerable, and when the yield per mu is high in some places, it has reached 2500 kg ~ 3000 kg. Therefore, scallop is a famous and excellent variety with good prospects for development.

The economic value of scallop is very high, it has well-developed adductor muscle (meat pillar). In addition to fresh food, in order to keep fresh and transport conveniently, most of their adductor muscles are taken out and frozen and sold everywhere, which is called frozen scallop column or frozen fresh shellfish. It is an important cooking material for middle and high-end hotels, restaurants and restaurants, and it is entering urban families. The dried product "dried scallops" made from the closed shell muscle of scallops is a valuable seafood and is one of the eight treasures of seafood. The meat of scallops is delicious and nutritious. According to analysis, it is rich in protein, carbohydrates, riboflavin, calcium, phosphorus, iron and other nutrients. The protein content of dried scallops is as high as 61.8%, which is 3 times that of chicken and beef and 2 times higher than that of fresh shrimp. According to records, scallop also has anti-cancer, soften blood vessels, prevent arteriosclerosis and other medicinal effects. And its cooking can take both dry and fresh taste, can produce a variety of delicious and delicious delicacies.

The development of scallop in China has a certain foundation, the annual output can reach more than 960000 tons, in 2001, domestic sales of more than 800,000 tons, exports of more than 100000 tons, but there is still great potential for development. In China, in addition to the coastal large and medium-sized cities as the main point of sale, with the accelerated pace of western development, the demand for sea treasures in inland areas will increase greatly. at the same time, after China's accession to the WTO, the international market will further open up, and the export of scallops will also increase greatly. According to the analysis of experts, in the next three to five years, the domestic demand for scallop will reach 1 million tons, and the export volume will reach 500000 tons, which is still 500000 tons short of the existing output. The price of scallops is better, such as in the Guangzhou market, fresh shellfish with shells is 12 yuan per kilogram, dried products and dried shellfish are of different sizes, and the retail prices per kilogram are 116 yuan, 136 yuan, 156 yuan, 176 yuan and 216 yuan respectively. Therefore, cultured scallop not only has a bright future, but also has a broad space for development.
