New prospect of beach shellfish culture in Liaoning Province

Introduction: Xinhua news agency, Shenyang, Sept 7 (Wang Yan, Lin Changle) recently, the artificial breeding of variegated clam seedlings undertaken by Liaoning Institute of Marine Fisheries passed the acceptance organized by Dalian Science and Technology Commission This scientific research achievement not only achieved the breakthrough of "zero" in artificial breeding of the northern variegated clam, but also showed a broad development prospect for the cultivation of seashells in Dalian and the province The scientific name of variegated clam is Philippine clam, which is also commonly known as sand clam These humble clams are now the most popular in the international market, especially in Japan In recent years, with the rapid reduction of natural seedlings, Liaoning Province has to pay a lot of money to buy Artificial Breeding clam sand seedlings from the South or even abroad every year However, due to the low quality of sand seedlings and the inadaptability to the local beach environment, the mortality rate is very high, which not only directly increases the breeding cost of the farmers, but also makes the beach shellfish breeding industry in the whole province into a dilemma, and the export volume is sharply reduced After nearly 90 days of hard work, a team of five experts from Liaoning Institute of marine fisheries has successfully bred 1.176 billion clam sand seedlings in 468 square meters In the near future, these seedlings will be released to the beach for large-scale production Liaoning Province is a large marine province, with a coastline of 2920 kilometers, nearly 3 million mu of shoal and 1 million mu of abandoned shoal, which has great potential for beach and shellfish farming The success of artificial breeding of clam will become another new economic growth point of "Liaoning on the sea".
