Experts point out that sea cucumbers, like other organisms, have a great influence on quality. In recent years, with the expansion of sea cucumber aquaculture production and the increase of yield, the issue of seedlings has received extensive attention. The Ministry of Agriculture of the People's Republic of China specifically referred to the construction of the original improved seed system as an important task in the process of advancing the transformation of aquaculture. Come up. The national sea cucumber original seed farm is located in Dalian. In Zhangzidao Town, Changhai County, where sea cucumber is rich in sea cucumber, there is a sea area that has been effectively isolated and no artificially cultivated seedlings have been thrown in. All sea cucumbers are wild populations. The island will naturally become China's supply area for high-quality sea cucumber seedlings.
Latitude 39, the junction between the cold and the heat, is the world’s most recognized latitude and sea origin for the growth of marine life. Latitude 39, passing through Zhangzi Island and the surrounding sea areas, created a story of “natural Zhangzi Island, natural sea cucumberâ€. Many consumers know that the quality of thorns in Zhangzidao is excellent, first of all because of its unique geographical location—the 39th latitude.
The sea cucumber has a distinctive characteristic - "summer sleep". Every summer, sea cucumbers hide under the seabed's crevices and do not eat or drink. They gradually move until the fall. The colder the weather, the lower the water temperature, the more sea cucumbers move. It is frequent. Therefore, the best sea cucumber harvesting season is September and October of each year. At this time, the sea cucumbers have just finished their summer sleep. The body has less impurities, body wall hypertrophy, high nutritional value, and the processing yield is more impressive. According to the announcement issued by the General Administration of Quality Supervision, Inspection and Quarantine No. 167 on the protection of geographical indications for Dalian sea cucumbers, the environmental requirements for the growth of Dalian sea cucumbers are: east longitude 12058' to 12331', north latitude 3843' to 4012'; the average temperature of seawater 12.1°C, the highest 25 °C, minimum 1 °C; tidal range 1.5 meters to 2 meters (maximum 4 meters to 4.5 meters); salinity vertical distribution, an average of 30 ‰ to 32 ‰, rich in nutrients. Located at this latitude, the Zizi Island and its surrounding waters are in line with all the elements of the announcement regulations. The sea cucumbers produced here have a cylindrical shape and are raised on the back. There are 4 to 6 rows of irregularly-shaped conical feet (prickles) on the back; the abdomen is flat, the tube feet are dense, and the arrangement is not very regular. Longitudinal; mouth biased on the ventral side, with tentacles 20; respiratory tree developed, but no home Vichy device; body color was chestnut brown, brown, gray-green and other colors, commonly known as ginseng, sea cucumber.
