Many people say that Dalian sea cucumber is better than Shandong sea cucumber, but it is not unreasonable that everyone has formed such an idea for a long time. Because everyone just started eating sea cucumbers, most of them are Dalian sea cucumbers, and they are gradually recognized by everyone. The most important thing is that the publicity of Dalian sea cucumber is much earlier than that of Shandong and Fujian sea cucumbers, and the publicity is stronger, so Dalian sea cucumber is better in the minds of many consumers. At the beginning of the sea cucumber industry, the sea cucumber in Dalian was really very good, but in recent years, sea cucumber has brought more and more benefits to everyone, and more and more people eat sea cucumber, which has also created the development of sea cucumber breeding industry.

Once sea cucumbers are cultured in large quantities, we can't generalize that Dalian sea cucumbers are all good sea cucumbers. Now, to judge the quality of sea cucumber, we should determine which sea area is in Dalian or Shandong, because there are large areas of aquaculture sea areas in Dalian and Shandong. The way of cultivating sea cucumbers is different, and the quality may vary greatly. At present, the sea cucumbers with better quality are mainly produced in four places. The quality of sea cucumbers produced by several affiliated islands in Changhai County of Dalian and Changdao County of Shandong Province is the best in China. In foreign countries, the quality of six rows of red ginseng in Hokkaido, Japan is the best.
