Why choose Liaoning sea cucumber of 39° north latitude?

Dalian sea cucumber is also known as Liao sea cucumber, and its sea area is located at 39 degrees north latitude, which is recognized by the world as the most suitable for the growth of marine life. Liao sea cucumbers that have reached the age of 3 can meet the harvesting standards and be caught ashore. This kind of marine life that seems to have no self-protection ability has actually lived on the earth for more than 600 million years, and it is properly a "marine living fossil"!

How big is a sea cucumber just out of the water? Dalian catches 50,000 tons of sea cucumbers every year. Calculated at 5 heads per catty of fresh and live sea cucumbers, it is about 500 million heads, accounting for about 30% of the country's total. The annual output value of the entire industrial chain is more than 20 billion yuan.
