Adenophora stricta Miq.

Stichopus japonicus, also known as Adenophora adenophora, is the most valuable sea cucumber. Stichopus japonicus in Lianyungang is yellow-brown, with four rows of big thorns and four rows of small thorns. Stichopus japonicus is not resistant to high temperature and dormant in summer, which is the capture season. Stichopus japonicus has extremely high nutritional value. Every 100g of Stichopus japonicus contains 76.5g of protein, 1.1g of fat, 3.4g of inorganic salt and 10.7g of carbohydrate. Cystine and arginine needed by human body can also be obtained directly from it. Stichopus japonicus is delicious, and it is regarded as a high-class delicacy in banquets, and enjoys the same reputation as bird's nest as a nourishing medicine. Now the first three islands in Lianyun District are already sea cucumber breeding bases. In winter and spring, when it is calm, the sea water is clear between the reefs of the islands, and the black and round sea cucumbers squirm in the water, which is really beautiful and a scene of the island.
