1, feet
Wild sea cucumber: Generally, it grows in the depths of the seabed about 20 meters away from the sea surface. Because in the present environment, sea cucumber crawls through its feet to find food, so its feet grow thick and have strong adhesion.
Cultured sea cucumber: Because long-term consumption of artificial bait does not need to move, living in shallow water captivity or artificial ponds, the environment is relatively stable, so it is not affected. Therefore, the mobility of its feet is reduced, and the adhesion is poor and small.
2. Shazui
Wild sea cucumber: Living in the deep sea, the food source is sediments on the seabed, of which sea sand accounts for a large proportion. Due to long-term consumption of sea sand, the sand mouth is big and hard.
Cultured sea cucumber: The food source is artificial bait, so it doesn't need to be actively fed, so the sand mouth is much smaller than the wild sea cucumber.
3. Meat quality
Wild sea cucumber: Because it grows in the deep seabed, it needs little time to bask in the sun, so it grows slowly. However, it needs to resist the influence of living environment such as ocean currents, so the meat is thick and elastic, the tendons are wide and full, and the deposited nutrients are very rich.
Cultured sea cucumber: the feed is large, the hormone ripens, grows quickly, and the meat is soft but not tight.
4. Form
Wild sea cucumber: it is a rotating cone (or a bit like an ellipse), but it is thin at both ends and a little thick in the middle. Typical short and fat, looks very strong, and the longer the sea cucumber, the more obvious this feature.
Cultured sea cucumber: it is slender and lacks toughness, especially the sea cucumber cultured in hanging cages in the south, which is almost as thick as human fingers.
Step 5 stab
Wild sea cucumber: The living environment is very bad, so it needs to resist the erosion of bad environment and water, so the thorns on the back and sides of sea cucumber are very thick.
Breeding sea cucumber: The living environment is very stable, so the sea cucumber is slender and has no strength.
6. Years of growth
Wild Stichopus japonicus: It usually takes more than 3 to 4 years to reach the fishing standard. The longer it grows, the more nutrients it deposits, and the greater its nutritional value.
Breeding sea cucumbers: In order to achieve the goal of rapid sales, farmers will quickly fatten sea cucumbers by feeding hormone feed, which can be caught and sold in one year, and its nutritional value is self-evident.
