How to distinguish between wild and captive bred sea cucumbers?

A method of distinguishing whether sea cucumbers are wild or farmed.

1. Bottom foot: Wild sea cucumber generally grows in the sea area with a water depth of about 20, and looks for food through the action of the bottom foot, so the bottom foot is short and stout; However, captive sea cucumbers do not need to move because of the long-term use of bait put by breeding personnel, and they live in shallow water, so the action of the bottom foot decreases, the adsorption capacity is poor, and it becomes slender.

2. Sand Spit: The sand spit of wild sea cucumbers is large and hard.

3. Fleshy quality: wild sea cucumbers grow slowly because of their deep growth waters, low water temperature, less sunshine, thick and elastic flesh, wide and full tendons, and rich nutrients deposited; Captive sea cucumbers grow quickly, and the flesh is soft and not firm.

4. Shape: Wild sea cucumber is spindle-shaped, with two tips and thick in the middle, short and thick, and looks very strong; And captive sea cucumbers grow slender and lack tenacity.

5. Back stabs: The spines on the back and sides of wild sea cucumbers are the same thick, while captive sea cucumbers may not be the same thickness and length of the spines on the back and sides due to the influence of the growth environment, and the slender spines appear to have no sense of strength.

6. Growth period: wild sea cucumber generally grows for more than 4 to 5 years to reach the fishing standard, the longer the time, the more nutrient deposition, the greater the nourishing value; Captive sea cucumbers only fertilized and sold in one or two years.

The efficacy and role of sea cucumbers.

Sea cucumber contains a large number of amino acids and trace elements, all of which are essential for the human body, so the nutritional value of sea cucumber is very high, and long-term consumption is very useful for the supplement of essential nutrients for the human body. Sea cucumber has a tonic effect and high nutritional value. From the perspective of medicinal use, there are also many nutrients and medicinal ingredients, as follows:

1. Repair deficiency: It is very useful for physical weakness, postpartum blood deficiency or post-illness conditioning and postoperative conditioning;

2. Sea cucumber is rich in calcium, as well as vitamin D, which can prevent osteoporosis and has a very strong preventive effect on senile diseases;

3. Heart-nourishing effect: It is to protect the heart, because sea cucumber is low in fat, which is very, very useful for regulating lipid metabolism;

4. Sea cucumber has a certain degree of reproductive regulation, has a certain sex hormone effect, and has a certain supplement to male and female sexual function, especially for the elderly with kidney deficiency, or senile sexual dysfunction, eating sea cucumber is also helpful.

The methods of distinguishing wild and farmed sea cucumbers are as follows:

1. First of all, the spines of wild sea cucumbers are different.

Wild sea cucumbers are black-brown in color, like a small mallet, with regular spines, about 4 to 6 rows. Wild sea cucumber has thick skin and collagen.

High content and full of elasticity. Captive sea cucumbers are yellowish-green in color, thin in skin, and low in collagen.

2. Secondly, the suckers of wild sea cucumbers are different.

Wild sea cucumbers have a large number of suckers on their abdomen, which are short, thick, and very powerful. Because wild sea cucumbers grow in the deep sea area and the current is fast, the sea cucumber must hold the sand and gravel on the bottom of the sea tightly in order to lie firmly on the bottom of the sea.

For a long time, wild sea cucumbers had many suckers, which were short, thick and powerful.

The amount of suction cups in captivity is small, thin and long. Sea cucumbers in captivity are grown in shallow waters or in captive ponds.

The flow of water is small, and the sea cucumber can be easily fixed on the seabed or rocks, so the suction cup is thin and long.

3. There are differences in the shape of wild sea cucumbers.

Wild sea cucumbers grow in the wild, the sea water is deep (26-27 meters), there is no fixed bait, and the growth is more than three or five years, and the sunshine time is long, the color of the sea cucumber is dark gray, the flesh is thick and the skin is thin; The captive sea cucumber needs to be fed regularly and quantitatively, the sea cucumber grows fast, most of them can grow into a ** body shape in one or two years, the color is mostly dark yellow, bright, thick skin and thin meat.

The appearance of sea cucumbers grown in the wild environment is relatively complete, and the skin of sea cucumbers will not be scratched; Most sea cucumbers in captivity have scratches on the outside. This is because when fishing sea cucumbers, most of the sea cucumbers in the deep sea are on the sand and gravel or in the hanging nets of sea cucumber farming, which are easy to catch. Most of the captive sea cucumbers lie in the cracks of solid rocks, which are not easy to catch, and they can only be obtained with special tools and quick shoveling, which is easy to hurt the sea cucumbers.

4. Differences in color.

The color of each sea cucumber is different for wild sea cucumbers, but the color of sea cucumbers is the same for farmed sea cucumbers.

5. The taste experience of wild sea cucumber farming is different.

Wild sea cucumber. It is very resistant to cooking, even if it is boiled for a little longer, it will not have much effect, and the boiled sea cucumber body is elastic, the spines are transparent, the flesh is tendony, there is a bite head, and the taste is good. Captive sea cucumber is not resistant to cooking, and it will become naan after cooking for a long time, and the meat lacks toughness and has a bad taste.

6. There is a difference in the cultivation of sea cucumbers in wild seas.

Traditionally, wild, bottom-sown sea cucumbers** are much higher than shrimp ponds and cofferdams.

Cultured sea cucumbers**. Generally speaking, the nutrition of wild sea cucumbers is far better than that of traditional cultured sea cucumbers, such as shrimp pond culture and cofferdam culture, but there is only one kind of cultured sea cucumber that can be comparable to it, that is, bottom sowing and proliferation, the so-called bottom sowing and proliferation is to put sea cucumber seedlings back into the sea and let them grow naturally.

Distinguishing whether sea cucumbers are wild or farmed is mainly from these aspects: looking at the thorns on the body, looking at the suckers, looking at the body, and making the taste.

1. Look at the thorns on your body

In appearance, the wild sea cucumber is black-brown in color, mallet-shaped, with 4 to 6 rows of spines, and the spines are regular. Sea cucumbers have thick cortices, and such sea cucumbers have a high collagen content and dense tissues. The captive sea cucumber is yellowish-green in color, has a thinner cortex, a lower collagen content, and sparse tissues.

2. Look at the suction cups

Sea cucumbers are adsorbed on the seabed by the suckers of the abdomen, and the number of abdominal suckers of wild sea cucumbers is relatively large, usually short, thick and powerful, and the number of captive sea cucumber suckers is small, and it looks more thin and long.

This short, thick characteristic of wild sea cucumber is mainly due to the rapid current in the deep sea, if the sea cucumber wants to lie firmly on the bottom of the sea, it must firmly suck the rocks on the bottom of the sea, and in the long run, the sucker of wild sea cucumber is more, short, thick and powerful. Captive sea cucumbers, due to the small flow of seawater, sea cucumbers can be easily fixed on the seabed or rocks, so the suction cups are more slender and long.

3. Look at the body

Wild sea cucumbers grow in the deep sea, usually the sea water will be as deep as 26 to 27 meters, there is no fixed bait, at least three or five years to grow, so that long-term life in the deep sea, coupled with the accumulation of more sun sunshine time, the color of sea cucumbers will become dark gray, the flesh is thicker and the skin is thinner. Captive sea cucumbers, need to be fed regularly and quantitatively bait, most of them can grow into a ** body shape in one or two years, the color is mostly dark yellow, bright, thick skin and thin meat.

Sea cucumbers grown in the wild are usually intact in appearance and their rinds are not scratched. Most captive sea cucumbers have scratches on the outside. This is because when fishing sea cucumbers, most of the sea cucumbers in the deep sea are on rocks or in hanging nets, which are easy to fish.

Most of the captive sea cucumbers lie in the cracks of solid rocks, which are not easy to catch, and they must be obtained with special tools and quick shoveling, which is easy to hurt.

4. Hair on the taste

Wild sea cucumber is very resistant to cooking, after cooking, the ginseng body is elastic, the thorns are clear, the flesh is tendonous, there is a bite head, and the taste is good; Captive sea cucumber is not resistant to cooking, and it will become naan after cooking for a long time, and the meat lacks toughness and has a bad taste.
