CATDOLL : CATDOLL: How long is the growth cycle of sea cucumbers?

1. How long is the growth cycle of sea cucumbers?

The growth cycle of sea cucumbers depends on the species. Most of the sea cucumbers on the market are farmed sea cucumbers. The best sea cucumbers in China are bottom-sown sea cucumbers. The farmed sea cucumbers we often see have a growth cycle of about one to two years, while bottom-sown sea cucumbers take two to three years to grow. The last type is the wild sea cucumbers we often hear about. Wild sea cucumbers are basically hard to find in my country now. Even if you see them, you will be discouraged by the price. Wild sea cucumbers need to find food by themselves and guard against the invasion of natural enemies, so it usually takes three to five years to reach the nutritional standard.

Another: Identification method of dried sea cucumber:

1. Look at the color, whether it is black or not. Good sea cucumbers should be gray-brown or dark brown, with a shiny surface and gray or white intestines. Low-quality sea cucumbers mixed with sugar are dark black, with a very dark color, and the intestines will turn red or black.

2. Look at the shape and pinch it. A good sea cucumber has a well-proportioned body, firm meat, sharp and complete spines, feels hard and is not easy to bend. Sea cucumbers mixed with sugar are just the opposite, with bodies that are easy to bend but spines that are straight.

3. Heat it up and bend it. Sugar dissolves easily. When buying sea cucumbers, you can try to heat them up. The simplest method is to rub your hands to warm them up, then hold the sea cucumber in your hands for a while. When it is warm, hold the two ends of the sea cucumber and bend it. If you find that the sea cucumber becomes bent and soft, and the higher the temperature, the more obvious this change is, it means that sugar has been added.

The above is my answer to this question. If you find it helpful, please accept it. Thank you.

In order to make sea cucumbers grow quickly, sea cucumber farmers usually feed them growth hormones, antibiotics and other hormones, so that sea cucumbers of 3-5 months old can grow to the size of sea cucumbers of 3-5 years old. This is why you see sea cucumbers of 3-5 months old, and they will tell you that they are mature sea cucumbers. In fact, they are the same species, the difference is that one is wild and the other is farmed.

2. The cycle of sea cucumber culture in cofferdams

The cycle of sea cucumber farming in Weishu Luyan is about 5 years. Because the farming time of sea cucumbers is short, the quality of sea cucumbers is not good, the sea cucumbers do not grow large, and the economic benefits are not good. Sea cucumbers farmed for 5 years are sold as commercial sea cucumbers, which have good economic benefits.

The cycle of sea cucumber culture in cofferdams is generally divided into 7-8 months, of which the first two months are the initial breeding stage, 3-5 months are the sea cucumber maturity period, 6-7 months are the breeding period, and 7-8 months are the harvest period.

3. Is there any relationship between the growth age of sea cucumbers and their nutritional value?

Regarding the age of sea cucumbers, many ginseng lovers are often misled by merchants, who often say that sea cucumbers are 6, 7, or 8 years old. At the same time, merchants will also tell ginseng lovers that the growth years of sea cucumbers are directly related to their nutritional value. The longer the growth period of the sea cucumber, the higher the accumulated nutrition, and the correspondingly more expensive the price.

At this time, we must first consider whether the merchant said that there is water. The nutrition of sea cucumbers is indeed related to the growth period. From the perspective of the growth cycle of sea cucumbers, it takes about 3 years for ordinary sea cucumbers to mature, but the sea cucumbers raised under artificial greenhouses and other conditions have a shorter maturity period and can be caught in about 1-2 years. The maturity period of sea cucumbers in Fujian is also relatively short. Purely artificially cultivated sea cucumbers grow fast and are mainly fed with feed, so the nutritional accumulation is relatively small.

Generally speaking, wild sea cucumbers become "mature sea cucumbers" that can be caught when they grow to about 3 years old. Although the size of the sea cucumbers changes slowly after this time, the nutrients in their bodies are constantly accumulating, especially naturally grown sea cucumbers, which continuously convert external food into their own nutrients. Therefore, the older the sea cucumbers are, the thicker the meat, the higher the nutritional value, and naturally the more expensive they are.

Now I will tell you how to correctly judge the age of sea cucumbers:

1. To judge the age of sea cucumbers, we must first look at the living environment and lifestyle of the sea cucumbers, that is, to determine whether the sea cucumbers are wild or farmed. It is unscientific to directly judge the age of sea cucumbers by looking at their size.

2. The age of wild sea cucumbers can only be judged based on our many years of industry experience and the size of the sea cucumbers. No one can tell exactly when and how many years, months, and days they were harvested.

3. For farmed sea cucumbers, the decision should be made based on the farming method and industry experience. For example, farmed sea cucumbers in the south can be put on the market in just half a year, while captive sea cucumbers generally take about 1-3 years.

It should be emphasized that it is not absolute that the older the sea cucumber, the more nutritious it is, because the growth period of sea cucumbers is about 10-12 years. Sea cucumbers that exceed this period will generally "die naturally" and will not continue to grow. Therefore, when purchasing sea cucumbers, ginseng lovers must not only listen to one-sided opinions.
