If you want to learn how to farm sea cucumbers, what are your suggestions? 20

If you want to learn breeding, it is best to consult experienced teachers directly (that is, farmers who will raise), and now sea cucumber seedlings are so expensive, no one can afford to pay for them.

Originally, I wanted to give you information about the Fisheries Academy, but it is better to have a theory than a practical point, so go to the sea cucumber farm and start from a low level

Check it out.

Many people want to farm sea cucumbers, what is the prospect of cultivating sea cucumbers now? Sea cucumber is an echinoderm and one of the eight treasures of seafood, which is rich in nutrients. Sea cucumber is one of the most important edible sea cucumbers in northern China, suitable for growing in the northern coastal areas of Liaoning, Hebei, Shandong, Jiangsu and other provinces.

With the improvement of people's living standards and the reduction of natural growth of sea cucumbers, the yield of wild sea cucumbers has been difficult to meet people's needs. Sea cucumbers are cheaper on the coast and more expensive in the mainland, basically depending on your area is not suitable for breeding, the profit margin of raising it is very considerable, and it is now"The prospects for the next three years are good, due to the high temperature in Liaoning this year, captive sea cucumbers are about the same, so the **** is better, last year's 3 to 7 sea cucumbers received at a price of 40-50 yuan, and this year's ** has more than doubled.

Sea cucumbers can be raised, but the nutritional value of the raised sea cucumbers is relatively lacking, but many people still choose artificial breeding because of considerable profits. Sea cucumbers have strict requirements for water quality. Site selection, construction and sanitary conditions.

Aquaculture sites should be in line with the local fishery administrative departments to develop the tidal flat aquaculture plan. For the construction of breeding ponds, according to different breeding species, modes and conditions and other factors, scientifically and reasonably determine the size, form and scale of breeding ponds. In terms of inlet and drainage channels, it is required that the inlet and drainage outlets should be as far away as possible, and the inlet and drainage channels should be set independently, and the new farms shall not be close to the inlet and drainage outlets of existing farms.

Before breeding, seawater should be used to remove the dirt and debris in the breeding pond, and do a good job in the maintenance of the pond and the inlet and outlet channels. When choosing a cement pond as a breeding pond, it must be rinsed repeatedly. When choosing a pond as a breeding pond, the place where the sediment is thicker must be dredged and exposed to the sun to promote the decomposition of organic matter.

Deceased instances are to be moved to land as soon as possible and destroyed.

Sea cucumbers are suitable for living in sea areas with clear water quality, stable tide levels and abundant baits, and can also survive in sea areas with temporary large waves and turbid water quality. For the water temperature requirements, it can survive in -3 -34, the optimal temperature is 12 -18, more than 20 will enter the dormant state, and below 5 will stop growing. The salinity requirement is between 18-33.

In terms of sediments, harder sediments are suitable for the growth of Japanese totoaba and better places with abundant rocks, reefs, aquatic plants, and seaweed.

It is necessary to have a very reasonable site, and it must also be scientifically put into operation, and there must be reasonable feeding and management. In the process of growth, it is also necessary to prevent and control diseases in a timely manner, and master these skills and key points, not only can you have a very healthy sea cucumber, but also have good development prospects, and will also have good benefits.

When breeding, we must pay attention to the temperature of the water and the sanitation of the surrounding environment, so that it is very convenient to use, and there must be corresponding water resources around, so as to ensure that some water outages can be avoided.

1.Artificial reefs and reefs are also an indispensable condition in the cultivation of sea cucumbers, and most of us use artificial reefs. The reef is mainly a place for sea cucumbers to rest, recreation, life and feeding.

2.Hydrological conditions, first of all, we need to choose the estuary or estuary far away from pollution, and secondly, the ammonia nitrogen content in the seawater is low, the salinity in the seawater is about 25 to 35, and the dissolved oxygen in the water should reach more than 5 milligrams of liters. 3.

Topography and substrate, the topography and substrate of the farm are also very important. Generally speaking, sea cucumber farms will not be selected in places with strong wind and waves, and the best ones are relatively gentle inner bays and coasts, such as rocky reef coasts, low-lying saline-alkali land, and intertidal zones are excellent breeding sites.

First of all, the water quality requirements are particularly high, try to choose the area close to the sea, and secondly, reasonably control the stocking density. It is best to choose spring and autumn for sheep grazing, but also for disease prevention and disinfection of medicines.

It is suitable for living in sea areas with clear water quality, smooth currents and abundant baits, and can also survive in sea areas where the water is temporarily strong and the water quality is turbid. The water temperature requirement is to survive in -3 and 34, the optimal temperature is 12--18, when it exceeds 20, it will enter the summer hibernation state, and if it is lower than 5, it will stop growing. The salinity requirement is between 18 and 33, and for the substrate, the harder sediment substrate is suitable for the growth of sea cucumber, and it is better in areas rich in rocks, reefs, aquatic weeds and seaweeds.

Many people want to farm sea cucumbers, but what are the prospects for cultivating sea cucumbers now? When you buy a pound of sea cucumber, eight taels are salt, and two taels are sea cucumbers, and this industry is also quite hard. Later, I went to some places to observe, and the sea cucumber industry, adulterated and fake, has reached a very serious point.

All of them were conducted after the incident, and all the parties interviewed were practitioners in the sea cucumber breeding industry, and the sea cucumber industry was their livelihood. With a guarded investigation and evidence collection, I don't know if the final result is 100% credible.

As long as there are enough profits, the capitalists behind these will dare to ignore any risks, not to mention that the cost of crime in our country is relatively low, so it is inevitable that something will happen, and it is strange if nothing happens. Flip until you can accept it. In the past, there was a kind of inspection, called a surprise inspection, and now there is an inspection, called a notification inspection, maybe things are not as bad as we imagined, maybe there are only a few black-hearted businesses, but they are full of collisions with reporters.

In order to maximize the benefits, dichlorvos plays a very big role, effectively removing weeds, insects, fish, and the rest are sea cucumbers! This can be effective growth, of course, this destroys the ecological environment, for the sake of personal interests, it is indeed unscrupulous. Especially in important wine venues, without sea cucumbers, the face will be lost.

Ask someone to do something, let alone do it. Carrying two boxes of sea cucumbers, it looks magnificent. This kind of blessing is not something that ordinary people can have.

Such a terrifying truth was known to the dignitaries.

The resources that humans obtain from the ocean are contaminated with toxicity, marine plants, marine minerals, and marine fish are all affected, and eventually the toxicity of dichlorvos will be reflected on humans. Headache, nausea and vomiting, abdominal pain, diarrhea, drooling, miosopia, blurred vision, profuse sweating, dyspnea and other symptoms can cause death within 10 minutes once taken orally in large doses. Therefore, it cannot be used at will, let alone taken by mistake.

Yes. The Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, for many years, has conducted a follow-up comparative analysis of wild sea cucumber culture, and the results show that the difference between wild sea cucumber culture in the main component collagen content and amino acid content is not very obvious, and the protein content of farmed sea cucumber is usually slightly higher than that of wild sea cucumber, and the amino acid content is slightly lower than that of wild sea cucumber, and the difference is usually about 1%. <

Yes.

The comparative analysis of data over the years found that the sea cucumbers cultivated in the environment under strict control of the standards of wild sea cucumbers had higher nutritional value, and the nutritional value of cultivated sea cucumbers was slightly lower than that of wild sea cucumbers. The main reason for this difference is that the preparation of bait and its growth environment for cultured sea cucumbers need to be further optimized.

1. Shrimp pond farming mode: shrimp pond aquaculture is suitable for small and medium-sized aquaculture scale, it uses the existing shrimp pond to put stones and tiles to artificially simulate the reef for sea cucumbers to inhabit, and the density is 3000-5000 sea cucumber seedlings per mu.

Sea cucumbers feed mainly on algae and organic detritus, and are fed with algae such as kelp and wakame with bait when artificially fed. The water level of the shrimp pond is kept between meters, but when the temperature is high in summer and low temperature in winter, the water level should be increased appropriately to make the sea cucumber safely survive summer and winter, and water quality management should be strengthened during breeding.

2. Sea raft farming mode: choose to breed in the unobstructed sea area where the tide is smooth, there is no major wind and wave invasion, and the unpolluted sea area is generally cultivated, and the abalone polyculture mode is generally adopted, and the net cage and plastic barrel are used to hang the water layer for aquaculture, and the breeding density is reasonable. The feeding bait is also artificial bait and algae such as kelp, and as the sea cucumber grows larger, the breeding density is evacuated, and the cages are checked regularly to prevent absconding.

3. Submarine cage breeding mode: choose an inland sea bend without strong wind and waves, smooth tide and no large amount of fresh water injection to breed, make a net cage with steel bars, place stones and other objects in it, simulate the reef, and then cover the net coat outside the cage. The breeding density is 200 seedlings per square meter, artificial bait and kelp algae are fed, and the growth is checked regularly to determine the breeding density, as well as to check the damage of the net coat and repair it in time.

4. Intertidal zone stone breeding mode: the intertidal zone stone breeding mode is to use the intertidal zone according to the topography characteristics, with reinforced concrete to build a dam, the dam stone to raise ginseng, the height of the dam should be determined according to the tide level, and there should be drainage holes in the dam to facilitate natural drainage. It is also fed with artificial bait and kelp and other algae, and the breeding density is about 10,000 seedlings of about 5cm per mu.

5. Factory abalone and cucumber polyculture mode: factory abalone cucumber is a large-scale artificial breeding method, which is polyculture with abalone through the factory workshop, and the breeding density is within 100 seedlings per square meter, and the seedlings are stocked according to the situation. During breeding, the growth environment of sea cucumbers is simulated by artificial means, such as reducing the water temperature in summer and increasing the water temperature in winter, so that the sea cucumber does not go through summer hibernation and hibernation, shortens the growth cycle and improves profits.

Sea Cucumber Farming Technology:

1. Build a ginseng pond.

In the mid-tidal or low-tide zone, it is advisable to take advantage of the geographical advantages, preferably with a rocky reef bottom, with concrete and stone to enclose ponds of different sizes, and to thicken and strengthen the walls of windy sea areas. When the tide is small, it is necessary to ensure that the water storage is not less than the meter, and there is no leakage. The selected sea area shall not be polluted, especially oil pollution, the breeding pond shall leave an inlet and drainage gate, the replacement of the seawater in the pool is best to rely on the natural tide, the daily water exchange is not bottom to about 30%, and the average water depth in the pool is more than one meter.

2. Put artificial sea cucumber reefs.

The purpose of building an artificial sea cucumber reef is to provide a shelter for sea cucumbers and to propagate a large number of seaweeds and aquatic plants for sea cucumbers to inhabit, feed and hibernat. Artificial sea cucumber reefs can be made of tiles, bricks, discarded scallop cages, and even slightly larger rocks of different shapes. The placement of the reef is based on the principle of increasing the hidden space of the sea cucumber as much as possible, which can be placed in a row or in a pile, and the more the number of reefs put into the reef according to the actual conditions, the better.

3. Transportation of ginseng seedlings.

Ginseng seedlings are usually transported by wet and dry methods. The so-called wet transportation is to put the ginseng seedlings in a canvas bucket when transporting ginseng seedlings, each barrel contains about 300 ginseng seedlings, and the water cube is about about 100 heads. The so-called dry transportation is to put the ginseng seedlings in a plastic turnover box, the bottom of the box is laid with 2cm thick absorbent cotton, and two layers of gauze are laid on it, soaked with seawater, and the ginseng seedlings are evenly placed flat, and the periphery is blocked by plastic sheeting.

When the weather is dry and hot, it is necessary to spray seawater appropriately on the way.

4. Putting ginseng seedlings.

The density of ginseng seedlings can be reasonably controlled according to the specifications of ginseng seedlings, according to the principle of small seedlings and more seedlings to adjust, usually 300-500 kg size of seedlings can be controlled in 10-30 square meters, and the final survival rate can reach about 35%. In addition to the water temperature and water quality, the stocking density of ginseng seedlings is also related to feeding management, and reasonable feeding of sea cucumber compound feed with good quality can effectively improve the survival rate and shorten the breeding cycle.

5. Bait feeding.

Soak the sea cucumber with feed in water for 10-15 minutes, and then evenly sprinkle it on the ginseng reef and its vicinity, the feeding amount can be 3-5% of the total weight of the sea cucumber in the pool, generally once a day in the morning and evening, or the next day to feed, pay attention to do not drain the water when feeding every day, so as not to waste the loss of feed, 7-9 months generally do not feed.

6. Harvest of sea cucumbers.

Sea cucumber weight generally reaches more than 250 grams can be harvested, harvest time can be flexibly mastered according to the market ** and breeding cycle, generally late autumn and early winter harvest more, harvesting methods are mainly based on diving capture, conditional can drain the pool water for sorting.

The temperature and salinity of sea cucumbers are optimally cultivated indoors.

Bottom sowing, greenhouses, and cages.
