Abalone Summer Technology
Recently, more than 500,000 abalone seedlings from Dongshan, Fujian Province were “camped†in the abalone pond of a fisherman's home in a development zone in Qingdao for a three- to four-month “holidayâ€. This summer, a total of nearly ten million abalone from Fujian province “heated up†in Qingdao. Fisheries experts said that the “South Bao Bei Bei Yang†and “North Bao Nan Yang†breeding methods not only improved the survival rate of abalone, but also helped save company costs.

It is understood that abalone on the breeding water temperature requirements are very high, and its suitable growth temperature is about 20 °C. In the summer, the southern species such as Black abalone and Haliotis discus hannai, which are introduced into the south, will die due to excessively high water temperatures. At this time, water temperatures in northern sea areas such as Qingdao are suitable for abalone growth. In recent years, as summer arrives, many farmers in Fujian have sent abalone seedlings and abalone that are close to the finished product to Shandong and other places for breeding, and then took the abalone back in November of that year. According to industry estimates, at least 10 million southern abalones will “vacate†in Qingdao this summer. "This winter, we also need to send abalone to Fujian for the winter!" The manager of Qingdao Jinyu Ocean Technology Co., Ltd. told the author that although abalone farming in Qingdao is at the forefront of the country, it also faces the problem of wintering abalone.
Will you send your abalone thousands of miles to another place for breeding, but can you make a profit? According to Mr. Lin, a farmer in Dongshan, Fujian Province, the timely delivery of abalone to the North will result in a significant reduction in the mortality rate. After deducting freight and related expenses, he will still make a lot of money. The manager of Qingdao Jinye Marine Technology Co., Ltd. calculated the account: In winter each year, the company's cost for seawater heating to help abalone winter reaches millions. If it is transported to the south for farming, the freight and sea area lease fee is only 200,000 to 300,000 yuan. Only this one will save a lot of money.
In this regard, Zhang Xiufeng, a senior engineer of the Qingdao Fisheries Technology Promotion Station, said that the "Northern Baonan raising" and "South Baobei raising" farming methods have certain scientific principles. In winter, abalone is sent to the south to raise the output of finished abalone, and “overwintering fees†are also saved. Another expert said that overseas abalones have come to Qingdao to “summer†and have also increased Qingdao’s fishing revenue.
Abalone transport adopts dry transport and wet transport. Generally dry transport is adopted for short-path and short-term use, and wet use is adopted for long-distance and long-distance use. Plastic plates are used as attachment base for abalone, and rigid containers for cleaning and disinfecting are placed for transport. Among them, the abalone that is being transported should be selected for temporary maintenance in order to increase the survival rate of transportation.
Abalone transportation plans and arrangements should be carefully studied. The dry transportation method should be reasonable in density, not squeezed each other, ensure high humidity, low temperature, regular watering, prevent direct sunlight and rain, and be placed in a cool and ventilated place, transported to the destination regularly. The wet transport method pumps must ensure normal operation, have sufficient seawater, density and sparse, non-overlap, large water flow, small temperature difference, and promptly involve the removal of fecal debris, if the transport time is too long, a small amount of feed should be cast.
After the abalone is transported to the destination, it must be raised for a period of time so that it can be rejuvenated before it can be removed from the stockpile. The abalone can be used to reduce the water temperature. Ultraviolet sterilization or drug treatment.
The young bait must be baited, and the quality of the bait is directly related to the growth rate of the abalone. Generally about 3 mm abalone can not eat large algae, mainly rely on the attachment of diatoms as food, do not feed at this time; grow to 5-6 mm, began to eat delicate alfalfa and other algae. As the individual grows, it turns mainly to large seaweeds.
The natural sea area and the number and quantity of bait for feeding depend on the season. The water temperature is high in summer, the seaweed is perishable, the decay of the fronds sinks to the bottom, the ammonia nitrogen in the water increases, the dissolved oxygen decreases, and the culture environment is easily deteriorated, affecting the normal abalone. Activity, so at this time every 2-3 days feeding once, the amount of investment should be less, to be able to finish the prevail. Autumn is the season in which abalone grows faster. It needs to feed enough fresh bait and feed it every 4-5 days. In winter, when the water temperature is low, abalone eats less, and fresh algae do not rot in the water for 7-8 days. Therefore, it is recommended to feed once every 8-10 days in winter. Note that each feeding should be done after removing the bait residue and abalone's excrement and replacing the fresh seawater.
The abalone hi dried young seaweed, in the absence of fresh seaweed, can be used as bait after soaking in dry algae, and the algae feeding is good for mixing, in the algae, wakame, kimchi, kelp, horsetail, etc. It is a kind of seaweed that abalone prefers to eat. The effect of the bait is good and the growth speed is fast. The seaweed, which is rich in local resources, has been shown to be less than ideal and has a great influence on abalone digestion.
Abalone farming can also be fed with artificial diets. When using it, it should be considered that it contains animal protein, soaked in water, perishable, so the time to grasp the baits is correspondingly shortened.
The feeding of abalone for industrial planting or abalone breeding in the pit is basically the same as the above. The difference is that the factory culture or the water temperature and the room temperature of the tunnel are relatively constant, so there are differences in feeding time.
