Yantai abalone, Yantai special seafood, geographical indication products, one of the "sea fish eight treasures", known as "the crown of seafood." The sea water in Yantai is clear, the water is rushing, the seaweed is clustered, and the rocky reefs are provided. It provides abundant bait and good growth space for the survival of abalone. Therefore, the abalone produced here has the characteristics of tender meat, fresh but not greasy, nutritious, clear and rich. Whether it is cooking or broth, it is delicious and wonderful. Su Shi once wrote a long poem "Squid Row" during the Dengzhou period. It is said that the beauty of Yantai Abalone and Haiyan: "The gradual squad is shot by the long squid, and the first squid is not recognized. The sage of the sage is empty, and it is willing to kiss the Beihe pro. Feeding the food. The middle tyrants are separated by a beam, one is a thousand gold straight. A hundred years of north and south 鲑 通 通, often wrecked and smashed. East with the sea snail snail, the exotic treasures come more.胾 蚌 蚌 蚌 君 君 君 君 君 君 君 君 君 君 君 君 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬 蓬For squid. In his poems, Su Shi described and fascinated the deliciousness of the squid and the historical anecdotes. The whole poem has seven sentences and thirty-six sentences, and the descriptions are many: The first is to write the story of Wang Hao and Cao Cao eating abalone, which leads to the two males eating abalone, which leads to their own thoughts about the sorrowfulness of the predecessors to take the abalone smell; Because of the inconvenience of transportation away from the mainland and the traffic barrier, the abalone produced by Long Island is very expensive, “valued in gold”, which leads to the hunger and trafficking of outsiders; the third is the origin of abalone and the abalone season and thrilling scene. It tells people that the harvesting of abalone not only has the limitation of season and enemy time, but also the collection method is extremely complicated and difficult. The fourth is to write the deliciousness and value of Long Island abalone, including processing, production, collection and other methods. The abalone is a friend, expressing deep friendship; finally writing abalone eye-catching, in preparation for the old man to read. "Send the coffin for the eyes, but take the fine book to prevent the old." At that time, Su Dongpo, who had just finished the life of the eunuch in Huangzhou for five years, came to Dengzhou to eat such seafood, and he was delighted by the food. Why Yantai abalone is delicious, because the Yantai sea area is suitable for abalone survival. There are a lot of reef areas with clear sea water, deep water flow, high salinity and abundant seaweed. The abalone is most favored on the reef gravel of several meters to several tens of meters, especially the abalone that grows in the Changdao area of ​​Yantai. Because it lives in relatively low temperature seas all the year round, the growth period is relatively long, and the impact of seawater is appropriate. Rich, its vitality and nutrition far exceed other varieties of abalone. Throughout the dynasties, Dengzhou officials gave the abalone as a tribute to the emperor and was listed as a royal meal. After the Qing Dynasty, there was a sea Bazhen, and the abalone was hailed as the crown of the sea. There are many kinds of dishes cooked by abalone, such as "boiled abalone" and "bamboo abalone", but in the Yantai area, locals prefer the original fresh steamed abalone, which is delicious.

Quality technical requirements for Yantai abalone (1) Increase the environment of the cultured sea area. Located in the shallow sea area between 119°34' to 121°57' east longitude and 36°16' to 38°23' north latitude, 15 meters isobath, the bottom of the sea area is natural rock reef, the cave has caves, cracks, brown algae, The green algae is rich in resources, the water flows smoothly, and the water quality is clear; the current is mainly tidal current, mostly reciprocating along the coast, the flow rate is 20 cm/s to 50 cm/s; the annual temperature change is -1.0 °C to 28 °C, and there is little icing in winter. The average seawater salinity is 28‰ to 32‰; the pH is 7.8 to 8.2. (2) Production process. 1. Breeding abalone: ​​(1) Choosing abalone: ​​Selecting 3 to 4 years old individuals with full soft body and strong vitality without damage, the shell length is 7cm to 10cm. (2) Pro-boiling: The density of cultivation is 20/m3 to 30/m3, and the ratio of male to female is 5:1. After the pro-bow enters the pool, the water temperature in the pool is the same as that in the first 3 days, and then gradually warms up, 2 °C/d in the early stage, 1 °C/d in the later stage, and then raised to 20 °C to promote the ripening. When the effective accumulated temperature reaches 700 °C·d to 900 °C·d, the gonads mature and can induce spawning. Use fresh seaweed or wakame as bait and feed once a night. The daily feeding amount is 20% to 30% of the weight of the pro-bow, and the whole amount of water is changed once a day, and the number of suctions is appropriately increased later. Continuously inflated, 300L/m3·h. The illumination is less than 500 lux. 2. Larval cultivation: (1) Egg collection: UV-irradiated seawater or hydrogen peroxide seawater immersion method induces egg collection with a density of 50/ml to 70/ml. (2) Incubation: density is 15 / ml to 20 / ml, water temperature is 20 ° C to 22 ° C. After adding the semen for 10 minutes, the eggs should be washed in clean sea water and washed 5 times to 8 times. (3) Incubation: the density is 5/ml to 10/ml, and the water temperature is changed from 18 ° C to 20 ° C three times a day, each time changing 70%. Continuous micro-inflating, the illumination is below 500 lux. When the seedlings have head tentacles and balance capsules, the seedlings are placed. Gradually increase the amount of inflation, each time change water 1/2. 3. Breeding of juvenile abalone: ​​(1) Miao seedling: When the juvenile abalone shell is more than 5 mm long, it is peeled off from the seedling board and moved to the corrugated board. In the range of 4000 / m2 to 5000 / m2. (2) Management: The daily water flow is 5 to 8 times that of the breeding water body, and the light is 1000 lux to 4000 lux. When the water temperature is below 15 °C, the bottom of the pool is cleared once every 4 days to 5 days; when the temperature is 15 °C to 20 °C, the bottom of the pool is cleared every 3 days; when the temperature is above 20 °C, the bottom of the pool is cleared once every 2 days. . Continuously inflating a large amount of gas with a diffuse stone. The bait is mainly artificially mixed with bait, supplemented by natural bait. The daily feeding amount is 5% to 7% of the weight of the juvenile abalone, and the bait is fed once a night. The density of cultivation should be sparse in time as the individual increases. 4. Abalone cultivation: (1) Bottom broadcast proliferation: 1 bottom broadcast: select the appropriate sea area, from early May to mid-October, the water temperature is above 8 °C, and the diver dive to spread. Juvenile abalone shell length u0026gt; 3cm, density of 2 / m2 to 3 / m2. 2 Management: Algae proliferation in areas where algae grow sparsely. Clear starfish and other enemy creatures. Regularly and regularly conduct tracking and monitoring, and master the distribution, density, growth rate, survival, etc. of abalone, and determine the water temperature. 3 Harvesting specifications: When the abalone shell reaches 7cm or more, it can be harvested. (2) Clam culture: 1 Condition: Select a cultured sea area with deep water, smooth, abundant algae and little change in salinity. The distance between the rafts is 5m to 15m and the distance between the hoists is 2.0m to 2.5m. The grower mainly adopts a multi-layer cylindrical cage with a cage diameter of 60 cm, and the layer spacing is 12m to 15cm, and each layer is 6 to 12 layers. Young bumblers from 2 cm to 3 cm are stocked from 100/layer to 120/layer. The water layer is placed between 5m and 10m. 2 Management: The bait is fed with seaweed such as kelp and wakame, and it can also be fed with high-quality flakes and bait. The residual bait must be recycled to the shore, and the enemy organisms and attachments should be removed in time. The aquaculture water layer should be adjusted in time according to the growth of the abalone and the wind and waves. When the cage is operated, try to avoid the peak period of the attachment of mussels, barnacles and oysters. 3 Harvesting specifications: When the abalone shell reaches 6cm or more, it can be harvested. It is strictly forbidden to label “wild” for abalone cultured abalone. 5. Environmental and safety requirements: The prevention and control of the breeding environment and epidemic diseases must comply with relevant national regulations and must not pollute the environment. (3) Quality characteristics. 1. Sensory characteristics: Types of senses Special color Wild, aquaculture abalone abalone shells are complete, brown, no attachments, silvery white in the shell, pearls and other luster, fleshy yellow color, elastic, no odor. The abalone shell of the abalone is intact, emerald green, with no attachments. The shell is silvery white, pearly and other luster. The meat is light yellow, elastic and odorless. 2. Physical and chemical indicators: protein ≥ 13%, glutamic acid ≥ 4.5%, fat between 0.25% and 0.4%, carbohydrates between 3% and 4%. 3. Safety requirements: Product safety indicators must meet the relevant regulations of the state for similar products.
