The squid is a group of ancient cartilage fish in Heilongjiang. It has been a breeding history of 200 million years since the Jurassic period. It is a second-class protected animal of the world's endangered extinct species and is known as the "living fossil". The squid, as a famous product of Heilongjiang, can weigh up to a few hundred kilograms to a thousand kilograms and enjoy the reputation of “Freshwater Fish King”. This fish has a delicious taste, crisp and fragrant bones, and there is almost no waste in the whole body. The stomach, lips, bones, clams and seeds are the best raw materials for cooking famous dishes. Caviar, also known as caviar, marinated products such as salmon eggs and salmon eggs. In Persian, it means fish eggs. Strictly speaking, only salmon eggs can be called caviar, and the quality of caviar produced in the Caspian Sea bordering Iran and Russia is better. Geographical environment Fuyuan County is located on the east and north sides of Russia and across the Heilongjiang River and Wusuli River. It is adjacent to the Rao River in the south and the Tongjiang River in the west. The Heilongjiang River and the Wusuli River are not only the Sino-Russian border river, but also an important water area for natural fisheries in northern China. The special squid here is a regional migratory fish. It has been used for large-scale migratory activities in the river section of Fuyuan County of Heilongjiang Province (less frequently in the Wusuli River). It is recommended to bait in the sedimentary gravel section of the river. The swims are wintering in the deep waters of the river. The juveniles are thawed into the shallow waters in the spring, and the adult fishes begin to spawn in May and June each year. The river water temperature reaches 16~18 °C and enters the spawning ground to start spawning. Fuyuan County is a mid-temperate continental monsoon climate. The spring wind is dry, the summer is hot and rainy, the autumn is high and the weather is cold and dry. With an average annual temperature of 2.2 °C, the natural environment is beautiful and the water resources are vast. It is a natural fishery and provides an excellent natural environment for the growth of carp. Cultural background The origin of the name of the carp was in the Qianlong period, and the Hezhe people of the scorpion captured a weird big fish. At that time, no one had ever seen such a big fish, and was very surprised. According to the custom of the time, all the rare and precious items were sent to the capital for the emperor. Therefore, this "great monster" was experienced by the local fishermen from the border of Heilongjiang in the motherland. In the case, it was sent to the capital. At that time, the civil and military officials could not name the big fish. No one had seen it. According to the results of the inspection, the fish was not only non-toxic but also delicious. So the imperial dining room quickly made a delicious piece of fish, please taste the Emperor Qianlong, and the Emperor Qianlong tasted it. He suddenly said that he was happy and delicious. The eyes are small and small, the scales are huge and repaired, the nose is like a scorpion, and the head is like a pocket.” This means that the big fish has a very small eye, the slender body has no scales, and the nose is like an ancient weapon. , head helmet. The ministers next to the emperor read the poem written by the emperor and immediately praised: "Write well, write well." At this time, I don’t know which minister said that since you wrote the poem to the big fish, why not give it What about the name? All the ministers greeted the emperor and asked the emperor to give the name to the big fish. At this time, Qianlong thought about it and said: "This big fish is the largest fish in the freshwater fish that is currently found. It can be called the 'fish king'. From now on, it is used as a royal tribute. Every year, it is a tribute to the royal family. The big fish king of the tribute is called 'squid'." Look! The word "鳇" on the side of the "squid" is next to the fish word, and on the other hand is the emperor's emperor. This is the origin of the name "squid". Since then, this story has been passed down to this day. Brand building and development of fishery resources One side of the strong fishing industry is to raise one person. There are 56 large and small rivers in Heyuan River and Wusuli River in Fuyuan County, and there are more than 200 large and small lakes. It is the most complete and most productive area in Northeast China. In the 1980s, fisheries served as the pillar industry of Fuyuan, and its income has always occupied half of the financial sector. Sometimes, fishermen can catch 1,000 kilograms when they fish a net. They have set a record of 2,538 tons of catches per year. The "sticky squid" is a true portrayal here. However, after the 1990s, the fishing intensity continued to increase, coupled with the pollution of the Songhua River and Heilongjiang Rivers, the fishery resources of Fuyuan were exhausted, the catching volume decreased year by year, and the fishery economy was on the verge of collapse. In 2002, the Fuyuan fishery changed to “only catching and not raising” in the past as “mainly supporting, catching and combining”, and a breeding team consisting of scientific researchers, soil experts and breeding workers came into being. Hard work pays off, the birth of the first artificially cultivated carp fry has changed the situation of Fuyuan fishery. In 2004, a 55,000-square-meter squid breeding base consisting of a breeding workshop, a cultivating workshop, a deep processing workshop and a fish exhibition hall was completed, and Fuyuan became the largest special breeding base in the province. The squid fertilized eggs and fry are exported to Beijing, Guangdong, Fujian, Jiangsu, Hebei and other places. Fuyuan County provides squid fertilized eggs and juveniles that account for more than 90% of the country's total. The annual sales income exceeds 65 million yuan. The largest net cage breeding base in the country was built in the Dajia Lake of Fuyuan County. There are 2,000 cages and the water surface has been developed to 60,000 square meters. The base also timely combined its technological advantages with the natural conditions and climate advantages, and established three famous special fish breeding bases in Daqing, Dandong and Hubei, and set up more than 40 waters in large cities such as Beijing, Shanghai and Hangzhou.

Fuyuan "Heilongjiang carp" caviar quality technical requirements (a) fishing area. Fuyuan County has jurisdiction over the Heilongjiang carp and squid fishing waters within the administrative area. (2) Seedling cultivation and release. Among the broodstocks that have been harvested, artificially propagated without injury or well-developed. The larvae with a length of 1.5 cm are hatched by techniques such as oxytocin, laparotomy, artificial insemination, de-sticking, and water-incubation. The larvae are bred in water. First cultivated with water simmer for 10 days, then domesticated and fed artificial feed. After feeding 50 to 60 days of artificial feed, 10 to 15 cm of large-sized fingerlings are bred, released, and proliferated, with an annual discharge rate of 1.5 to 2 million. (3) Source of raw materials. The fish eggs of the caviar are taken from the gonads harvested in the protected area to the ovary of the broodstock of Heilongjiang carp and Heilongjiang carp in the middle of IV. (4) Processing technology. 1. Disposal of broodstock: Heilongjiang carp and carp broodstock that process caviar must be fresh fish. After the fishing, the broodstock that have not been injured or injured can be transported to the refrigerating workshop of the caviar processing factory by live fish cart, and the live fish is taken by caesarean section. The broodstock caught by the fish can not survive. It is immediately cut off from the brachial artery and stored in a refrigerated truck (2 to 4 °C). It is transported to the refrigerating workshop of the caviar processing plant within 6 hours. 2. Egg retrieval: in the cold storage workshop of the caviar processing plant, the workshop temperature is 2 to 4 °C. The broodstock that took the eggs was first washed with water, then the fish was sterilized with 5% saline and then the eggs were taken by laparotomy. 3. Washing eggs and separating: After each fish is taken, immediately wash the blood in ice water at 0 to 1 °C and drain the water. 4. Fresh water preservation: The dried egg is placed in a fresh-keeping tank, stirred with saturated saline for 15 to 20 minutes, and filtered to dryness. 5. Salt preservation: Different grades of carp and carp are stored separately. Eggs after fresh-keeping treatment are stored in wooden barrels of the same grade. Sprinkle 3 to 5 cm of granular salt on the eggs, seal and place in a cold storage workshop at 4 to 6 ° C for 8 to 12 months. 6. Packaging and storage: processed caviar must be stored in iron or canned bottles. The Heilongjiang carp and cod roe, which have been treated with salt for more than 30 days, are washed with saturated brine, filtered, and then packed into iron or canned bottles of a certain specification, and the air is taken out and sealed by ultraviolet disinfection. The shelf life of normal temperature is 12 months. (5) Quality characteristics. The palate is crispy, slightly spicy and has a fragrant smell. The size of the seeds is uniform and complete, free of foreign matter, allowing a small amount of broken grains, the surface of the caviar is shiny, and the oil black has a yellow ring.
