?? Chinese sturgeon is a traditional nourishing food, has been favored by people since ancient times. Driven by interests, some industries and farmers have joined the ranks of raising elk. They lack scientific knowledge of educating people, blindly abuse drugs, and illegally enter the country to enter and shoddy, seriously damaging the image of Chinese emu in the hearts of consumers. . The introduction of pollution-free Chinese sturgeon breeding standards is of great significance in regulating aquaculture behavior, improving product quality and competitiveness, and promoting the safety, health, and sustainable development of Chinese sturgeon. The pollution-free Chinese sturgeon refers to the production environment, production process, and product quality that meet the relevant national standards and regulations. After being certified, it is qualified to obtain a certificate and permit the use of a non-environmentally hazardous product, the Chinese sturgeon. Among them, the pollution-free Chinese sturgeon producing area should meet the following three conditions: 1 The environment of the producing place is in line with the requirements of the environment of the production environment of pollution-free agricultural products. 2 The scope of the area is clear. 3 has a certain scale of production, production and management should be consistent with: A, the production process meets the standard requirements of pollution-free agricultural production technology. B. There are corresponding professional technicians and management personnel. C. There are perfect quality control measures and complete production and sales record files. Boluo County Yingshi Industrial Co., Ltd. is a subsidiary company of Guangdong Green Card Industrial Co., Ltd. and is engaged in the commercial breeding of Chinese sturgeon. In recent years, the “Green Card†brand of Chinese sturgeon produced meets the national pollution-free standard. In June this year, it was recognized as the first batch of pollution-free agricultural products by the Ministry of Agriculture. The specific quality control measures are reported below. 1. Seedling seedlings are one of the foundations of aquaculture production. Impaired germplasm caused by impure germplasm, inbreeding, and illegal importation of Chinese sturgeon to Chinese sturgeon, has a low survival rate, resulting in annual losses of more than 100 million yuan. The company's cultured Chinese sturgeon seedlings are all from the national level. Chinese sturgeon seed farm ---- Guangdong Green Card Industry Co., Ltd. The inbreeding age for reproduction is 4-10 years old and the parental weight is 2 kg or more. Seedling standard: Newly hatched seedlings of 3.5 grams or more, the web is red, the more red the more robust, no disability, lively action, responsive, can pull back with a strong hand pull, skirt thick, straight , thin body. 2. The aquaculture site is located in Luwu Village of Yokogawa Township under Luofu Mountain. The vegetation is good, the amount of mountain water is large, the water quality is fresh, the annual dissolved oxygen is above 4 mg/l, the COD is below 10 mg/l, and the ammonia nitrogen is no more than 0.2 mg. / L, the source water is in line with NY5051-2001 "No pollution food freshwater fishery water quality standard". The air quality level is in line with GB3095-1996 "Ambient Air Quality Standards". The environment is quiet, the sun is abundant, the ecological environment is good, there is no industrial "three wastes" and pollution of agriculture, urban life, medical waste. The water does not contain petroleum, acrolein, and Other organic substances, and the contents of 666, DDT, and heavy metals do not exceed the standards. The soil is uncultivated. The heavy metal content and pesticides do not exceed the standards and meet the GB 15618-1995 "Land Environment Quality Standards." In order to control the impact of breeding sites on the quality of pollution-free Chinese sturgeon. 3. The “green card†brand Chinese sturgeon used in feed cultivation is strictly produced in accordance with the “Regulations on the Administration of Feed and Feed Additivesâ€, the enterprise standard Q/LK11-2000, and the record number: QB/441900641911-2001. Detect harmful, toxic, heavy metals and pesticides in raw materials, prohibit the use of unqualified raw materials, and prohibit the addition of antibiotics, somatotropin, etc. From the source to prevent the entry of exogenous hazardous ingredients. "Green Card" brand Chinese sturgeon series feed is in compliance with NY5072-2002 "Safety Limits for Foods with Non-environmentally Harsh Food & Feeds". In the feed production process, use clean water, add fresh and non-polluted vegetables, use fresh, use, time, quality, positioning, control to eat in 2 hours, feed the way to feed on shore, residual bait for recycling , To reduce feed wastage and pollute the water quality. Every 50-80 quail only one ingestion point to avoid the damage caused by competition for food. The specifications of the outlet pond are neat, so as to ensure that the feed does not harm the quality of the Chinese sturgeon. 4. The hazards of the use of fishery medicines in fishery medicine are mainly manifested in the long residue of medicines. Once some fishery medicines are accumulated, they are difficult to be excreted by metabolism. For example, heavy metal medicines, some fishery medicines may cause abnormal development of quail, which was implemented in the whole breeding process of Chinese sturgeon. Ecological breeding, healthy breeding, biological control diseases, regular use of quicklime, bleaching powder to regulate water quality, targeted high-temperature seasons to add high-efficiency and low toxicity of Chinese herbal medicine, thereby minimizing the occurrence of disease, reduce the dosage, and for the prevention of diarrhea is strictly in accordance with NY5071 -2002 "Guidelines for the use of pollution-free food and fishery drugs" to eliminate the use and stealth accumulation of highly toxic and high-residue fishery drugs. 5. Water quality Chinese sturgeon is a reptile living in water. The quality of water will have an important impact on the final quality of the product. The source water is pure spring water, and the water quality of the pond is controlled by physical, chemical and biological controls to ensure that it meets the standards for fishery water quality. Physical regulation mainly includes rushing, changing water, aerating, aerating, removing silt in the bottom of the pond, and exposing the bottom of the pool to reduce the accumulation of toxic and hazardous substances at the bottom of the pool; chemical regulation mainly includes regular spilling of 15-20 mg/liter of quicklime , 2mg/L bleaching powder, to ensure the transparency of water quality in 25-35 centimeters, dissolved oxygen in 4 mg / l or more, COD in 10-20 mg / l, ammonia nitrogen does not exceed 5 mg / l; Fish, bacteria, algae, shellfish, water lettuce and other symbiosis, the implementation of the diversification of aquatic organisms, improve the circulation and circulation of water substances and energy, enhance the self-purification of pool water. The important measure is polyculture. Cod polyculture refers to the rearing of predatory fish (pipa, clams, tilapia) and filter-feeding (white, calyx) fish in Dianchi Lake, which can remove the residual baits and feces of Chinese sturgeon and control the plankton content. Increase dissolved oxygen in the water, reduce the occurrence of diseases, make the cultured water show a benign cycle, and minimize the use of fishery drugs. 6. Packaging and Transportation The packaging and transportation of Chinese sturgeon is the last link before the listing. It is forbidden for human operation, mechanical damage, and infection to prevent the appearance and color of the product.
