I have longed for the underwater world since I was a child. The colorful corals, free fish schools, fierce and terrifying sharks...everything under the sea makes people feel mysterious and wonderful, and makes people want to dive into the blue ocean. Check it out. It is a pity that after learning for a long time, the editor can't swim, but becomes very afraid of water. Fortunately, there is an aquarium, separated by a layer of hard glass wall, Xiaobian this land duck can also watch the mysterious and beautiful underwater world up close! Let’s take a look at the three most dazzling aquariums in the world with the editor today~ 1. Dubai Aquarium The Dubai Aquarium, the Dubai Mall, a large shopping mall under the world's tallest tower "Burj Khalifa", is a miracle in the history of engineering. It has a vast space, equivalent to the area of 50 football fields, a 3-story building, and a pedestrian passage made of pure glass that allows visitors to more intuitively appreciate the magic and beauty of the underwater world. The Dubai Mall Aquarium opened in November 2008. The aquarium sightseeing corridor is 51 meters long, 20 meters wide, and 11 meters high. It has a water storage capacity of about 10 million liters and houses approximately 33,000 species of sharks and stingrays. Aquatic creatures. 2. Okinawa Churaumi Aquarium The "Churaumi Aquarium" located in the Ocean Expo Park on the Okinawa Peninsula has a construction area of approximately 10,000 square meters and has 77 display tanks. The aquarium is known as the world's first: the first in water tonnage, the largest number of fish species, the largest tank thickness, the world's largest species of sharks, and the world's first artificial breeding of natural corals in an aquarium. There are a total of 650 species of essence fish and 75,000 various exotic fish species in the aquarium. The largest "Kuroshio Sea" tank in the museum has a water volume of 7,500 cubic meters. Standing in front of the huge viewing window recognized by the Guinness Book of World Records as the world's number one, you can enjoy watching a variety of fish such as the 7-meter whale shark. In the aquarium, visitors can also directly touch the beautiful and cute little life in the sea, such as starfish, sea cucumbers, sea snakes, sea urchins, crabs, etc. 3.Georgia Aquarium The Georgia Aquarium is the largest aquarium in the world, located in Atlanta, Georgia, USA. The total water storage capacity is 22,000 cubic meters, and there are about 100,000 species of marine life in the museum. According to the management of the aquarium, 60 aquariums of varying sizes will be placed in the aquarium. The largest aquarium will account for three-quarters of the total aquarium volume. The largest fish in the two oceans will be stocked there. -Whale shark. Unlike the linear design of traditional aquariums, the Georgia Aquarium has five different exhibition areas, all arranged around the atrium. These exhibition areas are followed by Georgia ...

How to prevent the occurrence of diseases during the high temperature period? Now it's the high temperature period, the highest temperature has exceeded 30 ℃, it is also a period of frequent diseases, especially the diseases dominated by bacterial diseases, which will bring a new round of crisis to the entire aquaculture industry. Therefore, how will we minimize the disease in this hot season? We should all understand a simple truth: disease is easy to prevent, but it is quite difficult to treat. However, in the actual production process, farmers often think of treating fish and shrimps when they are diseased, but when a disease is discovered, the treatment often only reduces the loss, and some even lose money. Therefore, we must know how to take precautions and control the disease before it occurs, rather than thinking about treatment when you are sick. How can we prevent problems before they happen? 1. During the high temperature period, due to the hot temperature and high water temperature, the organisms in the water are in a rapid growth period, especially the growth and reproduction of microorganisms are vigorous, so bacterial diseases are the main diseases during this period; 2. Due to the high water temperature, the aquaculture animals are also in the rapid growth period, fish and shrimp eat vigorously, have a large appetite, and eat more, so hepatobiliary syndrome is also the main disease during this period; 3. Due to the high water temperature, the algae grow vigorously in the water, and the dissolved oxygen in the upper layer of the water body is supersaturated, but the dissolved oxygen in the lower layer of the water body is often in a state of insufficient, mainly due to thermal stratification and the large amount of oxygen consumption by the bottom microorganisms, and the feed is too much. Therefore, the large accumulation of harmful substances such as ammonia nitrogen and nitrite was also the main disease during this period. Diseases in the high temperature period often do not occur individually, but occur comprehensively. That is, the above three conditions occur simultaneously or more diseases occur at once. Therefore, when a disease occurs, it is quite difficult to control the disease at once. How to prevent the occurrence of diseases during high temperature? 1. Reduce the water temperature: The water temperature can be reduced by changing the water; set up shading sheds or shading nets; speed up the flow of water, such as using more aerators; splashing "stable VC" and other products that can cool down! 2. Reduce the accumulation of harmful substances such as ammonia nitrogen and nitrite: On the one hand, it is necessary to reduce the amount of feed; on the other hand, oral administration of "lactic acid bacteria", "highly active bacillus" and other beneficial bacteria can reduce the discharge of harmful substances such as ammonia nitrogen and nitrite in the feed; the water can be changed regularly Water; regular use of microbial...

The plum blossoms have already begun in Jiangsu this week. The next thing you will face is high temperature. The best temperature is now above 35 degrees. The high temperature this year is expected to be stronger than any year. Then your pond can now accept the high temperature. Challenge? The author will remind you of the recent situation in Tangkou. If you don’t do a good job of remediation, what should we do before the high temperature comes? Pond water level: 1. Control the water level. When the high temperature comes, the pond water temperature will be higher, and the dissolved oxygen in the pond will also be lower. Then we need to add the water level. Many people ask me how much the water level should be increased. Then I will tell you a method here. Go to the pond at 3 o'clock in the afternoon and make sure that the water level at the bottom of the pond is kept cool at 20-30 cm. Pond aeration: 2. Aeration, most of the problems facing high temperature are caused by lack of oxygen, so how do we correctly ensure that the pond has sufficient dissolved oxygen: do not turn on the aerator at noon, it is best to add fresh water or turn on the aerator in the early morning; when using medicines Be cautious and avoid using excessive oxygen-consuming drugs; in the evening, you must promptly turn on the water pump or aerator in time when floating heads appear in the pond at night. Waterweed maintenance: 3. Aquatic plants. Excessive temperature will cause the growth of Elodea to stop or even rot. Therefore, it is necessary to maintain Elodea in time before the high temperature. Now you can use Algae Surging/Water Gold Cream + Caolijian 2 to improve vitality and repair Damaged cells; if the aquatic plants have decayed, remove the aquatic plants in time, and replace part of the dirty water to detoxify and improve the bottom; if there is no aquatic plants, replenish water peanuts or black algae in time to ensure that there are aquatic plants in the pond. Provide a place for river crabs to shed their shells. Physique: 4. Before the damage and high temperature comes, the crabs should be supplemented with nutrition. The crabs eat unstable at high temperatures. Therefore, crabs with weak physique will suffer large-scale damage in the face of high temperature. It is recommended to spray Jinwei'an + ionized calcium before the high temperature. During the feeding period, the feed must be mixed with "Gan Shukang + Dink + Budobacterium 110/Shijunhuang" to increase the appetite of crabs. Pond disinfection 5. Disinfection, the activity of crabs is relatively weak in high temperature days, so avoid using excessively irritating drugs during disinfection. It is recommended to use a mild disinfectant, Hiruzun, to pour outside at 6 o'clock in the morning to disinfect the pond. High temperature is the time when ponds are tested. Ponds will have a lot of problems during the high temperature period. Don't panic when you encounter problems. You must seek professional guidance...

What are the common violations of wastewater law? Protecting water ecology, preventing water pollution, and improving water environment are an important part of environmental protection work. On January 1, 2018, the new "Water Pollution Prevention and Control Law of the People's Republic of China" was officially implemented, which has higher requirements for wastewater treatment and management of wastewater treatment facilities. Next, I would like to share the "wastewater" violations that have been common in the law enforcement process in recent years. 1. Irregular operation of wastewater treatment facilities The abnormal operation of wastewater treatment facilities, including the decommissioning of wastewater treatment facilities, the damage and deactivation of a certain link of the wastewater treatment facilities, the waste water exceeding the treatment link, the waste water treatment facilities not being dosed and maintained according to the design requirements, and the current wastewater volume exceeds the wastewater treatment facilities The average daily processing capacity and so on. Legal link: Article 39 of the "Water Pollution Prevention and Control Law of the People's Republic of China": It is prohibited to use seepage wells, seepage pits, cracks, karst caves, privately set up hidden pipes, tamper with or forge monitoring data, or improperly operate water pollution prevention measures, etc. Prevent and control discharge of water pollutants that evade supervision; in accordance with the provisions of Article 83, paragraph 1, (3) of the "Water Pollution Prevention and Control Law of the People's Republic of China", order to correct or restrict production, stop production for rectification, and impose a penalty of more than 100,000 yuan A fine of less than one million is a fine; if the circumstances are serious, it shall be reported to the authorized people’s government for approval and ordered to suspend business or close down. 2. Excessive discharge of wastewater Due to improper management of wastewater treatment facilities and the inability of wastewater treatment facilities to meet the status quo of the enterprise, the discharge of wastewater exceeds the standard. Legal link: Article 10 of the "Water Pollution Prevention and Control Law of the People's Republic of China" shall not discharge water pollutants in excess of the national or local regulations, water pollutant discharge standards and key water pollutant discharge total control indicators. According to Article 83, Paragraph 1, Item (2) of the Water Pollution Prevention and Control Law of the People’s Republic of China, if wastewater is discharged in excess of the standard, it shall be ordered to correct or restrict production, stop production for rectification, and impose a penalty of over 100,000 yuan and less than one million yuan. Fine; if the circumstances are serious, it shall be reported to the approved people’s government for approval and ordered to suspend business or ...
