Liaoning Marine Aquaculture UV Disinfector

Description :

　　Advantages of Liaoning Marine Aquaculture UV DisinfectorThe advantages of marine aquaculture are: concentrated development of certain economically valuable fish, shrimp, shellfish, and echinoderms (such as sea cucumbers), shorter production cycles, and higher yields per unit area. According to the breeding objects, marine aquaculture can be divided into fish, shrimp, shellfish, algae, and marine treasures. Among them, the ultraviolet disinfection equipment for marine aquaculture in Liaoning has developed rapidly in shellfish and algae marine aquaculture, while shrimp, fish, and marine treasures aquaculture is relatively weak. According to spatial distribution, it can be divided into enclosed ponds, tidal flats, harbors, and shallow seas. According to the degree of intensification, it can be divided into coarse cultivation (including care and management), semi intensive cultivation, and intensive cultivation, with coarse cultivation being the main type.

　　Marine aquaculture industry

　　Research scope of marine aquaculture industryincluding:

　　(1) Use seawater to enclose ponds, mudflat, harbors and offshore waters to control marine economic activities such as fish, shrimp, crabs, shellfish (including pearls), algae, sea cucumbers, etc

　　Plant cultivation;

　　(2) The seawater nursery promotes and preserves various marine animal and plant seedlings;

　　(3) Increasing aquaculture in offshore pastures (such as releasing, transplanting, artificial reefs, bubble screen or micro current net aquaculture, large-scale wind and wave resistant net cage aquaculture, etc.);

　　(4) Protection and breeding of seedling genes, prevention and control of pests and diseases, environmental pollution, research on nutritional feed, renovation of breeding facilities, and computer technology

　　Automatic breeding control technology, etc.

　　History and Current Status of Marine Aquaculture

　　According to the breeding method, it can be divided into single breeding, mixed breeding, and intercropping (such as intercropping with shellfish). China has a long history of marine aquaculture, such as the cultivation of pearl oysters, which originated in China. Hepu, Beihai, and Dongxing are known as the "hometown of pearls", while Zhanjiang is known as the "hometown of southern pearls". The foundation of the world's marine aquaculture industry is still relatively weak, but there is enormous potential for development. Artificial aquaculture (such as release, artificial reefs, and large-scale cage aquaculture in offshore areas) can be developed in coastal areas, harbors, inland seas, and shallow seas. Since the 1970s, due to the decline of traditional nearshore fishery resources, many coastal countries have successively announced the implementation of 200 nautical mile economic zones and exclusive fishing zones, promoting the development of marine aquaculture. In 1980, the output reached 3 million tons, especially in countries such as Japan, Russia, the United States, and Norway. China's marine aquaculture industry has achieved significant development in the past thirty years. China is a country with developed marine aquaculture in the world, ranking first in both aquaculture area (1579 thousand hectares, 2008) and total production. According to statistics from the Food and Agriculture Organization (FAO), the total output of China's marine aquaculture industry was only 100000 tons in 1955 and has gradually increased since then. In the past thirty years, it has experienced rapid development, exceeding 3 million tons in 1990 and rising to 13.4 million tons in 2008, accounting for 51.6% of China's marine aquatic product production and about 2/3 of the world's total marine aquaculture production. The great development of China's marine aquaculture industry is mainly due to the rise of shallow sea shellfish and algae aquaculture. For example, in 2008, shellfish production (10.08 million tons) accounted for about 75% of the total production, while macroalgae production (1.38 million tons) accounted for about 10.3%. Together, the two accounted for more than 85% of China's marine aquaculture production, while fish (740000 tons) and shrimp and crab (940000 tons) accounted for about 5.5-7%. It can be seen that China's marine aquaculture industry is still mainly based on shellfish and algae farming, and there is still a lot of room for development in terms of variety.

　　The impact of marine aquaculture on the environment

　　Most of the world's marine aquaculture systems have entered semi intensive or intensive aquaculture, and the feeding of feed and the generation of residual feed are important factors contributing to self pollution in aquaculture. Specifically, pollution from shrimp farming mainly comes from the release of N and P nutrients from newly formed residual feed, as well as a large amount of sulfides, NH4, and suspended solids in the aquaculture wastewater. In addition to residual feed, fish also include their feces and excreta, which contain nutrients such as N, P, and organic matter. These substances will have a eutrophic impact on water bodies and sediment. Overall, aquaculture self pollution belongs to organic pollution, which mainly increases the environmental load of N and P.

　　Driven by economic interests, many regions have developed aquaculture in a disorderly, unrestrained, and even gratuitous manner. Large scale reclamation has led to a reduction in sea area and tidal capacity, weakening the self purification ability of the ocean and exacerbating the deterioration of the water environment. The blind construction of net cages and the installation of suspended rafts by aquaculture owners on the sea surface have resulted in excessive aquaculture density, far exceeding the carrying capacity of the marine ecosystem, causing obstruction or disorder of the logistics and energy circulation of the marine aquaculture ecosystem, and leading to diseases. The decomposition of a large amount of leftover bait, debris, fish and shrimp feces, as well as household waste from aquaculture workers, produces a large amount of nitrogen and phosphorus nutrients, leading to eutrophication of aquaculture waters and providing a suitable ecological environment for red tide organisms, which is the root cause of red tide. Unplanned marine aquaculture is becoming an important source of pollution in nearshore waters, and even has a trend of surpassing land-based pollution. For example, in some aquaculture areas in Norway, the degree of pollution harm caused to the sea area and the severity of direct damage to the ecosystem far exceed land-based pollution

　　Aquaculture (seawater) aquaculture UV equipmentProduct Introduction

　　In the fields of aquaculture and ornamental fish farming, ultraviolet sterilization is becoming increasingly widely used. In the process of aquaculture, the reproduction of algae in water and the bacteria and viruses that cause fish diseases can both die and disintegrate within seconds under strong ultraviolet radiation. After UV sterilization and purification of water bodies, more than 99% of bacteria and viruses will be killed, thereby reducing the disease rate of fish, increasing aquaculture density and yield, and improving the ornamental value of ornamental fish.
