Zhanjiang mariculture Technology (12.5)

OA show ('918 '); the future development of the mariculture industry needs to change the extensive management pattern by continuously increasing the scientific and technological content, and the development degree of the fine processing and bioengineering of marine products becomes the key Do you know that two out of every three sea pearls in the pearl necklace worn by Chinese people come from Zhanjiang? Do you know that two out of every three Guangdong prawns consumed all over the country are also produced in Zhanjiang? In 1999, Zhanjiang's marine industry totaled 13.2 billion yuan, ranking third in the province after Guangzhou and Shenzhen Among them, the output value of marine fishery is 4.33 billion yuan, accounting for 30% of the marine economy, ranking first in the province The proportion of marine fishery in Guangzhou and Shenzhen is less than 10% Science and technology make mariculture on the road to prosperity When it comes to Mariculture, experts come from Li Xing, director of Zhanjiang Municipal Bureau of ocean and fisheries, Guangdong Province He said that the achievements of mariculture in Zhanjiang depend on science and technology In 1991, the total output of prawn in China was 220000 tons, and by 1995, the output dropped sharply to only 50000 tons The output value of prawn in Zhanjiang was 9800 tons in 1991, but only 5600 tons in 1995 After continuous technical exploration and research, a breakthrough was made in the scientific and technological cultivation of prawn in 1996 The output of prawn exceeded 10000 tons in that year, and reached 24300 tons in 1999, accounting for 56% of the total output of prawn in the province and 20% of the total output of prawn in the country It is estimated that the shrimp production in Zhanjiang will exceed 30000 tons in 2000 In the scientific and technological development of mariculture, Zhanjiang's breeding industry was first successful in the seedling project At present, 12 varieties have achieved success in artificial breeding and formed production scale In terms of pearl breeding control, the rare varieties of pearl, white butterfly shell, black butterfly shell and Penguin shell, have achieved success in breeding Secondly, there is more historical progress in shrimp diseases and insect pests Zhanjiang scientific and technological personnel creatively use fresh water to cultivate sea shrimp, adopting high-level breeding and closed half Closed culture and segmented culture have successfully controlled the spread of baculovirus of Penaeus vannamei, which is commonly known as white spot disease In particular, they have made remarkable achievements in inhibiting the large-scale incidence of pullout virus of Penaeus vannamei, which is banned by the relevant departments of the state They have changed the practice of breeding Penaeus vannamei, which is banned by the state for a long time, short-term, high-yield and high meat content, and made Zhanjiang sea water Third, the use of caisson culture and hanging culture and other advanced culture technology, so that the abalone produced less disease, low cost, high quality, thus won the gold medal of China Agricultural Exposition in 1999 In 1998, Professor Yu of Zhanjiang Ocean University extracted active substances from a kind of fish and developed a new national class a anti-cancer drug, which made a breakthrough in clinical trials and avoided the damage of healthy cells in cancer patients during chemotherapy The new drug made cancer patients no longer lose their hair in the process of chemotherapy After giving Professor Yu's example, director Li said: the development of bioengineering will be the key point for Zhanjiang to develop marine fishery and increase the added value of marine aquaculture It is predicted that in the next ten years, the total output value of Zhanjiang's marine economy will reach 45 billion yuan Zhanjiang will become a strong marine city from the present one, and the proportion of Zhanjiang's marine fishery will increase from 30% to 40% - 50% In order to achieve this goal, Zhanjiang mariculture industry will take the road of developing characteristic breed breeding and developing marine medicine, and through developing bioengineering and improving product gene, it will achieve the purpose of improving product quality and output of mariculture industry The future development of mariculture needs to change the extensive management pattern by increasing the scientific and technological content, and the development degree of marine products' fine processing and bioengineering becomes the key Acy (author:)
