Researcher Li Zhongjie of the Institute of Hydrobiology, Chinese Academy of Sciences, said that the project has carried out applied basic and technical studies since 2001, tracked and monitored the physicochemical environment and various biological resources in the lake area, systematically studied the nutritional pattern of fish communities in the experimental lake area, and used quantitative models. The energy flow characteristics of lake ecosystems, the optimal demand of squid for bait fishes, and the conversion efficiency of squid to different groups of bait fishes were analyzed; and microscopic metal markers were used to study the squid symbol retention rate and post-discharge Growth characteristics, range of activity and catch rate. Biotechnology is currently being used to study the genetic diversity of salmon in different lakes and find suitable molecular markers. On the basis of these studies, a suitable stocking amount of lake trout was put forward, and the technology for raising and raising fish of lake trout was perfected. A lake fishery management model based on the population dynamics of food organisms and stocking trout was established, and scientific and technological achievements were achieved. A higher degree of ripening and application level. In the 150,000-mu lake lake area, the annual production of carp rose from 20,000 to 116,000 kilograms, the annual output value was 3.517 million yuan, and the annual profit and tax was 2.015 million yuan, exceeding the contractual economic indicators.
According to reports, the squid uses other small fish as food and needs to be farmed with other fish. Therefore, it seems that the yield of squid per mu does not seem high, but the actual output per squid can be greatly improved. Mackerel is a high-class luxury fish and has a strong market demand. Compared with the lake's traditional stocking fishery, carp breeding and fishery can not only achieve higher economic benefits, but also contribute to water quality protection, and has a wide application prospect in the middle and lower reaches of the Yangtze River. .

Aquatic Technology of Chinese Academy of Sciences Aquatic Aquaculture Technology Can Increase Production by 5 Times
A few days ago, the “Industrial Demonstration of Lake Eel and Aquaculture Technology†project undertaken by the Institute of Hydrobiology, Chinese Academy of Sciences, passed the acceptance review in Wuhan. This project can increase the production of carp by five times.
Denilco flood control products are mainly used in municipal management, smart cities, water conservancy and drainage, construction, rail transit, factory property management, and relevant departments of emergency management bureaus;
Water absorbing expansion bag
Denilco water absorbing expansion bag has a wide range of applications and can be used for dam heightening and blockage, water containment and overflow prevention, engineering interception, blockage of hidden ditches and holes, reinforcement of flood control dams at any time, temporary flood control works such as urban waterproof sub embankments and block waterproof walls in flood control and emergency rescue. Before absorbing water, it weighs only 275 grams, and after 2-3 minutes of absorbing water, it can reach 20 kilograms. During emergency rescue, it can replace the soil source and quickly construct rescue projects to reduce losses caused by the lack of soil source on the rescue site and inability to rescue in a timely manner.
