On February 7th, 2065438+00, CCTV's seven sets of Science Park broadcast the talk show "Raising Misgurnus but Not Misgurnus". 20 10 12 16 broadcast the talk show "Additional Benefits of Raising Loach".
3. Adopt the technical route of semi-artificial propagation without soil in shallow water, that is, artificially select the parent eel, put it into the culture pond at the right time, feed it with feed and live bait, use drugs, especially Chinese herbal medicine, to induce labor, and take it out in time for artificial drip incubation after natural spawning and fertilization, so as to achieve the purpose of large-scale propagation. The relationship between reproductive behavior and gonad development of Monopterus albus and ecological factors (density, light, temperature, water flow, pH, aquatic plants and water level) was discussed. It is found that the field area of Monopterus albus without dormancy in winter can also be successfully semi-artificially propagated.
4. Innovatively extract effective components from aquatic plants (especially water peanuts) for drug control, comprehensively utilize resources, adopt ecological technology for integrated pest control, increase biodiversity, fully tap the potential of Chinese herbal medicines, use food chain amplification and biological carriers to transfer drugs, improve drug efficacy, and realize environmental protection breeding. The invention patent "a medicine for preventing and treating aquatic animal diseases and its preparation method" has been declared, and the authorized invention patent "Monopterus albus wild seedling medicine bait and feeding method" has been obtained.
5. Invented a fish nest which is conducive to the free entry and exit of eels, which overcomes the shortcomings of high local density of eels caused by the entanglement of simple aquatic plants, and the inconvenience of free entry and exit of PVC pipes, making soilless culture and industrial culture of eels possible. The invention patent "Monopterus albus soilless culture fish nest and its setting method" has been declared.
6. Systematically study the epidemiological characteristics of important diseases and insect pests of Monopterus albus in Yangtze River and Yellow River basins. Soaking eel species with self-developed drugs can not only get high-density exercise, but also solve a series of problems such as partial mucus shedding and rotten tail of eel in the market. Has obtained the authorized invention patent "quantitative screening method for wild rice field eel fry".
7. The feed formula and quality improvement additives in different seasons and growth stages were studied for the first time. The compound feed of Monopterus albus has a low feed coefficient and a good attractant has been found. The technical achievements were transformed by Zhengzhou Secco Biotechnology Co., Ltd., and the products were welcomed by farmers.
8. The feeding ecology and behavior ecology of Monopterus albus were systematically studied. By studying the food selectivity and cannibalism behavior of Monopterus albus, the basis for reasonable polyculture was provided. The effects of temperature, fish nest, pH, dissolved oxygen and salinity, body weight and other ecological factors on the feeding of Monopterus albus were systematically studied, and the maximum feeding rate of Monopterus albus under different body weight and temperature conditions was predicted by equations. It is confirmed that Monopterus albus from different sources and different domestication methods have obvious circadian feeding rhythm. The nesting behavior of Monopterus albus and its selectivity to fish nests under different weights and different water depths were studied. It was found that changing water and feeding significantly stimulated the defecation activity of Monopterus albus.
9. The typical artificial food chain (such as "fermentation substrate-earthworm-eel") was analyzed. "Dandelion-tadpole-eel"; "Wheat bran-Tenebrio molitor-Monopterus albus" etc.) provides a theoretical basis for the rational design and utilization of the food chain of Monopterus albus and reducing the breeding cost.
10. Creatively introduce earthworm ecological filtration technology and bioremediation technology, especially animal remediation technology into aquaculture, establish a new bioremediation model of microbial-plant-animal joint remediation, and realize the efficient goal of integrating eel (loach) raw materials, feed cultivation and water purification. "A method for controlling water eutrophication by using special food chain" has applied for an invention patent.
1 1. Monopterus albus, loach and crayfish were successfully cultured in saline-alkali land for the first time. Experiments show that the maximum feeding rate of Monopterus albus is the highest when the salinity is 6 or 4. Monopterus albus is discharged in batches, but the batches are different under different salinities, and the time required for discharging each batch of Monopterus albus is very significant.
12. The cannibalism of Tenebrio molitor, the diurnal variation of pupation and emergence, and the selenium-enriched ability were studied, and the effects of feed types and feeding density on the growth rate, mortality rate, pupation rate and nutritional components of Tenebrio molitor larvae were determined. Invented the automatic separation technology of earthworm and Tenebrio molitor, and obtained the authorized invention patent "New harvesting method of Eisenia foetida".
13. Take the lead in carrying out systematic research on earthworm decomposition treatment technology of municipal sludge in China, and establish demonstration engineering bases in Xuchang and other places. Optimum ecological conditions (earthworm density, substrate temperature, optimum carbon-nitrogen ratio, etc.). ) Municipal sludge was degraded by earthworm, and good treatment effect was obtained. The results show that 1 kg earthworm can transform at least 2 kg earthworm dung every day, and the sludge is reduced by more than 30%. The percentage of heavy metal content decreased after earthworm enrichment, and the order of earthworm enrichment coefficient for various heavy metals.
14. The ecological engineering model of Alternanthera philoxeroides resource utilization was put forward. It was found that the different proportions of Alternanthera philoxeroides and wheat bran significantly affected the specific growth rate and material and energy conversion efficiency of Tenebrio molitor larvae, and significantly prolonged the developmental duration of Tenebrio molitor pupae. Using this equation to predict the maximum feeding rate of Ampullaria gigas at different weights and temperatures can effectively control the outbreak of Ampullaria gigas and Procambarus clarkii.
15. Integrate environmental engineering and ecological engineering technology into livestock manure treatment, integrate anaerobic fermentation technology, biogas slurry culture technology, loach and eel culture system, earthworm biodegradation treatment technology and environmental deodorization technology, and construct a compound ecological engineering and circular economy model for livestock manure treatment. The project "Demonstration Research on Ecological Engineering and Circular Economy of Livestock and Poultry Manure Treatment" passed the technical appraisal on June165438+1October 6, 2008. As a typical case, it was compiled into the graduate textbook "Ecological Engineering" (2008) recommended by the Ministry of Education, and demonstration bases were established in Zhengzhou and Fuyang. On June, 2009 10, CCTV 7 Science and Technology Park broadcasted the program "Science and Technology on the Chain (II): Cow Dung Chain", which reported that Dr. Zhou Wenzong helped Zhengzhou cattle farmers to control cow dung pollution with the new technology of ecological farming circular economy, and realized the extension, value-added and recycling of the ecological chain.
