What are the 8 characters of the 8-character aquaculture scripture?

Using eight words to comprehensively and systematically summarize the experience of fish farming production tools is a creative summary of my country's pond fish farming workers. The eight concepts are interconnected and form a multi-level network structure.

Fish farming must have a good water environment, a sufficient number of fish species with ideal sizes, and enough cheap, nutritious feed. "Water", "seed" and "bait" are the three basic elements for raising fish, and are the material basis for high and stable production in ponds. All technical measures for raising fish are determined based on the conditions of "water, species, and bait". The three are closely related and restrict each other, which is the first level of the "Eight Fish Breeding Manual".

"Mixed" refers to polyculture, that is, raising different types of fish in the same water body. Polyculture is In the long-term production practice, Chinese fishermen have gradually accumulated valuable fish farming experience by observing the relationship between fish, skillfully using their mutual advantages, and limiting or minimizing their conflicts or disadvantages as much as possible. The production potential of "water, species, and bait" can be brought into play. "Dense" is based on the biological basis of polyculture, the correct use of the interrelationships between various fishes, and the reasonable use of the specific conditions of "water, species, and bait". Intensive culture further makes full use of the pond water body and bait, and brings into play the production potential of various fish groups. "Round" is to extend and expand the utilization time and space of the pond on the basis of "mixing" and "dense", which not only makes The types and sizes of pond polyculture are further increased, and the pond is always maintained at a certain density throughout the breeding process, maintaining a reasonable capacity, maximizing the production potential of the water body, and ensuring balanced marketing of fish products. There is a year-round supply of live fish in the market. It can be seen that "mixing, density and rotation" are one of the important technical measures for high yield of the pond, and are the second level of the "Bazi Fish Culture".

Practice has proved that only the material basis of "water, seeds, and bait" and the technical measures of "mixing, density, and rotation" cannot guarantee stable and high yields. The main factor in mastering and applying these technical conditions is people. All fish farming measures. Only by giving full play to people's subjective initiative and comprehensively utilizing these conditions and technical measures through "prevention" and "management" can we achieve stable and high yields. It can be seen that "prevention" and "management" are the fundamental guarantees for stable and high yields in pond fish farming. Both are closely related to the aforementioned six concepts and are the third level of the "Bazi Fish Farming Classic".

With the development of production, the "Bazi Fish Farming Classic" should be continuously enriched and improved. Give it modern content. There is an urgent need to use modern testing methods to carry out experimental research on controlled ecosystems, and to refine a large number of qualitative and descriptive data in the "Bazi Fish Farming Classic" into quantitative rules. Use quantitative data to show the relationship between concepts. Electronic computers should be gradually used to conduct statistical analysis, and through the coding and storage of various parameters, automatic control and management should be carried out according to the ecological changes (information) of the pond, so that the ecological conditions of the pond are more in line with the requirements of fish growth and stabilized. Best condition.

To this end, it is necessary to conduct an in-depth study of the quantitative laws among the eight concepts of the "Bazi Fish Farming Classic" from the perspective of the ecosystem, and comprehensively apply them in production tools and strictly enrich them in order to further improve The theoretical level of pond fish farming promotes stable and high yields.
