On February 11, 2009, chaired by the Liaoning Provincial Department of Oceanography and Fisheries, relevant experts were invited to the delta scientific research base of Panjin Guanghe Aquatic Products Co., Ltd. to carry out the scientific research project "Environmental regulation of subglacial water in seawater ponds" undertaken by the Provincial Department of Oceanography and Fisheries. The "Theoretical and Technical Research" project has been site-accepted. The members of the acceptance group are: Tan Kefei, researcher of Liaoning Institute of Marine Science; Jiang Haishan, director of Liaoning Provincial Department of Oceanography and Fisheries; Bai Guofu, director of Panjin Fisheries Research Institute; Jiang Zhiqiang, professor of Dalian Fisheries College; Deputy Station of Liaoning Fisheries Technology Promotion Station Long Zhang Chi.

Chairman Li Xiaodong accompanied the members of the expert group to the Delta branch for on-site inspection. The chairman introduced the project "Theoretical and technical research on the regulation of subglacial water environment in seawater ponds" in the R&D center, and then the expert group went to the seawater pond to overwinter on-site. Field testing of methods for overwintering fish and seawater-related physicochemical indicators. The acceptance group randomly sampled for measurement. The testing items included dissolved oxygen, temperature, salinity, transparency, water depth, ice thickness, underwater light transmittance, types, specifications, and survival of overwintering organisms. At the same time, a natural seawater overwintering pond was selected. The relevant physical and chemical indicators were tested, and the differences in the physical and chemical indicators after the adjustment of the water environment under sea ice were compared from the results, and a sampling survey of seawater biomass in the pond was conducted.

Finally, the acceptance team held an acceptance review meeting in the conference room on the fourth floor of the R&D center. The experts at the meeting reviewed the relevant materials according to our company's acceptance of the project, and conducted on-site questions and answers on the relevant issues of the project. Acceptance report, agree that this project has passed the acceptance. The successful acceptance of the project "Theoretical and technical research on the regulation of subglacial water environment in seawater ponds" confirmed the scientific research and technical level of our company, obtained good technical experience, and added technical reserves for future scientific and technological research and development.
