On December 2, 2011, the project of "Technology Research on Aquatic Economic Animals Overwintering under Ice in Seawater Ponds" declared by our company won the second prize of Panjin Science and Technology Progress. This project is an independent research and development project of the company. The unit has carried out preliminary application, and the application in 2010 shows that the application effect is good in fish and shellfish, and the application in sea cucumber and other species has great potential, and the application scope of the project can be further expanded.

This project passed the appraisal work organized by relevant experts organized by the Liaoning Provincial Department of Science and Technology in May this year, and the technology has reached the international advanced level. The project has developed comprehensive technologies for heat preservation and oxygenation of the subglacial water layer of seawater ponds, as well as oxygen supplementation technology for local circulation of subsurface water, zooplankton control technology, and subglacial fertilization methods. It provides a technical support for the large-scale development of marine aquaculture organisms overwintering in the northern region.
