On June 11, an on-site training session on sea cucumber seedlings organized by the production department was held at Erjiegou Base. The main purpose of this training session was to summarize the production situation of the previous period, find out the problems, and provide a basis for the follow-up sea cucumber seedling raising work. . At the training meeting, each base introduced their own situation one after another. The most concentrated problem was that the big ears began to sink when they changed their shape. Through everyone's description and analysis, the main reason was the water used for seedling raising, which was used by Rongxing Branch and Delta for raising seedlings. The water is thinner, more transparent, and lacks phytoplankton; the reason for Erjiegou is obvious, because the water that hits the workshop has a sudden change in water quality. A pond has a large number of wart hair rotifers, and the survival of the pond seedlings is obviously affected by pH. In addition, there is a certain relationship with the type of bait and medication. In addition to the managers of the branches and the sea cucumber nursery managers, Luo Yongming and Feng Jialing also participated in the training. They also introduced the production situation and put forward some good suggestions, which benefited everyone a lot. Finally, Mr. Zhang asked everyone to go back and further study the specific solutions, try everything possible to keep the last batch of seedlings, pay attention to the quality of seed ginseng, improve the board rate, and take a look at other farms to learn about the outside situation, strengthen communication.
