On November 27, 2008, the technical department organized a one-day sea cucumber seedling technical summary meeting organized by the head of the sea cucumber seedling project of each branch and the technicians involved in the sea cucumber seedling raising. The meeting was held in the conference room on the second floor of the Dawa headquarters. There are 18 people in total.

The main purpose of this summary meeting is to build a platform for our company's sea cucumber seedling technicians, so that we can fully communicate here. Combined with the sea cucumber seedling work last year, we will compare the sea cucumber seedling situation of the company's branches and other seedling farms this year. , learn from each other's strengths and make up for the shortcomings, find our gap in sea cucumber seedling technology, improve the company's sea cucumber seedling yield per unit, and pursue higher yield goals.

At the summary meeting, the directors of each nursery introduced their work this year, analyzed their shortcomings, and talked about their personal experiences in nursery. Among them, Chang Tianpeng of the nursery farm of Rongxing Branch believes that the water quality control in the nursery work this year is not very good, the white seedlings are attached late, and no remedial measures have been taken. At the same time, due to the use of bait in the later stage, the seedlings have staged stressful disease, which affects the growth of the seedlings. Qin Yu, director of Haijing Salt Industry's nursery farm, believes that this year, due to the relatively fat water quality and abundant algae bait in the water, the method of spreading seedlings with high density in the early stage, changing a small amount of water in the middle, and feeding less bait, the effect of attaching the board is better, and in September Before the drug has been mainly based on prevention, the seedling condition has been relatively stable and the growth rate is also faster. Feng Jialing, director of Jinzhou Nursery Farm, believes that the first batch of seedlings only had a few ponds this year, and the second batch of seedlings had a high density on the board. However, due to the thin water quality and low load capacity in the water, the white seedlings on the board in the early stage grew faster. It is not very fast, the number of seedlings is large after the plate is removed, and the stocking density is too large during the later cultivation period, which affects the normal growth of the seedlings, resulting in the size of most of the seedlings being sold at around 3000-8000 heads, which affects the yield. Qu Yingfeng, manager of Erjiegou Branch, believes that this year Erjiegou has more water bodies, but the number of white seedlings attached to the board is small, and some workshops have low stocking density in the later period, which wastes water bodies. Luo Yongming, the head of Sea Crystal Salt's seedling breeding, believes that this year's seedlings did not grow very well in the early stage. In the later cultivation process, the stocking density was moderate, the seedlings were cultivated in time, and the growth conditions were good. When the water temperature dropped in October, it still did not affect the growth. Liu Fu, manager of Rongxing branch, and Sun Zhongzheng, head of the nursery, also talked about their own experiences and analyzed the shortcomings of nursery work. The technicians participating in sea cucumber nursery in each branch also listed the problems they found in their work and communicated with them. Let's discuss together.

This sea cucumber seedling summary meeting combined the technical operation methods of other nursery farmers, analyzed our shortcomings in production, and took out some key issues to discuss together, and summarized the following issues. Analysis and analysis: 1. Control of water quality; 2. Control of seedling cultivation time; 3. Problem of drug use in seedling cultivation; 4. Control of cultivation density; 5. Feeding of bait; in management.

Through this summary meeting, everyone analyzed and discussed the problems in our company's sea cucumber breeding process this year, learned the advanced experience of other nursery farmers, and made preliminary suggestions and plans for next year's sea cucumber breeding work. Next year's sea cucumber seedling work will lay the foundation for improving unit yield, reducing costs, increasing production, winning the market and creating benefits.
