What is the scheme and effect analysis of popularizing sea cucumber climbing in Chengyang area of Qingdao?

This is the most economical scheme to promote climbing, and most farmers in Chengyang area used this scheme in the early stage. The sea cucumber began to climb out after changing water for about 5 days, and the sea cucumber after climbing out was in poor condition. According to the observation, the number of climbs per pool of farmers using this scheme is 10~30 times, and the effect is not ideal.

2. By using irritating drugs:

This scheme is rare, and we are opposed to its use. Through interviews, it was found that some farmers chose to use killing drugs to stimulate sea cucumbers and speed up the climbing of sea cucumbers. After taking the medicine, the water became crystal clear, and sea cucumbers appeared around the cage for about 3 days, but most of them were in a state of stress contraction. 1~ 10 sea cucumber was found in some ponds, but most of them did not appear. Moreover, the disinfectant will kill the water very thinly. According to past experience, moss will break out in the pond in the second year, and it is difficult to feed water and fertilize after entering the high temperature period.

3. Enhance immunity by changing water and improving the bottom;

This is a very popular scheme in Chengyang area. /kloc-at the beginning of 0/0, farmers changed the water in the pond and gradually lowered the water level to improve transparency. Then use "Double Andy" to disinfect the pond and change the bottom. Sea cucumber lives at the bottom of the pond, so the quality of the bottom of the pond directly affects the physique and normal growth of sea cucumber. Spraying "Oligosaccharide 863" to the whole pond regularly can improve the physique of sea cucumbers, which can solve the problems of large energy consumption, weak physique and long transition process from dormancy to climbing in summer. After visiting, it was found that the climbing time of sea cucumber in the pond using this scheme was 8~ 10 days earlier than that in the surrounding ponds. After climbing, the sea cucumber was in good condition and grew rapidly.

To sum up, there are many factors that affect the crawling of sea cucumbers. Single water change stimulation or drug stimulation is not only ineffective, but also may bring hidden dangers. Therefore, we must fully consider the water quality, sediment, physique and other factors to promote the early crawling of sea cucumbers, truly achieve the goal of early breeding and rapid growth, and obtain higher yields and profits.
