2, sea cucumber is a benthic aquatic animals, long-term life in the bottom of the water layer, so the environment of the bottom of the pool, affecting the growth and development of sea cucumbers. The bottom of the water layer is easy to accumulate sea cucumber feces, silt, bait, algae, a long time, the debris at the bottom of the pool began to rot and deteriorate, corrupting the water quality, breeding bacteria, molds and other pathogens, so the sea cucumber is very easy to disease. In order to ensure the healthy growth of sea cucumbers, it is necessary to regularly clean the bottom mud and regularly disinfect the pond.
3, choose to ensure that the quality of the sea cucumber fry chosen is qualified by the relevant quarantine department. When you look at the surface of the sea cucumber seedling, you can see that it is free of damage, clean, energetic, responsive to external stimuli, and has strong adhesion to the tube foot. When you turn the seedling back and forth with your hand, the seedling will stretch quickly, have strong adhesion to the tube foot, and the flesh spines will be firm as healthy seedling.
4, put density put density affects the production and quality of sea cucumbers. Therefore, according to the water quality of the ginseng pond, the stocking density should be reasonably controlled, roughly refer to the size of the sea cucumber 200~1000 heads?kg-1, then the density should be controlled at 60,000~120,000 heads?hm-2.
5, the time of stocking, pay attention to the timing, it is best to stock in the spring and fall seasons, mainly to see the water temperature, the water temperature in the spring at 7-10 ℃ should be stocked to improve the survival rate, so as to improve the survival rate. Convenient to improve the survival rate. Note: Rainy days, big waves should not be stocked.
6, before putting the ginseng seedlings, we should disinfect them with medicinal liquid to reduce the occurrence of sea cucumber diseases.
7. The water used for releasing should be sterilized by ultraviolet ray to make sure that the sundry microorganisms in the water can be effectively treated to ensure that the sea cucumbers are in a clean condition.
8. The living environment of the sea cucumber can reduce the breeding of bacteria.
9. For the sick pool, we should actively improve the water quality and increase the amount of water exchange, and take specific measures according to the specific situation of the sick pool.
10, for healthy adult ginseng, you can regularly use quicklime to disinfect and improve the resistance of adult ginseng.
