Three-dimensional composite rearing method of sea cucumber seedlings and adult ginseng

Abstract

The invention relates to a three-dimensional compound cultivation method of sea cucumber seedlings and adult ginseng, which is characterized in that adult ginseng is cultured in a sea cucumber breeding pond, and young ginseng seedlings are cultivated in a suspended seedling cultivation workshop built in the breeding pond. The replacement water with temperature difference in the suspended seedling cultivation workshop flows directly into the multiplication pond, and the inflow ratio is controlled to regulate the water temperature in the multiplication pond in winter ≥ 5 ℃, summer ≤ 24 ℃, the optimum temperature is 10-15 ℃, and the inflow of replacement water brings success Participate in the bait and no longer add other bait. The suspended seedling cultivation workshop regulates the water temperature at 19-23°C, adds baits such as chaetoceros and salina, and renews the water body by flowing water, with a daily flow of 50%-100%. Seedlings are released every spring and autumn in the sea cucumber breeding pond when the daily water temperature is ≥10°C and the daily minimum water temperature is ≥5°C. The water in the pond is changed 4-6 times / month, and the water volume is 30%-50% each time. The method solves the problems of low land utilization rate for sea cucumber cultivation, low water exchange and bait utilization rate of sea cucumber nursery ponds, and the like.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for three-dimensional compound cultivation of sea cucumber seedlings and adult sea cucumbers. Background technique [0002] Sea cucumber farming is an emerging aquaculture industry in my country in recent years, with increasing output value and various farming methods. At present, most sea cucumbers are cultured in ponds in tidal flats. With the gradual expansion of the breeding area, the land resources of ponds suitable for sea cucumbers in coastal areas are gradually decreasing, and the area of ​​ponds that can be newly developed for sea cucumbers tends to be tense. At the same time, with the substantial increase in the breeding area, the demand for sea cucumber seedlings has risen sharply, and there is an urgent need for a large number of sea cucumber nursery farms to be constructed. Sea cucumber nursery farms are located in the same area as sea cucumber breeding areas, an...
