Technical Field

The invention belongs to the field of aquaculture, and particularly relates to a safe summer culture pond and a culture method for stichopus japonicus pond culture.

Background

The stichopus japonicus culture comprises indoor industrial culture, outdoor pond culture and net cage culture in sea areas. In the outdoor pond culture, in summer in the north, the stichopus japonicus needs to sleep in summer due to the rise of water temperature, the seawater temperature during the sleep in summer is 20-32 ℃, the sleep in summer generally starts in 6-7 months and ends in 9-10 months for about 3 months. During the period of sleep, the sea cucumber is inactive, but consumes self-stored energy and respiratory metabolism. As farmers, the long-term growth retardation and weight reduction of sea cucumbers are not desired. Therefore, the method shortens the summer sleeping period, namely, the sea cucumbers enter the reef late and leave the reef early, does not lack oxygen and does not have toxic diseases in the summer sleeping period, and is one of effective methods for improving the yield of the sea cucumbers.

Disclosure of Invention

The invention aims to solve the technical problem of providing a safe summer culture pond for stichopus japonicus pond culture, wherein the pond is convenient for inducing stichopus japonicus to enter a deep water area for safe summer, enter a fish reef for summer sleeping at a late point, and can also induce the stichopus japonicus to come out at an early point for normal feeding activities after summer is finished.

A safe summer culture pond for stichopus japonicus pond culture is characterized in that more than one step group which is symmetrical left and right is arranged at the bottom of the culture pond, a central platform layer is arranged in the middle of each step group, a first platform layer, a second platform layer and a bottom platform layer are arranged on the left side of each step group, the right side and the left side of each step group are symmetrical, and the height difference between the central platform layer and the first platform layer, between the first platform layer and the second platform layer and between the second platform layer and the bottom platform layer is 0.5-0.8 m; the adjacent ladder groups share the bottom platform layer; an artificial fish reef is arranged on the bottom platform layer.

Further, an inflating device is arranged on the bottom platform layer; the gas is cooled cold gas, and the temperature of the cold gas is lower than 18 ℃.

Further, the width of the central platform layer is 300-.

Further, the central platform layer, the first platform layer, the second platform layer and the bottom platform layer are arranged longitudinally along the culture pond.

Furthermore, the widths of the central platform layer and the bottom platform layer are correspondingly marked on the sides of the culture pond.

Further, the height difference between the central platform layer, the first platform layer, the second platform layer and the bottom platform layer is connected through a gentle slope, and the slope is less than or equal to 75 degrees.

The invention also provides a method for culturing by using the culture pond, which is characterized in that stichopus japonicus seeds are uniformly sown on the central platform layer, the first platform layer and the second platform layer; when the temperature of water on the central platform layer rises to 20-22 ℃ in summer, inducing stichopus japonicus to enter the bottom platform layer by bait casting, gradually reducing bait casting on the central platform layer, wherein bait casting areas are firstly concentrated above the first platform layer and the second platform layer, a small amount of bait casting is carried out above the bottom platform layer, 5-8 days later, stopping bait casting on the central platform layer, the bait casting areas are concentrated above the bottom platform layer, a small amount of bait casting is carried out above the second platform layer, the central platform layer and the first platform layer are not bait casting, and at the moment, the aeration device is opened, and the bottom platform layer has large stichopus density due to the fact that the bottom platform area collects the stichopus japonicus of the central platform layer, the first platform layer and the second platform layer, and the aeration state should be kept for 24 hours; when the stichopus japonicus enters the summer sleep, the bait feeding is completely stopped; when summer is finished, the water temperature of the bottom platform layer is firstly reduced to a temperature suitable for growth of the stichopus japonicus, the stichopus japonicus climbs out of the fish reef, summer sleeping is finished, bait casting is resumed on the bottom platform layer, the stichopus japonicus is induced to climb out of the bottom platform layer and the second platform layer through bait casting along with the reduction of the water temperatures of the first platform layer and the central platform layer to the temperature suitable for growth of the stichopus japonicus, the stichopus japonicus enters the central platform layer and the first platform layer, bait casting above the bottom platform layer is gradually reduced, bait casting of the central platform layer, the first platform layer and the second platform layer is gradually increased, and the stichopus japonicus is induced to climb out of the bottom platform layer; stopping feeding the bottom platform layer until the stichopus japonicus spends summer.

Compared with the prior art, the invention has the beneficial effects that:

the first platform layer and the second platform layer are arranged between the central platform layer and the bottom platform layer, when the stichopus japonicus is cultured in summer, the stichopus japonicus gradually enters the bottom platform layer from the central platform layer through bait casting induction, the buffer area has good guiding effect on the stichopus japonicus with weak activity, the stichopus japonicus gradually enters the bottom platform layer suitable for growth through the gradual reduction induction of water temperature while the bait induction is carried out, the oxygenation equipment is arranged on the bottom platform layer, meanwhile, bait casting is increased, and the normal growth of the stichopus japonicus in summer is guaranteed. When summer is finished and the water temperature on the central platform layer is suitable for the growth of the stichopus japonicus, the stichopus japonicus leaves the bottom platform layer and enters the central platform layer more suitable for growth through bait induction. The invention shortens the sleeping time of the stichopus japonicus and improves the speed of the stichopus japonicus exiting the pond.
