Embodiment 1

[0027] Embodiment 1: Penaeus japonicus culture high level pond

[0028] Such as figure 1 Shown, a kind of penaeus japonicus culture high position pond, comprises pond body 1, and this pond body 1 is square (about 1.3 mus, and its length, width and depth are respectively 35m, 25m and 2.2m, and the slope of the pond wall is about 60°) , the bottom of the pool and its surroundings are covered by cement irrigation or plastic film. In this pool body 1, an activity area 2, a bait feeding area 3 and a waterwheel type aerator (not shown) are set. The bait feeding area 3 is ring-shaped, and its width is 1.5 ~2m, its width is 2m in this embodiment. Among them, the activity area 2 is set in the center of the pool body 1, the bait throwing area 3 is surrounded by the activity area 2 around the activity area 2, and there are two water wheel aerators arranged on the opposite side of the pool body 1. Corner, and the waterwheel type aerator used in the embodiment is the waterwheel type aera...

Embodiment 2

[0034] Embodiment 2: Penaeus japonicus cultivation method

[0035] This culture method comprises the following steps: first in this high level pond, throw in Penaeus japonicus (purchased from the local prawn nursery in Zhoushan, the same below), the culture density of Penaeus japonicus is 5w / acre, according to the presence of Penaeus japonicus in the present embodiment The habit of feeding at night, so the feeding time is arranged at 18:30, 24:00 and 4:00.

[0036] 20 minutes before feeding, turn off the waterwheel type aerator to stop the water body from flowing, so as to prevent the water flow from bringing the feed into the sanding area after feeding. After feeding, it can be observed that a large number of Penaeus japonicus are concentrated in the feeding area for feeding by light irradiation; after the feeding is completed, most of the shrimp are attached to the slope protection around the pond. The channel excretes food quickly, so most of the feces will also be concent...

Embodiment 3

[0038] Embodiment 3: Penaeus japonicus cultivation method

[0039] This culture method comprises the following steps: first in this high position pond, puts Penaeus japonicus in, and the culture density of Penaeus japonicus is 7w / mu, in the present embodiment, according to the habit of asking for bait at night, Penaeus japonicus has, so feeding time is arranged in 18:00, 23:30 and 3:30.

[0040] 30 minutes before feeding, turn off the waterwheel type aerator to stop the water flow and prevent the water flow from bringing the feed into the sand area after feeding. After feeding, it can be observed that a large number of Penaeus japonicus are concentrated in the feeding area for feeding by light irradiation; after the feeding is completed, most of the shrimp are attached to the slope protection around the pond. The channel excretes food quickly, so most of the feces will also be concentrated in the feeding area. After 2 hours of baiting, the waterwheel aerator is turned on acc...

Abstract

The invention relates to sand laying devices which are used for being placed at the bottom of a high-level-pond for penaeus japonicus breeding. Each sand laying device comprises a bracket body, each bracket body comprises a tray and supporting pillars which are arranged at the bottom of the corresponding tray and used for supporting the corresponding tray, and a dirt discharging gap allowing residual feed and excreta to be discharged is formed between the bottom face of each tray and the bottom of the high-level pond; the invention further relates to the high-level-pond, adopting the sand laying devices, for penaeus japonicus breeding and a penaeus japonicus breeding method adopting the high-level pond. The sand laying devices are simple in structure and have good mobility, and besides accumulation of the residual feed and excreta on a sand laying layer can be avoided; the high-level pond is internally provided with a feed feeding area for feeding of penaeus japonicus and an activity area allowing the penaeus japonicus to be hidden in sand, residues of the residual feed and excreta on the sand layer are directly reduced, and a good growth environment is provided for growth of the penaeus japonicus; the breeding method provides a good growth environment for growth of the penaeus japonicus, and diseases of the penaeus japonicus in the breeding process are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high level pond for cultivating Penaeus japonicus and a cultivating method thereof. Background technique [0002] Penaeus japonicus, also known as Penaeus japonicus, has a wide market prospect because of its rich nutrition and high economic value. It is one of the important marine cultured shrimp species in my country. Shrimp pond high-level ponds refer to the ponds where shrimps are raised on the seashore, where the terrain is higher than sea level, and seawater is pumped to raise shrimps. Habits, developed a new model suitable for the culture of Penaeus japonicus - high level pond sand intensive culture model. At present, this breeding mode has been gradually promoted and applied in Hainan, Guangdong, Guangxi, Fujian, Zhejiang and other places in my country. The maximum yield per mu can reach more than 500kg, and the economic benefits are remarkable. [0003] After year...
