Description

Tilapia grading cultivation device

technical field

The utility model belongs to the technical field of aquaculture, in particular to a tilapia grading cultivation device.

Background technique

Tilapia is a small and medium-sized fish, which belongs to warm-water bottom fish. It can grow in water at 12-40°C, and its optimum growth temperature is 24-32°C. Now tilapia is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and is known as one of the main sources of animal protein in the future. Native to Africa, it is a tropical fish belonging to the family Cichlidae, similar to perch. The feeding method of tilapia fry is ad libitum, and it is necessary to test the water before releasing the tilapia fry. Farmers usually use plastic pots or foam boxes to complete the water test process. During the water test process, plastic pots or foam boxes Floating in the breeding pond, its stability is difficult to control, which will affect the water testing operation.

The structure of the traditional culture pond is simple, which cannot meet the needs of tilapia culture. After the tilapia is raised, it needs to be reared in separate ponds with the increase of tilapia individuals. The traditional method of dividing ponds is only quantitatively divided. , and the sub-pond operation is complicated, time-consuming and labor-intensive. In the tilapia culture process, there will be continuous rainy days, and the phenomenon of flooding the pond will appear. The traditional drainage method is not efficient, and the sewage is prone to reverse flow, causing water pollution in the culture pond.

Therefore, it is necessary to propose a culture pond with good water drainage effect and suitable for tilapia growth, which is convenient for hierarchical breeding and improves the yield of tilapia.

detailed description

In order to make the purpose, technical solutions and beneficial effects of the utility model more clear, the preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of technical personnel.

As shown in Fig. 1-3, described tilapia grading cultivation device mainly comprises seedling pond 1, separate raising pond 2, test water pond 3, L-shaped drainage pipe 7, screen 8, dividing plate 9, drainage ditch 10, Column 11, protection embankment 17. The lower part of the test water pool 3 communicates with the top of the nursery pond 1 through a pipeline, and the pipeline is provided with a fish inlet valve 4 to control the fish fry after water testing to enter the nursery pond 1. Nursery pond 1 and separate raising pond 2 junctions are provided with two upright columns 11, and two upright columns 11 are provided with screen cloth 8 near nursery pond 1 side, can separate the tilapia of different sizes by screen cloth 8, two A slot 12 is longitudinally provided on the upright post 11, and the partition 9 is movably arranged in the slot 12, and the separation operation can be carried out by removing the partition 9. Both the nursery pond 1 and the separate culture pond 2 are equipped with an aerator 6 to increase the dissolved oxygen in the pool water, and the inner wall is provided with a detachable material table 5, and the water levels in the nursery pond 1 and the separate culture pond 2 are the same , the feeding table 5 was set at 15 cm below the water level, and the feeding method of ad libitum was adopted. The bait was placed on the feeding table 5 and fed 3 times a day.

A protection dike 17 is provided between the subculture and the drainage ditch, and one end of the L-shaped drainage pipe inlet 13 is arranged in the nursery pond 1 and the separate cultivation pond 2, and one end of the water outlet 14 of the L-shaped drainage pipe passes through the protection dike 17 Set in the drainage ditch 10, the L-shaped drainage pipe 7 in the nursery pond 1 passes through the column 11 and is arranged on both sides of the nursery pond 1, thus completing the setting of the L-shaped drainage pipe 11. The water inlet 13 of the L-shaped drainage pipe is provided with a sealing ring 16, and a movable hollow floating ball 15 is arranged in the pipe body under the sealing ring 16, and the spherical edge of the hollow floating ball 15 is connected with the sealing ring 16. When the water level in the nursery pond 1 and the separation pond 2 was higher than the water level of the drainage ditch 10, the pool water entered the L-shaped drainage pipe 7 from the L-shaped drainage pipe inlet 14, and then was discharged into the drainage from the L-shaped drainage pipe outlet 14 In the ditch 10, when the water level of the drainage ditch 10 was higher than the water level in the nursery pond 1 and the separate breeding pond 2, the water in the drainage ditch 10 flowed backwards from the outlet 14 of the L-shaped drainage pipe to push the hollow float in the L-shaped drainage pipe 7. The ball 15 moves upwards until the hollow floating ball 15 fits the sealing ring 16, preventing the water in the drainage ditch 10 from entering the nursery pond 1 and the separate culture pond 2, thereby achieving the effect of preventing backflow.
