Embodiment approach

[0045] The first preferred embodiment: a fry screening system, such as figure 1 As shown, comprise screening pond 100, be provided with the screening device 10 that fry size classification is arranged on screening pond 100, screening device 10 comprises louver type grid mechanism 11, power source 12 and connecting mechanism 13, louver type grid mechanism 11 is connected by Mechanism 13 is fixed in the breeding pond 101, and the louver-type grid mechanism 11 includes a number of evenly arranged blades 102. The blade 102 is provided with a support shaft 103 supporting the blade 102. The support shaft 103 is connected with the blade 102 in rotation, and the support shaft 103 is two The end is provided with a frame 104, the support shaft 103 is fixedly connected with the frame 104, the frame 104 is connected with the sliding fit of the connecting mechanism 13, the primary louver grid 106 is arranged between the screening pool 100 and the emergence pool 607, and the primary louver g...

Embodiment 2

[0053] A method for fry screening, comprising the following steps:

[0054] a, Fry input: After the fry are cultivated in the cultivation pool 502 for fifteen to twenty days, most of the fry have grown to the emergence stage, and it is necessary to filter out the fry that reach the emergence standard, and open the input switch 503. Due to the height difference and the gravitational force, the fry Entering the screening pond 100 from the input pipe 501, the screening pond 100 needs to be cleaned and disinfected first, and water is first injected into the screening pond 100 to prevent the fish fry imported by the input pipe 501 from directly colliding with the bottom of the screening pond. Filtration with gauze and silk, the water depth is 0.1-0.2 meters.

[0055] b. Disinfection of fish fry: In order to prevent the fry from being invaded by germs, it is necessary to use a disinfection device 20 to disinfect the fry. Take 12 grams to 13 grams of dried tobacco leaves per liter of...

Abstract

The invention discloses a fish fry screening system and method, relates to the field of aquaculture. The fish fry screening system and method are characterized in that the set of fish fry screening system enabling water flow to drive a shutter type grid under the action of a peripheral pump is set for fish fry screening, and the fish fry screening method through the fish fry screening system comprises the steps of a, fish fry input, b, fish fry disinfection, c, fish fry screening, d, fish fry output, e, fish fry cultivation and f, secondary screening. The fish fry screening system and method have the technical effects that fish fries pass over a screening device to be screened through the water flow and different fluorescent lamp in a guide type, the screening device does not need to be manually moved for screening, screened fishes do not need to be fished up, the fish fries are automatically output, damage to the fish fries is small, oxygen deficit cannot be caused, and the survival rate is high.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a fry screening system and method thereof. Background technique [0002] Before fry breeding, it is necessary to screen the fry, and separate the fry of different sizes to avoid the situation where big fish plunder small fish and compete with each other. [0003] The screening process of the existing fry screening device is cumbersome, and it is necessary to manually move the screening device for screening, which will cause great friction damage to the outer scales of the fry, resulting in a low survival rate of the fry. , the survival rate of fry will be reduced. Contents of the invention [0004] The object of the present invention is to provide a fish fry screening system and method thereof, which has the advantages of no need to pick up the fish, no need to move the screening device, the fish fry can be screened by different fluorescent lamps and water flow guided self-swimming ...
