Embodiment Construction

[0018] Such as figure 1 , figure 2 with image 3 As shown, the present invention includes a water tank 1 without a top cover. The water tank 1 is a rectangular parallelepiped made of plexiglass with a size of 2.0×0.3×0.2 m. One end of the water tank 1 is open, and the other end of the water tank 1 is closed. The open end of the water tank 1 is installed with a block 5, and three movable card slots 9 are installed on the side wall of the water tank 1, and the distance from the closed end of the water tank is 0.3m, 0.7m and 1.2. m. Insert the fish trough 2 into the three movable card slots 9 respectively. The three fish troughs 2 divide the water trough 1 into an area of ​​0.09 m. 2 , 0.12 m 2 , 0.15 m 2 And 0.3 m 2 In the four areas, the fish rack 2 is composed of multiple parallel blades 8 and rotating shafts. The gap between the blades is adjustable, similar to the shutter structure. According to the order from near to far away from the closed end of the tank 1, three The gap...

Abstract

The invention relates to a screening device for fishes of particular specification. The screening device comprises a half-headed water tank, wherein one end of the water tank is open, the other end of the water tank is closed, the side wall of the water tank is provided with multiple movable clamping slots, the open end of the water tank is provided with a blocking net, at least one fish blocking corral is mounted in the water tank by virtue of the movable clamping slots and the water tank is divided into multiple regions, at least one baffle is matched with the movable clamping slots, the closed end of the water tank is provided with a water tank water inlet hole, the baffle is provided with a baffle water inlet hole, and a water inlet pipe communicated with the water pump is matched with the water tank water inlet hole and the baffle water inlet hole. The screening device for the fishes of particular specification disclosed by the invention can be used for rapidly screening and separating individual fishes of particular specification by utilizing the stream against characteristic of the fishes, the defects of the existing screening method are overcome, time and effort are saved, the screening device is simple in structure, easy in operation and high in efficiency, and the economic benefit is improved.

Description

Technical field [0001] The invention relates to a fish screening device, in particular to a device for screening fish of a specific size. Background technique [0002] In the practice of fishery production and scientific research, there is a need to select fish of specific specifications. Specifically, such as the division of fish seedlings of different sizes and cultured individuals, batch sales, and nutritional, toxicological or behavioral tests of fish, it is necessary to select fish of a certain size. [0003] At present, from fish schools of different individual sizes, there are two main methods commonly used to screen individuals of a certain size: The first method is to screen seedlings, using a seedling sieve (a sieve made of bamboo strips). After restricting the fish’s moving space, artificially scoop the water and splash it against the seedling sieve to create a water flow. Use the top flow characteristics of the fish to guide the smaller individuals from the sieve gap, ...
