Embodiment

[0025] like figure 1 As shown, the device is composed of a water tank 1, a partition 3, a screen 2, and water inlet and outlet pipes. The water tank 1 is divided into three relatively independent breeding tanks 11 by a partition plate 3 and a screen cloth 2 . The tank 1 and the partition 3 are connected as a whole. The tank 1 and the partition 3 are made of epoxy resin or concrete. The height of the partition 3 is 1 / 3 to 1 / 2 of the height of the tank 11. Card slot 4 is set on the tank wall. The screen 2 is made of stainless steel (or nylon material) nets and metal (or plastic material) frames of different mesh sizes. The screen 2 is closely connected with the partition 3 through the slot 4 embedded in the wall of the tank 1. Stand on the partition 3. 3 relatively independent breeding tanks 11 are installed with independent water inlet and outlet pipes, and the water inlet and outlet pipes are all made of PE pipes and the like. Water inlet pipe 5 installs water inlet valve ...

Abstract

The invention discloses a culturing device with a function of fish screening. The device comprises a water tank, the inner bottom of the water tank is provided with a plurality of partition plates arranged at intervals, clamping grooves are formed in the upper portions of the two sides of each partition plate, and each clamping groove is internally provided with a screen in a clamping mode. The water tank is divided into a plurality of independent culturing tanks by the partition plates and the screens. A water draining hole is formed in the middle of the bottom end of each culturing tank, the sieve numbers of the two adjacent screens are different, and the sieve numbers of all the screens are decreased progressively in sequence from large to small. The water tank is further connected with a water inlet pipe assembly and a water draining pipe assembly. According to the culturing device, the water tank is divided into a plurality of the independent culturing tanks by the partition plates and the screens, sufficient activity space can be provided for small individual fingerlings, and the phenomena of attack and cannibalism among the individuals of the fingerlings can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture device with the function of sifting fish. Background technique [0002] During the fry breeding process, due to factors such as intraspecific competition, uneven bait feeding, and insufficient bait, fry often have different sizes. On the one hand, large individual differences in fry may lead to cannibalism, which in turn leads to adverse effects such as low survival rate of fry cultivation. On the other hand, when fish are released, it is often required that the fish species reach a certain size, and the fry of different sizes will undoubtedly increase the burden of picking and separating the fry. If the picking time is too long, it will cause further damage to the fry. Avoiding the different sizes of fish species in the fry breeding process and quickly screening the required size fish species have important practical significance for the smooth development of...
