Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0020] Such as figure 1 , figure 2 and image 3 As shown, the present invention provides a kind of monitoring method of cage fish culture large-scale fish, comprises the following steps: step 1, provides a net cage 1, is formed with slide respectively on the upper edge of two opposite side walls of this net cage 1. Rail 2, the upper part of a mesh body 4 is rotatably provided with a rotating shaft, and the two ends of this rotating shaft are respectively provided with pulley 3, and a motor is connected to described rotating shaft, and each pulley 3 can be arranged on the mode that slides along described slide rail. on a slide rail 2, so that the net body is movably arranged in the net box; the cross-sectional area of ​​the net box in the direction perpendicular to the movi...

Abstract

The invention discloses a method for monitoring large fishes cultured in a net cage. The method comprises the steps that firstly, the net cage is provided, and a net body is provided with a plurality of round meshes which are evenly distributed, wherein eight to ten pressure sensor patches are arranged on the circumferential edge of each mesh; secondly, a motor drives the net body to move to the other side from one side of the net cage at a constant speed, in the moving process of the net body, when five or more pressure sensor patches of each mesh generate pressure signals at the same time, a counter counts one and sends a counting signal to a processor, and when the net body moves to the other side of the net cage, the number of counting signals received by the processor is used as the number of large fishes in the net cage. When the net body moves, fishes are forced to pass through the meshes, when fishes grow to have certain body sizes, multiple pressure sensors are triggered, the number of the counting signals of the processor is used as the number of large fishes in the net cage, and therefore monitoring and counting of large fishes are achieved.

Description

technical field [0001] The invention relates to a breeding method, in particular to a method for monitoring large-scale fish cultured in cages. Background technique [0002] Since 1973, after the introduction of cage fish farming technology in our country, by the 1980s, there were more than 500 hectares of cage culture on large water surfaces such as lakes and reservoirs, and the average fish production per hectare was about 300 tons. . Since the 1990s, the cage fish farming industry has shown a trend of vigorous development. The scale and density of cage farming have continued to increase, and the aquaculture area and production have increased rapidly. [0003] The fish can be fished out when it grows to a certain size, but in the current cage fish culture technology, there is no suitable way to monitor large fish. Contents of the invention [0004] Aiming at the above-mentioned technical problems, the present invention designs and develops a monitoring method for large...
