Embodiment Construction

[0018] 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.

[0019] like figure 1 As shown, the present invention provides a kind of weight detection method of net cage fish culture, comprising:

[0020] Step 1, a net cage 2 is provided, the net cage is conical, an ultrasonic detector 1 is installed on the top of the net cage, the detection area of ​​the ultrasonic detector 1 is conical, and the detection area of ​​the ultrasonic detector covers the net In the inner space of the box 2, the ultrasonic detector is communicatively connected with a processor.

[0021] Step 2, establish a standard database in a memory in advance, store a plurality of spindle-shaped standard images in advance in the database, each standard image corresponds to fish of different sizes, the length of each standard image and the widest point of the standard im...

Abstract

The invention discloses a cage fish-farming weight detection method. The method comprises the steps that a conical cage is provided, and the detection area of an ultrasonic detector covers the internal space of the cage; a standard database is established in a memory in advance; a number of fusiform standard images are pre-stored in the database, and the length of each standard image and the widest width of the standard image are respectively corresponding to the widest width and the length of a fish; the weight of the fish is recorded to the standard image as standard weight; information acquired by an ultrasonic detector is processed into a detection image through a processor, wherein the detection image comprises a number of image blocks representing the fish; the processor individually compares each image block with the standard images; and if the length and the widest width of an image block match a standard image, the standard weight is used as the detection weight of the fish represented by the image block. According to the invention, the total weight of fishes in the cage can be conveniently detected.

Description

technical field [0001] The invention relates to a breeding method, in particular to a method for detecting the weight of fish cultured in a net cage. 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] During the breeding process, the breeders are very concerned about the growth of the fish, especially the weight. When the total weight meets the requirements, it means that the growth of the fish in the current segment is good and the feed is reasonable. But there is no method for measuring the total weight ...
