Problems solved by technology

Not only is it time-consuming and labor-intensive, but the collection of the growth traits is carried out when the fish is out of water. During the operation, repeated contact with the fish is required, which causes a strong stress response to the measured fish, so that some Measuring the phenomenon of stop feeding or even death in the living body, which affects the growth and survival of fish

Embodiment Construction

[0016] The technical solutions of the present invention will be further explained by the following examples, but the protection scope of the present invention is not limited in any form by the examples.

[0017] A device for quickly measuring the growth traits of fish, such as figure 1 As shown, it includes a measuring platform, a camera 1 and a bracket. The measuring platform includes a measuring platform 2, a surrounding surface 3 of the measuring platform, a weighing device, a display screen 4 and a keyboard 5, and there are two crossed measuring lines 6 on the measuring platform. The weighing device is located below the measuring platform 2, and the display screen 4 is located on the circumference of the measuring platform. There is a keyboard 5 beside the display screen 4. The weighing device can accurately weigh the weight of the object on the measuring platform and display it on the display screen. The keyboard has A button to reset the numbers on the display screen to ...

Abstract

The invention provides a fish body growth character fast measuring device and a measuring method, and belongs to the field of aquaculture devices. When the device is used for measuring fish bodies, only few steps are needed. Besides, collecting of growth characters of one fish body can be finished in a short time, repeated contact with the fish body can be prevented, and stress responses caused by data collecting are reduced. A support on a measuring table of the device guarantees that a camera is kept to be fixed on the same height during growth data collecting of the fish bodies. Meanwhile, the face of the measuring table and a lens of the camera are provided with table face scales and lens scales respectively to guarantee that the camera is basically vertical to the fish bodies to be measured, and measuring errors are reduced.

Description

technical field [0001] The invention belongs to the field of aquaculture devices, and in particular relates to a device and a measuring method for rapidly measuring the growth characteristics of fish bodies. Background technique [0002] In the process of fish breeding, it is necessary to measure the growth traits of fish regularly, such as body length, total length, head length, weight, tail peduncle length and other growth indicators, in order to evaluate the situation of breeding, which is the next step Formulate breeding and breeding plans to provide reference. The existing main measurement method is to use measuring tools to measure multiple times in steps when the fish is out of water. Usually, first use weighing tools to weigh the body weight of the fish, and then use measuring tools such as rulers or vernier calipers to measure Body length, overall length, head length, tail peduncle length, etc., a fish needs at least 3 steps to measure to complete the measurement. ...
