Embodiment 1

[0043] A method for discriminating diseases of crabs, first obtain the standard spectrum of healthy crabs, and adopt conventional experimental methods (a number of crabs can be taken to carry out parallel experiments, half of which are carried out for biological measurement, and half for the measurement of sound power spectrum, if the batch of crabs determined by biological experiments If it is a healthy crab, it can be considered that the sound power spectrum measured by this batch of crabs is a healthy standard spectrum) to determine healthy crabs, and use the same detection method as the crab sample to be tested below to obtain a healthy crab standard spectrum, and enter it into the computer in advance as a basis for discrimination .

[0044] Secondly, the sound power spectrum of the crab sample to be tested was determined respectively according to the following procedures:

[0045] 1) Take n crab samples from the pond, remove the attached water, and put them into the crab ...

example 1

[0055] Determination of the power spectrum of crab-like vocalizations.

[0056] Choose a quiet room free of interference from fixed sound sources, follow the figure 1 Connect the acoustic measurement system, including: crab sample 1, base 2, sample container 3, static pressure rod 4, sensor waterproof cover 5, sensor 6, signal transmission line 7, sensor fixing frame 8, temperature and humidity meter 9, precision sound level measurement instrument 10, spectrum analyzer 12. Turn on the machine, adjust the range of the precision sound level measuring instrument to an altitude of 60 decibels, select the spectrum analysis measurement parameters (sampling frequency 200KHz, spectrum range 0-10kHz, resolution 0.1Hz, measurement time 6 seconds, first measure the background sound power spectrum.

[0057] Randomly fish 3 crab samples from Pond A (1 # ,2 # 、3 # ), get rid of the attached water, put it into the sample container 3, adjust the distance of the sonic sensor probe 6 close ...

example 2

[0066] Determination of power spectrum of crab-like vocalization

[0067] To select a quiet room, follow the figure 1 Connect the acoustic measurement system, same as Example 1. Turn on the machine, adjust the range of the precision sound level measuring instrument to an altitude of 45 decibels, select the spectrum analysis measurement parameters (sampling frequency 200KHz, spectrum range 0-10kHz, resolution 0.1Hz, measurement time 10 seconds, first measure the background sound power spectrum.

[0068] 5 crab samples were randomly picked from pond B (1 # ,2 # 、3 # 、4 # 、5 # ), get rid of the attached water, put it into the sample container (3), adjust the distance of the sonic sensor probe (6) close to the crab sample, lightly touch the crab body with the static pressure rod (4), and keep it for 10 seconds to make the crab naturally quiet and dormant; Start the timing measurement after staying for 10 seconds; measure each crab sample 5 times; measure the environmental po...

Abstract

The invention discloses a crab disease judging method and a diagnosis device. The crab disease judging method is characterized by including steps of detecting sound production frequency spectrums of ahealth crab and a sick crab; analyzing the sound production frequency spectrum structure and every part proportional relationship, shape and number of sharp peak; after comparing with the health standard spectrum, diagnosing the health status and disease type of crab sample. The method avoids the shortcomings of big subjective element of an artificial observation method, need of experimental place and ultra-clean workbench of microorganism identifying method, and long consumed time. The crab disease judging method is applicable to study crab pathology and physiological behavior characteristics in universities and colleges, and scientific research institution; administrative departments can publish the aquatic product disaster situation timely. For a large culture pond, the method can be applied to set up a set of full-day system for monitoring health status of crabs, thus the crab disease can be found in advance, the pond is handled timely, and happening of large scale culture diseaseis prevented.

Description

technical field [0001] The invention relates to an aquatic product cultivation technology, in particular to a prediction technology capable of judging in advance whether crabs are sick or not and the types of diseases that are susceptible to or will suffer from before the crabs develop a disease, specifically a crab Disease discrimination method and diagnosis device. Background technique [0002] Crab is one of the important species of freshwater aquaculture, and it is a delicacy in autumn and winter. In recent years, with the continuous expansion of the scale of farming, the degree of intensification has increased significantly, accompanied by the emergence of various diseases, which seriously plagued the healthy development of the farming industry. Crab disease has a high incidence rate and a sudden onset. Once the disease spreads, it is difficult to control it with drugs. If it occurs in July-August, farmers will lose their money. According to investigations, bacterial ...
