Problems solved by technology

However, the adductor muscle is wrapped in a hard shell. Compared with body weight, body size and other traits that can be measured without damage, the measurement of the adductor muscle requires dissection, and the workload is heavy. More importantly, the measured shellfish cannot survive. , resulting in the inability of individuals with high muscle mass to be used for breeding, which has become the main technical bottleneck for shellfish muscle growth, quality research, and high-muscle shellfish breeding

Embodiment 1

[0025] A method for in vivo non-destructive detection of shellfish muscle, the steps are as follows:

[0026] (1) Take scallops with good activity (the mantle stretches naturally, and the soft body does not shrink significantly), and after cleaning the fouling organisms on the surface of the shell, place the individual to be tested in a tank filled with seawater (4°C-15°C). in the container;

[0027] (2) Install the X-ray image acquisition device (manufacturer: Shenzhen Tianhe Times Electronic Equipment Co., Ltd. AT2310), specifically the X-ray source, X-ray panel acquisition instrument (including X-ray control box) and the X-ray acquisition device installed The PC side of the system software is connected together, such as figure 1 shown;

[0028] (3) Align the emission source port of the X-ray source with the "+" position (center position) of the X-ray panel collector, and the distance between the X-ray emission source and the panel of the collector is 1.2m-1.5m;

[0029] ...

Embodiment 2

[0037] According to the following two settings, the X-ray image acquisition device is used to collect the X-ray image of the same scallop. The results are as follows: Figure 5 As shown (the first setting is on the left, the second setting is on the right). It can be seen from the figure that when the shell imaging effect is similar, the image of the adductor muscle in the image obtained by the first setting is clear, which can detect the size information of the adductor muscle more accurately.

[0038] First setting:

[0039] Radiation source parameter setting: high voltage value 120 (KV), current 800uA;

[0040] X-ray panel acquisition instrument parameter setting: select the software starting mode, set according to the following parameters: ExposureTime 1500ms (irradiation time 1500s), Delay Time 1000ms (delay time 1000s), Integrate Time 100ms (integration time 100ms), double exposure (secondary exposure) ;Click Apply to confirm the implementation of this parameter.

[004...

Embodiment 3

[0045] A total of 232 Ezo scallops of different ages and different sizes (the height of the first-year-old shell about 3cm, and the height of the third-year-old shell about 9cm) were selected, and a total of 232 pieces were used. The cross-sectional area of ​​the adductor muscle was measured and counted by the method described in Example 1. The weight of the adductor muscle was measured in anatomically related scallops, and the correlation between the cross-sectional area of ​​the scallops and the weight of the real meat column was calculated (Table 1). Significant correlation indicates that the area data of the scallop adductor muscle obtained under the non-destructive condition by using the present invention can be used to reflect the real weight, thereby indicating that the cross-sectional area can be used as a standard for shellfish species selection.

Abstract

The invention provides a method for rapid living body nondestructive detection and evaluation of shellfish muscle mass, which relates to the technical field of shellfish muscle research and breeding.The method comprises the steps of setting of an X-ray radioactive source and digital imaging parameters, muscle living body identification and cross-sectional area measurement. According to the method, a clear image and accurate measurement data of the cross section of the shellfish muscle can be obtained under a nondestructive condition, the muscle mass is evaluated, the problem that a measured individual cannot survive and cannot be used as a breeding parent due to the fact that a traditional shellfish muscle property measuring method needs dissection is solved, research on living shellfishmuscle properties becomes possible, and the efficiency of high-muscle mass shellfish fine breed cultivation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shellfish muscle research and breeding, in particular to a method for measuring the cross-sectional area of ​​adductor muscle by using X-rays to characterize shellfish muscle mass. Background technique [0002] my country's marine aquaculture production ranks first in the world, of which shellfish aquaculture production accounts for more than 70%. Shellfish aquaculture is of great significance to increasing farmers' income and promoting export earnings. The healthy development of the aquaculture industry depends on the continuous innovation and improvement of germplasm, and the cultivation of improved shellfish species has always been a hot spot in the industry. Many shellfish such as scallops and scallops have well-developed muscles (additive muscles), and are delicious and nutritious, and are widely loved by consumers from all over the world. At the same time, the dried products of the adductor muscle ...
