Embodiment 1

[0033] Take 70 24-month-old scallops cultivated in Qingdao sea area to measure the tensile force index, and quickly evaluate the quality traits of scallops based on the tensile force index. The specific steps are as follows:

[0034] 1) Place 70 24-month-old scallops to be tested in an aerated circulating seawater system for more than 10 minutes;

[0035] 2) Adjust the upper and lower clips of the tension measuring device to a distance of 0.75cm, adjust the reading of the digital tension meter to zero, adjust the unit to N (1N=0.98kg), and adjust the sampling rate to 1000Hz (5 data / second), Connect the serial port, and conduct an online test through the data analysis software to confirm that the device and the software are successfully connected;

[0036] 3) Take the scallops out of the seawater, keep their shells open, and quickly place them on the debugged tension measuring device. After the double shells of the scallops are stably clamped between the upper and lower clips, ...

Embodiment 2

[0066] Using the method of Example 1 of the present invention, 30 24-month-old scallops cultivated in Qingdao sea area were tested to verify the accuracy and reliability of the method of the present invention.

[0067] Specific steps are as follows:

[0068] (1) Place 30 24-month-old scallops to be tested in an aerated circulating seawater system for more than 10 minutes;

[0069] (2) Adjust the upper and lower clips of the tension measuring device to a distance of 0.75cm, adjust the reading of the digital tension meter to zero, adjust the unit to N (1N=0.98kg), and adjust the sampling rate to 1000Hz (5 data / second) , connect the serial port, and conduct an online test through the data analysis software to confirm that the device and the software are successfully connected;

[0070] (3) Take the scallop out of the seawater, keep its shell open, and quickly place it on the debugged tensile force measuring device. After the double shell of the scallop is stably clamped between ...

Abstract

The invention establishes a method for quickly evaluating the quality traits of scallops based on the tension index, and uses the pulling force of the scallop adductor muscle to quickly evaluate the quality traits of the scallops. The present invention establishes a new method for rapid evaluation of scallop quality traits through the standardized measurement of scallop adductor muscle pulling force, combined with the pulling force index to estimate the glycogen content model, and provides a reliable technology for the accurate evaluation of quality traits in scallop breeding. means. The invention detects the pulling force without damage to the scallop, and uses the obtained scallop pulling force index as a basis for quickly evaluating the quality of the scallop. Compared with the traditional scallop glycogen detection method, the method of the present invention has the characteristics of high efficiency, simplicity, and no damage, and it is the first time that the scallop pulling force is used as an index for quickly evaluating the quality of scallops. This method can provide technical support for the improvement of scallop quality traits.

Description

technical field [0001] The invention belongs to the technical field of marine biology, and in particular relates to a method for rapidly evaluating the quality traits of scallops based on a tensile force index. Background technique [0002] As one of the important marine aquaculture shellfish in my country, scallops account for more than 80% of the global annual aquaculture production of scallops (China Fishery News Statistics 2020). The dried product of the adductor muscle of scallop is called scallop, commonly known as dried scallop. It is one of the eight treasures of seafood. It is rich in protein, carbohydrates, unsaturated fatty acids, trace elements and other nutrients. It tastes delicious and is widely consumed at home and abroad. the favorite. With the improvement of domestic consumption level, consumer demand for high-quality scallop products continues to increase. However, my country's scallop industry has the problems of lack of high-end products and low propor...
