Embodiment 1

[0033] 70 24-month-old clam scallops cultured in Qingdao sea area were taken to measure the pulling force index, and the quality traits of scallops were quickly evaluated based on the pulling 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 and keep them for more than 10 minutes;

[0035] 2) Adjust the upper and lower clips of the tension measuring device to a distance of 0.75cm, set the reading of the digital display 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 connected successfully;

[0036] 3) Take the Chlamys farreri out of the seawater, keep its shell open, and quickly place it on the adjusted tension measuring device. After the scallop double shells are stably clamped by the ...

Embodiment 2

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

[0067] Specific steps are as follows:

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

[0069] (2) Adjust the upper and lower clips of the tension measuring device to a distance of 0.75cm, set the reading of the digital display 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, conduct an online test through the data analysis software, and confirm that the device and the software are connected successfully;

[0070] (3) Take the Chlamys farreri out of the seawater, keep its shell open, and quickly place it on the adjusted tension measuring device. After the scallop double shel...

Abstract

The invention establishes a method for rapidly evaluating the quality characters of scallops based on a tension index. According to the method, the quality character of a scallop is rapidly evaluated according to the size of the tension of the adductor muscle of the scallop. By combining standardized measurement of the tension of the adductor muscles of scallops with a model for estimating the glycogen content through the tension index, a novel method for rapidly evaluating the quality characters of scallops is established, and a reliable technical means is provided for accurately evaluating the quality characters of scallops in the breeding work. According to the method, nondestructive tension detection is performed on scallops, and the obtained scallop tension index is used as a basis for rapidly evaluating the quality of scallops. Compared with a traditional scallop glycogen detection method, the method has the characteristics of high efficiency, simplicity, convenience, no damage and the like, and the scallop tension is used as an index for quickly evaluating the scallop quality for the first time. By adopting the method, technical support can be provided for improvement of quality characters of scallops.

Description

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