Abstract

The invention relates to a method of assessing a shellfish health condition by adopting a dynamometer, comprising the following steps: selecting a proper shellfish with a certain specification; performing treatment on the shellfish before shell opening; opening the shell of the shellfish by adopting a shell opener; connecting various assemblies of the LH-F490 portable dynamometer; starting the LH-F490 portable dynamometer and testing, i.e., setting parameters after starting, pressing a zero clearing key for zero clearing, and testing whether the display pressure change of a displayer exists or not, wherein a tension sensor is selected as a clamp of the LH-F490 portable dynamometer, displayed data N1 is recorded, a byssus of the shellfish is taken out, vertically penetrates through a test ring, and is pulled apart, and displayed data N2 is recorded; an occlusal force sensor is selected as the clamp of the LH-F490 portable dynamometer, displayed data N3 is recorded, a contact of the clamp is clamped in a shell, and displayed data N4 is recorded; putting the tested shellfish in another identical water environment for continuously culturing. The method has the advantages that high speed and convenience are realized, mechanical damage conditions are reduced, and the method can be widely applied to a shellfish culture process.

Description

technical field [0001] The invention relates to the technical field of shellfish health status, in particular to a method for evaluating shellfish health status by using a dynamometer. Background technique [0002] With the development of society, the water quality pollution caused by modernization and the expansion of aquaculture are not perfect, and the overall situation of today's natural water environment is not very optimistic. While water quality control and breeding norms cannot be ignored, it is very important to cultivate varieties with good stress resistance. However, in the breeding process, in addition to the quality of the parents and the requirements of the breeding technology, the daily detection of the health status of the shellfish is an important factor for cultivating good varieties. Routine testing includes measuring respiration rate, digestibility, weight gain and other indicators. Although it can more accurately express the physiological state of shell...
