Detecting method of fast discrimination of heat resistance of abalones

Abstract

The invention provides a detecting method of fast discrimination of heat resistance of abalones. Abalone samples to be detected are temporarily bred in a circular water system, and feeding, cleaning and breeding are conducted; shell attachments are removed, and drying is conducted; an infrared sensor is utilized to find the accurate position of the hearts of the abalone sample, so that the signal intensity is not lower than 1 V, and after the position is determined, the sensor is fixed to the shells of the abalones; the abalones are put back into seawater to be restored, water bath is utilized, temperature rising processing is conducted till the heart rates of the abalones are lowered, temperature rising is stopped, the abalones are transferred into normal seawater, the changes of the heart rates of the abalones and the corresponding temperatures are recorded in real time; the obtained heart rates and temperature data are processed, afterwards, with the temperatures being the horizontal axis and the heart rates being the longitudinal axis, an Arrhenius curve is drawn, linear regression is conducted on two curves in front and back of inflection points of the curves, a regression equation is obtained, a simultaneous equation is obtained, and the horizontal coordinates of the intersections are heart rate ABT values of the abalones; healthy individuals are randomly selected to be used for detection, and the average value is taken to be used for representing the heat resistance of each group.

Description

technical field [0001] The invention relates to the measurement of the temperature resistance of aquatic organisms, in particular to a method for quickly distinguishing the temperature resistance of abalone. Background technique [0002] Since ancient times, abalone has always been a precious food material in China, ranking first among the eight seafood treasures. my country began large-scale abalone farming in the late 1980s. By the end of 2013, its annual output exceeded 100,000 tons, and its direct economic output value exceeded 10 billion. Wrinkled plate abalone (Haliotis discus hannai) was originally the main cultured species in the northern sea area of ​​my country. In recent years, with the successful cultivation of the new variety "Dalian No. 1" and the breakthrough of breeding technology, its breeding range has continued to expand southward. It is the largest wrinkle plate abalone breeding area in China, and its annual output can reach 80% of the national output. A...

Problems solved by technology

[0003] The traditional research on temperature-resistant characteristics of abalone is mostly based on summer breeding data or laboratory evaluation methods represented by methods such as semi-lethal temperature. Therefore, accurate data cannot be provided, and the laboratory evaluation method represented by semi-lethal temperature and other methods usually changes the water temperature in a short period of time, and completes the evaluation work based on the survival rate of Bao. The damage of the abalone is extremely large, and after the evaluation is over, individuals with strong tolerance often cannot survive, resulting in the death of the experimental abalone
