Method for judging low-temperature injury degree of chlamys nobilis

Abstract

The invention discloses a method for timely judging the low-temperature injury degree of chlamys nobilis. According to the invention, a timely chlamys nobilis low-temperature injury judgment standard is established, the digestive gland and adductor muscle of the chlamys nobilis are respectively subjected to fat and glycogen content detection, and the injury degree judgment standard is compared, specifically, low-temperature first-degree injury refers that the fat content of digestive glands is less than or equal to 40% and the glycogen content of adductor muscles is less than or equal to 15mg / g; low-temperature second-degree injury refers that the fat content of digestive glands is less than or equal to 45% and the glycogen content of adductor muscles is less than or equal to 20mg / g, and is higher than the first-degree injury standard; and low-temperature non-injury refers that the fat content of digestive glands is greater than 45% or the glycogen content of adductor muscles is greater than 20mg / g. According to the method, whether the chlamys nobilis is in the low-temperature injury state or not and the degree of the low-temperature injury state can be judged by detecting the fat content and the glycogen content, the degree of the low-temperature injury to parent scallops required by breeding can be judged in time, and support is provided for breeding of low-temperature-resistant varieties.

Description

technical field [0001] The invention relates to a method for judging the degree of low-temperature damage of shellfish, which belongs to the field of shellfish breeding, and in particular to a method for judging the degree of low-temperature damage of scallops. Background technique [0002] Chlamys nobilis Reeve belongs to the phylum Molluscs, Phallobranches, Pearl Oysters, and Scallopidae. It is a warm-water marine shellfish and is widely distributed in the southeast coast of my country, Thailand, Vietnam, Indonesia and Japan. Because of its advantages of fast growth, short breeding cycle, and high economic benefits, it is widely favored by farmers. It has been cultivated on a large scale in Fujian, Guangdong, Guangxi, and Hainan in the 1980s, and has become the most important marine cultured shellfish in southern my country. One of the categories, it has brought huge economic benefits to my country's mariculture industry. As the scallop scallop is a warm-water shellfish, l...
