A method of regulating the golden body color of large yellow croaker by using a class of functional peptides

Abstract

The invention discloses a method of applying a class of functional peptide to regulate golden yellow body color of large yellow croaker, and relates to large yellow croaker. The method is injecting the functional peptide, soaking the functional peptide, or taking the peptide orally; the method of injecting the functional peptide comprises the steps that alpha-melanocyte stimulating hormone is dissolved in normal saline with the sodium chloride concentration of 0.65-0.90 g / mL, intraperitoneal injection is conducted, the body color of the large yellow croaker turns to golden yellow from silver white, and the golden yellow color keeps 24 hours or longer; the method of soaking the functional peptide comprises the steps that a whole large yellow croaker fish is soaked in seawater containing thefunctional peptide with the concentration larger than or equal to 0.5 mM, after soaking, the body color of the large yellow croaker fish turns to golden yellow from silver white, and the golden yellow color keeps 24 hours or longer; the method of taking the functional peptide orally comprises the steps that the functional peptide solution is poured into the stomach of the large yellow croaker, the dosage is larger than or equal to 0.3 nmol per gram of weight, after gastric perfusion, the body color of the large yellow croaker turns to golden yellow from silver white, and the golden yellow color keeps 12 hours or longer.

Description

technical field [0001] The invention relates to large yellow croaker, in particular to a method for regulating the golden body color of large yellow croaker by using a class of functional peptides. Background technique [0002] Large yellow croaker (Larimichthys crocea), belonging to the order Perciformes, the family Scrotoaceae, and the genus Yellow croaker, also known as large yellow croaker, yellow croaker, and golden fish, is a warm-temperature migratory fish with rich nutrition. one of the classes. The body color of large yellow croaker is an important feature. The golden yellow croaker is deeply loved by consumers, so the market price of large yellow croaker is closely related to the golden color of the large yellow croaker. [0003] After long-term natural selection, each fish has evolved a specific body color to adapt to the ecological environment; fish body color plays an important role in camouflage, hiding, vigilance, and finding a mate [1] . The body color of ...
