Abstract

The invention relates to a totally artificial breeding method for Coilia ectenes, belonging to the technical field of fish culture. The method is characterized by comprising the following process steps of parent fish source; parent fish select breeding comprising standing / flowing water combined reinforced breeding; artificial induced spawning measure comprising parent fish selection, semen collection, dug roe inspection, induced spawning water temperature confirmation, parent fish matching, hormone injection, artificial insemination and the like; microflow water incubating; and summer flower and fish fry breeding. The invention promotes the parent fish sex gland to grow to maturity and ovulate by measures of reinforcing parent fish nutrition reinforced breeding, feeding hormone, flowing water stimulating and regulating and the like and normalizes the artificial induced spawning and insemination process, originally creates a simple flowing water incubating device of a pelagic egg and reinforces the management and ecological regulation of incubation period, thereby effectively solving the technical problems of artificially breeding Coilia ectenes. The induced spawning rate of artificial breeding is 33 percent, the fertilization rate is 48 percent and the hatching rate is 44 percent.

Description

technical field

[0001] The invention relates to a breeding method for anadromous fish, in particular to a fully artificial breeding method for anchovy, belonging to the technical field of fish breeding. Background technique

[0002] Coilia nasus belongs to the genus Coilia nasus, also known as long-jawed coilia, commonly known as "saury", "hair fish", and "shaving fish". Known for its tender meat and delicious taste, it is a rare migratory fish that enjoys the reputation of one of the "three delicacies of the Yangtze River".

[0003] In recent years, due to the influence of many factors such as overfishing and the deterioration of the ecological environment, the resources of the anchovy have declined sharply, while the market demand has continued unabated, and even reached the dilemma of having a price but no market. The market price of the standard anchovy is as high as 6,000 yuan / Kg. Therefore, it is of great significance to break through the artificial breeding of the c...
