Problems solved by technology

Although our country currently has nearly 100 papers and patents on the research on the black-tailed red carp, and the water surface of the black-tailed red carp is 1 million mu, but no one has applied for a patent on the artificial reproduction technology of the black-tailed red carp. The standardization and protection of the artificial propagation technology of the red salamander is still in a blank state

Embodiment 1

[0025] 1) Breeding of broodstock:

[0026] A. In August 2013, we collected wild P. chinensis with nets in the waters of Luzhou City, Sichuan Province, and selected healthy, uninjured, and 200-600g wild P. chinensis as backup broodstock;

[0027] B. Put the selected broodstock of the black-tailed red carp into the reserve broodstock pond for backup cultivation, and the initial breeding density is 1.5kg / m 3 . The reserve brood pond has an area of ​​1000m 2 , the bottom gradient [equal to (height of the lowest point of the bottom of the fish pond (m)-height of the highest point of the bottom of the fish pond (m)) / length of the fish pond (m)*100] is 2%, the height is 1.5m, and the water depth is 1.1m. The drainage flow is 0.15m 3 / s. The pH of the backup cultivation water is 7.5, the dissolved oxygen is 10mg / L, and the water temperature is 24°C. The back-up cultivation feed is an extruded floating carp feed, and the quality percentage composition of protein in the back-up cul...

Embodiment 2

[0041] 1) Breeding of broodstock:

[0042] A. In May 2012, we collected wild P. chinensis with nets in the waters of Luzhou City, Sichuan Province, and selected healthy, uninjured, and 200-600g wild P. chinensis as backup broodstock;

[0043] B. Put the selected broodstock of the black-tailed red carp into the reserve broodstock pond for backup cultivation, and the initial breeding density is 1kg / m 3 . The reserve brood pond has an area of ​​300m 2 , the bottom gradient is 1%, the height is 1.2m, the water depth is 0.9m, and the inflow and drainage flow is 0.1m 3 / s. The pH of the backup cultivation water is 6.5, the dissolved oxygen is 7.0mg / L, and the water temperature is 6°C. The back-up cultivation feed is extruded floating carp feed, and the mass percentage content of protein in the backup cultivation feed is 30%, and the daily feeding amount of the cultivation feed is 1% of all broodstock body weights, and it is fed twice a day, respectively at 9 am. 1:00 p.m., 5:00...

Embodiment 3

[0057] 1) Breeding of broodstock:

[0058] A. In August 2013, we collected wild P. chinensis with nets in the waters of Luzhou City, Sichuan Province, and selected healthy, uninjured, and 200-600g wild P. chinensis as backup broodstock;

[0059] B. Put the selected broodstock of the black-tailed red carp into the reserve broodstock pond for backup cultivation, and the initial breeding density is 2kg / m 3 . The reserve brood pond has an area of ​​2000m 2 , the bottom gradient is 2%, the height is 1.5m, the water depth is 1.1m, and the inflow flow is 0.2m 3 / s. The pH of the backup cultivation water is 7, the dissolved oxygen is 5.0mg / L, and the water temperature is 15°C. The back-up cultivation feed is extruded floating carp feed, and the mass percent content of protein in the back-up cultivation feed is 35%, and the daily feeding amount of the cultivation feed is 1% of all broodstock body weights, and it is fed twice a day, respectively at 9 am. 1:00 p.m., 5:00 p.m.;

Abstract

The invention discloses an ancherythroculter nigrocauda artificial breeding method comprising the steps of (1) parent fish breeding, (2) artificial spawning induction, (3) artificial insemination, (4) artificial incubation and (5) fry culturing. The method is simple, and has high operability and good practicality. With the method, ancherythroculter nigrocauda fry scale expansion and industrialized production can be realized, ancherythroculter nigrocauda aquaculture development can be promoted, and ancherythroculter nigrocauda wildlife resource can be effectively protected. As a result of tests, with the method, an ancherythroculter nigrocauda induced spawning rate is 80-90%, an ancherythroculter nigrocauda fertilization rate is 60-90%, and an ancherythroculter nigrocauda hatching rate is 70-90%.

Description

technical field [0001] The invention relates to the technical field of artificial reproduction of fish, in particular to an artificial propagation method of the red-tailed red carp. Background technique [0002] Ancherythroculternigrocauda Yihet Wu (Ancherythroculternigrocauda Yihet Wu), whose local name is Gaojian, belongs to the genus Ancherythroculternigrocauda Yihet Wu, and is distributed in the main and tributaries of the upper reaches of the Yangtze River. It is a unique fish in the upper reaches of the Yangtze River. It lives in the middle and upper waters, lays sticky eggs, and is a freshwater carnivorous fish. [0003] At present, there are many scholars who study the black-tailed catfish. These scholars have either published papers or applied for related patents, such as Le Peiqi (2000. Chinese Zoology Telephytes Cypriniformes (Volume 2). Beijing : Science Press), Fish Research Office of Hubei Institute of Hydrobiology (1976. Yangtze River Fish. Beijing: Science P...
