Problems solved by technology

[0003] At the end of 2003, the Heilongjiang Fisheries Research Institute introduced this fish from Uzbekistan to my country for the first time. At present, the breeding has been successful, but it has not been able to provide a large supply of seedlings, resulting in the high level of mackerel seedlings.
At present, technical problems such as large-scale artificial propagation and seed cultivation of giant barb cannot be overcome.

Embodiment 1

[0128] The artificial propagation test of embodiment 1 giant barb

[0129] 1 oxytocin appliance. A medical syringe with a capacity of 1-2mL and several needles (assorted), and an oxytocic agent for broodstock injection, dissection trays, scissors, knives, tweezers, etc., several towels for extracting testes, and several hard feathers , 1 small mouth bottle of 1000mL, 2 straws of 20mL or 50mL, several basins or buckets.

[0130] 2 Types and doses of oxytocin. ①HCG300~500IU / tail+DOM0.5~1mg / tail; ②LRH-A22~3μg / tail+DOM0.5~1mg / tail. The dosage for male fish was halved.

[0131] 3 operation of oxytocin injection. The oxytocic agent is made into injection with normal saline. The injection method is back muscle injection or intraperitoneal injection. Before injection, ether is used for anesthesia. The injection volume of about 20g mudfish is 0.5-0.7mL, and the depth of the needle should be controlled at 0.2-0.3mL. cm. In order to control the depth of the needle, a thin rubber tu...

Embodiment 2

[0139]Example 2 Influence of Density of broodstock for induced spawning on the induced spawning effect of giant barb

[0140] 1 Materials and methods

[0141] 1.1 Test site

[0142] The experiment was carried out in the Huchengang Reservoir. The water quality in the reservoir area is clear, with an annual average transparency of 25.12cm. The heavy metals do not exceed the standard. The surface layer of the aquaculture water area has basically no salinity, and the bottom layer of the reservoir reaches a salinity of about 3‰. The dissolved oxygen in the water body is 7.0±0.5mg / L, and the pH value is 7.0-8.0. The water flow has a little flow velocity when the reservoir gate is draining, and a slight flow velocity when the wind is strong.

[0143] The experiment used reservoir cages to stimulate the production of giant catfish. The broodstock temporary cage is used to temporarily raise the broodstock injected with the first injection of oxytocic agent. Its size is 3m × 3m × 2m,...

Abstract

The invention discloses a culture method of barbus capito. The method comprises the following steps that barbus capito in rivers, lakes, reservoirs and other natural water is selected, or artificially cultured adult barbus capito is selected as parent fishes; a culture pond, the parent fish stocking number, the stocking mode and the culture and feeding mode are selected, and management is enhanced; the parent fishes are subjected to artificial spawning induction; artificial fertilization is carried out; artificial incubation is carried out; fry rearing is carried out; fingerling culture is carried out. Culture and screening of the parent fishes, the odinagogue variety, the concentration ratio, the injection mode, incubation conditions and other conditions are optimized, and the spawning induction rate, fertilization rate and incubation rate of the cultured barbus capito all reach 90% or above.

Description

technical field [0001] The application belongs to the field of aquaculture, and in particular relates to a method for cultivating giant barb fish. Background technique [0002] Barbus capito (Barbus capito) belongs to Cyprinidae, Bosubinae, and Barb genus. It is native to the Amu Darya River in Uzbekistan. It is a rare large-scale economic fish in the country. Delicious meat, strong adaptability to salt and alkali, adult body weight 3-6kg, maximum individual body length 70cm, weight 12kg, is one of the local rare and large-scale economic varieties. [0003] At the end of 2003, the Heilongjiang Fisheries Research Institute introduced this fish from Uzbekistan to my country for the first time. At present, the breeding has been successful initially, but it has been unable to provide a large supply of seedlings, resulting in a high level of seedlings of giant barb. The Fuling District of Chongqing City introduced trial breeding in 2014, checked in the spring of 2016, reached se...
