Problems solved by technology

[0002] It is native to the Murray River in Australia. It is a national treasure fish in Australia. The scientific name "Murraycotian" belongs to the Perciformes family. Insects and saprolegniasis, the survival rate of fry is extremely low, and sometimes the whole army will be wiped out. So far, there are very few successful cases of large-scale breeding of introduced fry

Embodiment 1

[0027] Embodiment 1: a kind of artificial propagation method of new variety Longwenban is characterized in that comprising the following steps:

[0028] 1) Build a temperature-controlled broodstock breeding pond

[0029] A circular cement pool with a diameter of 5.0m is built on the indoor ground. The pool wall is 1.6m high. Time-controllable incandescent lamps 100w2 are installed above each broodstock breeding pond, and the indoor temperature can be regulated at 15-26°C.

[0030] 2) Broodstock fish nest setting

[0031] Place 4 broodstock fish nests in every pond, and the broodstock fish nests are made of dark gray PVC pipes with a diameter of 500mm and a length of 1100mm PVC pipes lined with mosquito nets.

[0032] 3) Breeding of broodstock

[0033] In November every year, select 5-year-old and above, 7-8kg, healthy broodstock, put 2 pairs in each pond, control the temperature above 15°C, dissolve oxygen 9mg / L, PH7.5-8.5, light time 12h / day, light intensity...

Abstract

The invention relates to an artificial breeding method of a new species of Murray cods. Conditions for culturing the new species in the source area Australia are simulated. The method includes the following steps that a temperature-controlled parent Murray cod breeding pond is built, a parent Murray cod nest is arranged, parent Murray cod breeding is carried out, parturition is hastened, artificial impregnation is carried out, zygotes are artificially hatched, and Murray cod fries are cultured; in this way, artificial breeding of the Murray cods is successful, and the artificial breeding method is an innovation in China.

Description

technical field [0001] The invention relates to the technical field of fish reproduction, in particular to an artificial propagation method of a new species of dragon pattern. Background technique [0002] It is native to Murray River, Australia. It is a national treasure fish of Australia. Its scientific name is "Murraycotian". Insects and saprolegniasis, the survival rate of fry is extremely low, and sometimes the whole army will be wiped out. So far, there are very few successful cases of large-scale breeding of introduced fry. Dragon stripe is a large ferocious carnivorous fish with a long lifespan and a large body size of up to 30kg. It is late in sexual maturity and can only be used for breeding at the age of 5. There are currently breeding ponds for broodstock in China that can be used for breeding. Very few, only Jiangsu Zhongyang Group conducts systematic scientific research on dragon stripes, including research on biology, growth, development, gonad developmen...
