Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a breeding method for the Australian dragon stripe, which solves the problem that the existing Australian dragon stripe has a low fertilization rate, the reproduction is very easy to damage the brood fish, causes the reproductive ability of the brood fish to decline, and the resulting fry has weak constitution and is easy to cause varieties. Degradation and other issues

Embodiment 1

[0041] 1) prepare broodstock cultivation pond: prepare the broodstock cultivation pond with an area of ​​300 square meters, clean the bottom of the pond and the wall of the pond, and evenly splash the bottom of the pond and the wall of the pond with a concentration of potassium permanganate aqueous solution of 1 gram / ton of water for disinfection for one day. Change the water to clear the pond the next day, and release 0.8 meters of water after clearing the pond;

[0042] 2) Select broodstock: In October every year, select 7-year-old female broodstock weighing 10-15 kg with complete fins, and 7-year-old male broodstock weighing 10-15 kg with complete fins, the number of male broodstock and female broodstock The ratio is 1:2;

[0043] 3) Prenatal breeding of broodstock: Put the selected broodstock into the broodstock cultivation pond, feed the compound feed with 45% protein content, and carry out nutritional strengthening for the broodstock for 1 month; then control the tempera...

Abstract

The invention provides a breeding method for maccullochella peelii, which adopts the combination of artificial breeding and natural breeding. The breeding method comprises the following steps: 1) preparing a parent fish rearing pond; 2) selecting parent fish; 3) performing antenatal rearing on the parent fish; 4) arranging a roe laying device; 5) performing roe laying and fertilization; and 6) hatching fertilized roes. According to the breeding method for the maccullochella peelii, provided by the invention, each step is simple and convenient to operate, and the fertilization rate (the percentage of the fertilized roes can reach 80-90%) of the roes of the maccullochella peelii and the hatching success rate of the fertilized roes are effectively increased; in addition, the parent fish is not injured in the breeding process, the fertilized roes are effectively prevented from being threatened by diseases such as water molds and the like in the hatching process, the breeding cost is reduced, and the breeding density is increased.

Description

technical field [0001] The invention relates to the technical field of fish reproduction, in particular to a breeding method for Australian dragon stripes. Background technique [0002] The Australian dragon stripe has a special appearance and delicious taste, and is known as the "National Treasure Fish" in Australia. Its meat is tender and delicious, thick, with few thorns, and rich in four kinds of amino acids and EPA and DHA nutrients. It is one of the high-quality fish. The breeding of Australian dragon stripes in my country is still in the initial stage. Only a few enterprises in Zhejiang and Fujian have experimented with breeding, and a small amount of sales have not been widely promoted. The domestic and foreign markets are huge. [0003] At present, artificial reproduction is generally adopted in Australian dragon stripes, that is, injection of gonadotropin to stimulate production of parent fish, artificially extruding eggs and sperm, placing them in a fertilization...
