[0030] Preparation of antifreeze

[0031] (A) Preparation of the premix: first add 0.2-0.3kg of evening primrose oil dropwise to 1kg of egg white while stirring, stir and mix well, then heat in a water bath at 55-65°C for 5-8 minutes, 10000-12000r / min stirring for 15-20 minutes, centrifuging to take the supernatant; then adding 0.05-0.08kg papaya seed stem cell extract and 0.02-0.04kg yeast dextran to the supernatant, and ultrasonically oscillating evenly to obtain the premixed solution. spare;

[0032] (B) Preparation of antifreeze: first mix 3-4 kg of formaldehyde solution with mass concentration of 8-12% with 0.08-0.12 kg of sodium chloride and 1 kg of maltose, then add 0.2-0.3 kg of premixed solution, and ultrasonically oscillate evenly to obtain The antifreeze.

Embodiment 1

[0054] A kind of artificial propagation method of spotted carp, concrete steps are as follows:

[0055] 1) Preservation of sperm: In April 2019, at the Aquaculture Technology Extension Station of the Agricultural and Rural Bureau of Xingbin District, Laibin City, Guangxi, on April 15, 2 male fish of about 1.5kg were purchased from the market. Bring the testes of the male fish they slaughtered back to the aseptic laboratory of the extension station. After the male fish is slaughtered, take out the testes, wipe off the surface moisture of the testes with a dry towel, and cut the testes into pieces with scissors. The milky white semen can be seen with the naked eye, and then separate Grind it with a homogenizer several times, suck a few drops of semen with a straw and put it on a glass slide, activate it with water and observe the motility of the sperm under a microscope, and divide the semen with a motility greater than 90% into the prepared beakers , add the antifreeze solution...

Abstract

The invention provides a method for artificial reproduction of the spotted carp. First, the semen is frozen and stored, and then the female fish is induced to give birth during the breeding season, and the eggs are squeezed out, and then the eggs are mixed with the thawed semen to obtain fertilized eggs. Finally, The fertilized eggs are hatched and the seedlings are cultivated, which realizes the artificial reproduction of the spotted carp fish, solves the technical problem that the current artificial breeding of the spotted carp fish fry is difficult, and makes mass production of the spotted carp seedlings a reality.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to an artificial propagation method of spotted carp. Background technique [0002] Spotted carp is a species of the genus of the genus Pleuridae, also known as carp, sesame carp, and white-bearded carp. Spotted carp inhabits the bottom of rivers and feeds on small aquatic animals, such as aquatic insects, small fish, shrimps, etc., and also eats a small amount of higher aquatic plant debris. Spotted carp is distributed in the Qiantang River, Jiulong River, Han River, Pearl River, Yuan River and other water systems in China, the Mekong River Basin in South Asia, and inland rivers in Malaysia and Indonesia. Spotted fish is a large-scale carnivorous economic fish with a relatively mild temperament. It has no scales in its body, and its meat is tender, delicious, and high in nutritional value. An important economic fish in the production area. Due to immature arti...
