Problems solved by technology

[0004] In the whole process of breeding koi, it is very important to successfully hatch koi fry from the fertilized eggs of broodstock, which needs to be paid more attention to, otherwise it will be time-consuming and labor-intensive; screening of koi fry is also a long-term and hard work; Mistakes in the hatching of koi fry and the breeding of koi fish will seriously affect the economic benefits of the koi business, and even cause the koi breeders to go bankrupt and cry without tears

Embodiment 1

[0041] A kind of method for artificially hatching koi provided by the present embodiment, a kind of method for artificially hatching koi, comprises the following steps:

[0042] Step 1. 2 to 3 days before spawning, prepare the spawning pool and disinfect the spawning pool; aerate and dechlorinate the spawning pool for more than one day (before putting broodstock in);

[0043] Step 2. Select female and male koi broodstock with strong physique, obvious strain characteristics, bright color, pure color without miscellaneous spots, stable genetic traits and mature gonads. The female broodstock weighs 2.5-2.9 kg, and the male broodstock weighs 2-2.8 kg. kg, the ratio of selected male and female broodstock is 1:3;

[0044] 30 to 50 days before spawning, the male fish and the female fish are separated and raised in separate ponds, and the feed is artificially fed according to the total number of broodstock fish, and the amount of feed fed every day is 2% of the total fish tail quality...

Embodiment 2

[0060] Same as Example 1, the difference is that in this example, the formula of the "normal nutritional feed" fed to fry is by mass ratio: 1 part of shrimp meat, 1 part of soybean powder, 2 parts of flour, and half of coarse wheat flakes 1 / 1000 part of seaweed, 1 part of egg, 2 / 1000 part of betaine, 1 / 1000 part of fishy peptide, appropriate amount of baking powder.

[0061] The production of the "normal nutritional feed" referred to above is as follows: fully mix the ingredients, add water and stir until the paste is fermented for 20 to 30 minutes, place it on the dish in batches, then heat it in a microwave oven for 10 minutes, take it out and cool it down to room temperature naturally, and then put it Freeze in the refrigerator for 4 hours, then crush and dry in the sun, and store in a cool and dry place for later use.

Embodiment 3

[0062] Embodiment three: same as embodiment one, the difference is:

[0063] In the present embodiment, the formula of the normal nutritional feed fed to fry is by mass ratio: 1 part of shrimp meat, 1 part of soybean powder, 2 parts of flour, half part of coarse oatmeal, half part of seaweed, 1 part of egg, 1 part of betaine 2 / 10 parts, 1 / 10000 parts of fishy peptide, 1 / 10000 parts of baking powder;

[0064] The method of throwing something and feeding described normal nutritional feed is:

[0065] The water temperature is 1-2 times a day at 15-20 degrees, and feed when the temperature is the highest in the day; cover the sunshade net to prevent the water body from direct sunlight and cause the water temperature to rise, the water temperature is 20-30 degrees 2-4 times a day; the water temperature is 30 degrees The above fry should not exceed 4 times a day, and adult fish should not exceed 2 times a day.

Abstract

The invention discloses an artificial fancy carp hatching method, and belongs to the technical field of aquaculture. The artificial fancy carp hatching method comprises the following steps: performingdisinfection, aeration and dechlorination on a spawning pond before spawning; selecting parent fishes with strong physique and obvious strain characteristics to lay eggs and perform insemination; performing incubating on the fertilized eggs for 4-7 days to obtain fish fry; temporarily prohibiting feeding 24-36 hours after the fertilized eggs begin to form the fish fry; observing yolk sacs, and starting to feed filtered egg yolk and soybean milk when the yolk sacs are about to disappear and the fish fry begin to float upwards and swim horizontally; when swim bladders of the fish fry are inflated and yolk sacs completely disappear, adopting normal nutrient feed to feed the fish fry; after 7-10 days, putting the hatched fry into a soil pond for cultivation management, then classifying and screening the fry of the fancy carp, and reserving individuals with obvious characteristics and bright colors. The fancy carp fry cultured by using the fancy carp hatching method provided by the invention are high in survival rate, keep the characteristics of the original parent fish, and have great ornamental value.

Description

technical field [0001] The invention relates to a method for artificially hatching koi carps, which is mainly suitable for the breeding of koi carps in the central and eastern regions of my country, and belongs to the technical field of aquaculture.
