Abstract
The invention discloses an improved propagation method for spotted silver carps. The improved propagation method comprises the following steps of putting fish grass into a fish pond, and setting the water depth as 40-50cm and water temperature as 15-18 DEG C, wherein the water in the fish pond is flowing circulating water; selecting local spotted silver carps with unit weight of 2-4kg as father parents, selecting local spotted silver carps with unit weight of 10-15kg as mother parents, and putting the father parents and mother parents of the spotted silver carps into the fish pond for mixed culture 20 days before propagation, wherein the ratio of feather parents and mother parents of spotted silver carps is 3-4:1; if the spotted silver carps spawn via vaginas during propagation, manually extruding for spawning, wherein the spawns spawned at the beginning are white; when the spawns spawned by extrusion are light green, immediately stopping extruding for spawning. The method has the advantages that the spawning amount of the spotted silver carps is increased by 20-30% than the natural spawning amount; when the fingerlings hatched by the spawns grow up, the space in the abdominal cavity is reduced, the meat quality is fine, the taste is delicious, the meat is similar to the meat of black carps, the figure is similar to the figure of the spotted silver carps, the disease-resistant capability is high, and the spotted silver carps are easy to culture.
Description
Technical field
The present invention relates to a kind of improvement propagation method of variegated carp.
Background technology
Along with the development of society, growth in the living standard, people more and more focus on the food absorbed; Fish due to not fatty, and have higher nutritive value, are more and more liked.Wherein variegated carp is often edible one, variegated carp is also named bighead, fish head is large, account for 1/3rd of body length, turn black and have piebald in side, eye position is lower, fish oil containing a kind of needed by human body in fish brain, and in fish oil, be rich in polyunsaturated fatty acid, be a kind of nutrient of needed by human, maintenance can be played, improve, improve the effect of cerebral function.The glue that the following meat of the fish gill is transparent, moisture is sufficient, and collagen is rich in the inside, can resist human senescence and repair soma tissue.
But variegated carp is bred under field conditions (factors), variegated carp is not fully ovulated, and variegated carp resistance against diseases is reducing tendency, and the meat of variegated carp compares with carp, black carp, does not have the fine and tender taste of black carp or carp.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of improvement propagation method of variegated carp, guarantees the ovulation amount and the resistance against diseases that improve variegated carp, improves the meat of variegated carp simultaneously.
The technical solution used in the present invention is as follows:
The improvement propagation method of this kind of variegated carp, comprises following operating procedure:
(1) select fish pond, place water shield, the depth of water 40-50 centimetres, water temperature 15-18 DEG C in fish pond, the water in fish pond is the cycle water of flowing;
(2) male parent selects local variegated carp, and female parent selects local variegated carp, and male parent variegated carp weight is 2 kilograms-4 kilograms, and maternal local variegated carp weight is 10 kilograms-15 kilograms;
(3) in breeding first 20 days, male parent variegated carp and maternal variegated carp are put into above-mentioned fish pond and raises together with, the quantitative proportion of male parent variegated carp and maternal variegated carp was: 3-4:1;
(4) feeding thrown between breeding period is containing the abundant water of microorganism;
(5) find between breeding period that the private parts of variegated carp has ovum to discharge, adopt manual compression ovulation, the ovum starting to discharge is white, when the ovum finding that extruding is discharged is light green color, stops extruding ovulation immediately.
Adopt said method, variegated carp ovulation amount increases by 20-30% than spontaneous ovulation, and after the fry of this egg hatching grows up, abdominal space diminishes, fine and tender taste, delicious, meat deflection black carp, and build deflection variegated carp, premunition is strong, easily cultivates.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.
Embodiment
Below will be described in detail the preferred embodiments of the present invention.Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
The concrete steps of the present embodiment are as follows:
(1) fish pond of Jiu Zhou town, Huangping County mining under reservoir is selected in the enforcement place of this embodiment, places water shield, the depth of water 40-50 centimetres, water temperature 15-18 DEG C in fish pond, and the water in fish pond is the cycle water of flowing;
(2) male parent selects Huangping County variegated carp, and female parent selects Huangping County variegated carp, and male parent variegated carp weight is 2 kilograms-4 kilograms, and maternal local variegated carp weight is 10 kilograms-15 kilograms;
(3) in breeding first 20 days, 80 male parent variegated carps and 25 maternal variegated carps are put into above-mentioned fish pond and raises together with;
(4) feeding thrown between breeding period is containing the abundant water of microorganism;
(5) find between breeding period that the private parts of variegated carp has ovum to discharge, adopt manual compression ovulation, the ovum starting to discharge is white, when the ovum finding that extruding is discharged is light green color, stops extruding ovulation immediately.
Adopt said method, variegated carp ovulation amount increases by 20-30% than spontaneous ovulation, and after the fry of this egg hatching grows up, abdominal space diminishes, fine and tender taste, delicious, meat deflection black carp, and build deflection variegated carp, premunition is strong, easily cultivates.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present invention.
