Embodiment 1

[0025] 1. Parent selection

[0026] (1) female parent

[0027] For mirror carp with scattered scales, it is required to select individuals with spindle-shaped body shape, no injury on the body surface, 3 to 5 years old, and 3.5 to 6.0 kg in individual weight as broodstock.

[0028] (2) male parent

[0029] For red crucian carp, it is required to select individuals with moderate body shape, pure red body color, no miscellaneous flowers, no injuries, strong physique, 2 to 3 years of age, and 150 to 300 g in individual weight as brood fish.

[0030] (3) Parent fish sex ratio

[0031] The ratio of female parent to male parent is 1:6~8. Parents also need to select and retain once before breeding, mainly to select and retain sexually mature individuals to ensure high reproductive rate, spawning rate and hatching rate.

[0032] 2. Breeding of broodstock

[0033] (1) Cultivation pool conditions

[0034] Broodstock ponds require a flat bottom, shallow silt, easy access and draina...

Embodiment 2

[0060] A method for artificial propagation of golden crucian carp is characterized in that comprising the following steps:

[0061] 1) parent selection: the age is 3 years old, the loose scale mirror carp that body weight is 3.5kg is used as female parent, and the age is 2 years old, and the red crucian carp that body weight is 0.15kg is used as male parent;

[0062] 2) broodstock cultivation: use the pond with depth of 1m as the cultivation pond, disinfect the cultivation pond before water injection, inject water 8 hours after disinfection, put in the female parent described in step 1) at a density of 90 tails per mu, and use 500 per mu The density of the tail is put into the male parent described in step 1), while ensuring the ratio of 1:6 between the female parent's throwing amount and the male parent's throwing amount, the feed amount fed every day is 1% of the total weight of fish in the cultivation pond, Feed protein content is 25% (w / w);

[0063] 3) Artificial reproduc...

Embodiment 3

[0066] A method for artificial propagation of golden crucian carp is characterized in that comprising the following steps:

[0067] 1) parent selection: the age is 5 years old, the scattered scale mirror carp that body weight is 6kg is used as the female parent, and the age is 3 years old, and the red crucian carp with a body weight of 0.3 kg is used as the male parent;

[0068] 2) broodstock cultivation: use the pond with a depth of 1.5m as the cultivation pond, disinfect the cultivation pond before water injection, inject water for 10 hours after disinfection, put in the female parent described in step 1) at a density of 110 tails per mu, and put in the female parent described in step 1 at a density of 110 tails per mu. The density of 800 tails is put into the male parent described in step 1), while ensuring that the ratio between the female parent's feeding amount and the male parent's feeding amount is 1:8, and the amount of feed fed every day is 3% of the total weight of f...

Abstract

The invention provides an artificial carassius auratus propagation method. The method is creatively improved in the aspects from the source of parent selection and parent fish rearing to the following aphrodisiac drug preference, incubation method design and the like, a complete technological method for artificially propagating carassius auratus is formed, and the propagation rate, the spawning rate and the incubation rate are remarkably increased. By the adoption of the preferred technical scheme, vitamin is added to fodder before parturition to promote gonad development of parent fish; the preferred temperature of water where the parent fish injected with aphrodisiac drug are located ranges from 21 DEG C to 22 DEG C, so that parent fish rutting and egg laying efficiency is further improved; the preferred incubation temperature ranges from 20 DEG C to 23 DEG C so that fertile eggs can be incubated. By the adoption of the technical scheme, a series of creative design is conducted on the technological conditions, the remarkable technical effect is achieved, the condition control angle and the condition control depth are remarkably improved or optimized compared with those in the prior art, and meanwhile the method is easy to implement, low in cost and remarkable in large-scale application prospect.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for artificial propagation of golden crucian carp. Background technique [0002] As a hybrid species, golden crucian carp has the advantages of small head, high back, thick body, golden yellow body, fast growth, high yield, strong disease resistance, etc. It is also easy to raise, with high meat content and high protein and amino acid content in muscle , At present, large-scale cultivation has been carried out in ponds, reservoirs, cages, etc. in Tianjin, Hebei, Shandong, Inner Mongolia and other provinces and cities in my country, all showing excellent breeding effects and obvious economic benefits. [0003] Just because golden crucian carp is a hybrid species, its strain quality and breeding effect directly affect the quality of the final fish. In the breeding work of golden crucian carp in the prior art, there are generally differences in parent selection, breedi...
