Description
Technical field
The present invention relates to imperial fine goldfish cultivation field, more particularly to a kind of mating system of telescope goldfish.
Background technology
Current telescope goldfish is bred without system, the standard of specification, it is easy to cause the feelings that fertility rate and hatchability is low
Condition；And warm canopy or cement pit raise limited amount, it is cumbersome, large-scale production is restricted.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of mating system of telescope goldfish is provided.
The present invention to achieve the above object, using following technical scheme：
A kind of mating system of telescope goldfish, is concretely comprised the following steps：
(1) preparation in pond
Select and manage including parent fish pond, spawning pond and the breeding environment of hatchery；
The area of parent fish pond is 2-2.5 mus, and the pond depth of water is 1.3-1.5m；Spawning pond is soil property pond, and area is 2.5-3
Mu, the depth of water is 1m, and water injection is convenient, sunny, environment quiet；The area of hatchery is 3-4 mus, depth of water 1.2-1.3m；
Sterilization is thoroughly being leveled in spawning pond and hatchery using preceding progress, eliminates enemy and trash fish, was added water and dried in the air using first 5 days
Shine；
(2) screening and cultivation of parent population
Parent population selects the raun and the milter in 1 age in 2-4 ages, and the wherein ratio of male and female parent population is 1：2；The parent population chosen is put
Support in parent fish pond, the density put in a suitable place to breed be ten thousand tails of 0.6-0.7/mu, parent population put in a suitable place to breed after 2-3 days after start to feed feed, feed
The middle mass fraction for adding mineral matter vitamin and crude protein more than 40%, Feeding time control the morning twice, afternoon two
Secondary, feeding volume is adjusted in time according to season and water temperature, and summer and autumn day feeding rate is 2-3% in 2-4%, spring day feeding rate；
(3) prepare before Gunther parent fish spawning and spawning
It is put into after fish nest is sterilized in spawning pond, parent population to be laid eggs is put into spawning pond, the ratio of male and female parent population
Example is 1：1.5；From at dusk 18:00- mornings 2:00 per fish nest density of observation, 2 every other hour:00-6:00 sees per half an hour
Examine once, when it is every fish nest is glued ovum density in 0.9-1 ten thousand when, more renew fish nest；
(4) hatching of embryonated egg
Fish nest with embryonated egg is taken out and is put into hatchery, is kept into water 20-30cm, every mu puts 30, fish nest, is hatched
Water temperature is at 18-22 DEG C, and dissolved oxygen is in more than 5.0mg/L, and fry takes out fish nest after being born one week；
(5) cultivation of fry
Fry feeds yolk water after being born 3 days, every ten thousand tail feeds 1 soft-boiled eggs Huang, yolk is fully smashed to pieces to rub and washed, 5-10 days
The cladocera after filtering is fed afterwards and coordinates yolk and soya-bean milk, feeding mixed feed after 20 days；
(6) screening of fry
Primary election is carried out when fry total length length is to 2-3cm, tail exception, the inferior fish of physical abnormality is screened out；When fry is complete
It is long to 4-5cm when, carry out final election, screen out that tail is asymmetric, the tail heart is askew, build shade deviation fish, before final election draw in the net for 1 time
Take exercise；Fish is carried out when fish grows up to marketable fish preferably, to select the defect individual that graceful posture, lovely luster, character are protruded,
It is preferred that preceding drawn in the net to take exercise twice.
In the screening process of parent population, selection tail type is symmetrical, anal fin balance, and bright in colour, feature is protruded, and eyes are intact, rich
Full mellow and full healthy disease-free without wound, total length is that 12-15cm fishes are used as parent population.
In the cultivating process of parent population, before parent population is put into parent fish pond with 5% saline sook 5min；Parent population be put into after
Splashed in parent fish pond within two days and prevent the Chinese herbal medicine of saprolegniasis, wherein Chinese herbal medicine is answering that radix scutellariae, Chinese ephedra, kuh-seng and Chinese gall are made
Square Chinese herbal and crude drugs preparations, a Chinese herbal medicine of being splashed again after five days；Parent population was splashed once after being put into every 8-9 days pre- bacteriological protection and posts
Infested nitrifier；Monthly add water 2-3 times, the amplitude added water every time is controlled in 25cm.
The beneficial effects of the invention are as follows：The invention provides a kind of mating system of the telescope goldfish of specification, realize simple
The operating process of science, possess higher fertility rate and hatchability, while can classify filters out the commodity of high-quality high-quality
Fish, so that production efficiency is improved, it is final to realize higher economic benefit.
