Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to a culture management method capable of promoting gonad development of parent cyprinus carpio.
Background
The fancy carp is a large-scale rare ornamental fish which is prepared by artificially breeding and directionally cultivating a carp mutant strain. Koi is reputable to the world by the habits of body, gorgeous color, gorgeous stripe, unrestrained and unrestrained swimming posture and temperate and is called as 'living jewel in water' and 'artwork capable of swimming'. As a high-quality fresh water ornamental fish breeding variety with wide prospect, the fancy carp has the problems of unsynchronized population maturity of parent fish bred in a pond, delayed production and death of the parent fish, difficult opening of the fries and the like, so that the artificial breeding efficiency is low, the production cost is high, and the large-scale breeding requirement cannot be met.

The invention aims to provide a culture management method capable of promoting gonad development of parent fish of fancy carps for protecting parent fish resources of high-quality fancy carps, improving spawning rate and hatching rate of artificial propagation and ensuring fry quality, and realizes efficient and large-scale culture.
In order to achieve the purpose, the invention adopts the following technical scheme:
a breeding management method capable of promoting gonad development of parent koi fishes comprises the following specific steps:
s1, selecting parent fish
Selecting parent fish with strong physique, complete limbs, no deformity, dense color, brightness, luster, clear stripes, left-right balance, harmonious body shape, high height and long length at a ratio of 1:2.6-3, beautiful appearance, and obvious and clear variety characteristics; adopting male and female separate pools;
s2 strengthening body constitution before overwintering
Adjusting the feed component ratio, increasing fat content in the feed, reducing protein content, adding multivitamins for aquatic products, hepatoprotective agent, and immune polysaccharide, and performing intensive feeding before overwintering;
s3 management during overwintering period
Strengthening physique, strict quarantine and disinfection: before the fingerlings or parent fishes enter the overwintering pond, strengthening physique domestication, strengthening later-stage feeding, fattening and preparing overwintering; quarantine and disinfection are strictly carried out before the fish is put into the pool, and the fish diseases are discovered in the quarantine and are treated by symptomatic medicines;
overwintering with rich water: introducing rich water containing phytoplankton into the overwintering pool before overwintering, or applying inorganic fertilizer in the overwintering pool to culture phytoplankton, wherein the rich water is used as an oxygen source for water in the ice pool;
keeping open ice: if the area of the black ice is large and thick, the black ice is broken and fished out, so that the overwintering pool is made to be the open ice again;
fertilizing and water injection: when the snowplow has a good light transmission overwintering water body, a large amount of zooplankton is not contained in water, the water color is dark, and the dissolved oxygen is still greatly reduced, fertilizing is carried out;
and (3) oxygenation in the overwintering pond: during the overwintering period, taking oxygenation measures to ensure that the fish safely overwinter;
s4, management after overwintering
Increasing the feeding amount: after the spring festival, protein intake is increased, and the need of gonad development is ensured;
attention is paid to disease prevention and control: along with the rise of water temperature, the water bodies of the whole pond are disinfected once after the pond is unfrozen and opened, so that the fish bodies are detected in time, the fish diseases are found to be treated in time, and a foundation is laid for the healthy production of the fishes in spring;
water quality regulation: old water is pumped out after spring and new water is added into the pond, the water environment of the pond is improved, the physicochemical factors of the water quality are detected in time, and the activity of the fish is closely observed.
And step S1, selecting the koi parent fish according to the principle of breeding high-quality and new species by mating the same variety and different strains or different species.
In step S2, the added vitamins for aquatic products include vitamin C and vitamin E.
In step S3, the determination criterion for darker water color is that the transparency is less than 50 cm.
In step S3, the oxygenation measures include mechanical oxygenation, water injection oxygenation, chemical oxygenation and biological oxygenation.
In step S4, the feeding amount is increased to 3% -4% of the fish weight in the end of 2 months.
In step S4, the common winter fish diseases include saprolegnia and trichomonas sp.
The invention has the beneficial effects that: the invention provides a breeding management method capable of promoting the gonad development of parent fishes of fancy carps, which can scientifically and effectively improve the gonad development of the parent fishes, reduce the breeding cost and improve the survival rate of the parent fishes and fingerlings.
