Abstract

The invention provides a carp fry rearing method, comprising the following steps: preparing a 1- to 2-mu east-west fishpond, 0.8-1.2 meters in water depth with little mud, and clearing and sterilizing conventionally; applying fertilizer: applying fermented manure 7-10 days before fry are put in the pond, or applying inorganic fertilizer 5-10 kg/mu, and sterilizing with quick lime 150 kg/mu; putting fry: before putting fry, spreading an empty dense-eye net to remove wild impurities, or putting 50-80 fry of spotted silver carp for water trial, and putting fry 10-250000 fry/mu if safety is confirmed; the carp fry rearing method related herein enables higher fry survival rate, higher fry growth speed and convenience of management.

Description

A kind of Cyprinus carpio fry rearing method

Technical field

The present invention relates to a kind of Cyprinus carpio fry rearing method, belong to technical field of agricultural breeding.

Background technology

Cyprinus carpio, omnivorefish, happiness is gregarious and goes, and selects food and occupies.Fine and tender taste, meat nutritive value is the highest, and every hectogram meat contains 13 grams of protein, 11 grams of fat, and containing mineral such as substantial amounts of calcium, phosphorus, ferrum.Cyprinus carpio medical value is high, and its property is put down Sweet in the mouth, enters stomach, kidney, have with middle qi-restoratives, except the feed of thin, stomach warming, effect of invigorating middle warmer anger.Cyprinus carpio is widely distributed, in all parts of the country The most all there is production in waters, with 2～April and 8～the Cyprinus carpio of December the most fertile, for the important edible fishes of China One of.Largest body is about 30cm, and perching the degree of depth is 0～20 meter, nontoxic, and economical edible fishes are inexpensive.Existing Have in technology, be usually present the defect that Cyprinus carpio fry cultivation survival rate is low, management is inconvenient.

Summary of the invention

The present invention provides a kind of Cyprinus carpio fry rearing method, and the method makes the survival rate of fry high, fry length fast, and Convenient management.

For solving above technical problem, the present invention provides following technical scheme: a kind of Cyprinus carpio fry rearing method, including with Lower step: pond prepares: select 1-2 mu, depth of water 0.8-1.2 rice, few mud, East and West direction fishpond, level according to a conventional method, disappear Poison；Fertilising: under fry before the pool 7-10 days, can apply fermented-muck, and such as pigs and cattle feces 150-300kg/ mu, (5 choose a left side Right), it is possible to execute the inorganic fertilizer (chemical fertilizer, phosphate fertilizer etc.) of 5-10kg/ mu, carry out lime disinfection (consumption 150kg/ mu) simultaneously, After one week, under fry, pond is exactly wheel animalcule peak period, and the agreeable to the taste bait of fry is sufficient, robust growth.3 put Seedling: put before fry first with close It is wild miscellaneous that eye net draws abortive haul to remove, and also can put cheap flower silver carp seed 50-80 tail and carry out trying water, it was demonstrated that can put after all safety Fish, 10-25 ten thousand tails/mu.The pool under 4 clear water: not basal dressing, directly puts into fry, and this method is less because of bait wheel animalcule agreeable to the taste in water, The most enough, therefore fry is weak, and survival rate is the lowest.5 management: (1) feed supplement in good time: after fry enters pond, are a few days ago growing especially Hurry up, often occur that natural bait is not enough, therefore it is noted that feed supplement.Conventional Semen Glycines adds the making beating of ripe egg yolk and splashes and throw something and feed.Every day Every mu adds 3-5 ripe egg yolk with 2-4kg Semen Glycines and wears into slurry and splash immediately and throw something and feed, and emphasis feeds the water surface of several meters near pool side.Also may be used The fresh Sanguis sus domestica sprinkled after once filtering for every three days.Bean milk both can directly be eaten up by seed, it is also possible to water quality of fostering and apply fertilizer, abundant sky So bait.At present, market also there is fry stream lead to, likeness in form microcapsule or powder, can divide open the beginning to throw something and feed from 6-8, both can mend food, again Can lure that fry robs food into, thus facilitating digestion road is grown, be conducive to improving survival rate and strong sprout；(2) topdress and Guan Shui: every three It spraying fertilizer, allows wheel animalcule in water remain at a higher level.Also part can be taken out from more fertile marketable fish poud every day Water is added to fry pond can increase natural bait for fry, can prevent from again adding motor-pumped well water excess and causing the generation of gas bubble disease.Often Week should change water 1/3-1/2.(3) examine: should strengthen during fry rearing making an inspection tour.See that it is movable, eat food, grow, water quality Change, with or without the situation such as harmful animal, disease.Reply fry divides pond in good time simultaneously, prevents from overstocked causing specification uneven.If desired Also need to draw in the net to temper fry stamina intensifying.

This Cyprinus carpio fry rearing method that the present invention relates to, the method makes the survival rate of fry high, fry length fast, and And conveniently management.

Detailed description of the invention

A kind of Cyprinus carpio fry rearing method, comprises the following steps: pond prepares: selection 1-2 mu, depth of water 0.8-1.2 rice, Few mud, East and West direction fishpond, level according to a conventional method, sterilize；Fertilising: under fry before the pool 7-10 days, executes fermented-muck Enter, or execute the inorganic fertilizer of 5-10kg/ mu, lime disinfection, consumption 150kg/ mu；Put Seedling: put before fry first with close eye net Draw abortive haul to remove wild miscellaneous, or silver carp seed 50-80 tail of letting off fireworks carries out trying water, it was demonstrated that after all safety, fish, 10-25 ten thousand can be put Tail/mu；The pool under clear water: not basal dressing, directly puts into fry；Feed supplement: Semen Glycines adds the making beating of ripe egg yolk and splashes and throw something and feed；Or it is every The fresh Sanguis sus domestica sprinkled after once filtering for three days, or feed throwing fry material；Topdress and Guan Shui: every three days one time spraying fertilizer or every It is taken out part water from more fertile marketable fish poud and is added to fry pond；Observe: see that it is movable, eat food, grow, change of water quality/have unmatched Evil, disease；Fry is divided in good time pond；Draw in the net to temper fry stamina intensifying.

In the step of feed supplement, add 3-5 ripe egg yolk with 2-4kg Semen Glycines every day every mu and wear into slurry and splash immediately and throw something and feed, weight Point feeds the pool side water surface.

Detailed description of the invention of the present invention is not intended that the restriction to the application scope, every at present inventive concept Within spirit and principle, any amendment, equivalent and improvement etc. that one of skill in the art can make should be included in Within protection scope of the present invention.
