Abstract
The invention belongs to the field of cultivation and particularly relates to a loach larva cultivating method. The method includes the following steps that firstly, breeding and oviposition are performed; secondly, eggs are put into an incubation pool to be incubated evenly, an oxygen boosting rod is placed beside the pool, the oxygen boosting rod is placed at the bottom of the pool after loach larvae get out of membranes, and the loach larvae are cultivated; thirdly, pond cleaning medicine is used for cleaning the pond, water filling and fertilizing are started three days later, and when the color of water of the pond is cultivated to be yellow green, the loach larvae are put into the pond; fourthly, before the loach larvae are put into the pond, the loach larvae are put into oxygen bags at first, the oxygen bags are put into the pool for buffering and then, the loach larvae are put into a net box; fifthly, milk powder and quail egg yolk are used as bait for feeding the loach larvae; sixthly, powder materials starts to be cast after seven to ten days. The rate of survival of the larvae cultivated with the loach larva cultivating method is improved to be more than 35%. By adjusting the position of the oxygen boosting rod, the density of the eggs can be adjusted, workloads are reduced, the cost in cultivating the larvae is reduced and economic benefits are boosted.
Description
Technical field
The invention belongs to cultivation field, be specifically related to a kind of loach seedling-cultivating method.
Background technology
Loach is described as " in water ginseng ", its delicious flavour, fine and tender taste, nutritious.According to analysis, containing 18.4 grams, protein, 2.9 grams, fat in every hectogram loach meat, vitamin B1, A, C content are all higher than other fish.In addition, loach property is flat, taste is sweet, enter liver spleen kidney, and pharmaceutically also have higher value, therefore, loach export trade amount increases year by year in recent years, and the consumption figure of domestic loach is also in rising trend.
Because natural loach resource far can not meet the consumption demand of people, therefore loach breeding industry also starts to enter the fast-developing phase.Existing loach hatching, cultivating method is: be positioned in the cement pit of sterilizing in advance by loach parent population and lay eggs, and the fertilized egg of giving birth to continuation hatches into mud fish fry in cement pit, after the flat trip of fry, fry is transferred to the pond after prior rich water
The pool is cultivated, about 1 month, cultivates into the specification of more than 3 centimetres, about 5 months, and loach grows to about 5 grams, is loach large size fingerling.
But existing method, when laying eggs, due to the accumulation of ovum, causes the seedling rate of hatching low, loach nursery low in juvenile fish opening stage survival rate.
Summary of the invention
For solving the problem that in present loach seedling raising process, survival rate is low, the invention provides a kind of loach seedling-cultivating method, improve the survival rate in seedling raising process.
The present invention is achieved through the following technical solutions: a kind of loach seedling-cultivating method, comprises the following steps:
(1) breeding is laid eggs and is selected healthy male and female loach ratio to be 2:1, starts to hasten parturition during sexual maturity, puts obstetric table into, make it carry out mate and oviposit after injection human chorionic gonadtropin;
(2) ovum is put into hatchery evenly to hatch, oxygenating rod is placed on pool side, and after membrane, oxygenating rod is placed at the bottom of pond, cultivates loach seedling;
(3) clean up the pond with medicine of cleaning up the pond, start water filling after 3 days, the depth of water 60-80cm, then carry out rich water with amino acid, when pond water color cultivates yellow green, loach seedling starts the lower pool, throws in seedling 15-20 ten thousand tail for every mu;
(4) be first placed in oxygen bag before the pool under loach seedling, put in pool water within and cushion 10-20min, be then placed in net cage;
(5) feed as bait with milk powder and Quail Egg, every 100,000 tail loach seedling use 3-6 Quail Egg or milk powder 500-800g;
(6) start powder of throwing something and feeding after 7-10 days, powder is milk powder, every day 4-6 times, 1-2kg/ mu of at every turn throwing something and feeding.
For preventing ovum pile-up, evenly hatch in hatchery, oxygenating rod is placed on pool side, is placed at the bottom of pond after membrane, adds the amount of oxygen around ovum, and ovum can be made to disperse, and reduces the density of ovum, significantly improves the membrane rate of mud fish fry.
Described medicine of cleaning up the pond is at least one in quicklime and bleaching powder.
For preventing high temperature, with cistern to water filling in pool, each 10-20cm, reaches the object of cooling oxygenation.
Beneficial effect of the present invention: carry out loach nursery by this method, seedling percent, more than 35%, improves the survival rate of seedling, the density of ovum is regulated by the position adjustments of oxygenating rod, reduce the amount of labour, and reduce seedling cost, add economic benefit.
Embodiment
A kind of loach seedling-cultivating method, comprises the following steps:

(2) ovum is put into hatchery evenly to hatch, oxygenating rod is placed on pool side, and after membrane, oxygenating rod is placed at the bottom of pond, adds ovum ambient oxygen tolerance, and ovum can be made to disperse, and reduces the density of ovum, can significantly improve the membrane rate of mud fish fry, cultivate loach seedling;
(3) clean up the pond with medicine of cleaning up the pond, start water filling after 3 days, the depth of water 60-80cm, then carry out rich water with amino acid, when pond water color cultivates yellow green, loach seedling starts the lower pool, throws in seedling 15-20 ten thousand tail for every mu;
(4) be first placed in oxygen bag before the pool under loach seedling, put in pool water within and cushion 10-20min, be then placed in net cage;
(5) feed as bait with milk powder and Quail Egg, every 100,000 tail loach seedling use 3-6 Quail Egg or milk powder 500-800g;
(6) start powder of throwing something and feeding after 7-10 days, powder is milk powder, every day 4-6 times, 1-2kg/ mu of at every turn throwing something and feeding.
For preventing high temperature, with cistern to water filling in pool, each 10-20cm, reaches the object of cooling oxygenation.
