Description

A kind of rainbow trout artificial culture technology
Technical field
The present invention relates to a kind of rainbow trout artificial culture technology, particularly relate to and can improve rainbow trout and propagate incubation rate and survival rate artificially, scale cultivates rapidly a large amount of rainbow trout, increases economic efficiency.
Background technology
Rainbow trout is also known as waterfall fish, seven look fishes, it is one of large freshwater aquiculture kind of output high and colory four that FAO (Food and Agriculture Organization of the United Nation) promotes to the world, be listed in famous and precious fish in the world always, there is the advantages such as meat flavour deliciousness, nutritious, the few meat of thorn is many, edibility is high, growth is fished for rapidly, easily, efficiency of feed utilization is high, artificial propagation is simple and easy to do.But rainbow trout is in growth, reproductive process, to water temperature, water quality, the conditions such as light there are certain requirements, and therefore, sum up, refine and improve artificial propagation of rainbow trout technology, to the output improving rainbow trout, instruct the development of rainbow trout aquaculture, are significant.
Summary of the invention
The object of the present invention is to provide a kind of more effective artificial propagation of rainbow trout technology, improve the output of rainbow trout, increase economic efficiency.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of rainbow trout artificial culture technology, comprises the following steps:
Build rainbow trout cultivating pool;
Cultivate the parent population healthy and strong, fertility is strong;
Artificial insemination, hatching fry;
Cultivate fry;
Raise adult fish;
Control water quality.
On the basis of technique scheme, the present invention can also do following improvement:
It is as follows that further described culturing pool sets up concrete grammar:
Build prelarva pond, fry pond, fingerling pond, marketable fish poud, parent fish pond and reserve parent fish pond respectively, its area accounts for 0.5%, 1.0%, 12.5%, 80%, 3.0%, 3.0% of plant's gross area respectively; Prelarva pond, fry pond, fingerling pond are barnacle or xoncrete structure, and marketable fish poud and parent fish pond are soil property, barnacle or xoncrete structure; Prelarva pond, fry pond area 10-30m 2, depth of water 20-40cm; Fingerling pond area 50-100m 2, the depth of water 40-60cm; Marketable fish poud area 100-200m 2, depth of water 60-80cm; Parent fish pond area 100-300m 2, the depth of water 100-140cm; The height in fishpond exceeds water surface 20-30cm; Water inlet, discharge outlet and sewage draining exit are established in each fishpond; Water inlet, discharge outlet place arrange fish screen.
It is as follows that further described parent population cultivates concrete grammar:
Select physique stalwartness anosis, the parent population in age 4-5 age carries out anniversary cultivation from spring; Cultivation density is 5-10kg/m 2; First 6 months water temperatures of laying eggs are no more than 12 DEG C, strengthen water injection rate before sexual maturity; Sunshine time controls within 12h; Raise together with by female-male proportion 4:1, lay eggs first 1 month point and support; With crude protein be not less than 38%, crude fat not higher than 6%, carbohydrate do not feed higher than the complete feed of 12%; Ensure that in every kilogram of feed, vitamin A is not less than 2 million international units, vitamin D is not less than 2000 international units.
Further described artificial insemination, hatching fry concrete grammar are as follows:
Encasing raun afterbody with towel, making its gonopore towards adopting ovum basin, light pressure gonopore front belly, makes mature egg flow out along gonopore; With same method, milter seminal fluid is directly squeezed on ovum, every 5-7 tail female fish-egg 2-3 tail milter seminal fluid; Add a small amount of isotonic solution or clear water Quick uniform stirring 1min; Change water to stir 1-2 time; Leave standstill 30min, put in people's incubator and hatch; Overall process must be carried out in shading.
It is as follows that further described fry cultivates concrete grammar:
Fry opens the food stage and to throw something and feed egg yolk, water flea, silk earthworm, livestock liver and the fresh flesh of fish etc., and through 20d, body reaches 2.5cm, and body weight reaches 0.2g, forwards fry pond to and raises; Throw something and feed containing the complete feed of crude protein 40%-50%, crude fat 4%-15%, raw fiber 1%-3%, coarse ash 10%-16%, moisture 8%-12%, raise 1 year, enter the adult fish rearing stage.
Further described adult fish rearing concrete grammar is as follows:
Adult fish presses 200-250 tail/m 2density is put in a suitable place to breed; Raise with the complete feed of protein content 40%, fat content 7%-9%, digestible carbohydrate content 9%-12%; Particulate material diameter is 4-8mm; Every day throws something and feeds 3-4 time, adheres to that few throwing duty is thrown.
Further described Water-quality control concrete grammar is as follows:
Control water temperature at 13-18 DEG C, pH value is at 6.5-6.9, and dissolved oxygen amount is not less than 5mg/L, and ammonia nitrogen is no more than 1mg/L.
The invention has the beneficial effects as follows:
Fingerling grows neatly, and incubation rate is high, and survival rate is high, and output is high, can significantly improve the economic benefit of rainbow trout cultivation.
Embodiment
Build area 10m respectively 2, the prelarva pond of depth of water 20cm and fry pond, area 50m 2, the fingerling pond of depth of water 40cm, area 100m 2, the marketable fish poud of depth of water 60cm, and area 200m 2, the parent fish pond of depth of water 100cm.Select physique stalwartness anosis, the parent population in age 4-5 age is by density 5-10kg/m 2cultivate, feed with complete feed, and note regulating water temperature, water quality, the conditions such as sunshine.When Gunther parent fish spawning, encasing raun afterbody with towel, making its gonopore towards adopting ovum basin, light pressure gonopore front belly, makes mature egg flow out along gonopore; With same method, milter seminal fluid is directly squeezed on ovum, every 5-7 tail female fish-egg 2-3 tail milter seminal fluid; Add a small amount of isotonic solution or clear water Quick uniform stirring 1min; Change water to stir 1-2 time; Leave standstill 30min, put in people's incubator and hatch; Overall process must be carried out in shading.First throw something and feed after fry hatching egg yolk, water flea, silk earthworm, livestock liver and the fresh flesh of fish etc., through 20d, body reaches 2.5cm, and body weight reaches 0.2g, forwards fry pond to raise and complete feed of throwing something and feeding, and raises 1 year, enters the adult fish rearing stage.Adult fish presses 200-250 tail/m 2density is put in a suitable place to breed, raises with complete feed, and control water temperature at 13-18 DEG C, pH value is at 6.5-6.9, and dissolved oxygen amount is not less than 5mg/L, and ammonia nitrogen is no more than 1mg/L.
