Abstract
The invention discloses a kind of methods that batch production perch large size seedling seed is cultivated, including：1. spray seed is put in a suitable place to breed；2. early period cultivates；3. the later period cultivates：When perch seedling body is up to 2cm, start instruction food, first stop eating for 24 hours, then it is higher than 45% 0# perch mixed feed with protein content, artemia nauplii is gradually substituted in 20%, 50%, 80%, 100% ratio, fast slow principle again completes instruction food in 2-3 days after replacement velocity is preferably first slow, and 4. concentrate cultivations.Perch offspring seed cultivation method of the invention, instruction food can be concentrated to complete bait conversion, reduction cuts one another's throats, the fry of cultivation is uniform in size, perch weed survival rate can reach 60% or more, weed survival rate is greatly enhanced, the above-mentioned deficiency of existing perch rearing of fingerling is compensated for, there is very big practical application value.
Description
Technical field
The invention belongs to freshwater aquiculture fields, cultivate the big specification of Micropterus salmonoides in industrial aquaculture more particularly to one kind
The method of seed.
Background technique
Micropterus salmonoides are because growing the features such as fast, disease is few, with good meat quality, high financial profit, by as the excellent of freshwater aquiculture
Non-defective unit kind.Supply falls short of demand for big specification Micropterus salmonoides seed in recent years, and 4cm or more seed demand especially long to body is more urgent.Add
Perch belongs to predacious fish in state, uneven due to ingesting in seed rearing, fingerling size heterogeneity is big, exists and kills and devour mutually
Problem greatly reduces weed survival rate.Lack a kind of can effectively reduce at present to kill and devour mutually, makes its feeding habits well from animal
Property bait be converted to mixed feed, and keep the large size seedling seed breeding method of high-survival rate.
Chinese patent（CN1653891）A kind of breeding method of Latescal carifer is disclosed, the desalination of larvae cultivation pond, room are passed through
Outer pond domestication, cultivates Latescal carifer seed, but refers to the method and cultivate Micropterus salmonoides, there are seed individual differences obviously,
Outdoor ponds are difficult to concentrate instruction food, cut one another's throats the problems such as still serious, only 20%- lower so as to cause weed survival rate
30%。
Summary of the invention
For the above limitation, the object of the present invention is to provide a kind of methods that batch production perch large size seedling seed is cultivated, with more
Mend the above-mentioned deficiency of existing rearing of fingerling.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of method that perch large size seedling seed is cultivated, includes the following steps：
（1）It is carried out in batch production cement pit indoors, putting perch spray density in a suitable place to breed is every cube of water body of 100,000 tail；
（2）In the early period of seed rearing, using wheel animalcule and artemia nauplii as open-mouthed bait, primary every 4h feeding, feeding is arrived
Most probably the above seed is satiated with food, and clears up dirt before feeding every time, miniflow water is to guarantee that water quality is pure and fresh；
（3）When perch it is long to 2cm or more when, concentrate instruction food to make its conversion of food habit, first stop eating for 24 hours, then with protein content height
In 45% perch mixed feed, artemia nauplii is gradually substituted in 20%, 50%, 80%, 100% ratio, replacement velocity is preferably first
Fast slow principle again after slow；
（4）After the completion of instruction food, being cultivated in the cement pit relaying sequel of the same size for going to 10-20 cubes, support to 4cm or more
It can sell.
Preferably, the step（1）Middle water temperature is 20-25 DEG C.
Preferably, the step（3）Middle perch mixed feed is the perch mixed feed that partial size is less than 1.5mm.
Preferably, the step（3）The instruction food of completion in middle 2-3 days.
Preferably, the step（4）Middle cement pit breeding density is that the every side's water body of 10,000 tails is advisable.
Compared with the existing technology, the present invention has the beneficial effect that：
Perch offspring seed cultivation method of the invention can concentrate instruction food to complete bait conversion, and reduction cuts one another's throats, and the fry of cultivation is big
Small uniform, perch weed survival rate can reach 60% or more, greatly enhance weed survival rate, compensate for existing perch
The above-mentioned deficiency of rearing of fingerling has very big practical application value.
Specific embodiment
The present invention is further described below with reference to embodiment.
The method that a kind of perch large size seedling seed of the invention is cultivated, includes the following steps：
1. spray seed is put in a suitable place to breed
It is 1 m in area3-5m3Batch production cement pit in, control water temperature be 20-25 DEG C, water quality is pure and fresh pollution-free, miniflow water
Keep Dissolved Oxygen in Water in 5mg/L or more, the perch seed every cube of water of 100,000 tail put physical health in a suitable place to breed, do not carry pathogen
Body.
2. early period cultivates
As perch open-mouthed bait, artemia nauplii vigor decline in fresh water is fast for culture of rotifera, artemia nauplii, feeds
Speed is unsuitable too fast, is advisable with not sinking to the bottom, is fed once every 4h, guarantees that eighty per cant or more fry is satiated with food, and clears up dirt before feeding,
Pull dead seedling out in time, miniflow water guarantees that water quality is pure and fresh.
3. the later period cultivates
When perch seedling body is up to 2cm, starts instruction food, first stop eating for 24 hours, 45% 0# perch is then higher than with protein content
Mixed feed gradually substitutes artemia nauplii in 20%, 50%, 80%, 100% ratio, and replacement velocity is preferably first slow rear fast slow again
Principle instruction food is completed in 2-3 days.Difference instruction food mode result is as follows：
| Serial number | Mixed feed substitutes artemia mode | As a result |
| 1 | 100% replacement is without transition | It does not ingest mixed feed, 10% or less survival rate |
| 2 | It is gradually substituted in 50%, 100% ratio, instructs 2-3 days food phase | Instruction food result is general, survival rate 20%-30% |
| 3 | It is gradually substituted in 20%, 50%, 80%, 100% ratio, instructs 2-3 days food phase | Instruction food result is good, and survival rate reaches 60% |
| 4 | It gradually substitutes, instructs the food phase 7 days in 20%, 50%, 80%, 100% ratio | Survival rate 60%, does not significantly improve, but increased costs |
It is cultivated 4. concentrating
After instruction food is completed, fry of the same size is gone to suitable mesh sieve in 10-20 cubic metres of cement pit and continued
Concentrate cultivate, breeding density be 10,000 tail per cubic meter of waters be advisable, continue the mixed feed for feeding suitable particle diameter, support to 4cm with
On.
