Description
Technical field
The invention belongs to fish culture technical fields, and in particular to a kind of particle feed for rockfish fry cultural method.
Background technology
Grouper is to belong to water warm, eurysalinity, large and medium-sized predacious fish, is our southern areas close to seashore
With fish pond or the rare kind of cage culture.Grouper is that a kind of high protein, the high-grade marine product of low fat and people are celebrating
The first-class delicacies of feast.Since the area of domestic cultivation at present is few, cultured area is little, and cultural method tradition falls behind, lithosporic
The survival rate of fish fry cultivation is not high, and supply falls short of demand for the grouper cultivated at present, cannot meet the needs in market.
Invention content
It is an object of the invention to：Solve the problems, such as that fry survival rate is not high in current particle feed for rockfish fry breeding process, carries
A kind of particle feed for rockfish fry cultural method effectively improving particle feed for rockfish fry survival rate is supplied.
The technical solution adopted by the present invention is as follows：
A kind of particle feed for rockfish fry cultural method, it is characterised in that：Include the following steps：
Step 1, aquaculture pond prepare, and waterwheel is provided in aquaculture pond；
Breeding water is put into the cultivation of step 1 by step 2, preparation breeding water using sand filter seawater as breeding water
Chi Zhong, and the dissolved oxygen in breeding water；
Step 3, hatch fish roe, fish-egg is positioned in container and is hatched, and container is positioned in aquaculture pond, and the water in container is
Breeding water, water temperature are controlled at 30 degree；
Step 4, fry cultivate, and after step 3 hatch fish roe, the fry hatched are put into aquaculture pond and is cultivated, is being cultivated
It is provided with shelter in pond, water temperature is controlled in 28-35 degree, feeds feed daily 4 times, for the first time 5. -6 periods in the morning
It feeds；
Step 5, fry sieving seedling separation often spend 30 days to fry and carry out harvesting, sieving, by fry unified specification by size,
Different specification point ponds are cultivated, and feed minced fillet to fry.
Further, in the step 2 breeding water through disinfection by ultraviolet light.
Further, for fry overall length when 10mm is descended, for density in 400-800 tails/cubic meter, fry is complete in the step 4
When length is more than 10mm, density is in 200-400 tails/cubic meter.
Further, 2-4 should be selected to feed a little when fry cultivation feeds feed in the step 4.
Further, feed includes biological feedstuff and mixed feed in the step 4.
Further, in the step 2 dissolved oxygen in 7-10mg/L.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1, in the present invention, it is provided with waterwheel in aquaculture pond, ensures that the abundant convection current of levels water body, water body keep good shape
State is conducive to the survival and growth of particle feed for rockfish fry；
2, in the present invention, breeding water ensure that the good of water quality by disinfection and dissolved oxygen, be provided to particle feed for rockfish fry
Sufficient oxygen is avoided because the food ration that low dissolved oxygen seriously reduces grouper leads to the problem of fry death, is improved
The survival rate of fry；
3,2-4 are selected to feed a little in the present invention, when feeding feed to fry, it can be ensured that all fries can be enough
It is full；
4, in the present invention, 5. -6 periods, particle feed for rockfish fry will carry out first time feeding before day in the morning
It looks for food, at this time if inanition, fry have autotomy phenomenon in water, feeding is carried out to fry before day, it can be apparent
Reduce the autotomy phenomenon of fry；
5, in the present invention, cultural method adjusts water temperature, reasonable arrangement breeding density strengthens battalion by providing good water quality
It supports, raising vigor, which realizes, improves particle feed for rockfish fry survival rate, reduces the purpose mutually killed and devour.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, the present invention is carried out below further
It is described in detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not intended to limit the present invention.
A kind of particle feed for rockfish fry cultural method, it is characterised in that：Include the following steps：
Step 1, aquaculture pond prepare, and waterwheel is provided in aquaculture pond, ensure that the abundant convection current of levels water body, water body keep good
Good state is conducive to the survival and growth of particle feed for rockfish fry.
Step 2 prepares breeding water, and using sand filter seawater as breeding water, breeding water is rested through disinfection by ultraviolet light
It grows and is put into the aquaculture pond of step 1 with water, and the dissolved oxygen in breeding water, dissolved oxygen gives particle feed for rockfish fry in 7-10mg/L
Sufficient oxygen is provided, avoids because the food ration that low dissolved oxygen seriously reduces grouper leads to the problem of fry death, carries
The high survival rate of fry.
Step 3, hatch fish roe, fish-egg is positioned in container and is hatched, and container is positioned in aquaculture pond, and the water in container is
Breeding water, water temperature are controlled at 30 degree.
Step 4, fry cultivate, and after step 3 hatch fish roe, the fry hatched are put into aquaculture pond and is cultivated, is being cultivated
It is provided with shelter in pond, such as suspension seaweed, Chinese ephedra leaf or bottom are launched plastic tube etc. and can all be reduced and kill and devour mutually, water
Temperature control system feeds feed 4 times daily in 28-35 degree, and 5. -6 periods feed in the morning for the first time, and particle feed for rockfish fry is in day
It will look for food before bright, at this time if inanition, fry have autotomy phenomenon in water, fry is carried out before day
Feeding can be substantially reduced the autotomy phenomenon of fry.
Step 5, fry sieving seedling separation, under normal circumstances, particle feed for rockfish fry will kill and devour existing more than overall length 2cm
As to substantially reduce seed rearing survival rate, often spending 30 days to fry and carrying out harvesting, fry is unified rule by sieving by size
Lattice, different specification point ponds is cultivated, and feeds minced fillet to fry, it is possible to reduce autotomy, to improve the survival rate of fry.
Further, for fry overall length when 10mm is descended, for density in 400-800 tails/cubic meter, fry is complete in the step 4
When length is more than 10mm, density keeps rational and feeds density in 200-400 tails/cubic meter.
Further, 2-4 should be selected to feed a little when fry cultivation feeds feed in the step 4, it can be ensured that Suo Youyu
Seedling can have enough.
Further, feed includes biological feedstuff and mixed feed in the step 4, enriched nutritive, and raising vigor realizes
Improve the purpose of particle feed for rockfish fry survival rate.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
