La3+ elements are added into fry rearing water 15 days after the time from roe distribution to fry hatching, and the concentration of La3+ reaches 0.5-1.0 mg/L. An improvement is carried out on the basis of a conventional nibea albiflora fry rearing method, the lanthanum elements of a certain concentration are added into the fry rearing water, fries which quickly grow are obtained, and meanwhile the fry rearing survival rate is increased.
Description
Technical field
The invention belongs to technical field of aquaculture, be specifically related to a kind of spotted maigre seed fast breeding method.
Background technology
Spotted maigre (Nibeaalbiflora), is under the jurisdiction of Osteichthyes (Osteichthyes), Perciformes (Perciformes), Sciaenidae (Sciaenidae), Nibea (Nibea).Domesticly mainly be distributed in the Huanghai Sea, the Bohai Sea, the East Sea and the South Sea, in water warm, lower floor fish, in its mating season of trip to coastal waters, belong to migration fishes in season.Suitable temperature range 18-28 DEG C, proper salinity level 14-32 ‰.This meat quality of fish is fertile, and mouthfeel is unique, is of high nutritive value, be over the years China a kind of there is higher economic worth fish for kind, there is wide cultivation DEVELOPMENT PROSPECT.Along with people increase for the demand of spotted maigre, wild resource cannot meet the market supply, and artificial breeding is imperative, but comparatively single about the seed rearing mode of spotted maigre at present, seed rearing speed is comparatively slow, expects a kind of birth of spotted maigre seed fast breeding method.
Summary of the invention
The technical problem to be solved in the present invention is to provide the seed fast breeding method of a kind of spotted maigre, the present invention improves on the basis of the spotted maigre offspring seed cultivation method of routine, certain density lanthanum element is with the addition of in seedling water, obtain the seed of growth fast, improve survival rate of seedling simultaneously.
The present invention is achieved by the following technical solution:
A seed fast breeding method for spotted maigre, is characterized in that 15d adds La in seedling water after cloth ovum to prelarva membrane
3+element, described La
3+concentration in seedling water reaches 0.5-1.0mg/L.
A seed fast breeding method for spotted maigre, concrete steps are as follows:
(1) collection of fertilized egg
In the mating season of spotted maigre, the parent population picking out more than 3 good ages of gonad development selects fingerling as staying, and obtains fertilized egg;
(2) incubating oosperm condition
Cloth ovum density is 8 × 10
3-1 × 10
4grain/m
2, cultivate water temperature 21-23 DEG C, salinity 25-26, pH7.8-8.2, dissolved oxygen>=6mg/L, light keeps soft, avoids sun direct projection, and inflation, hydrostatic are cultivated, and aeration quantity size is in suspended state to keep fertilized egg;
(3) interpolation of element
The micro-LaCl added in seedling water
36H
2o is pure for analyzing; First being configured to concentration of metal ions with distilled water is that the mother liquor of 100mg/L is for subsequent use, from cloth ovum, adds the mother liquor configured in hatching pail, makes La in hatching pail
3+concentration reaches 0.5-1.0mg/L; La
3+no longer add after 15d, 15d after element interpolation lasts till prelarva membrane;
(4) the throwing something and feeding of bait
Between nursery stage, every day adds concentrated chlorella solution in nursery bucket, and according to water colour regular replenishment chlorella solution; 3d opening after prelarva membrane, open-mouthed bait selects S type brachionus plicatilis, within 1st, throws something and feeds twice; Start domestication after membrane 15d to throw something and feed artemia nauplii, the domestication that starts after membrane 20d to intersect is thrown something and fed manufactured feed, manufactured feed particle diameter now used is 0.2mm, every day, domestication was thrown something and fed 5-7 time, along with growth and the schistostoma increase of fish, be excessively the manufactured feed of 0.5-0.7mm to particle diameter of throwing something and feeding, feeding volume is 4 ﹪-6 ﹪ of fish body weight;
(5) water is changed
From cloth ovum, front 8d does not change water, starts to change water after 8d, along with the growth of prelarva, quantity of exchanged water and aeration quantity increase gradually, and nursery later stage quantity of exchanged water reaches ﹪ every day 100, start 15d to prelarva membrane in nursery bucket, quantitatively supplement the La configured according to the quantity of exchanged water of every day from cloth ovum
3+element mother liquor, mother liquor matching while using;
(6) daily management
Carry out daily tour between seedling culturing vehicle, ensure that oxygen is sufficient, water quality is pure and fresh, removes dead seedling in time, keeps nursery inner bucket water clean environment, starts to inhale the end once every 1-2d from bait throwing in, and action is wanted slowly, to avoid sucking-off prelarva.
The present invention's beneficial effect compared with prior art:
Cultivating spotted maigre seed by prior art needs 60-70d to emerge, and seed size reaches 1.8-2.5cm, and seed size is uneven, and between individuality, difference is larger.And technical solution of the present invention can realize 40d emerges, fry specification reaches 2.0-2.5cm, shortens the cultivation time, reduces fry cost.And the seed vigor that technical solution of the present invention obtains is better, neat specification, improves the survival rate of spotted maigre seed rearing; This method is easy and simple to handle simultaneously, is easy to promote.
Embodiment
Below by embodiment, technical scheme of the present invention is further explained, but protection scope of the present invention is not by any pro forma restriction of embodiment.
A seed fast breeding method for spotted maigre, its concrete grammar is as follows:
(1) collection of fertilized egg
In the mating season of spotted maigre, pick out the parent population that gonad development is good, parent population is the kind fish of selecting and remain after 3-4 raises and train in plant, through artificial induced spawning, is fertilized, washes the steps such as ovum, filtration, floating and obtain fertilized egg for subsequent use.
(2) incubating oosperm condition
Incubating oosperm and larval and juvenile fish are cultivated and are all carried out in the cylindrical hatching pail of blueness of high 80cm, diameter 80cm.During cloth ovum, water level remains on 60cm, and cloth ovum density is 8 × 10
3-1 × 10
4grain/m
2, cultivate water temperature 21-23 DEG C, salinity 25, pH7.8-8.2, dissolved oxygen>=6mg/L, light keeps soft, avoids sun direct projection, and inflation, hydrostatic are cultivated, and aeration quantity size is in suspended state to keep fertilized egg.
(3) interpolation of element
