Description
The present invention relates to a kind of artificial screening method of the high-quality colony of brown croaker and its screening in culture fishery for technical field
Device, belong to Fishery cultural technique field.
Technical background brown croaker (latin name Miichthys miiuy) is commonly called as " rice fish ", and it is sub- to be under the jurisdiction of Osteichthyes, spoke fin
Guiding principle, Perciformes, Sciaenidae, brown croaker category, seabed of the substrate for mud or silt is liked to inhabit in, is coastal waters temperature water borne base migrant
Class, it is coastal to be distributed widely in China north and south.The meat quality of fish is fresh and tender, nutritious, economic value is high, and its fish glue can be made into rare Hai Zhen
Product " fish maw ", it is a kind of more rare marine fishes.Brown croaker individual is big, knot group's property is strong, growth is fast, property is violent, happiness adverse current, feeding habits
Extensively, form that the cycle is short, high temperature resistant, grow suitable 17-33 DEG C of water temperature, 29-32 DEG C of optimum water temperature, suitable salinity 25-32, pH be suitable
Scope 7.8-8.3, dissolved oxygen should reach more than 4 mg/litres, be the excellent species of coastal waters cage culture.
Elite germplasm screening is excavated and using the important content for being always Aquaculture Science research, for a long time by natural money
Source is increasingly failed, and artificial screening seriously lags and cultivated parent and for many generations supported from numerous influence, the common aquaculture object in China
Grow survival rate and specific yield go fromes bad to worse, germplasm degradation phenomena has turned into serious obstruction China's aquaculture upgrading synergy
Great realistic problem.The screening and nurturing research for undoubtedly efficiently carrying out high-quality parent turn into current China's aquaculture scholars
The focus of concern.
Artificial orientation selects system to carry out the conventional method of aquaculture object germplasm screening, is selected based on multiple target character
High complexity and low success rate, to improve choice accuracy and accuracy rate, take mostly both at home and abroad at present using single traits as selection
The group directional selection mode of target, selected objective trait relate generally to body colour, the speed of growth, anti-adversity and to certain element or
The single specific character such as the enrichment of material and production capacity, there should be optimal cultivation to integrate with real aquatic products fine variety production and give birth to
The theory of production performance mutually deviates from.
The optimal comprehensive production performance of cultivation and its high-quality colony refer to：In involved consortive group of flora large sample, in constitution, predation
Sensitivity, the speed of growth and the upper comprehensive score highest colony of commodity economy value, its final selective ratio should be less than or equal to small
Probabilistic standard.Selecting the purpose for most preferably cultivating the high-quality colony for integrating production performance is：1st, there is excellent genetic background, through essence
The heart, which is cultivated, to breed parent as high-quality；2nd, in the fish of tool grouping behavior, the colony of the optimal comprehensive production performance of cultivation
Often it is top dog in the consortive group of flora shoal of fish, through raising and train meticulously, signal transmission in kind can be run through, guide and lead increasing
Grow that area is of the same race to be released the shoal of fish and enter artificial default feeding ground.
Failed increasingly actual, the most recent two decades that increasingly sharpen with ocean " desertification " to reverse traditional fishery resource conscientiously
Between departments of fishery administration at different levels of China persistently increase investment to propagation fishery this capital-intensive industry, but
Because the rate of recapture is low and cultivation effect visual evaluation technology does not obtain essence and solved for a long time, cause reality of the various circles of society to propagation fishery
Border effect is passed different judgements on, and the sound of query is continuous.The propagation rate of recapture and propagation actual effect are effectively improved, is responded with directly perceived to propagation
The query of fishery, it has also become the lasting significant technology issues for promoting propagation fishery sustainable health development to face and reality test.
Wherein regnant high-quality individual is screened in group's property shoal of fish is tied, carries out artificial domestication, is run through signal transmission in kind,
Guide and lead breeding blanket is of the same race to release the shoal of fish into artificial default feeding ground, undoubtedly for the raising propagation rate of recapture and intuitively
Particularly important effect will be played by responding propagation fishery actual effect.
Therefore it is easy, easily operated and can intuitively filter out and have from the alternative shoal of fish to establish a kind of method for research and development
The screening technique of the high-quality colony of the optimal comprehensive production performance of cultivation, and a set of screening plant to match therewith of design, just
Seem very urgent and important.
Numerous studies show that the animal with grouping behavior often forms the community characterized by " domination --- subordinate "
Grade, wherein the colony being top dog often has most strong constitution and optimal cultivation synthesis production performance." net is broken
Fish escapes " it is phenomenon most commonly seen in aquaculture production, when aquaculture net cage occurs damaged, the shoal of fish meeting in top stream mode
Successively from net cage breakage it is orderly flee from, wherein be first away from aquaculture net cage often be exactly wherein be top dog
High-quality colony.At the same time, in the shoal of fish cultivated in same net cage, weight gain performance it is most strong also tend to be wherein grab eat
The high-quality colony being top dog during thing.Therefore, screened with cultured fishes " the broken fish of net escapes " characteristic and weight gain performance
The method being combined, us can be easily helped to look for the finally selected high-quality target shoal of fish.
In view of described above, this method cultivates consortive group of flora as screening object using the brown croaker with knot group, top Flow Behavior habit,
Carry out high-quality mass screening, can effectively evade and be disturbed caused by age, breeding environment and breeding way difference.
Consortive group of flora refers to the group of individuals of the same age of the same race for undergoing identical breeding environment and identical breeding way.
Using consortive group of flora as screening object, according to the actual impossibility principle of small probability event, innovatively propose and establish
One kind utilizes " the broken fish of net escapes " characteristic and weight gain performance to screen the high-quality mass screening method of brown croaker being combined and its screening plant.
Statistically it is referred to as testing probability or statistical probability and the probability estimated by many experiments, is represented with P values.Specifically
For, P values represent the number percent for having a certain characteristic individual in experimental population, and it, which is reflected, has a certain spy in experimental population
Levy the appearance possibility size of individual.
The objective statistical that the probability of chance event shows part of getting over is regular, and it reflects event and occurred in once testing
The size of possibility, the possibility that the big expression event of probability occurs is big, and the possibility that the small expression event of probability occurs is small, if event
The probability that A occurs is smaller, and such as 0.05 or 0.01, then it is assumed that event A is unlikely to occur in once testing, and this is referred to as small probability
It is actual can not possibly occurring principle, abbreviation small probability principle, here 5% or 1% be referred to as small probability standard.
The screening technique and its screening plant have the comprehensive life of optimal cultivation suitable for each growth phase of consortive group of flora brown croaker
Produce selecting for the high-quality colony of performance.
The content of the invention is in order to overcome the group directional selection mode in current brown croaker seed selection using single traits as selection target
In the presence of the defects of, the present invention provides the artificial screening method and its screening dress of a kind of a kind of brand-new high-quality colony of brown croaker
Put, by the way of fish " the broken fish of net escapes " characteristic and weight gain performance screening are combined, using brown croaker consortive group of flora large sample as screening
Object, the high-quality colony of brown croaker with the comprehensive production performance of optimal cultivation is filtered out in the case where pushing up stream mode, to realize that screening is obtained
