Abstract
The invention provides a artificial breeding method for Mytilus coruscus, which comprises the step of larval breeding with the water temperature of 14-21 DEG C and the salinity of 25-28. Water is changed once through siphonage or a method of discharging water from the bottom of a pool in the morning every day, and the total water change volume is gradually increased from 30 percent to 50 percent; bait is taken as algae and fed twice every day, namely, being fed once after water change in the morning, and being fed once more in the evening according to the density of algae in the cultivating water body, so as to satisfy the requirement on algae density. The method provided by the invention has the advantages that as the prior art is further researched, the requirement on water temperature in the larval breeding step is decreased, and the breeding process is more reasonable by optimizing other parameters, therefore, compared with the prior art, the energy consumption is low, and the bred young Mytilus coruscus is strong.
Description
Technical field
The present invention invention be a kind of method of Trachyostracous mussel artificial breeding, the method for larval culture especially wherein belongs to the breeding technology field of fish in the essential agricultural of human lives.
Background technology
Mussel is under the jurisdiction of Mollusca, lamellibranchiata, mussel order, Mytilidae, and mussel belongs to, and is the marine products bivalve shellfishs, and paddy claims blue or green mouthful, Hai Hong, and its dried product claims mussel, and very high nutritive value is arranged, and also has well medicinal and dietotherapy effect.The edible mussel that coastal area of china produced mainly contains Mytilus galloprovincialis, Trachyostracous mussel and Perna viridis etc.Wherein, Trachyostracous mussel is individual big, and nutrition is good, is worth higherly, existingly gathers the history that wild seed is implemented breed for many years.For a long time, the seed of Trachyostracous mussel relies on wild collection and a spot of natural spatfall, and seed quantity can not satisfy the breed needs, and fluctuation is very big again.People have carried out the key technology that long term research attempts to break through the Trachyostracous mussel artificial breeding for this reason, have just introduced this achievement in research as Chinese invention patent application " a kind of artificial nursery stock growing method for thick-shell mussel " (publication number CN101317549).This method mainly contains A, close shellfish hot housing, B, hastens parturition, adopts ovum hatching, C, larval culture, and steps such as D, juvenile mollusk cultivation, " wherein the condition of larval culture is: 21.0 ~ 23 ℃ of water temperatures, day quantity of exchanged water 30% ~ 100%; Day is changed water 1 ~ 2 time; Salinity is 25 ~ 30, and pH value is 7.8 ~ 8.2, and dissolved oxygen content is more than the 5mg/L, and ammonia-nitrogen content is below the 0.2mg/L, and intensity of illumination is 500LX ~ 1000LX, continuous charge, bait is one or both in Isochrysis galbana, the flat algae ".It is higher that this method requires to bring up water temperature, and common thick shell is made a gift of growing seedlings of shell and carried out in spring, and therefore also not enough this method requirement of temperature this moment needs artificial the intensification for the used water body of larval culture.For the needed a large amount of water of larval culture, although the temperature difference that is promoted is not that the very big energy that consumes also is many.
Summary of the invention
At above-mentioned deficiency, technical problem to be solved by this invention is how to finish the larval culture process in the low water temperature of trying one's best, and proposes a kind of method of new Trachyostracous mussel artificial breeding.
The method of Trachyostracous mussel artificial breeding provided by the invention comprises the larval culture step, and this step is carried out in cultivating the pond, water temperature is 14 ~ 21 ℃, and salinity is 25 ~ 28, and the pH value is 8.0 ~ 8.2, dissolved oxygen content is more than the 5mg/L, and ammonia-nitrogen content is below the 0.2mg/L, and intensity of illumination is 500 ~ 1000LX; Morning every day with siphonage or pond at the bottom of drainage change water 1 time, total quantity of exchanged water increases to 50% gradually from 30%; With the algae is bait, and day bait throwing in 2 times is thrown something and fed 1 time after promptly changing water morning, at dusk according to the density of cultivating algae in the water body, replenishes and throws something and feeds 1 time, the kind of the algae of throwing something and feeding and throw something and feed and cultivate the density requirements that algae will reach in the water body when finishing and see the following form:
| The paedomorphosis stage | Algal kind | Density (ten thousand cell/ml Chi Shui) |
| The D type young | Chrysophyceae, diatom, chlorella | 1~3 |
| The shell top young | Chrysophyceae, diatom, chlorella | 2~6 |
| The eyespot young | Chrysophyceae, diatom, chlorella, flat algae | 4~10 |
| The young crawls | Chrysophyceae, diatom, chlorella, flat algae | 4~10 |
In the whole process, per 4 ~ 5d falls pond 1 time, continues inflation.
The method of Trachyostracous mussel artificial breeding provided by the invention has been done further research to prior art, makes the water temperature in the larval culture step wherein require to descend, and by preferred other parameters, make cultivating technique more reasonable, compared with prior art, energy consumption of the present invention is low, the young seedling of gained is strong.
Embodiment
The close shellfish hot housing of having grown seedlings of Trachyostracous mussel, hasten parturition, adopt steps such as ovum hatching, larval culture, juvenile mollusk cultivation.Wherein in the larval culture step:
Breeding condition: 14 ~ 21 ℃ of water temperatures, salinity 25 ~ 28, pH8.0 ~ 8.2, more than the dissolved oxygen 5mg/L, below the ammonia nitrogen 0.2mg/L, illumination 500 ~ 1000LX.
Change water: morning every day with siphonage or pond at the bottom of drainage change water 1 time, total quantity of exchanged water increases to 50% gradually from 30%.
Bait: chrysophyceae, diatom, chlorella and flat algae, day bait throwing in 2 times is thrown something and fed 1 time after promptly changing water morning, at dusk according to the density of cultivating algae in the water body, replenishes and throws something and feeds 1 time.Each stage bait combination of the young and feeding volume (representing) with the density that the algae of cultivating in the water body reaches:
| The paedomorphosis stage | Algal kind | Density (ten thousand cell/ml Chi Shui) |
| The D type young | Chrysophyceae, diatom, chlorella | 1~3 |
| The shell top young | Chrysophyceae, diatom, chlorella | 2~6 |
| The eyespot young | Chrysophyceae, diatom, chlorella, flat algae | 4~10 |
| The young crawls | Chrysophyceae, diatom, chlorella, flat algae | 4~10 |
Fall the pond: in seedling raising process, per 4 ~ 5d falls the pond once.
Inflation: continuous charge in the larvae cultivation process, along with larval growth, strengthen aeration quantity gradually.
Diseases prevention: irregularly working concentration is the penicillin of 1 ~ 2mg/L.
