Abstract
The invention provides a method for artificially protecting the seedlings of the mytilus coruscus. The method comprises the following steps of: putting the juvenile mytilus coruscus into a net piece bag in the early temporary cultivation, suspending the net piece bag into the sea water with the depth of 3+/-0.4m, and leading the net piece bag to have no adherent sludge and the other attachments; dispersing the mytilus coruscus seedlings which are adhered to one another after the temporary cultivation, washing off the floating sludge out of the mytilus coruscus seedlings and the harmful living beings, and packing the seedlings, wherein the density is thick rather than overlapping, and the pressure of the net piece to the juvenile seedlings is controlled such that the juvenile seedlings are not accumulated in the net piece bag when the seedlings are packed; and removing the net piece after the seedlings are packed, continuously performing the later temporary cultivation, and harvesting the seedlings after the temporary cultivation. The method for artificially protecting the seedlings of the mytilus coruscus is preformed in the sea water with a proper depth, and leads the juvenile seedlings to grow in the environment which is smooth in water flow and small in sludge and miscellaneous algae disoperation by measures, so that the survival rate is more than 50%, specifically the survival rate is improved by at least 8% compared with the prior art.
Description
Technical field
What the present invention relates to is the method that a kind of Trachyostracous mussel is manually kept a full stand of seedings, and belongs to the cultural technique 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 produces mainly contains Mytilus galloprovincialis, Trachyostracous mussel and Perna viridis etc.Wherein, Trachyostracous mussel is individual large, and nutrition is good, is worth highlyer, existingly gathers for many years wild seed and implements the history that cultivates.For a long time, the seed of Trachyostracous mussel relies on wild collection and a small amount of natural spatfall, and seed quantity can not satisfy the cultivation needs, and fluctuation is very large again.Through long-term tackling key problem research, Trachyostracous mussel seed breeding key technology breaks through, but also exists juvenile mollusk to have the low defective of survival rate in the process plunging into the commercial sea to keep a full stand of seedings.
Summary of the invention
For this defective, technical problem to be solved by this invention is to propose a kind of method that the young seedling of Trachyostracous mussel is manually kept a full stand of seedings at marine Trachyostracous mussel of keeping a full stand of seedings the phase survival rate that improves.
The method that Trachyostracous mussel provided by the invention is manually kept a full stand of seedings, carried out before this supporting temporarily early stage and carried out again Bao Miao, carrying out at last the later stage supports temporarily, it is that the juvenile mollusk that will finish the stage of growing seedlings is contained in the net sheet bag and hangs in the seawater that its mid-early stage supports temporarily, Bao Miao is that the juvenile mollusk that will finish to support temporarily is wrapped in Miao Shengshang with the net sheet with juvenile mollusk, remove the net sheet after the bag seedling finishes, it is that the continuation that removes behind the net sheet is supported temporarily that the later stage supports temporarily, and gathering after foster temporarily is seed; The degree of depth that is suspended in the seawater when supporting temporarily said early stage is 3 ± 0.4m, keeps outer mud and other attachment without adhering to of net sheet bag; Will scatter the spat that mutually adheres at said Bao Miaoqian, and the outer mud scum of flush away spat and harmful organisms, it is close and not overlapping grasping density during the bag seedling, the net sheet to the pressure of young seedling so that it is piled up as degree in net sheet bag.
Said early stage, used net sheet bag was that 40 order nylon cloths are made when supporting temporarily, and the length of side is 30 ~ 40cm, and the juvenile mollusk size of throwing in is at 2 ± 0.2mm, and injected volume is to throw in juvenile mollusk 2 ± 0.02 ten thousand in each net sheet bag.
The time that support temporarily said early stage is 1 month, or the juvenile mollusk size finishes when reaching 4 ± 0.4mm.
Bag seedling density during said bag seedling is 2 ± 0.02 ten thousand juvenile mollusk/bar seedling ropes.
The time of said Bao Miao is 9 ~ 12 days, fastens at the seedling rope as degree take refined byssus.
The time that later stage supports temporarily is 3 ~ 4 months, or the juvenile mollusk size finishes when reaching harvesting standard.
The method that Trachyostracous mussel provided by the invention is manually kept a full stand of seedings, to keep a full stand of seedings and carry out in sea water advanced suitable, and take measures to make that young seedling is unimpeded at current, grow in the environment that mud and assorted algae infringement are few, survival rate is reached more than 50%, compared with prior art, improve at least 8%.
Embodiment
The method that a kind of Trachyostracous mussel is manually kept a full stand of seedings was carried out before this supporting temporarily and was carried out Bao Miao again early stage.
1, support temporarily early stage:
2.5 hundred million of juvenile mollusks, specification 1.8 ~ 2.3mm packs in the 40 order nylon mesh sheet bags of 30 cm * 40cm size by throwing in 20,000 meterings of juvenile mollusk in each net sheet bag.Hang take 10 bags as one, the polyethylene rope that whenever hangs with diameter 0.4cm, long 3m is hung on floating well rope.After this often clean gently seedling bag outside shale and other attachment, make the seedling bag remain that current are unimpeded, guarantee normal growth.After the juvenile mollusk size reaches 4 ± 0.4mm, progressively divide seedling to carry out Bao Miao after 1 month.
2, Bao Miao:
(1) first spat is processed, namely the spat that mutually is attached together is scatter, and flush away spat surface mud scum and harmful organisms is to strengthen adhesive strength.
(2) with 20 order plastic deepings juvenile mollusk is wrapped in Miao Shengshang,
A. the bag seedling quantity of every seedling rope is with 20,000 meterings.Bag seedling density is excessive, crowded growth, and attachment surface comes off in the middle of reducing formation.Bag seedling density is excessively rare, the mud scum alluvial, and assorted algae grows thickly, and causes juvenile mollusk by mud and assorted algae parcel, and the normal growth and the byssus that affect juvenile mollusk are aging, and autotomying comes off.
B. net sheet tense-lax is suitable, and juvenile mollusk is piled up as degree in the unlikely net sheet.Too tight spat is difficult for adhering to, and too pine causes spat to pile up.
3, the later stage supports temporarily:
The bag seedling net sheet of dismantling after 10 days, through 115 days holding culture offshore, gathering obtained seed.
Can support seed size through the actual measurement gained and on average reach 1.5cm; The survival rate of keeping a full stand of seedings reaches 52.2%.
