The artificial fecundation method of a kind of soft coral
Technical field
The present invention relates to aquaculture field, particularly relate to the artificial fecundation method of a kind of soft coral.
Background technology
The karang that coral is formed has species diversity and important ecological functions. Research show healthy karang system every year every square kilometre of fishery output reach 35 tons, the fishery output in the whole world about 10% comes from karang area. Reef-building organism participates in the reef body formed, and is not only the 3 D stereo habitat that other happiness reef biology provides complicated, and has important anti-wave shore protection effect, for sea grass, mangrove forest and the mankind provide safe ecotope. In addition, karang has the title of " ocean tropical rain forest ", has 1/4 to live in this in whole world marine organisms, has and lives near karang (having an area of 30 kilometers/18 miles) more than 2.75 hundred million people. Coral reef ecologic system has extremely abundant Biological resources, is the extremely important breeding base of marine fishery, is safeguarding to have special critical role in marine biodiversity. For many years, karang suffer overfishing, illegally fish for, illegally excavate, not science port construction and do not protect the factors such as ocean exploitation so that existing distribution area and length sharply reduce, and strengthen karang protection extremely urgent.
Coral is divided into madrepore, soft coral and gorgonian morphological specificity. Soft coral belongs to Coelenterata, Anthozoa, from all directions coral subclass, soft coral order in classification, comprises and intends Alcyoniidae, Alcyoniidae, star pin Alcyoniidae, spine Alcyoniidae, brocade flower Alcyoniidae and different colored Alcyoniidae 6 sections. At present, it is known that soft coral has kind more than 1000 (coral investigation in Hainan finds that there is 110 kinds and 5 subspecies), and major part lives in Perenniporia martius neritic region. Soft coral colony morphology is various, has block shape, mushroom shape and just like the branch vegetal inspired of flowers and plants. The base portion of soft coral colony claims shank, and without polyp, top claims hat portion, is covered with polyp. The polyp of soft coral and colony all have many calcareous spicules usually, and spicule shape is different with kind, are generally long fusiform or clavate, and it has wart or excipuliform branch.
Due to soft coral, there is self-regeneration ability faster and there are the potentiality of drug development, therefore, by artificial fast-propagation, be expected to become more satisfactory extract drugs and restoration of the ecosystem kind.
Currently, except to wild coral more protection, carrying out coral artificial propagation is also an approach effectively saving coral. Wild coral parental generation is utilized to breed a large amount of offspring's corals through modern biology technology, the growing corresponding reduction to the demand of coral of people can be met to the dependence of wild coral, the coral bred is released simultaneously and can improve again the species diversity in marine site into sea, improving the ecotope in marine site and promote the sound development of related industries, the artificial propagation techniques research therefore carrying out soft coral is necessary very much.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the artificial fecundation method of a kind of soft coral.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the artificial fecundation method of a kind of soft coral, and concrete steps comprise:
1) attachment base is selected: select never to descend water to use or the attachment base of drying, attachment base is placed on table, the place of coral is fixed in selection, first with distilled water cleaning attachment base, after adhering to base surface dry, coat super glue in the place of glutinous coral, then by after coral set, being coated with last layer super glue film again, this thin film should than commissure a little greatly a bit;
2) preparation before branch is intercepted: being loaded by water respectively in two buckets, a bucket is used for putting the branch intercepted, and another barrel is used for putting the branch fixed;
3) son, maternal plant are split: the coral maternal plant lopping first will chosen, but bundle strain is not separated with maternal plant, whole strain soft coral is considered as a clock, 2 o'clock, 4 o'clock, 6 o'clock, 8 o'clock and 10 o'clock direction be switched to the 1/2 of trunk downwards, but it is not separated with trunk, then the environment that soft coral is placed in good water quality and current, after three weeks, cut surface will heal;
4) son, maternal plant are separated: after waiting all cut surfaces all to heal, so that it may sub-strain intercepted with sharp scissors;
5) breeding of sub-strain: the sub-strain intercepted is positioned in the bucket filling water, then attachment base and the point of fixity of sub-strain is selected to be put, sub-strain tangent plane facial tissue for being placed on attachment base is dried, and then super glue is coated on attachment base, then bundle strain sticks on point of fixity, again the sub-strain sticked is placed in bucket, retracts again in water vat after two minutes.
In a preferred embodiment of the present invention, the sub-strain extensive pedigree antibiotic solution that described step (4) intercepts carries out immersion treatment.
In a preferred embodiment of the present invention, described attachment base is karang or cement block.
The invention has the beneficial effects as follows: the artificial fecundation method of a kind of soft coral of the present invention implants science and technology in the process of growth of soft coral; soft coral is bred fast; to meet people to the demand of soft coral; solving soft coral cannot the problem of manual control in process of growth; soft coral is made to realize factorial praluction; while promoting Living marine resources artificial increasing cultivation, marine ecology reparation can be carried out again and protect corresponding ecotope.
Embodiment
Below the better embodiment of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made more explicit defining.
The embodiment of the present invention comprises: the artificial fecundation method of a kind of soft coral, and concrete steps comprise:
1) attachment base is selected: select never to descend water to use or the attachment base of drying; attachment base would not there is one layer of so-called microbial film; because microbial film can repel additional biology usually; described attachment base is karang or cement block; attachment base is placed on table, selects the place being fixed coral, if the coral to be added can have influence on the growth of contiguous coral; then need to consider its glutinous position put, and being placed in of as far as possible being balanced by coral is adhered on base. For speed of growth coral faster, it is possible to stick on bigger attachment base, the slow species of growth rate then can stick on less attachment base.
First with distilled water cleaning attachment base, after adhering to base surface dry, super glue is coated in the place of glutinous coral, then by after coral set, it is coated with last layer super glue film again, this thin film bigger a little than commissure a bit should be attached base absorption to take precautions against glue, and causes coral to engage bad with attachment base.
2) preparation before branch is intercepted: being loaded by water respectively in two buckets, a bucket is used for putting the branch intercepted, and another barrel is used for putting the branch fixed.
3) son, maternal plant are split: the coral maternal plant lopping first will chosen, but bundle strain is not separated with maternal plant, whole strain soft coral is considered as a clock, 2 o'clock, 4 o'clock, 6 o'clock, 8 o'clock and 10 o'clock direction be switched to the 1/2 of trunk downwards, but it is not separated with trunk, the environment that then soft coral is placed in good water quality and current, after three weeks, cut surface will heal.
4) son, maternal plant are separated: after waiting all cut surfaces all to heal, sub-strain is intercepted by available sharp scissors, the sub-strain extensive pedigree antibiotic solution intercepted is carried out immersion treatment, do not worry that the coral cut through can scatter, within several days, coral still can connect together, when coral starts outwards to scatter, its cut surface also starts to have healed.
5) breeding of sub-strain: the sub-strain intercepted is positioned in the bucket filling water, then attachment base and the point of fixity of sub-strain is selected to be put, sub-strain tangent plane facial tissue for being placed on attachment base is dried, and then super glue is coated on attachment base, then bundle strain sticks on point of fixity, again the sub-strain sticked is placed in bucket, retracts again in water vat after two minutes.
Compared with prior art; the artificial fecundation method of a kind of soft coral of the present invention implants science and technology in the process of growth of soft coral; soft coral is bred fast; to meet people to the demand of soft coral; solving soft coral cannot the problem of manual control in process of growth; make soft coral realize factorial praluction, while promoting Living marine resources artificial increasing cultivation, marine ecology reparation can be carried out again and protect corresponding ecotope.
The foregoing is only embodiments of the invention; not thereby the patent scope of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all it is included in the scope of patent protection of the present invention with reason.
