Description
Technical field
The present invention relates to a kind of cultivation of the large nacre young, and in particular to a kind of raising large nacre metamorphosis
Method, belongs to technical field of shellfish culture.
Background technology
Settlement and metamorphosis are one important growth courses of ocean bivalve shellfish, and floating larva loses in this growth course
Face, set life is changed into from life of swimming.Attachment base is one of key factor of influence bivalve shellfish metamorphosis.It is existing
Species, material and color there are some researches show the attachment base of attachment base etc. have obvious shadow to the distortion ratio of the bivalve shellfish young
Ring, such as using dark colour（Black and brown）Attachment base can improve the distortion ratio of the young.In addition, research show metal from
Son, amino acids, neural activity amine chemical substance induction larval metamorphosis.Biomembrane main component is that microbe colony is dwelt the bottom of with
Diatom.Existing research reports microbial film and there is obvious influence to the attachment of the ocean bivalve young and metamorphosis process, wherein can
Energy reason is that biomembrane can discharge chemical substance, induces larval metamorphosis.
Large nacre is a kind of tropical seashells, mainly moves in the torrid zone, subtropical zone sea area, and NATURAL DISTRIBUTION is in the big profit of Australia
The states such as Asia, Philippine, Malaysia, Indonesia it is tropical coastal.Large nacre is for cultivating the main of sea water pearls
One of shellfish, the pearl particles of cultivation are big（More than 10mm）, pearl thickness, lovely luster, almost occupy whole high-grade both at home and abroad
Pearl market.The maximum country of external cultured output is Australia, Indonesia and Philippine, wherein the product of Australia
Value highest, accounts for the 50% of world's South sea Pearl output value.In China, large nacre distribution is from Beibu Bay of The South China Sea northeast edge
Lezhou Peninsula coastal waters is gone down south, and crosses Qiongzhou Strait, coastal around whole Hainan Island, until the Xisha Islands.The eighties in last century,
China's successful incubation large nacre nucleated pearl, but due to large nacre artificial sprout, in sea area, cultivation is survived to the female shellfish that can plant core
Rate is very low, does not reach 1%, it is impossible to which batch is obtained plants core mother shellfish, seriously governs China's large nacre and commercially produces.In order to carry
Large nacre cultivation survival rate high, Domestic Scientific Research worker has carried out larval culture and sea area cultural technique research, has improved greatly
The method of nacre metamorphosis is urgently studied.
The content of the invention
It is an object of the invention to provide a kind of method for improving large nacre metamorphosis, by the use of palm rope as attachment
Base, makes attachment primary surface form one layer of biological mould by immersion treatment, induces larval metamorphosis, significantly improves the large nacre young
Distortion ratio.
To realize the purpose of foregoing invention, the technical scheme that the present invention takes is as follows：
A kind of method for improving large nacre metamorphosis, comprises the following steps：
（1）Palm rope is soaked with 1% liquor potassic permanganate 10-12 hours, then using freshwater soaking 10-12 hours, cleaning residual
Liquor potassic permanganate；
（2）Palm rope is placed in into outdoor tank-culture to soak 1-2 days, nature seawater is continuously added in immersion process, after immersion terminates,
The sludge impurity that palm rope adheres to is removed using filtering sea；
（3）The ratio of nursery pond eyebot larvae is 50-70%, delivers palm rope；
（4）5-7 days after young settlement and metamorphosis, palm rope is transferred to another nursery pond and is cultivated；
（5）The seed size of palm rope reaches 2-3mm, and attachment base is placed in into 80 mesh mesh bags, transfer natural waterses cultivation.
Step（1）Described palm rope length specification is 70-100cm, diameter specifications 2-3cm.
Step（2）Described seawater addition 10-15L/min.
Step（3）The quantity that described palm rope is delivered is according to the determination of nursery pond young density, young density 0.5-1.0
Individual/mL, supply volume 20-30/m3。
The beneficial effects of the invention are as follows：
（1）With palm rope as attachment base, attachment primary surface is set to form one layer of biological mould by immersion treatment, the young becomes for induction
State, is the suitable attachment base of pearl shell because palm rope has relatively rough fibre structure, can significantly improve the metamorphosis of the young
Rate.
（2）Plastic plate is the traditional attachment base of pearl shell, when seed size reaches 2-3mm, by seed under attachment scrubbing brush
Come, be then transferred to sea area cultivation, due to mechanical injuries reduction weed survival rate.By the use of palm rope as attachment base, it is not necessary to
Seed is brushed down, palm rope is directly placed in mesh bag, be transferred to sea area cultivation, it is thus possible to improve seed cultivation survival rate.
（3）Palm rope price, by the use of palm rope as attachment base, can reduce production cost than relatively low, and easy to operate,
Easily promote.
