Background technique
Pteria martensii（Pinctada martensii）Also known as pinctada fucata is the main of China breeding seawater pearl
Shellfish kind is claimed " Nan Zhu " with the pearl that pteria martensii cultivates, and the pearl of production accounts for 90% or more of sea water pearls yield." south
Pearl " cultivation is the specialty industries of China's agricultural and the pillar industry of Guangdong Province Lezhou Peninsula coastal area, when peak to cultivate face
Product surpasses 5.38 ten thousand mu, and 4.5 ten thousand people are engaged in pearl sector, 20 tons of pearl annual output or so, accounts for 70% or more of national yield, is formed
Seedling fostering, female shellfish cultivation, plant core grow cultured pearls, one huge industrial chain of pearl processing and sale, the entire industrial chain gross output value
Up to billions of members, positive contribution is made that for shaking off poverty and setting out on the road to prosperity for Lezhou Peninsula coastal area peasant.
Currently, it is that breed variety is degenerated, breeding environment deteriorates and cultural technique is old that " Nan Zhu ", which produces existing main problem,
It is old, lead to that the pearly shellfish death rate is high, core-remaining rate is low, pearl quality is poor, " Nan Zhu " annual output only has 2-3 tons, and culture efficiency is substantially
Degree glides, and raiser changes one's profession or closes down one after another.For the predicament that south-pearl industry faces, Guangdong provincial people's government implements to revitalize south
There is slow recovery in pearl industry plan, pearl sector, but are faced with the problem of high-quality cultivation seedling insufficient supply.Geneva pearl oyster
During shellfish seedling fostering, nursery enterprise and nursery carry out artificial breeding by the way of not changing water and repeatedly launching collector,
Collector usually takes ability complete metamorphosis attachment in 6-10 days after launching, dead in nursery pond after being launched 5-7 days due to collector
Algae and the diatom newly grown, larva secretion and water body in bacterium etc. be adhered to and make to adhere on the lamina affixad of collector
Plate, which becomes, to be slided, and causes not yet abnormal larva cannot the abnormal attachment on lamina affixad；Secondly, even if the abnormal larva individual newly adhered to
It is small, cause out pond seedling size it is uneven；Third, if the attachment of eyebot larvae long-time unchangeable metamorphosis will natural death or logical
It crosses and changes water and exhaust, cause eyebot larvae utilization rate low.In order to improve nursery benefit, enough high quality seedlings are provided for raiser, are mentioned
The abnormal adhesive rate of high eyebot larvae seems particularly significant.
Summary of the invention
The present invention produces the low situation of existing eyebot larvae utilization rate for pteria martensii nursery, and providing one kind can
