Abstract
The invention discloses a breeding method for shortening float periods of urechis unicinctus larvae. The breeding method particularly includes feeding isochrysis 3011 to the urechis unicinctus larvae from the third day to the seventh day after the urechis unicinctus larvae are fertilized, and keeping the temperatures at 15.5-16 DEG C; keeping the water temperatures at 16.5-17 DEG C from the seventh day to the twelfth day; keeping the water temperatures at 17.5-18 DEG C from the thirteenth day to nineteenth day and changing 1/2 volumes of water twice on a daily basis; feeding feed four times on a daily basis from the seventh day to nineteenth day. The isochrysis 3011 is initial feed, and the feeding quantities of the initial feed is 40ml/m<3>d. Formulas and usage quantities of the feed in different procedures from the seventh day to nineteenth day are different from one another. The breeding method has the advantages that the metamorphosis and settlement time of the urechis unicinctus larvae in the float periods can be shortened, breeding periods can be shortened by 15-25 days as compared with schemes in the prior art, and the breeding cost can be reduced to a great extent.
Description
Technical field
The invention belongs to mariculture technical field, be specifically related to a kind of cultural method shortening the Urechis uniconctus larva pelagic period.
Background technology
Urechis uniconctus (Urechis unicinctus) is commonly called as extra large intestines, belong to Echiuroidea (Echiuroide), Yi guiding principle (Echiurida), without pipe Yi order (Xenopneusta), thorn Yi section (Urechidae).There is high economic worth, its body wall is except as except seafood, pole promises to be the raw material extracting Ocean Medicinal active substance, research shows that polypeptide that Urechis uniconctus extracts has the effect of certain antitumor and raising immune function of mice, also someone did separation and purification and the pharmacodynamic study of Urechis uniconctus antithrombotic component, and therefore Urechis uniconctus is also a kind of good material studying marine biomaterial.
Due in recent years because catching intensity is excessive, wild resource is inadequate.Now, China has also carried out the yielding ability research of Urechis uniconctus artificial culture seed successively: " Chinese Fishery " third phase in 2007 " Urechis uniconctus artificial breeding technique main points ", " Shandong fishery " first phase in 1997 " research of Urechis uniconctus artificial breeding technique ", " Qingdao Marine University's journal " second phase in 2002 " artificial seed's PRODUCTION TRAITS-water temperature of Urechis uniconctus is on the impact of embryonic development and larval culture ".But the pelagic period of prior art Urechis uniconctus larva reaches about 50 days, larger difficulty is brought to the management work that large area nursery is produced, add seedling cost, the invention provides a kind of cultural method shortening the pelagic period, yet there are no relevant report.
Summary of the invention
The present invention aims to provide a kind of cultural method shortening the Urechis uniconctus larva pelagic period, shortens the pelagic period of Urechis uniconctus larva, foreshortens to 20 days from 50 days, reduces the cost of larvae cultivation phase to a great extent.
The present invention realizes especially by following technical scheme:
Shorten the cultural method of Urechis uniconctus larva pelagic period, be specially Urechis uniconctus larva after fertilization the 3rd day to the 7th day, open-mouthed bait Isochrysis galbana 3011 of throwing something and feeding, bait feeding amount is 40ml/m
3d, larval density is 1 ~ 2/ml, and temperature remains on 15.5 ~ 16 DEG C, changes water twice day, changes water 1/2 volume at every turn.
Cultural method of the present invention, also comprise the 7th day to the 12 day, water temperature remains on 16.5 ~ 17 DEG C, 13 day to the 19 day, water temperature remains on 17.5 ~ 18 DEG C, changes water twice day, changes water 1/2 volume at every turn, Sinl'Perca chuatsT is during this period simultaneously: bait throwing in every day four times, and first time is Isochrysis galbana 301160ml/m
3+ 0.5g ocean rhodotorula dry powder/m
3, second time is Chaetoceros 60ml/m
3+ 0.5g ocean rhodotorula dry powder/m
3, third time is salt algae 60ml/m
3+ 0.5g ocean rhodotorula dry powder/m
3, the 4th time is Nitzschia closterlum 60ml/m
3+ 0.5g ocean rhodotorula dry powder/m
3.
Cultural method of the present invention was cultivated through 20 days, and 30% larval metamorphosis is vermiform larva, started abnormal attachment, all abnormal attachments afterwards in 25 days of being fertilized.
Beneficial effect of the present invention is compared to existing technology, and utilize cultural method of the present invention can reduce the time of Urechis uniconctus larva pelagic period metamorphosis attachment, comparatively prior art shortens 15 ~ 25 days nurturing periods, and high degree decreases cultivation cost.
