Embodiment 1

[0012] A breeding method for shortening the planktonic period of the larvae of Echinococcus monoringensis. Specifically, from the third day to the seventh day after fertilization, the open bait is fed with Isoflagellates 3011, and the amount of bait fed is 40ml / m 3 d. The density of larvae is 1-2 / ml, the temperature is kept at 15.5-16°C, and the water is changed twice a day, 1 / 2 volume of water is changed each time.

[0013] The breeding method of the present invention also includes keeping the water temperature at 16.5-17°C from the seventh day to the twelfth day, maintaining the water temperature at 17.5-18°C on the thirteenth day to the nineteenth day, and feeding the bait: Feed four times a day, the first time is Chrysopsis 301160ml / m 3 +0.5g marine red yeast dry powder / m 3 , the second time is Chaetoceros 60ml / m 3 +0.5g marine red yeast dry powder / m 3 , the third time is Salina 60ml / m3+0.5g marine red yeast dry powder / m 3 , and the fourth time is Nitzschia small cresc...

Embodiment 2

[0016] At 150m in mid-October 2013 3 In the nursery water body, the larvae of the single-ringed weedle are cultivated in this way, adopting the same breeding method as in Example 1, and the larvae begin to metamorphose into benthic life worm-like larvae after 20 days of cultivating, and all metamorphosis after 25 days. According to experts' acceptance, 30 million juveniles were obtained, and the overall metamorphosis survival rate was over 50%.

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 [0001] The invention belongs to the technical field of marine organism cultivation, and in particular relates to a cultivation method for shortening the planktonic period of the larvae of Echinococcus monoringensis. Background technique [0002] Urechis unicinctus, commonly known as sea intestine, belongs to the phylum Echiuroide, class Echiurida, order Xenopneusta, and family Urechidae. It has extremely high economic value, and its body wall is not only used as seafood food, but also has great potential as a raw material for extracting marine medicinal active substances. Studies have shown that the peptides extracted from Echinococcus monocysticum have certain anti-tumor and immune function-improving effects in mice. Some people have also done the separation, purification and pharmacodynamics of the anti-thrombotic components of C. unicycle. Therefore, C. unicycle is also a good material for the study of marine biological active substances. [0003] Due to ...
