The invention discloses a method suitable for artificial breeding of
CrassOstrea hongkongensis in a sea area in the north. The method suitable for artificial breeding of
CrassOstrea hongkongensis in the sea area in the north is characterized by comprising the steps that firstly,
CrassOstrea hongkongensis adult
shellfish with a shell higher than 10 cm are selected, the
CrassOstrea hongkongensis adult
shellfish are placed in breeding ponds in high-temperature summer (July and August) with the density of 40-50 pieces / m<3> under the conditions that the
water temperature ranges from 26 DEG C to 30 DEG C and the
salinity ranges from 25 to 32, artificial oviposition and spermiation are conducted after the
CrassOstrea hongkongensis adult
shellfish are bred for 10 days to 15 days, spawn and sperms are placed in a breeding pond containing filtered sea water to be discharged naturally after being dried in the shade for five hours to eight hours, or the spawn and the sperms are obtained after the male shellfish and female shellfish are distinguished manually, and then
artificial insemination is conducted; germ cells are hatched for 18 hours to 20 hours under the condition that the
water temperature ranges from 26 DEG C to 32 DEG C so that D type larvas can be obtained, the D type larvas are placed in ponds to be bred with the density of 6-8 pieces / m<3>, when 50%-80% of the D type larvas become eyespot larvas after the D type larvas are hatched for 15 days to 18 days,
oyster shell and
cement block substrata are placed into the ponds, and
juvenile mollusk is obtained after the eyespot larvas adheres to the
oyster shell and
cement block substrata for four days to six days; finally, the
juvenile mollusk adhering to the
oyster shell and
cement block substrata is moved into outdoor ponds to be bred, the
juvenile mollusk is transported to a sea area in the south to be bred in an overland mode at lower temperature after the juvenile mollusk is 5 mm-10 mm long. By the adoption of the method suitable for artificial breeding of
CrassOstrea hongkongensis in the sea area in the north, the problems that the rate of fertilization for artificial breeding of the CrassOstrea hongkongensis in the south is low and the
survival rate of the larvas is low are solved.
