Embodiment 1
[0023] Select 8 parent shellfish of Pinctada grandis and use this method to induce spawning and culture, start ripening and fattening in the ripening culture pond, and carry out in the indoor cement pond, the pool water is sand filtered seawater, add seawater to a depth of about 1 meter, and the water temperature is 28°C. Hang and raise the mother-of-pearl oysters inside to enhance ripening, and feed three times at 8:00 am, 3:00 pm, and 10:00 pm at regular intervals. The amount of bait fed is 6,000 flatweeds / ml, 30,000 golden algae / ml and spirulina powder 3.5ppm, and a full water change was carried out every 3 days during the ripening culture period. Take four 30w ultraviolet lamps at 2:00 pm on the seventh day of the ripening culture, seal the joints at both ends, put each two in an 80L bucket, fill up with filtered seawater, so that the ultraviolet lamps are completely submerged in seawater, The two lamps work alternately, and the ultraviolet irradiation time is about 18 hou...
Embodiment 2
[0025] Select 18 mother-of-pearl oysters and use this method to induce spawning. After cleaning, put them in a cement pond with a water depth of about 1m for temporary breeding. Algae, one died during the holding period. After raising temporarily for a week, put them into the fattening pool to start fattening. It is carried out in the indoor cement pool. The cement pool is first sterilized by 0.1% potassium permanganate. The pool water is sand-filtered sea water. 29.5°C (slightly higher than the outdoor water temperature), hang the mother-of-pearl oyster inside to strengthen ripening, feed three times at 8:00 am, 3:00 pm, and 10:00 pm at regular intervals, and the amount of feeding is 6000 flat algae / ml , golden algae 30,000 / ml and spirulina powder 3.5ppm, during the ripening period, a full water change was performed every 3 days. On the 9th day of ripening culture, take four 30w ultraviolet lamp tubes at one o'clock at noon, and seal the joints at both ends. Put each two tub...
Embodiment 3
[0027] Use this method to induce spawning for 28 ivy. After cleaning up, put them in a cement pool with a water depth of 1m for temporary cultivation. The water temperature is 28.4°C. Feed twice a day, and 2000 flat algae / ml are fed. After 5 days of temporary cultivation, take it out and put it in an indoor cement pool for enhanced ripening. The cement pool is first sterilized with 0.1% potassium permanganate, then put in sand-filtered seawater, add seawater to a depth of about 1 meter, and the water temperature is 28.5°C , hang and raise the eel shellfish in it for temporary breeding and ripening, and regularly feed three times at 8:00 am, 3:00 pm, and 10:00 pm. The algae powder is 3.5ppm, and the water is changed every three days during the ripening period. At noon on the 10th day, take six 30w ultraviolet lamps, seal the joints at both ends, put each two in an 80L bucket, fill up with filtered seawater, make the ultraviolet lamps completely submerged in seawater, and the tw...
