Embodiment 1
[0030]At the beginning of May 2012, the new strain of scallop "Bohai Red", which was nearly mature in gonads, was brought into the nursery room, and the gonads matured after a week of maturation using the conventional bay scallop seedling maturation method. Stimulate scallop oviposition with dry dew plus temperature stimulation, cultivate larvae according to the conventional culture method of bay scallop larvae, put plastic attachment base when 30-50% of larvae appear eye spots, and continue to cultivate for about 15 days after larvae metamorphosis. When the shell is 0.5 mm high, put it in a 60-mesh seedling preservation bag and directly transfer it to the Laizhou sea area for seedling preservation. After 2 weeks of seedling preservation, the seedlings were separated from the mesh, and transferred to 40-mesh mesh bags at a density of 3000-4000 per bag to continue cultivating. After about 30 days of cultivation, they are transferred to 20-mesh temporary cages at a density of 1,...
Embodiment 2
[0032] The "Qingnong No. 2" scallop seed raised in Laizhou, Shandong in March 2014 was cultured in the sea area of Laizhou, Shandong. When the shell height reached about 2.4 cm in early August, it was airlifted to Xiamen and then cultured in Dongshan sea area. The height reaches about 6.4 cm, and the survival rate is about 65%.
