超大型珍珠养殖与育珠蚌的吊养量密切相关,适度的育珠蚌吊养量是获取超大型珠的关键技术参数之一。通过对比2010—2015年的试验数据,得到如下结果:在相同的养殖与管理条件下,在培育超大型珍珠时,育珠蚌的吊养量与其养殖成活率无直接相关性;最适育珠蚌的吊养量分别为1龄珠蚌0.59只/m~2、2龄珠蚌1.02只/m~2、3龄珠蚌1.26只/m~2、4龄珠蚌1.53只/m~2,但超大型珍珠的最佳吊养量为1.43只/m~2,最佳毛利润的吊养量为2.1只/m~2,最佳产投比的吊养量为0.82只/m~2,其产投比可达2.63。
Oversized pearl cultivation is closely related to the amount of pearl oyster, and proper pearl oyster cultivation is one of the key technical parameters for obtaining super-large beads. By comparing the experimental data from 2010 to 2015, the following results were obtained: Under the same conditions of culture and management, there is no direct correlation between the amount of culture of pearl oyster and the survival rate of aquaculture when cultivating super pearl; The mussels were the first-age pearl oyster 0.59 / m ~ 2, the second-generation pearl oyster 1.02 / m ~ 2,3-year-old pearl mussel 1.26 / m ~ 2,4-year pearl mussel 1.53 / m ~ 2 , But the best pearl yield was 1.43 / m ~ 2, the best gross profit was 2.1 / m ~ 2 and the best yield was 0.82 / m ~ 2, its production ratio up to 2.63.
