影响海湾扇贝中间育成效果的主要因素有:育成器具种类(A)、换袋时间(B)、网孔大小(C)和装苗量(D)。正交试验和方差试验表明,A、C、D为提高保苗率的敏感因素,B、C、D为提高生长效果的显著因素。试验结果提出:网箱或圆锥形袋的保苗率明显优于扁袋;每隔15～30天更换一次网袋可显著加快贝苗的生长速度,网孔大小以2mm为适宜,每袋最终实际装苗量应在2000只以内。
The main factors influencing the breeder performance in the Gulf scallop are: the types of breeding equipment (A), the time of bagging (B), the size of the mesh (C) and the amount of seedlings (D). Orthogonal test and variance test showed that A, C and D were the sensitive factors to improve the seedling protection rate, and B, C and D were the significant factors to improve the growth effect. The results showed that: the cage or conical bag seedling conservation rate was significantly better than the flat bag; every 15 to 30 days to replace a mesh bag can significantly speed up the growth of seedlings, the mesh size to 2mm as appropriate, the final actual bag Miao Miao amount should be less than 2000.
