Under conditions of 27 t, pH 8.0 and salinity 33, we studied the method of latent infection of white spot syndrome virus ( WSSV) in Penaeus japonicus by nested-PCR and dot blot hybridization.

The larger infant Penaeus japonicus with about 3 cm lenghth were fed in two tanks at our laboratory for about 60 days without exchanging the sea water.

我们将约3厘米的日本对虾苗进行实验室模拟内陆养殖，发现不换海水经过约60天养殖可生长到约7厘米。
