1 “超大规格超高效益”的概念 这里所说的“超大规格”指的是生物学体长14～18cm的对虾。自从1993年对虾暴发病毒病以后,北方养殖中国对虾一般6月中旬到7月发病出池,对虾的生物学体长一般在6～12cm,我们把这一体长范围的中国对虾称小规格虾。目前在一定单产情况下,其规格达到生物学体长12～14cm,这可以认为是大规格虾。因此,我们把14～18cm的虾称超大规格虾。
1 “super-large size ultra-high efficiency” concept Here, the “super size” refers to the biological length of 14 ~ 18cm shrimp. Since the outbreak of virus in shrimp in 1993, the shrimp in the north usually produce ponds in mid-June to July. The biological length of shrimp is generally 6-12cm. We call this shrimp, a small-scale shrimp of this body length range. At present a certain yield, the size of its biological biology reached 12 ~ 14cm, which can be considered a large size shrimp. Therefore, we call 14-18cm shrimp large size shrimp.
