日本对虾(P.japonicus)是在中国对虾(P.chinensis)连年遭受病害以后,由东南沿海引进而来。该虾种广温、广盐、养殖周期短、离水存活时间长,很快被北方地区沿海养殖推广起来。经过几年的不断探索,已基本掌握了其生长特性与生活习性,使该虾的养殖逐步形成规模化和产业化,弥补了北方地区虾类养殖的产量,其经济效益也十分可观。本文通过日本对虾与中国对虾的养殖生产的有关资料,采用等量对比的方式,分析两个虾种在养殖生产上的经济效果,借此提出对今后养殖生产及其技
P. japonicus was introduced from the southeast coast after P. chinensis suffered from diseases year after year. The shrimp wide temperature, wide salt, short breeding cycle, survival time from the water long, and soon to promote coastal culture in the north up. After several years of continuous exploration, it has basically mastered its growth characteristics and habits, so that the shrimp farming gradually formed scale and industrialization, to make up for the northern shrimp farming output, the economic benefits are also very impressive. In this paper, the relative data of shrimp culture of Penaeus chinensis and Penaeus chinensis were compared by the way of the same quantity to analyze the economic effects of two shrimp species on the farming production,
