【摘要】 在上海地区进行罗氏沼虾商品虾两茬养殖，关键是抓好早繁苗的中间培育和第二茬养殖用苗的囤养。采用温室保温、锅炉增温和气泵充气等技术措施对罗氏沼虾的早繁苗进行集约化中间培育，可以提前１个月，在５月１０日左右为商品虾的第一茬养殖培育出大规格虾苗。利用室外土池囤养晚苗，为第二茬养殖培育虾苗，重点应处理好饲料投喂与水质调节之间的矛盾。更多还原

【Abstract】 Intermediate culture of earlier seeds and temporary rearing of post larvae for second crop rearing are the key links for two crops rearing of commercial sized Macrobrachium rosenbergii in Shanghai region. If proper technical measures, such as maintaining the temperature in green house, increasing the temperature by using boilers and aeration throngh pumps, large sized post larvae could be produced for first crop adult prawn rearing on May 10, about one month earlier than the normal date. Temporary rearing of post larvae for second crop rearing was conducted in outdoor easthen ponds. The key point in this process was to resolve the contradiction between feeding and control of water quality.更多还原
