中文摘要:
      在我国黄河流域、长江流域及珠江流域三个农业生态区,山东青岛、上海、浙江湖州及广州四个地区,在网箱、水泥池及池塘三种水体,单养或混养系统里,对五个尼罗罗非鱼品系,即吉富品系、“78”品系、“88”品系、“埃及”品系以及“美国”品系,进行生长性能的评估。评估分一龄和二龄阶段跟踪进行,共十七个试验。生长性能试验结果证明,不论是在青岛、湖州、上海还是在广州,不论是池塘、水泥池、还是网箱养殖,不论是混养还是单养,是在苗种阶段还是在成鱼阶段,生长速度依次为:吉富品系>“88”品系>“78”品系>“美国”品系>“埃及”品系。未发现尼罗罗非鱼品系间生长速度差异有何表型—环境互作效应。
