摘要
本文调查了在中国对虾养成过程中,放苗数,饵料系数和产量不同的七个虾池水体内叶绿素a的含量变化及五个虾池水体内脱镁叶绿素的含量变化。结果表明七个虾池中叶绿素a的含量从5月份到9月份由4mg/m3左右增加到37~46mg/m3,8月份个别虾池达到65mg/m3。五个虾池中的脱镁叶绿素含量从5月份到8月份由<10mg/m3增加到48~66mg/m3,和叶绿素a的变化是一致的,但9月份又下降到30mg/m3以下。
The variations of chlorophylla and phaeophytin during the adult culture of penaeus chinensis are investigated. The result shows that the content of chlor ophylla increases from about 4mg·m-3 to 37-46mg·m- 3, from May to September,reachs 65mg·m-3 in individual shrimp pond in August. the content of phaeophytin incre-ases from <10mg·m-3 to 48-66mg·m-3 from May to August.
