大连地区仿刺参养殖池塘叶绿素a分布和初级生产力估算

The Distribution of Chlorophyll-a Content and Estimation of Primary Productivity in Sea Cucumber Apostichopus japonicus Culture Ponds

于2007、2008年每年的3—11月,对大连沿海地区的仿刺参养殖池塘叶绿素a含量进行了调查,并对初级生产力进行了估算。结果表明,大连沿海各地区的仿刺参养殖池塘中叶绿素a年均含量为2.11～5.40 mg/m3,最高值出现在2007年8月的庄河,平均值为12.96 mg/m3,最低值出现在2007年3月的旅顺附近,平均值为0.17 mg/m3。仿刺参养殖池塘中初级生产力的年均值为111.38～272.58 mg/(m2.d),最高值出现在2007年6月的瓦房店复州湾地区,平均值为602.72 mg/(m2.d),最低值出现在2007年3月的旅顺附近,平均值为16.47 mg/(m2.d)。

The chlorophyll-a contents were monitored and the primary productivity was estimated in the sea cucumber Apostichopus j aponicus culture ponds near Dalian, China, from March to November in 2007 and 2008. The chlorophyll-a levels were ranged from 2.11 to 5.40 mg/m3in the culture ponds, the maximum of 12. 96 mg/m3 in Zhuanghe on Augest, 2007, and the minimum of 0. 17 mg/m3 in Lvshun on March, 200？. The primary productivity was varied from 111. 38 to 272. 58 mg/（m2 · d）in the culture ponds, the maximum of 602.72 mg/（m2 · d）in Fuzhouwan on November, 2007, and the minimum of 16.47 mg/（m2 ·d）in Lvshun on March, 2007.
