淡水肉食动物生物量和生产量的季节变化。Sagi/ a II i. pida。Conant和Mnemi/Jpsis merradili Mayer在亚热带近海海洋环境中被跟踪。产量估计为平均每日生物量（根据取样生物量和计算的死亡率计算）和每日生长率的乘积。后者是坚定的！d，在三个温度下进行了发酵培养试验。栉水母的生物量和生产量的季节性波动远大于毛颚类。卡湾和比斯坎湾的箭虫平均日生产量分别为2.00和4.80毫克/平方米，比斯坎湾的拟箭虫平均日生产量为1.01毫克/平方米。卡湾没有栉水母，可能是因为浮游动物现存量比比斯坎湾低一个数量级（exe！包括栉水母I.平均产量/生物量比分别为0.31和0.12。
Seasonal changes in biomass and production of t w', planktonic carnivores. Sagi/./a II i.pida. Conant and Mnemi/Jpsis merradili Mayer, were followed in a subtropical inshore marine em·ironment. Production was estimated as the product of mean daily hiomass (calculated from the sampled biomass and computed mortality rates) and daily growth rate. The latter was determinE!d from lahoratory culture experiments at three temperatures. Seasonailluctuations of ctenophore biomass and production were much greater than those of chaetognaths. Mean daily produl'tion in milligram carhon per square meter was 2.00 and 4.80 for Sagitta in Card Sound and Biscayne Bay respectively, and 1.01 for Mllrmiopsis in Biscayne Bay. The ctenophore was absent from Card Sound, possibl,\" hecause the zooplankton standing crop was an order of magnitude lower than in Biscayne Bay (exe!uding ctenophores I. Average produc tion/biomass ratios were 0.31 for Sagilta and 0.12 for Mnemiopsis.
