• 中文摘要： 　　我們建立一個通用化的模式，以估算海洋浮游動物在海洋中被捕食率及成長率的動力學，常用的藍德吉的稀釋法是本模式的一個個例。而藍德吉的稀釋法所估算出來的捕食係數(g)實際上是捕食者之初濃度與真捕食常數的乘積。本模式亦顯示捕食者之初濃度及其成長轉換率之多寡捕食係數(g)估算準確度的影響極大。而使用本報告所建議的三種方法將可使此估算更精確。
• 英文摘要： We present a preliminary model for estimating zooplankton grazing kinetics that uses growth rate ofpredator and mortality rate of prey in the marine ecosystem. The Landry's dilution technique is a uniquefeature of this model. Results obtained from the model indicate that the mortality coefficient estimatedfrom the Landry's dilution technique is the multiplication of intrinsic grazing constant and initial concentra-tion of predator. Also demonstrated by those results, growth yield of predator (conversion efficiency) andinitial concentration ratio (supply availability) of predator and prey affect estimation of kinetic parameters.In addition, three methods are proposed to enhance the estimation accuracy of the kinetic parameters thatare free from the effects of supply availability and conversion efficiency.
