中文摘要:
      本文研究池塘养殖的花鲢在各发育、生长时期摄食浮游植物、浮游动物的规律。花鲢终生所摄食的浮游植物种类是基本相同的,摄食的浮游动物种类在不同发育生长期有所不同。养鱼池中浮游植物与浮游动物的数量.对花鲢摄食强度的影响有同样重要的作用。但是,浮游动物的热能高,在质量上显得比浮游植物重要。所谓“不能消化”的浮游植物种类,起着维持养鱼池生态平衡作用。影响花鲢产量的因素是水体中能提供营养的悬浮有机体和有机物的数量。
英文摘要:
      The prey-predator relationship between the plankton and the pond-cultured bigheed at every growing stage has been studied in this paper. The fishconsumes the same species of phytoplankton, but it takes different species of zooplank-ton at its every growing stage. The abundance of phytoplankton as well as zooplank-ton in the pond are of the same importance in the feeding intensity of the fish.Since the zooplankton has higher calorie than that of phytoplankton, it becomes moreimportant in terms of quality. It is considered that the factor which influences theproduction of the bighead is the abundance of suspended nutritive matters in the water.So it is not nessary to divide the phytoplankton into "digestible or "undigestible".
