As a rule, the food of these species consists largely of phytoplankton common in the sea at the time of feeding, indicating the absence of selective feeding.

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...             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。 文摘来源          Labidocera euchaeta Gisbrecht is a more carnivorousely cmnivorous copepod. Its feeding rates on phytoplanfcton vary with different phytoplankton species. Feeding switching is found for L. euchaeta feeding on mixed foods of Artemia nauplii and Prorocentrum micons. The switching is ecologically important for the survival of L. euchaeta in the sea.             真刺唇角水蚤(Labidooera enchaeta Giesbrecht)的食性是以肉食性为主的杂食性。它对不同浮游植物种类的摄食率不同。在动物和植物混合食物(Artemia 无节幼虫和 Proroentrum micans)中,真刺唇角水蚤存在食性转变,这对它在自然海区中的生存具有重要的生态意义。 文摘来源   << 更多相关文摘         相关查询: 浮游植物种类更替 种类 浮游植物 土壤种类 病原种类 工艺种类 食品种类 微生物种类 细菌种类 杂草种类 中国种类 能源种类  对查询结果不满意
