中文摘要:
      报道了养鳗池塘的浮游生物种量及其与鳗摄食的关系,论述了水质良好的养鳗池塘浮游生物优势种、养鳗池和传统家鱼池生态学特点和养鳗池水质的有效调控措施。养鳗池塘的浮游生物群落结构与我国传统家鱼高产池塘的浮游生物群落结构区别较大。黑仔鳗塘的浮游植物的优势种类为绿藻类,生物量占浮游植物总量的80%以上;成鳗塘的浮游植物则以硅藻类和绿藻类占优势,生物量分别占浮游植物总量的40%和37%。浮游动物则以轮虫和桡足类为主,枝角类的比例很少。浮游生物的丰度和群落结构对鳗的摄食有很大的影响。 更多还原
英文摘要:
      I n this paper , the rela tionship between plankton in the eel ponds and eel feeding was described , and the dominant plankton species of “good water quali ty” sui table for eel-culture , the ecological characterist ics in the eel ponds and in the t radict ional cultur ed-fishes ponds were expounded .The me thod for cont rolling water quali ty in the eel ponds was also discussed .The resul t of the pr esent research indicated that plankton communit ies in the eel ponds was significantly differ ent from tha t in the tr adict ional cul turedfishes ponds .The dominant species of phytoplankton in the elve r ponds was Chloraphyta , its biomass accounted f or over 80 % of total phytoplankton biomass ;and the dominant species of phytoplankton in the grow-out eel ponds wer e Bacil lar iophyta and Chloraphyta , both of the above accounted for 40 % and 37 % of total phytoplankton biomass respectively .The dominant species of zooplankton in the eel ponds wer e Ro ti fer a and Copedode , the per centage of Cladocera was lower .The plankton' s abundance and str ucture af fected eel feeding significant ly .
