光合细菌在越冬池中的应用研究

APPLY STUDU ON PHOTOSYNTHETIC BACTERIA IN OVERWINTERING POND

在黑龙江水产研究所民富鱼类培育中心进行了越冬池冰下施光合细菌对鱼类越冬影响的试验。经过水质定期分析及越冬成活率的比较 ,得出越冬池施光合细菌能使越冬池冰下水体中溶解氧和浮游植物生物量的波动较小 ,净化越冬池水质 ,使越冬水体各理化因子处于较稳定的状态 。

By applying photosynthetic bacteria under the ice of overwintering pond,the experiment about the effect on fishes in winter was carried out in Minfu fishery base of Heilongjiang viver Research Institate.By analyzing water quality regulary and commparing the overwintenig Survival rate,the resules showsthat The fluctuattion of dissowed oxygen and the biomass of plandto under the ice of overwintering jpond in witer by applying photosynthetic bacteria is very little,and water quality is also cleaned,physical and chemical factos in overwinterig waters remain steble,which make fishes live through the winter safely.
