关于碱性水域水化因子与渔业利用问题的探讨

An Approach to the Problem of Water chemical Factors and Fishery Utilization in Alkaline Waters

根据1986～1992年对三勇水库、敖包泡等几个碱性水域的渔业状况及水化学观测的结果,总结了养鱼水域碱度的高限指标。提出碱度16 mmol·L^(-1)(pH9.24)是可进行鲤、草、鲢精养的碱度上限。碱度在18 mmol·L^(-1)(pH9.42)以上的水域要选择耐碱鱼类养殖。鲢鳙在此水域中不能存活。

The fishery conditions and hydro-chemistry of alkaline waters such as Sany-ong Reservoir, Ao Bao pools and others were investigated from 1986 to 1992, and the maximum alkalinity was proposed for fish culture, that is a alkalinity of 16 mmol·L-1 (pH9. 24) for the intensive culture of common carp (Cyprinus carpio L. ), grass carp (Ctenopharyngodon idella) and siliver carp (Hypophthalmichthys molitrix). Alkaline resistive fish should be selected for culture where alkalinity reaches 18 mmol·-1 in waters as silver carp and bighead carp (Aristichthys nobilis) can not tolerate the alkalinity.
