摘要: 通过对四川地区养殖池塘生石灰清塘后主要理化指标水温、pH值、溶解氧、COD、营养盐等的监测,探讨主要理化因子的变化特点。通过高pH值对岩原鲤鱼种的急性毒性试验,计算出岩原鲤鱼种对pH值的安全值为8.565。研究结果表明,把pH值作为生石灰清塘后确定鱼种下塘时间的主要指标是可行和适宜的。根据四川地区目前的清塘方式,鱼种的适宜下塘时间为清塘后第5 d。

Abstract: By comprehensively detecting the main physical and chemical factors of breeding ponds in Sichuan province area, which includes water temperature(T), pH value, dissolved oxygen(DO), chemical oxygen demand(COD), nutritive salts, and so on, after using the quicklime method, the variations of corresponding key physical and chemical factors are investigated in this paper. Also, with the aid of acute toxicity experiment aiming for Procypris rabaudip, the accurate safe pH value 8.565 is obtained. Above results indicated that, it is feasible to take the pH value as a key index of the exact time delay for stocking the species after clearing ponds. Our study demonstrated that, five-day delay is enough and suitable to stock the species after clearing ponds in Sichuan province area.
