摘要
在6个混凝土池中对长鳃异枝鱼(Heterobranchus longifilis)与加利平克拉尾鱼(Clarias gariepinus)杂交的浮游生物丰度和鱼种生长情况进行了为期14周的监测。这120条鱼种接受了三种处理。两个重复的池塘用家禽粪便和牛粪施肥，而第三个不施肥，作为对照。而鸡粪与牛粪的肥力差异显著(p 0.05)。3个处理的鱼种平均总长度(MTL)差异不显著，但鱼池平均增重(MWT)和特定生长率(SGR)差异显著(p > Animal Production Research Advances Vol. 2 (4) 2006: pp. 197-201)
The effect of cow dung and poultry droppings on plankton abundance and growth of Heterbranchus longifilis x Clarias gariepinus hybrid, reared in concrete ponds
Plankton abundance and growth of fingerlings of hybrid cross between Heterobranchus longifilis (male) and Clarias gariepinus (female) were monitored in six concrete ponds for fourteen weeks. The one hundred and twenty fingerlings were subjected to three treatments. Two replicated ponds were fertilized with poultry droppings and cow dung while the third had no fertilizer, which served as the control. While the fertilized ponds had significantly higher (p 0.05) between those of poultry droppings and cow dung. The mean total length (MTL) measurements of the fingerlings were not significantly different in the three treatments, but the mean weight gain (MWT) and specific growth rate (SGR) of the fertilized ponds were significantly (p > Animal Production Research Advances Vol. 2 (4) 2006: pp. 197-201
