桂西北山区红罗非鱼与禾花鲤稻田养殖生长对比

Comparative Growth of red tilapia (Oreochromis niloticus) and Procypris merus by Using Rice-Fish Culture System at Northwestern of Guangxi Province

摘要: 为探索新的适宜高寒山区的稻田养殖品种，在广西桂西北山区进行红罗非鱼与禾花鲤的养殖对比试验。试验结果表明，经过117天的养殖，红罗非鱼的生长快于当地的禾花鲤，平田养殖对比沟坑田养殖水稻稻谷产量差异不显著，红罗非鱼养殖模式的稻谷产量显著高于禾花鲤养殖模式。红罗非鱼养殖个体分化小，整体规格优于禾花鲤，适合稻田养殖的商品化。沟坑养殖模式下，稻田鱼的产量更高，产生的效益更多，养殖红罗非鱼的效益更大。

Abstract: The study was conducted to investigate new aquaculture varieties by using rice-fish culture system on cold and mountainous regions, a comparative experiment was made of feeding red tilapia (Oreochromis niloticus) and Procypris merus during a 117-day grow-out period at northwestern of Guangxi province. Results obtained can be summarized in the following: growth performance of red tilapia (Oreochromis niloticus) was better than that of Procypris merus, grain yield was no significant differences between trench and pond model paddy and normal paddy, grain yield of feeding red tilapia (Oreochromis niloticus) group was significantly higher than feeding Procypris merus group. The results indicated that red tilapia (Oreochromis niloticus) was suitable for Commercialization on rice-fish culture system. It was concluded that economical efficiency of feeding red tilapia (Oreochromis niloticus) in trench and pond model paddy was higher because of more production.
