我国南美对虾的饲料系数
he Feed Coefficient of Growing Vannamei
饲料系数即是衡量水产养殖经济效益的主要指标之一。但国内鲜有这方面的生产型实验研究。本研究目的是尝试找出在国内养殖南美对虾所需的饲料系数，作为参考基准。但研究发现这平均饲料系数为2.13, 远远超出平均值1.2。这新数字恐怕不宜作为新基准,但却反映出某些养户的饲料成本高居不下。因此, 笔者有理由相信, 国内养户能维持饲料系数在1.2±5%范围内，属良好效益，而饲料用量低于这数属优秀。
Feed coefficient is one of the most important key indicators in evaluating the economic effect of growing Vannamei. Nevertheless, there is lack of empirical study in relation to this evaluation in China. The average feed coefficient is said to be 1.2 – 1.7. In this study, the figure, 2.13, found is, however, far higher than the claimed average. Despite the fact that the authors find it uncomfortable to use 2.13 as the benchmark, the findings have shown that some aqua-cultural farmers consume feed much higher than the average rate.
