1974～1983年在菲律宾中部卢佐恩州大学淡水养殖中心进行的15种稻鱼养殖试验所获得的数据,采用多元线性回归方法进行分析,以阐明各种因素对鱼产量变化的影响.论述了各种管理策略对尼罗罗非鱼(Oreochromis niloticus)与几种洼地灌溉水稻Oryza sativa(L.)共生的产量之影响.气候资料从最近的气象站获取.通过回归分析,获得了鱼总产量(kg/ha)、鱼净产量(kg/ha)、鱼回捕率(%)、鱼生长率(g/d)和稻产量(kg/ha)有效养殖模式(P<0.001).鱼总产量66%的变化用7种自变量来加以阐明,即养殖期限、鱼放养重量和密度,氮、磷施用率,杀虫剂的施用和气温.
Data obtained from 15 rice-fish farms conducted at the Freshwater Aquaculture Center of the University of Luzhnán in the Central Region of the Philippines from 1974 to 1983 were analyzed using multivariate linear regression to elucidate the effects of various factors on changes in fish production. Effects of management strategies on the symbiotic yield of Oreochromis niloticus and several lowland irrigated rice Oryza sativa L. The climatological data were obtained from the nearest weather stations and the total fish production (kg / ha), net fish yield (kg / ha), fish capture rate (%), fish growth rate (g / d) and rice yield (kg / ha) The% change is illustrated by seven independent variables, namely, the duration of the cultivation, the stocking weight and density of the fish, the rates of application of nitrogen and phosphorus, the application of pesticides and the temperature.
