中文摘要:
      本文从养鱼池塘生态系统能量利用各环节,分析了两种不同养殖结构鱼塘的生态学能量利用效率。主养草食性鱼类池塘,其输入的总补助能、光合能、生物能的转换效率分别为9.86%、6.92%、10.10%;其生产吨鱼消耗的总补助能、光合能、生物能分别为46.64GJ、66.46GJ、45.54GJ。而对于主养滤食性鲢、鳙的池塘,其对应的指标分别为8.43%、3.75%、8.66%、46.99GJ、105.52GJ、45.73GJ。由于池塘生产结构的差异,滤食性鲢、鳙对太阳能的利用率在不同池塘中有差异,但由初级生产力到滤食性鱼类产量其净转换效率在不同养殖结构池塘中基本相同,主养草食性鱼类池塘为1.45%;主养滤食性鲢、鳙的池塘为1.43%。根据生态-经济综合指标EY值判断,主养草食性鱼类的池塘生产方式优于以滤食性鱼类为主的生产方式。

      This paper analyzes the energy ut ilization efficiency on every sectio n in dif ferent main cultivated f ish ponds .In the pond of main cultivated g rass carp , its transforming eff iciency of the to tal supplement energy 、photo-synthetic energy and creature energy were 9 .86 %, 6 .92 % and 10 .10 % respectively .Meanw hile , the consumed energy of culturing one to n fish yield was 46 .64GJ , 66 .46GJ and 45 .54GJ respect ively .In the pond of main cultivated silver carp and big head carp , the appropriate data were 8 .43 %, 3 .75 %, 8 .66 %, 46 .99GJ , 105 .52GJ , 45 .73GJ respectively .As the dif ference of main function in tw o ponds, there w as some diversity for utilizat ion the radiation by silver carp and big head carp .The net conversion ef ficiency w as almost equal, w hich was f rom the primary productivity to the crops of the filtered food f ish .The coeff icient w as 1 .45 % and 1 .43 % in main culturing grass carp fish pond and in main culturing silver carp and big head carp fish ponds .Based on the eco-economic index EY , the producing style of main cultivated grass carp was superior to that of main cult ivated silver carp and big head carp .
