| 摘 要： | 本文介绍了通过对鱼体、饵料、粪肥的δc值的分析来追踪碳元素的流向,从而研究施肥鱼池中鱼类生长能源的动力学过程的结果。研究表明,滤食性鱼类的生长能源主要来自自养生产系统;杂食性鱼类中的白鲫和鲤鱼,分别有三分之一以上和二分之一左右是来自自养生产系统,而其他部分的生长能源,则来自异养生产系统。

| Abstract: | In manured fish ponds, the conversion of manure-feeds-fish undergoes a complicated process of pond dynamics. In order to well understanding andmanipulation of this process so as to improve farming productivity, we introducedcarbon isotype analysis into the experiment. We accurately measured Delta C in organic matters such as fish body, fish feede and manure. The orientation of carbonwas traced by means of mass spectrometer and the interactions of fish growth andcomplicated food web texture in manured pond were analyzed and studied. The resultsshowed that the species of filtering and omnivorous food habits in manured pondobtain carbon from both autotrophic and heterotrophic resources. Obviously, it is ofpractical significance in organising aquanultural activities and making clear the ponddynamies. |
