| dc.description | In a manured fish pond, the conversion of manure-feeds-fish undergoes a complicated process of pond dynamics. In order to understand and manipulate this process and to help us improve farming productivity, we introduced carbon isotope analysis in our experiment. We measured delta C of organic matter, such as fish body, fish feeds, manure, etc. And with this information, we traced the flow of carbon, analysing the interactions of fish growth and the complicated food web in a manured pond. The dat a show that filtering and omnivorous species in this manured pond obtained carbon from both autotrophic and heterotrophic production systems. This is of practical significance in planning aquacultural activities and seeking the truth of pond dynamics. | |
