Synopsis (short abstract) The use of organic manure in aquaculture is one of the main inputs in the Chinese system of integrated fish farming. Although many scientists in China and elsewhere have done much work on the effects of animal manure on aquaculture production (Chen Qiyu et al, 1982, Buck, 1978. 1979; Schroeder 1978, 1980; McGeacin et al, 1982; Stickney, 1977; Jhingran et al, 1980; Edwards, 1980; Zweig, 1981), little is known of the series of physical, chemical and biological processes which are taking place in a pond after application of manure. The complexity of energy recycling needs further studies. The aim of this study is to determine the independent contribution of three animal manures to changes in the ecological condition of pond water and fish production. The results to be obtained may provide the scientific basis for further research on the use of organic manure in fish culture.

Different animal manures were used in the experiment. Fish yield of the chicken-manured pond was the highest, followed by that of the duck-manured pond, the pig-manured pond and the cow-manured pond. The factors which affected the fish yield were the inorganic nitrogen, phosphorus, and the biomass of zooplankton and phytoplankton.

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.
