No results found.Four types of green manure were used in the polyculture ponds with silver carp and bighead carp as the main species. Direct application of green manure resulted in a higher fish production ranging from 19.59 to 25.33 kg/ha/day. Sudan grass was best among four types of green manure. -

Establishment of a Network of Aquaculture Centres in Asia
1983Also available in:
No results found.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. -
