The preliminary models contains boxes for fish of the two species, phytoplankton, zooplankton, planktonic microbes, benthic microbes, macrobenthos, meiobenthos, frogs, detritus, and is based on research ponds at the Domasi Experimental Farm, Malawi, and from the literature. Construction of this model demonstrated gaps in our knowledge on food web structure and on the productivity of the groups of organisms in grass-fed ponds. Nevertheless, the model was useful as it suggested research directions for improvement of pond productivity.</style></abstract><accession-num><style face="normal" font="default" size="100%">3869908</style></accession-num><notes><style face="normal" font="default" size="100%">Conference ICES Theme Session on Trophic Models in Aquatic Ecosystems, Copenhagen (Denmark), Oct 1990International Cent. for Living Aquatic Resources Management, Manila (Philippines)Trophic models in aquatic ecosystems., iclarm, manila (philippines), 1993ICLARM conference proceedings.
