C.  aFeeding patterns in a fish community of Baia da Onca, a floodplain lake of the Aquidauana River, Pantanal, Brazil.  c1996  aThe stomach contents of 24 species of fish and unidentified species from four genera in a floodplain lake of the Pantanal were studied. Fish were collected during the dry season when the lake was isolated from the main river. A community food ingestion index (feeding index weighted by consumer biomass, FIWCB, where 0 &lt FIWCB &lt 1)was calculated to quantify feeding patterns. Detritus and algae ingested by Curimatidae were responsible for 46,5% of the FIWCB, while that for algae ingested by Loricariidae (armoured catfish) accounted for 13,2%. The importance of detritus in fish diets is discussed as a strategy for shortening food chains, thereby increasing community efficiency, and as a consequence, fish biomass. It was learnt that the main route of energy flow inthis perennial lake was through the detritus chain. The floodplain lakes function as a dry season feeding ground for small-sized species of fish, which are potential prey for the more highly valued larger species of fish.  aBrazil  afood chain  aPantanal  aCadeia Alimentar  aPeixe  aAlimentacao de comunidade  aConteudo estomacal  aFeeding index  aFish community feeding  aIndice alimentar  aStomach contents1 aPETRERE JUNIOR, M.  tFisheries Management and Ecologygv.3, p.229-237, 1996.
