Resumo: | For each of the most representative taxonomic groups in the fresh-water zooplankton one or more species were cultured in the laboratory. The potential growth of the different species populations were compared by determining their intrinsic rate of natural inscrease under defined laboratory conditions. The highest value of intrinsic rate was found for the rotifer Brachionus falcatus, and the lowest value was for the calanoid copepod Argyrodiaptomus furcatus. Such values closely reflected the differences in the life-cycles of these organisms. The maximum yield both in density as well as biomass was obtained for Rotifera and Ciliophora. They reached densities of 300,000 ind./l and 1,000,000 ind./l respectively and corresponding biomass of 480 mg PS/l and 80 mg PS/l. For the microcrustaceans the yield was much smaller, around one order of magnitude lower for Cladocera and two for Copepoda. |

O potencial de crescimento das diferentes populações foi investigado determinando-se a taxa intrínseca de aumento natural para cada espécie cultivada. O maior valor da taxa intrínseca foi obtido para o rotífero Brachionus falcatus; valores intermediários para os cladóceros Daphnia similis, D. laevis, Ceriodaphnia silvestrii e Moina micrura e o mais baixo valor para o copépode Argyrodiaptomus furcatus. Estes valores refletiram as diferenças existentes entre os ciclos de vida destes organismos, isto é, os tempos de geração extremamente curtos de Ciliophora e Rotifera e os mais longos para os Copepoda. Os maiores rendimentos tanto em termos numéricos quanto em biomassa foram obtidos para Rotifera e Ciliophora. Estes alcançaram densidades de 300.000 indivíduos/l e 1.600.000 indivíduos/l respectivamente e biomassa de 480 mg P.S./l e 80 mg P.S./l.Universidade Federal de Santa Catarina1994-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2269210.5007/%xBiotemas; v. 7 n. 1/2 (1994); 94-1092175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/22692/20661Copyright (c) 1994 Odete Rocha, Lúcia Helena Sipaúba Tavaresinfo:eu-repo/semantics/openAccessRocha, OdeteTavares, Lúcia Helena Sipaúba2012-01-24T14:11:50Zoai:periodicos.ufsc.br:article/22692Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2012-01-24T14:11:50Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
