Resumo: | Colonization of artificial substrate by golden mussel, Limnoperna fortunei (Dunker, 1857), in the Jacuí River Delta, Rio Grande do Sul State, Brazil. In order to test a colonization method for Limnoperna fortunei, experiments were carried out in the Jacuí River Delta (Rio Grande do Sul State), using wood substrate (X form). The sampling localities are in the Jacuí River Delta: Jacuí Canal (CJ) and Port Docks (PO). In December (2005), three replicas of substrate were exposed at different depth levels (1; 1.5 and 2m) in each sampling locality (total of 18 replicas). In March, all substrates were collected from the water and transported to the laboratory. The substrates were dehumidified in a Pasteur oven (60°C). The individual adults (> 0.5mm) incrusted on different sides of the substrate (upperside, underside, lateral sides 1 and 2) were removed and quantified under a stereoscopic microscope. The average densities (ind.m-2) and standard errors of golden mussel adults were: CJ, 309.19 ± 30.70 and PO, 39.40 ± 6.00. The Kruskal-Wallis test (? = 0.05) did not present any significant differences between the depth levels (p = 0.715) or substrate sides (p = 0.617). However, the U Test presented differences (p < 0.0001) between sampling localities. The average densities of adult individuals verified in this study were situated between extreme values recorded earlier for wood substrate colonization, i. e. they were higher than those obtained for the Paraguay River and lower than those obtained for the Paraná River. |

Em dezembro de 2005 foram expostas (por três meses) três réplicas do substrato, em diferentes profundidades (1, 1,5 e 2m), em duas estações de coleta (total de 18 réplicas), no delta do rio Jacuí, no município de Porto Alegre: no Canal do Jacuí (CJ) e na doca do Cais do Porto (PO). Os substratos foram secos em forno de Pasteur (60°C). Os indivíduos adultos (> 0,5mm) incrustados nas diferentes posições no substrato (superior, inferior, lateral 1 e 2) foram removidos e quantificados sob o estereomicroscópio. A densidade média (ind.m-2) e o erro padrão nas estações de coleta foram: CJ, 309,19 ± 30,7 e PO, 39,4 ± 6,0. O teste de Kruskal-Wallis (? = 0,05) não demonstrou diferenças significativas entre profundidades (p = 0,715) e posições do substrato (p = 0,617), mas o Teste U demonstrou diferenças (p < 0,0001) entre estações de coleta. As densidades médias de adultos verificadas neste estudo foram superiores aos valores encontrados para o mesmo substrato, no rio Paraguai, e inferiores aos valores verificados no rio Paraná.Universidade Federal de Santa Catarina2009-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p7510.5007/2175-7925.2009v22n1p75Biotemas; v. 22 n. 1 (2009); 75-802175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p75/18721Copyright (c) 2011 Maria Cristina Dreher Mansur, Daniel Pereira, Cíntia Pinheiro dos Santos, Paulo Eduardo Aydos Bergonci, Bruno Mitidiero Thormann, Alice Michiyo Takedainfo:eu-repo/semantics/openAccessDreher Mansur, Maria CristinaPereira, Danieldos Santos, Cíntia PinheiroAydos Bergonci, Paulo EduardoThormann, Bruno MitidieroTakeda, Alice Michiyo2018-03-07T17:28:56Zoai:periodicos.ufsc.br:article/20519Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T17:28:56Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |

Colonization of artificial substrate by golden mussel, Limnoperna fortunei (Dunker, 1857), in the Jacuí River Delta, Rio Grande do Sul State, Brazil. In order to test a colonization method for Limnoperna fortunei, experiments were carried out in the Jacuí River Delta (Rio Grande do Sul State), using wood substrate (X form). The sampling localities are in the Jacuí River Delta: Jacuí Canal (CJ) and Port Docks (PO). In December (2005), three replicas of substrate were exposed at different depth levels (1; 1.5 and 2m) in each sampling locality (total of 18 replicas). In March, all substrates were collected from the water and transported to the laboratory. The substrates were dehumidified in a Pasteur oven (60°C). The individual adults (> 0.5mm) incrusted on different sides of the substrate (upperside, underside, lateral sides 1 and 2) were removed and quantified under a stereoscopic microscope. The average densities (ind.m-2) and standard errors of golden mussel adults were: CJ, 309.19 ± 30.70 and PO, 39.40 ± 6.00. The Kruskal-Wallis test (? = 0.05) did not present any significant differences between the depth levels (p = 0.715) or substrate sides (p = 0.617). However, the U Test presented differences (p < 0.0001) between sampling localities. The average densities of adult individuals verified in this study were situated between extreme values recorded earlier for wood substrate colonization, i. e. they were higher than those obtained for the Paraguay River and lower than those obtained for the Paraná River. |
