“…The teleost fish were anesthetized with clove oil, based on the method described by Henyey et al (2002). The mitotic chromosomes were obtained from the cells of the anterior portion of the kidney (Bertollo et al, 1978;Foresti et al, 1993) and classified as metacentric (m) and submetacentric (sm), based on the arm ratio (Levan et al, 1964).…”

Three populations of the group Hoplias malabaricus from the hydrographic basins of the São Francisco, Araguaia/Tocantins and Xingu Rivers in Brazil were analyzed using classic cytogenetic methods (Giemsa staining, C-banding and Ag-NORs) and molecular methods (fluorescent in situ hybridization with 18S rDNA, 5S rDNA and 5SHindIII satellite DNA probes). The chromosome markers allowed the characterization of these populations as belonging to karyomorph A and the detection of inter-population divergences. These differences likely stem from different evolutionary histories resulting from geographic isolation between populations associated to the dispersive mode of these organisms, reinforcing genetic diversity in the group Hoplias malabaricus.Três populações do grupo Hoplias malabaricus das bacias hidrográficas dos rios São Francisco, Araguaia/Tocantins e Xingu foram analisadas citogeneticamente utilizando-se métodos clássicos (coloração com Giemsa, bandamento-C e Ag-RONs) e moleculares (hibridização in situ fluorescente com sondas de rDNA 18S, rDNA 5S e DNA satélite 5SHindIII). Os marcadores cromossômicos foram fundamentais para a caracterização destas populações como pertencentes ao cariomorfo A e para detecção de claras divergências interpopulacionais. Estas diferenças são provavelmente oriundas de diferentes histórias evolutivas do isolamento geográfico entre as populações associado ao modo dispersivo destes organismos, reiterando a diversidade genética do grupo Hoplias malabaricus.

“…Transmitters were implanted both surgically and esophagically. For the surgical procedures fish were anesthetized with clove oil or immobilized through electronarcosis, according to protocols described by Henyey et al (2002). We used these procedures to select the most appropriate method to be applied for the different species captured in the Itaipu lateral channel.…”

A preliminary study on the application of radio-telemetry techniques to describe the movements of fish in a bypass channel at Itaipu Dam (Paraná River), known as "Canal da Piracema," was carried out between January and February of 2004. Fourteen individuals of six species (Prochilodus lineatus, Leporinus friderici, Schizodon borellii, Pseudoplatystoma fasciatum, Pterodoras granulosus and Cichla kelberi) were intragastrically and surgically radiotagged and monitored by three experimental fixed radio-telemetry stations installed in the upper portion of the Canal. The surgical implantation of transmitters and the anesthesia using clove oil proved to be more efficient and allowed easier handling in comparison to intragastric implantation and electronarcosis immobilization. The use of fixed stations to obtain data was found to be very suitable for tracking movements of several different fish species in the Itaipu lateral channel. Three species (P. granulosus, S. borellii and C. kelberi) moved downstream after release. Two individuals of P. fasciatum and two of P. lineatus migrated upstream, leaving the channel 7 and 10 days and 2 and 24 days after release, respectively. Leporinus friderici was the only species that did not leave the release site until the end of the study period.Um estudo preliminar sobre a aplicação de técnicas de radiotelemetria para descrever os movimentos de peixes no canal de transposição da UHE Itaipu (Rio Paraná), conhecido como "Canal da Piracema", foi realizado entre janeiro e fevereiro de 2004. Seis espécies (Prochilodus lineatus, Leporinus friderici, Schizodon borellii, Pseudoplatystoma fasciatum, Pterodoras granulosus e Cichla kelberi) totalizando 14 indivíduos foram marcadas com radiotransmissores via cirúrgica e esofágica e rastreados através de três estações fixas experimentais de radiotelemetria instaladas na porção superior do Canal. A implantação de transmissores através de cirurgia e a anestesia por óleo de cravo mostraram-se mais eficientes e de fácil manejo do que a imobilização por eletronarcose e a implantação intragástrica. A utilização de estações fixas para obtenção dos dados mostrouse apropriada para rastrear os movimentos de diferentes espécies no canal de transposição de Itaipu. Três espécies (P. granulosus, S. borellii e C. kelberi) movimentaram-se para jusante após a soltura. Dois indivíduos de P. fasciatum e dois de P. lineatus migraram para montante, deixando o canal 7 e 10 dias e 2 e 24 dias após a soltura, respectivamente. Leporinus friderici foi a única espécie que não deixou o local de soltura até o final do estudo.

“…After a 24-h treatment period, the animals were anesthetized using clove oil, sacrificed as described by Henyey et al (2002), and fragments of the anterior kidney were removed. The acquisition of mitotic chromosomes was performed as described by Gold et al (1990).…”
