PIT telemetry as a method to study the habitat requirements of fish populations: application to native and stocked trout movements

Passive integrated transponder (PIT) technology was used to study the behaviour of fishes during the summer season in two headwater streams of northeastern Portugal. A total of 71 PIT tags (12 mm long x 2.1 mm diameter) were surgically implanted in 1+ stocked (39) and native (32) brown trout of two size classes (< 20.0 and ≥ 20.0 cm). Eight independent antennae, connected to a multi-point decoder (MPD reader) unit, were placed in different microhabitats, selected randomly every three days during the observation period (29 August to 9 September in Baceiro stream and 19 September to 4 October in Sabor stream). The results confirmed this method as a suitable labour efficient tool to assess the movement and habitat use of sympatric stocked and native trout populations. About 76.9% of stocked and 59.4% of native PIT tagged trouts were detected. Multivariate techniques (CCA, DFA and classification tree) showed a separation in habitat use between the two sympatric populations. Stocked trout mainly used the microhabitats located in the middle of the channel with higher depths and without cover. Furthermore, these fishes displayed a greater mobility and a diel activity pattern different to native trout populations

Análise do impacto da implantação de sistemas ERP nas características organizacionais das empresas de construção civil

Uma das causas do insucesso do ERP nas empresas de construção civil é o fato da implantação desse sistema ser uma grande mudança organizacional. O objetivo desta pesquisa é identificar como a implementação do sistema ERP impacta na organização e nos processos gerencias das empresas de construção civil. Foi realizada uma survey em uma amostra de empresas construtoras brasileiras. Os dados foram coletados por meio de um questionário encaminhado por email a dois grupos de empresas: com e sem ERP implantado. A partir da análise estatística discriminante foi possível identificar as variáveis relacionadas ao nível de desenvolvimento dos processos de gestão e as características organizacionais que mais distinguem os dois grupos de empresas. Os resultados revelaram que a implantação do ERP impacta nas variáveis da maturidade organizacional nos seguintes aspectos: visão estratégica, relacionamento com cliente, gerenciamento de recursos humanos, gestão financeira e de TI

Session C7: Passage Efficiency and Behavior of Adult Sea Lamprey in a Vertical-Slot Fishway

Abstract: Dams and weirs are known to have major impacts on migratory fish such as the sea lamprey Petromyzon marinus L., but these deleterious effects can be mitigated by the construction of efficient fishways. The Açude-Ponte dam at Coimbra represented the upstream limit of sea lamprey’s distribution in River Mondego until 2011, when a vertical-slot fishway was installed. Since then, several methodologies including visual counts and bio-telemetry techniques were used to monitor its efficiency. In 2014, a total of 221 adult lampreys were tagged with PIT tags to assess the efficiency of the fishway. During the 2015 spawning season, additional 200 lampreys will be tagged to assess the interannual variability of the fishway efficiency. From 28 lampreys tagged with conventional radio transmitters and released downstream of the weir, eight (ca. 30%) successfully negociated the fishway, reaching the upstream spawning areas in the main river stretch and tributaries. Data obtained from three lampreys tagged with EMG transmitters give a first glance of the fine-scale behavior and muscular effort required during fishway negotiation. Finally, visual counts identified the upstream passage of nearly 8,000 lampreys during the 2013 and 22,000 during 2014 spawning seasons. A statistical model developed with this data clearly shows that the weir discharges significantly influence the migratory behavior in the vicinity of the fishway, limiting its efficiency during high discharge periods
