“…The smallest animal tracked (62 mm CL) weighed $220 g; therefore the transmitter was $1.3% of its body weight. This is well within the generally accepted value of 2% body weight that has been established for fish tracking studies (Baras and Lagardere 1995;Jepsen et al 2002). We observed no apparent difference in the movements of lobsters tagged using this method in comparison to other lobsters in the vicinity that were not tagged.…”

“…This efficiency was due to the fast immobility and recovery provided, and apparently, the clove oil did no show toxic effects on tagged fish (Taylor & Roberts, 1999). According to Jepsen et al (2002), the induction and recovery time is temperature dependent, and in general, pikes (Esox lucius) needed several hours to fully recover from anesthesia in cooler temperatures (water temperature < 2 o C). On the other hand, perch (Perca fluviatilis) was rapidly anesthetized on warm days (> 20 o C).…”

“…The induction time for anesthesia in this study could be considered normal. Average time to induction is approximately 2-4 min and the time for recovery is 4-6 min (Jepsen et al, 2002). Near the end of the surgery, the mix of clove oil and water that irrigates the gills was diluted (more water and less anesthetic), which enabled the fish to recover faster.…”

“…2). The surgical procedures followed Jepsen et al, 2002. Electrical immobilization was carried out in a larger container with the fish in a cloth sling. Electric current (AC) was applied through sheet metal plate electrodes at either end of the bath, and the amperage was slowly increased until the fish became immobilized and unresponsive to touch.…”

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.

“…The transmitters (48 3 18 mm, 220-mm antenna) weighed 19 g (in air), which represented 0.7-2.4% of the body weight of the 0.8-2.6-kg trout (mean 1.74 kg), a percentage considered to have no effect on fish swimming performance, condition, or growth (Brown et al 1999;Jepsen et al 2002;Brown et al 2006). It is possible that the trout exhibited unnatural behavior for a short period after tagging (e.g., Walker et al 2000), but this would presumably only affect results from the first tracking occasion, which occurred 12 d after the last fish was tagged.…”

Movement and Mortality of Adult Brown Trout in the Motupiko River, New Zealand: Effects of Water Temperature, Flow, and Flooding

et al. 2010

Abstract.-Management of the effects of water quality and flow on fisheries requires an understanding of the factors that control fish movements. We used radiotelemetry to monitor the movements of adult brown trout Salmo trutta in a New Zealand river over 11 months (September 2004 to August 2006 and linked those movements to the changes in flow and water temperature. Individual fish moved up to 41 km during the study. However, most fish moved less than 1 km. All of the trout that showed little movement throughout the summer were living in relatively deep pools that presumably provided cover. The rates of movement declined steadily over the spring-summer period, as flow decreased and water temperature increased. The percentage of fish moving was positively related to the average daily flow during the interval between tracking occasions and negatively related to the average daily water temperature, less than 20% of the tagged fish moving once temperatures were above 198C. A severe, 50-year flood occurred in March 2005 and was associated with the mortality of 60-70% of the remaining tagged fish, confirming that flood-induced mortality can affect a substantial proportion of an adult brown trout population.Research on river-resident salmonids over the last 15 years has indicated that widespread movement is much more common than previously thought (Gowan et al.
