A barrier to upstream migration in the fish passage of Itaipu Dam (Canal da Piracema), Paraná River basin Neotropical Ichthyology
Fontes Júnior,Hélio Martins; Castro-Santos,Theodore; Makrakis,Sergio; Gomes,Luiz Carlos; Latini,João Dirço.
The majority of the fish passages built in the Neotropical region are characterised by low efficiency and high selectivity; in many cases, the benefits to fish populations are uncertain. Studies conducted in the Canal da Piracema at Itaipu dam on the Parana River indicate that the system component designated as the Discharge channel in the Bela Vista River (herein named Canal de deságue no rio Bela Vista or CABV), a 200 m long technical section, was the main barrier to the upstream migration. The aim of this study was to evaluate the degree of restriction imposed by the CABV on upstream movements of Prochilodus lineatus and Leporinus elongatus, Characiformes. Fish were tagged with passive integrated transponders (PIT tags) and released both downstream and...

Activity patterns, home-range size, and habitat utilization of Sarpa salpa (Teleostei : Sparidae) in the Mediterranean Sea ArchiMer
Jadot, Catherine; Donnay, A; Acolas, M; Cornet, Y; Begout, Marie-laure.
Acoustic telemetry was used to record diel movement and habitat utilization of the salema (Sarpa salpa) (Teleostei: Sparidae) during three consecutive summers from 2000 to 2002 in the Calvi and Achiarina bays of Corsica in the Mediterranean Sea. A total of 18 fish was equipped with acoustic transmitters inserted in the body cavity, 13 were tracked in the Bay of Calvi (275 mm +/- 26.9 L-F), and 5 in Achiarina Bay (260 mm +/- 33.6 LF). Two different systems were used to track the fish. The one used in the Bay of Calvi was a manual receiver and a directional hydrophone. The second system, used in Achiarina Bay, was a radioacoustic-positioning (RAP) system that continuously monitored the movements of the fish. Fish positions were put in a geographic...

Comparison of two tagging techniques for Sarpa salpa: external attachment and intraperitoneal. implantation ArchiMer
Jadot, C.
For a given species in a particular environment, the success and the harmlessness of transmitter attachment appear to be highly specific. As no information was available for the tagging of the strepie, Sarpa salpa, a suitability study of attachment techniques was needed. Two types of transmitter attachments were investigated: (1) externally, placed on the back of the fish below the dorsal fin by means of two threads sutured through the dorsal musculature, and (2) internally, in the peritoneal cavity. Twenty-five fish were monitored over a 14-d period for survival, surgical healing, injury occurrence and post-tagging behaviour. Even though we observed a 100% survival rate for both groups, with no noticeable buoyancy or swimming alteration, findings from...

Conservation physiology of marine fishes: state of the art and prospects for policy ArchiMer
Mckenzie, David; Axelsson, Michael; Chabot, Denis; Claireaux, Guy; Cooke, Steven J.; Corner, Richard A.; De Boeck, Gudrun; Domenici, Paolo; Guerreiro, Pedro M.; Hamer, Bojan; Jorgensen, Christian; Killen, Shaun S.; Lefevre, Sjannie; Marras, Stefano; Michaelidis, Basile; Nilsson, Goran E.; Peck, Myron A.; Perez-ruzafa, Angel; Rijnsdorp, Adriaan D.; Shiels, Holly A.; Steffensen, John F.; Svendsen, Jon C.; Svendsen, Morten B. S.; Teal, Lorna R.; Van Der Meer, Jaap; Wang, Tobias; Wilson, Jonathan M.; Wilson, Rod W.; Metcalfe, Julian D..
The state of the art of research on the environmental physiology of marine fishes is reviewed from the perspective of how it can contribute to conservation of biodiversity and fishery resources. A major constraint to application of physiological knowledge for conservation of marine fishes is the limited knowledge base; international collaboration is needed to study the environmental physiology of a wider range of species. Multifactorial field and laboratory studies on biomarkers hold promise to relate ecophysiology directly to habitat quality and population status. The 'Fry paradigm' could have broad applications for conservation physiology research if it provides a universal mechanism to link physiological function with ecological performance and...

Effect of anesthetic, tag size, and surgeon experience on postsurgical recovering after implantation of electronic tags in a neotropical fish: Prochilodus lineatus (Valenciennes, 1837) (Characiformes: Prochilodontidae) Neotropical Ichthyology
Lopes,João M.; Alves,Carlos B. M.; Silva,Fernanda O.; Bedore,Alessandra G.; Pompeu,Paulo S..
ABSTRACT Implantation of telemetry transmitters in fish can be affected by different parameters. This study aimed to evaluate the effect of type of anesthetic, tag size, and surgeon experience on surgical and postsurgical wound healing in the neotropical fish Prochilodus lineatus . In total, eighty fish were surgically implanted with telemetry transmitters and forty fish were kept as controls. Forty fish were implanted with a small tag and other forty were implanted with a large tag. Similarly, forty fish were anesthetized with eugenol and forty fish were anesthetized by electroanesthesia, and forty surgeries were performed by an expert surgeon and forty surgeries were performed by novice surgeons. At the end of the experimental period seventeen (21.3%)...

Panthers and Forests in South Florida: an Ecological Perspective Ecology and Society
Comiskey, E. Jane; University of Tennessee; ecomiske@tiem.utk.edu; Bass, Jr., Oron L; Everglades National Park; Sonny_Bass@nps.gov; Gross, Louis J; University of Tennessee; gross@tiem.utk.edu; McBride, Roy T; Livestock Protection Company;; Salinas, Rene; University of Tennessee; salinas@tiem.utk.edu.
The endangered Florida panther (Puma concolor coryi) survives in an area of pronounced habitat diversity in southern Florida, occupying extensive home ranges that encompass a mosaic of habitats. Twenty-one years of daytime monitoring via radiotelemetry have provided substantial but incomplete information about panther ecology, mainly because this method fails to capture movement and habitat use between dusk and dawn, when panthers are most active. Broad characterizations of panther habitat suitability have nonetheless been derived from telemetry-based habitat selection studies, focusing narrowly on forests where daytime resting sites are often located. The resulting forest-centered view of panthers attributed their restricted distribution and absence of...

Preventing injuries caused by radiotelemetry collars in reintroduced red-rumped agoutis, Dasyprocta leporina (Rodentia: Dasyproctidae), in Atlantic Forest, southeastern Brazil Rev. Bras. Zool.
Cid,Bruno; Costa,Rodrigo de C. da; Balthazar,Daniel de A.; Augusto,Anderson M.; Pires,Alexandra S.; Fernandez,Fernando A. S..
Reintroduction has been recognized as a powerful conservation tool, but in order to ensure its success, animal monitoring is highly recommended. One way to monitor released animals is to put radiotelemetry collars on them. These devices, however, can harm the subjects, causing serious wounds. Our objectives in this work were to describe the injuries caused by a radiotelemetry collar model on reintroduced agoutis and to propose modifications to it. We equipped agoutis with TXE-311C radio collars (Telenax Wildlife Telemetry) before releasing them in the wild. They acquired serious wounds and one animal died. We then modified the collar structure to reduce its width and retention of water. After these modifications, the injuries did not occur again. As...

Tagging juvenile seabass and sole with telemetry transmitters: medium-term effects on growth ArchiMer
Begout, Marie-laure; Coves, Denis; Dutto, Gilbert; Laffargue, Pascal; Lagardere, Francoise.
The effects of tagging with acoustic transmitters on the growth of juvenile seabass, Dicentrarchus labrax (L.) (initial mean mass +/- SD, 173 g +/- 23.4) in a 47 d tank experiment, and sole. Solea solea (L.) ( 103.2 g +/- 14.8) in a 72 d tank experiment and (104.0 g +/- 18.4) in a 58 d salt marsh mesocosm experiment were examined. Twenty externally tagged seabass grew more slowly than the 20 with surgically implanted tags, which reached the same mass as nine control fish. Movements of the external transmitter's harness caused abrasions of the skin and loss of the tag in 60% of the cases. We thus recommend implanting transmitters for telemetry studies of juvenile seabass weighing between 120 and 214 g and carrying a tag that represents 2.2-2.5% of body...

Toward a Panther-centered View of the Forests of South Florida Ecology and Society
Kerkhoff, Andrew J; University of New Mexico; kerkhoff@unm.edu; Milne, Bruce T; University of New Mexico; bmilne@sevilleta.unm.edu; Maehr, David S; University of Kentucky; dmaehr@pop.uky.edu.
Anthropogenic habitat degradation and loss is the single largest threat to the endangered Florida panther, Puma concolor coryi. Conservation of the subspecies must be undertaken on the scale of the entire landscape. Thus, a view of the forested landscape of South Florida must be developed that is meaningful with reference to the panther. We approach this problem by analyzing the spatial interactions of panthers and forests at multiple scales. We apply tools derived from fractal geometry to the analysis of 12 years of telemetry observations of panthers and remotely sensed forest cover imagery. A fractal characterization extends conventional scale-dependent measures of forest density and relates intuitively to panther ecology. To move toward a...
