A review of shark satellite tagging studies

چکیده

a r t i c l e i n f o Recent advances in satellite tagging technologies have provided scientists growing opportunities to resolve previously unknown spatial ecology of marine predators, including sharks. Such an understanding is particularly important at this time given recent declines in shark populations worldwide. Here we reviewed 48 studies published in the primary literature between 1984 and 2010, addressing the most basic questions regarding the use of satellite tagging for studying shark behavior and ecology. For each study, the following aspects were analyzed: tagging location; species tagged; study focus; technology employed; sample size; tag attachment and deployment technique; duration of tracking; tag failure rate; and study limitation. The potential impacts of tagging on shark behavior and physiology are considered. Finally, we discuss how satellite tagging has furthered our current knowledge of shark behavior and consider the possibility of new tag developments that can improve our ability to resolve the mechanisms underlying shark habitat use.

Physiological stress response, reflex impairment, and survival of five sympatric shark species following experimental capture and release

In many fisheries, some component of the catch is usually released. Quantifying the effects of capture and release on fish survival is critical for determining which practices are sustainable, particularly for threatened species. Using a standardized fishing technique, we studied sublethal (blood physiology and reflex impairment assessment) and lethal (post-release mortality with satellite tags...

Vulnerability of the Oceanic Whitetip Shark to Pelagic Longline Fisheries

A combination of fisheries dependent and independent data was used to assess the vulnerability of the oceanic whitetip shark to pelagic longline fisheries. The Brazilian tuna longline fleet, operating in the equatorial and southwestern Atlantic, is used as a case study. Fisheries dependent data include information from logbooks (from 1999 to 2011) and on-board observers (2004 to 2010), totaling...

Satellite tagging and cardiac physiology reveal niche expansion in salmon sharks.

Shark populations are declining globally, yet the movements and habitats of most species are unknown. We used a satellite tag attached to the dorsal fin to track salmon sharks (Lamna ditropis) for up to 3.2 years. Here we show that salmon sharks have a subarctic-to-subtropical niche, ranging from 2 degrees to 24 degrees C, and they spend winter periods in waters as cold as 2 degrees to 8 degree...

Movement and environmental preferences of Greenland sharks (Somniosus microcephalus) electronically tagged in the St. Lawrence Estuary, Canada

Three Greenland sharks (Somniosus microcephalus) were tagged with electronic tags, in Baie St. Pancrace, St. Lawrence Estuary, Quebec, Canada. One shark was tagged on 23 July 2004, with an acoustic telemetry tag. Two sharks were each tagged with a popup satellite archival tag (PSAT) on 27 August 2004. Two of the sharks remained in or close to the bay, one for 47 days and the other for at least ...

Genetic diversity and connectivity of the megamouth shark (Megachasma pelagios)

The megamouth shark (Megachasma pelagios) was described as a new species in 1983. Since then, only ca. 100 individuals have been observed or caught. Its horizontal migration, dispersal, and connectivity patterns are still unknown due to its rarity. Two genetic markers were used in this study to reveal its genetic diversity and connectivity pattern. This approach provides a proxy to indirectly m...
