Electronic tags that archive or transmit stored data to satellites have advanced the mapping of habitats used by highly migratory fish in pelagic ecosystems. Here we report on the electronic tagging of 772 Atlantic bluefin tuna in the western Atlantic Ocean in an effort to identify population structure. Reporting electronic tags provided accurate location data that show the extensive migrations of individual fish (n = 330). Geoposition data delineate two populations, one using spawning grounds… 


SUMMARY Pop-up satellite archival tags were attached to Atlantic bluefin tuna in the southern Gulf of St. Lawrence in September and October of 2007 and 2008 and datasets were obtained from 14 tags of

Results of satellite tagging of Atlantic bluefin tuna, Thunnus thynnus, off the coast of Ireland

Pop-up satellite archival tags were attached to six Atlantic bluefin tuna (Thunnus thynnus) off the west coast of Ireland in autumn 2003 and 2004. The satellite tags measured pressure, ambient


SUMMARY From 2002-2011, dispersal patterns of Atlantic bluefin tuna (ABFT) released from New England and Canadian foraging grounds (n=126 , estimated sizes 150-185 cm curved fork length, CFL) with

Tracking the fidelity of Atlantic bluefin tuna released in Canadian waters to the Gulf of Mexico spawning grounds

The objective of this study was to advance the use of pop-up satellite archival tags to track the migrations of Atlantic bluefin tuna (Thunnus thynnus) to their spawning grounds. Deployment of tags

Tracking bluefin tuna reproductive migration into the Mediterranean Sea with electronic pop‐up satellite archival tags using two tagging procedures

Analysis of the median depth indicated a shallow behavior during both day and nighttime throughout the return phase of the fish from the Mediterranean Sea to the Atlantic Ocean with the exception of the area around the Strait of Gibraltar, where they showed a deeper behavior that coincided with a marked vertical gradient in the currents.

Tracking Atlantic bluefin tuna from foraging grounds off the west coast of Ireland

Pop-up archival tags (n = 16) were deployed on Atlantic bluefin tuna (ABT) off the west coast of Ireland in October and November 2016 (199–246 cm curved fork length), yielding 2799 d of location

Electronic Tagging of Atlantic Bluefin Tuna (Thunnus thynnus, L.) Reveals Habitat Use and Behaviors in the Mediterranean Sea

We analyzed the movements of Atlantic tuna (Thunnus thynnus L.) in the Mediterranean Sea using data from 2 archival tags and 37 pop-up satellite archival tags (PAT). Bluefin tuna ranging in size from

First tagging data on large Atlantic bluefin tuna returning to Nordic waters suggest repeated behaviour and skipped spawning

Atlantic bluefin tuna (Thunnus thynnus; ABFT) is one of the most iconic fish species in the world. Recently, after being very rare for more than half a century, large bluefin tunas have returned to

Estimating Natural Mortality of Atlantic Bluefin Tuna Using Acoustic Telemetry

It is demonstrated that acoustic tags can provide vital fisheries independent estimates for life history parameters critical for improving stock assessment models and the rate of instantaneous annual natural mortality is estimated.

Movement of Atlantic bluefin tuna (Thunnus thynnus) as determined by satellite tagging experiments initiated off New England

Pop-up satellite archival tags attached to 35 Atlantic bluefin tuna (Thunnus thynnus) in 1998, 2000, and 2001 provided information on the horizontal and vertical movements and environmental preferences ofbluefin tuna.

Migratory Movements, Depth Preferences, and Thermal Biology of Atlantic Bluefin Tuna

The results obtained from tagging of Atlantic bluefin tuna with implantable archival and pop-up satellite archival tags provide insights into the seasonal movements and environmental preferences of this species.

Tracking fish with electronic tags

The distributions of many species of fish show pronounced seasonal changes as a result of migration. We are using long-term electronic tagging to study the migratory behaviour of fish in the North

Results of pop-up satellite tagging of spawning size class fish in the Gulf of Maine: do North Atlantic bluefin tuna spawn in the mid-Atlantic?

Twenty giant bluefin tuna were captured in September and October 1997 and tagged and released with pop-up satellite tags programmed to jettison from March through July, 1998. Seventeen tags

A new satellite technology for tracking the movements of Atlantic bluefin tuna.

The pop-off satellite technology provides data independent of commercial fisheries that, when deployed in sufficient quantity, should permit a critical test of the stock structure hypotheses for Atlantic bluefin tuna.

Validation of geolocation estimates based on light level and sea surface temperature from electronic tags

Electronic tags have enhanced our understanding of the movements and behavior of pelagic animals by providing position information from the Argos system satellites or by geolocation estimates using

Archival tagging of Atlantic bluefin tuna (Thunnus thynnus thynnus)

The size, power, and speed of tunas and other pelagic fishes (e.g. swordfish, marlins, sailfish) have made it a challenge to study their biology. These species are most often composed of large

Sea water is nearly opaque to electromagnetic radiation. It is, therefore, difficult to track marine animals visually over significant distances, and radio tracking is rendered impractical by


Ovaries of bluefin tuna, Thunnus thynnus, were collected from the Gulf of Mexico, Florida Straits, Middle Atlantic Bight of the western North Atlantic, and off the northeast coast of the United
