The deployment of electronic data storage tags that are surgically implanted or satellite-linked provides marine researchers with new ways to examine the movements, environmental preferences, and physiology of pelagic vertebrates. We report the results obtained from tagging of Atlantic bluefin tuna with implantable archival and pop-up satellite archival tags. The electronic tagging data provide insights into the seasonal movements and environmental preferences of this species. Bluefin tuna dive… 

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.


SUMMARY The successful deployment in recent years of electronic tag technology on Atlantic bluefin tuna has improved our ability to examine their movements throughout the North Atlantic and

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

Seasonal Movements, Aggregations and Diving Behavior of Atlantic Bluefin Tuna (Thunnus thynnus) Revealed with Archival Tags

The high concentrations of bluefin tuna in predictable locations indicate that Atlanticbluefin tuna are vulnerable to concentrated fishing efforts in the regions of foraging aggregations and habitat utilization.

Electronic tagging and population structure of Atlantic bluefin tuna

The results are consistent with two populations of bluefin tuna with distinct spawning areas that overlap on North Atlantic foraging grounds, and Restrictions on the time and area where longlining occurs would reduce incidental catch mortalities on western spawning grounds.

Annual migrations, diving behavior, and thermal biology of Atlantic bluefin tuna, Thunnus thynnus, on their Gulf of Mexico breeding grounds

It is demonstrated that the movement patterns, diving behavior, and thermal biology of Atlantic bluefin tuna change significantly at different stages of the breeding migration and can be used to define spawning location and timing.

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

Spawning Behaviour and Post-Spawning Migration Patterns of Atlantic Bluefin Tuna (Thunnus thynnus) Ascertained from Satellite Archival Tags

A unique diving pattern was found on the majority of nights while the fish stayed at the spawning ground; it consisted of frequent and brief oscillatory movements up and down through the mixed layer, resulting in thermal profiles characterized by oscillations about the thermocline.

Habitat use in Atlantic bluefin tuna Thunnus thynnus inferred from diving behavior

To examine habitat use in Atlantic bluefin tuna Thunnus thynnus, we used time series records from 20 archival tags and 7 pop-up satellite archival tags. Daily vertical profiles were classified into 3



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.

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

Spawning site fidelity in Atlantic bluefin tuna, Thunnus thynnus: the use of size-frequency analysis to test for the presence of migrant east Atlantic bluefin tuna on Gulf of Mexico spawning grounds.

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

A Commentary on Western Atlantic Bluefin Tuna Assessments

Abstract Intense fishing for bluefin tuna Thunnus thynnus in the western Atlantic Ocean began in the 1960s, when landings peaked at nearly 20,000 metric tons (mt). During the 1970s, landings averaged

Elephant seals : population ecology, behavior, and physiology

This study of the elephant seal brings together an international group of scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals.

An assessment of light-based geoposition estimates from archival tags

Digital signal processing is investigated as a method of increasing the signal-to-noise ratio of the light record and two approaches to estimating geoposition based on estimating either the time of maximal rate of change in light intensity or the time that a reference light intensity is reached are described.

Bluefin Tuna Warm Their Viscera During Digestion

Acoustic telemetry showed that stomach temperature from large bluefin tuna, Thunnus thynnus, held in an impoundment, changes markedly during feeding, which should speed digestion and allow the tuna to feed frequently when food is abundant.

Since the cooling and oxygen uptake are linked by the physical process of the passage of blood through the gills, it would seem impossible for a fish to maintain its body temperature more than one degree above that of its environment by metabolic processes alone.

Why do tuna maintain elevated slow muscle temperatures? Power output of muscle isolated from endothermic and ectothermic fish.

It has been hypothesised that regional endothermy has evolved in the muscle of some tunas to enhance the locomotory performance of the fish by increasing muscle power output. Using the work loop
