HORIZONTAL AND VERTICAL MOVEMENTS OF YELLOWFIN AND BIGEYE TUNA ASSOCIATED WITH FISH AGGREGATING DEVICES
vertical movements of yellowfin tuna Thunnue albaecrns and bigeye tuna T. o k w captured near fish-aggrc gating devices (FADs) were determined using pressuresensitive ultrasonic transmitters. TheExpand
Aquatic animal telemetry: A panoramic window into the underwater world
TLDR
A brave new world with a wider view Researchers have long attempted to follow animals as they move through their environment, but such efforts were limited to short distances and times in species large enough to carry large batteries and transmitters, while new technologies have opened up new frontiers in animal tracking remote data collection. Expand
Movements of tiger sharks (Galeocerdo cuvier) in coastal Hawaiian waters
TLDR
The data suggest that Hawaiian tiger sharks move within large home ranges and that they can efficiently navigate between distant parts of their range, even when this requires crossing open ocean waters. Expand
Is it good or bad to fish with FADs? What are the real impacts of the use of drifting FADs on pelagic marine ecosystems?
TLDR
It is shown that catching juvenile tuna around FADs does not necessarily result in overfishing of stocks, although more selective fishing techniques would likely help obtain higher yield and encourage RFMOs to expand and improve their FAD management plans. Expand
Physiological and behavioural thermoregulation in bigeye tuna (Thunnus obesus)
TLDR
This work shows using telemetered data that free-ranging bigeye tuna (Thunnus obesus) can rapidly alter whole-body thermal conductivity by two orders of magnitude, and combines physiological and behavioural thermoregulation to expand the foraging space of big eye tuna into otherwise prohibitively cold, deep water.

Electroreception in juvenile scalloped hammerhead and sandbar sharks.
TLDR
Although the sphyrnid head morphology does not appear to confer a greater sensitivity to prey-simulating dipole electric fields, it does provide a greater lateral search area, which may increase the probability of prey encounter, and enhanced maneuverability, which might aid in prey capture. Expand
Accelerating estimates of activity-specific metabolic rate in fishes: Testing the applicability of acceleration data-loggers
TLDR
Despite initial evidence of linearity in the oxygen consumption vs. PDBA relationship, incorporating previous estimates of standard metabolic rate of hammerhead sharks suggests a non-linear fit. Expand
Horizontal and Vertical Movements of Pacific Blue Marlin Captured and Released Using Sportfishing Gear*
Despite the commercia and recreational importance of Pacific blue marlin Makaira n i M a m , little is known about their biology or behavior. This is due mainly to their large size and pelagicExpand
Daily movements, habitat use, and submergence intervals of normal and tumor-bearing juvenile green turtles (Chelonia mydas L.) within a foraging area in the Hawaiian islands
TLDR
Juile green turtles in Hawaii most likely maintain aerobic metabolism while submerged and surface before oxygen stores are significantly depleted, indicating they may have been somewhat less active at night. Expand
