Abstract Individuals store energy to balance deficits in natural cycles; however, unnatural events can also lead unbalanced budgets. Entanglement fishing gear is one example of an but relatively common circumstance that imposes energetic demands a similar order magnitude and duration life‐history such as migration pregnancy large whales. We present two complementary bioenergetic approaches estimate the associated with entanglement North Atlantic right whales, compare these estimates life...
Abstract To determine effectiveness of Seasonal Management Areas (SMAs), introduced in 2008 on the U.S. East Coast to reduce lethal vessel strikes North Atlantic right whales, we analyzed observed large whale mortality events from 1990–2012 geographic region “Ship Strike Rule” identify changes frequency, spatial distribution, and spatiotemporal interaction since implementation. Though not directly coincident with SMA implementation, vessel‐strike mortalities significantly declined 2.0...
Concern over the well-being of marine mammals at sea has focused on intentional harvests, both in terms individual welfare and population sustainability. Unintentional mortalities from fishing gear entanglement are primarily seen as a risk to viability. Additionally, larger whales breaking free of, subsequently carrying, fixed trap net subject very slow demise, averaging 6 months case North Atlantic right whale ( Eubalaena glacialis ). Chronic cases can involve impaired foraging, increased...
Attaching bio-telemetry or -logging devices (‘tags’) to marine animals for research and monitoring adds drag streamlined bodies, thus affecting posture, swimming gaits energy balance. These costs have never been measured in free-swimming cetaceans. To examine the effect of from a tag on metabolic rate, cost transport behavior, four captive male dolphins (Tursiops truncatus) were trained swim set course, either non-tagged (n=7) fitted with (DTAG2; n=12), surface exclusively flow-through...
Abandoned, lost or discarded fishing gear (ALDFG) comprises a significant amount of global marine debris, with diverse impacts to environments, wildlife, and the industry. Building evidence on ALDFG is critical holistically understand debris issue, inform development solutions that reduce amounts sources recover existing gear. Substantial work has been continues be undertaken around world collect data ALDFG, much which remains unpublished. To provide picture we organized technical session...

There has been less attention devoted to impact human welfare individual mammals, although ethical reasoning suggests that an is important regardless abundance or population health. growing interest in developing methodologies frameworks could be used obtain overview threats animal welfare. This paper shows steps taken...
Vessel strikes are the primary source of known mortality for endangered North Atlantic right whale ( Eubalaena glacialis ). Multi‐institutional efforts to reduce associated with vessel include vessel‐routing amendments such as International Maritime Organization voluntary “area be avoided” (ATBA) in Roseway Basin feeding habitat on southwestern Scotian Shelf. Though relative probabilities lethal have been estimated and published, absolute remain unknown. We used a modeling approach determine...
The accurate estimation of field metabolic rates (FMR) in wild animals is a key component bioenergetic models, and important for understanding the routine limitations survival as well individual responses to disturbances or environmental changes. Several methods have been used estimate FMR, including accelerometer-derived activity budgets, isotope dilution techniques, proxies from heart rate. Counting number breaths another method assess FMR cetaceans, which attractive its simplicity ability...
All three extant right whales (Eubalaena australis (Southern; SRW), glacialis (North Atlantic; NARW), and japonica Pacific; NPRW)) were heavily exploited, the status of two northern hemisphere species remains precarious. Limited gains made by NARW have been reversed urgent changes to management approaches are needed avert extinction. By contrast, some SRW populations recovering. Given their close phylogenetic relationship, morphological, demographic, ecological similarities, contrasting...
Abstract Protracted entanglement in fishing gear often leads to emaciation through reduced mobility and foraging ability, energy budget depletion from the added drag of towing for months or years. We examined changes kinematics a tagged entangled North Atlantic right whale (Eg 3911), before, during, after disentanglement on 15 January 2011. To calculate additional forces energetic demand associated with various configurations, we towed three sets attached load‐cell tensiometer at multiple...
Abstract Lethal and sublethal fishing gear entanglement is pervasive in North Atlantic right whales ( Eubalaena glacialis ). Entanglement can lead to direct injury likely incur substantial energetic costs. This study (1) evaluates drag characteristics of entangled whales, (2) contextualizes measurements for individual (3) quantifies the benefits partial disentanglement. A load cell measured forces on 15 sets removed from a towed satellite telemetry buoy, 200 m polypropylene line as it was...
Abstract North Atlantic right whales spend their summer months foraging primarily in American and Canadian waters on high‐energy‐density prey. Here, they rapidly accumulate store energy obtained within a few to support future migrations reproduction while fasting. High drag from ram‐filter strategy places limit what prey densities will be energetically efficient target. Our understanding of the volume prey‐laden water filtered by during dive or bout, information use decide forage not, has...
Abstract Little quantitative information on the behavior, health, and activity level of managed marine mammals is currently collected, though it has potential to significantly contribute management welfare these animals. To address this, high‐resolution motion‐sensing digital acoustic recording tags ( DTAG s) collected data from animals under human care n = 5) during their daily routine, classification algorithms were used for gait analysis event detection. We examined ~57 h five bottlenose...
Abstract Drag force acting on swimming marine mammals is difficult to measure directly. Researchers often use simple modeling and kinematic measurements from animals, or computational fluid dynamics (CFD) simulations estimate drag. However, studies that compare these methods are lacking. Here, simulation physical experiments were used drag forces gliding bottlenose dolphins ( Tursiops truncatus ). To facilitate comparison, variable loading no‐tag, tag, tag + 4, 8 ) was increase in both...
Instrumenting animals with tags contributes additional resistive forces (weight, buoyancy, lift and drag) that may result in increased energetic costs; however, metabolic expense can be moderated by adjusting behaviour to maintain power output. We sought increase hydrodynamic drag for near-surface swimming bottlenose dolphins, investigate the effect of instrumentation. In this experiment, we whether (1) rate increases systematically loading from different sizes or (2) tagged individuals...

Bio-logging technology is becoming an ever more common tool for persistent monitoring of people and animals in their natural environment. As a result, the volume type information collected by these embedded sensing systems continues to increase, making algorithms that can accurately efficiently classify parameterize behavior from sensor data essential. How best extract multiple sensors remains open question. The problem becomes challenging cases where only sparse concurrent human...
Fish swimming energetics are often measured in laboratory environments which attempt to minimize turbulence, though turbulent flows common the natural environment. To test whether and kinematics of shiner perch Cymatogaster aggregata (a labriform swimmer) were affected by two flow conditions constructed a swim-tunnel respirometer. A low-turbulence was created using respirometry setup with straightener fine-mesh grid velocity fluctuations. high-turbulence condition allowing large fluctuations...
Abstract Great whales have been detected using very‐high‐resolution satellite imagery, suggesting this technology could be used to monitor in remote areas. However, the application of method whale studies is at an early developmental stage and several technical factors need addressed, including capacity for species differentiation maximum depth detection water column. Both require knowledge spectral reflectance various just above sea surface, as when bodies break surface breath, log or...
