Can marine mammals hear acoustic tags?
There have been studies conducted over the past several years, showing that some marine mammals can potentially hear acoustic tags operating between 50 and 85 kHz. However, with over 40 years of acoustic telemetry studies to date, we are unaware of any study or any evidence that has shown that the ability to hear some acoustic tags can or will translate into modified foraging behavior in the wild or that tagged fish in the wild would be predated upon at higher rates than non-tagged fish.
There are many varieties of marine mammals and while it is likely that some can hear tags in certain circumstances, the natural environment would make this extremely challenging. The tags used emit very short pulses at random and infrequent intervals and at relatively low power levels and are attached to a wide variety of species, both prey for and predators of marine mammals. Considering that the natural environment is abundant with louder acoustic noise sources, it is unlikely that tags could be heard in any consistent manner.

Movements of a Non-indigenous Barbus barbus Population
Species: European barbel, Barbus barbus
European barbel (Barbus barbus) has one of the largest seasonal home ranges of all riverine fish and is an important recreational angler-caught species; hence it is an interesting and valuable study species (Ovidio et al 2007, Twine 2013). Analysis will focus at the individual level for the fish, initially determining their maximum distance travelled and total distance travelled, before analyses are completed in more depth in relation to diurnal and seasonal events, and winter flood events. Variability in movements will also be tested against sampling method (as angling tends to capture ‘bold’ individuals, i.e. those more likely to have high vagility) and stable isotope data (to identify if variability in movements has a trophic basis). There are also several potential barriers to movement within the study area which will be assessed for how they have affected home range and under which conditions they are passable.

OTN Arctic Cumberland Sound Array
Species: Arctic skate, Greenland halibut, Greenland shark, Ringed seal
Cumberland Sound, on southern Baffin Island, supports a wide variety and number of arctic fish, seabird and marine mammal species and a community of 1,400 people (Pangnirtung). Significant changes have occurred in the Cumberland Sound ecosystem in the recent past, which are likely due to climatic changes. Ice condition is the most obvious change as the duration of ice cover and the extent of land-fast ice have been reduced. These changes in arctic ice cover will likely have serious impacts on the trophic interactions and movements of arctic species. This project will target the spatial, seasonal and temporal interaction of fish and marine mammals in the Cumberland Sound ecosystem. This will be accomplished by overlying the spatial and temporal movements of key fish and marine mammal species using a combination of satellite tags, acoustic (V6) and chat tags, and an array of VR2W receivers in the Sound, with current and on going studies of trophic interactions using stomach contents and chemical tracers (stable isotopes) from numerous species and levels of the trophic system.

Cook Inlet Telemetry Study
Species: Chinook salmon, Sockeye Salmon
David Welch and his team at Kintama conducted a pilot telemetry study in Cook Inlet and adjacent rivers to resolve key uncertainties about how best to exploit abundant sockeye salmon runs while protecting weak Chinook salmon runs. The study was focused on movements of returning adults and involved the design and deployment of a custom tracking array. Despite the rigors of the environment (Cook Inlet has the second largest tides in the world) 100% of tagged animals detected entering the two rivers involved in the study were first detected on the marine array, and 100% of tagged adults detected in the lower Kenai River were subsequently detected on VR2s placed higher up-river. Excellent technical performance during the pilot study meant that the biological analysis could proceed with little uncertainty.
