BLS6 heart rate workshop: Guest speakers confirmed
In our May newsletter we announced an upcoming workshop on using our leadless implantable heart rate loggers to measure heart rate in mammals, fish and birds at the 6th International Bio-logging Symposium in Konstanz, Germany, on September 25-29.
The workshop will take place on Wednesday September 27 at 9AM-4PM. Registration will be possible at the conference.
Joining us for the workshop are some experienced users who will present how they have used the loggers in various animal models.
The speakers are, in order of appearance:
Implantation of heart rate loggers in large mammals; bears, reindeer and moose
Alina Evans, Inland Norway University of Applied Science
Validating heart rate measurements in domestic sheep
Boris Fuchs, Inland Norway University of Applied Science
Heart rate measurements in Blackbirds
Nils Linek, Max Planck Institute of Ornithology
Heart rate measurements in sockeye salmon and smallmouth bass
Tanya Prystay, Fish Ecology and Conservation Physiology Lab, Carleton University
Heart rate measurements in Rainbow trout, Arctic char and Atlantic Cod
Albin Gräns, Swedish University of Agricultural Sciences
For more information on the workshop please see the symposium program or contact us.

Increased Distribution of Juvenile Pacific Herring in Shallow and Fresh Water
Sean Lewandoski and Mary Anne Bishop at the Prince William Sound Science Center have recently published a paper outlining their research on juvenile Pacific herring distribution and its environmental and geospatial factors. Up until now there has been little research on the subject.
Data sampled at different locations
The research was conducted at Prince William Sound which is located on the south coast of Alaska. There the juvenile Pacific herring was sampled at nine different locations during November 2013, 2014 and 2015. In addition, herring was sampled during a 7 month period at Simpson Bay. All the samplings took place during night-time
The herring was caught using a midwater trawl. Star-Oddi's DST CTD was fitted on the trawl head rope to collect data on depth, temperature and salinity. Once onboard, the fish was measured to determine its age. Herring shorter than 105mm was classed as age-0 (in its first year of life) and fish measuring between 106-150mm was classed as age-1.
Juvenile herring keeps at fresh and shallow water in proximity to eelgrass beds
The study revealed that there was a close link between the distribution of age-0 Pacific herring and the presence of eelgrass beds. The herring preferred to stay in shallow water, below 35.4m, and its distribution was greater in fresher water. The long term study at Simpson Bay also revealed that while age-1 Pacific herring moved to the outer bay in the spring months, the age-0 herring preferred to stay in the inner bay.
