In regards to the electronic tagging devices, what is the current longevity of some of these devices; specifically, how long does a power cell usually last?
Furthermore, I realize that miniaturization is an obvious focus, but some of the devices seem rather large and I wonder if fluid flow dynamics (to reduce drag) were a consideration in development.
What impact do environmental changes have on migration and feeding patterns that we see in the paper?
ReplyDeleteCan sewage effluents be mapped as well? Fishing and shipping lanes?
How has changes in seawater temperature altered the density and residency patterns (or has it)?
