Dear Fish-Ecologists,
I would like to add to Hans Guttman's enquiry from the point of view of
using electrofishing to study populations of species of conservation
concern, either endangered or which are considered at risk. I would be
extremely interested in any views/results of any work using this method
on endangered/threatened fish populations.
Regards,
Patricia Almada-Villela
