General One of the key tools available for fish assessment is that of electrofishing.
Electrofishing is a reasonably simple concept to explain practically,
but theoretically it can be rather confusing. Simply, a field of
electricity is passed through the water that causes a muscle response
reaction from the fish forcing them towards the netsman. A full
explanation can be found later on this page. The main purposes for
electrofishing are stock assessment, sampling/health surveys, tagging,
catching spawners, anaesthetising or eliminating species Protocol Example from Aquatic Bioindicators Survey for Hornsby Shire Council, 31st October 2000 Case studies NSW Fisheries DLWC People Contacts Richard Denham Organisation contact Department of Infrastructure, Planning and Natural resources |
