Electronic and Satellite Tags
In part 2 of the “History of Tagging” segment we look at the development and use of electronic tags. The development of electronic tags opened up a wide range of new possibilities and allowed more detailed behavioural studies on short-term movements, migrations, diving behaviour and habitat use. Sharks in particular were identified as strong candidates […]
A History of Tagging
In this segment we will cover the history of fish tagging from its origins in the early 1600’s up to modern day shark tagging projects. For centuries humans have tried to develop non-destructive ways of monitoring the movements and dynamics of fish populations largely for the purpose of fisheries management, it was this need that […]

Below we explain the impact that tagging has to the body of an elasmobranch in order to explain that these ‘sores’ are formed from scar tissue as an auto immune response from the fish. As tagging is a popular method for studying […]
