We regularly tag fish in experiments to record fish behaviour, growth and fishing catch rates.
Most of the commercial species have been subject to tagging on all major fishing grounds so there is always the chance of finding a tagged fish wherever you're fishing.
Mark and recapture experiments use conventional "marker" tags (i.e., not data-storage or electronic tags). They can provide valuable insights into fish migrations and stock structure, which have important implications for fishery management. They can also provide useful information on growth and, in some circumstances, exploitation rates.
Electronic data storage tags (DSTs) allow scientists to continuously record the behaviour of individual fish between the points of release and recapture. This information helps us to interpret how fish live and respond to their environment.
The recovery of our tagged fish and the success of our tagging campaigns rely on the collaboration of the fishing industry and recreational anglers.
